Bleach has been studied for the first time by a French chemist named Claude Louis Berthollet in 1775. His factory was based in Paris in the district of… Javel! That is why the French are calling it: Eau de Javel (Javel Water).

At first, bleach was used for laundry and as a fade. From 1820, a pharmacist named Antoine Germain Labarraque studied more deeply its disinfecting properties . In the XIX Century, it was commonly used as a disinfectant and water treatment. The NASA used bleach during the Apollo program to disinfect the Apollo XI rocket after its return, in order to avoid contaminating Earth with potential dangerous viruses!
What is Bleach?
Bleach is composed of sodium hypochlorite (NaClO). For chemistry fans, its chemical formula is as follows:
Cl2 + 2 NaOH → NaCl + NaClO + H2O.
For those who don’t like chemistry, well… the formula is the same!
What’s new with Bleach?
Nowadays, bleach is still used as a disinfectant. Stabilized formulas enable to combine the disinfecting ability of chlorine together with the cleaning ability of surfactants.

FORMATIVE ASSESSMENT
A training cannot be complete without a formal evaluation! This is why we offer each participant a quiz of 10 questions before issuing a superb attestation!
Myosan TB is a ready-to-use disinfectant cleaner has a broad spectrum virucidal claim. In accordance with Health Canada’s recommendations, we are authorized to make an indirect claim against SARS-CoV-2, the virus responsible for COVID-19 [1] , [2] .
MYOSAN TB
Myosan TB can therefore be used as a disinfectant against SARS-CoV-2, the coronavirus that causes COVID-19, since it is qualified as part of Health Canada’s approach to emerging viral pathogens for hard-to-use surface disinfectants. against SARS-CoV-2.
Coronaviruses are enveloped viruses, which means that they are among the easiest types of virus to kill with an appropriate disinfectant, when used according to the label directions for use.
To obtain Myosan TB, contact us at (514) 645-2753, or infos@lalema.com, or visit www.myosantb.com. Thank you.
SARS-COV-2 (COVID-19)
Coronavirus are enveloped viruses, which means that they are among the easiest types of virus to kill with an appropriate disinfectant, when used according to the label directions.
VIRUCIDAL
Said of a substance capable of destroying a virus. A virus is an organism made up of at least two things: genetic material (DNA) and proteins. Being dependent on another organism to reproduce, the virus must find a viable host to multiply.
TUBERCULOSIS
A tuberculocidal agent is a real killer of tuberculous bacilli, tuberculosis creating an infection with the mycobacterium Mycobacterium tuberculosis.
BACTERICIDE
Said of a substance having the capacity to kill bacteria. A bacterium is a single-celled living organism composed of a membrane, genetic material and cellular machinery. It differs from the virus in that it does not need a host to reproduce; the bacteria is an independent organism.
FUNGICIDE
Said of a substance that destroys fungi. Fungi, commonly called fungi, are sometimes unicellular, sometimes complex multicellular organisms. Composed of a nucleus, a membrane and a cellular machinery, the fungus reproduces itself.
It’s very simple, all the subtitles of this post are false. Fortunately, we are helping you get the facts out about COVID-19 (coronavirus).
CODIV-19 CAN BE TRANSMITTED BY MOSQUITO BITES
FALSE
The new coronavirus is a respiratory virus that spreads mainly through contact with an infected person, through respiratory droplets emitted when a person, for example, coughs or sneezes, or through saliva or secretion droplets nasal passages. To date, there is no information or evidence suggesting that 2019-nCov could be transmitted by mosquitoes. To protect yourself, avoid close contact with someone who has a fever or cough, and practice good hand and respiratory hygiene.
COLD WEATHER AND SNOW CAN KILL NEW CORONAVIRUS
FALSE
The normal temperature of the human body remains around 36.5°C and 37°C, regardless of the outside temperature or weather. Therefore, there is no reason to believe that cold weather can kill the new coronavirus or other pathogens. The most effective way to protect yourself from 2019-nCoV is to wash your hands frequently with an alcohol-based product or with soap and water.
THE NEW CORONAVIRUS (COVID-19) CAN PROJECT UP TO 8 METERS FROM A PERSON WHO IS TUSTING OR SNEAKING
FALSE
Respiratory droplets project up to 1 meter from a person who coughs or sneezes.
When a person infected with COVID-19 coughs or sneezes, the virus is expelled into droplets that can travel a certain distance from that person. Therefore, to protect yourself from any respiratory virus, avoid close contact with someone who has a fever or cough, and wash your hands frequently with hydro alcohol or soap and water.
HAND DRYERS ARE EFFECTIVE IN KILLING COVID-19
FALSE
Hand dryers are not effective in killing COVID-19. To protect yourself from the new coronavirus, you should frequently wash your hands with a water-based product or with soap and water. Once your hands are clean, you should dry them thoroughly with paper towels or a hot air dryer.
CAN EAT GARLIC HELP PREVENT NEW CORONAVIRUS INFECTION?
FALSE
On one positive side, it may drive colleagues away. Garlic is a healthy food that may have certain antimicrobial properties. However, there is no evidence in the current epidemic that consuming garlic protects people from the new coronavirus.
DOMESTIC ANIMALS CAN SPREAD THE NEW CORONAVIRUS
FALSE
There is currently no evidence that pets / pets such as dogs or cats can be infected with the new coronavirus. However, it is always a good idea to wash your hands with soap and water after contact with pets. This protects you from various common bacteria such as E. coli and Salmonella that can pass from pets to humans.
ANTIBIOTICS ARE EFFECTIVE IN PREVENTING AND TREATING NEW CORONAVIRUS INFECTION
FALSE
Antibiotics do not work against viruses, but only against bacteria.
The new coronavirus (COVID-19) is a virus and, therefore, antibiotics should not be used as a means of prevention or treatment.
However, if you are hospitalized for COVID-19 infection, you may be given antibiotics because bacterial co-infection is possible.
A rare virus spread by fruit bats, which can cause flu-like symptoms and brain damage, has killed 10 people in southern India, health officials said on Tuesday, with at least two more cases being monitored.
…
The virus was first detected in Malaysia in 1998, and India’s eastern state of West Bengal has suffered two outbreaks in the last decade, killing 50 people, the WHO has said.
There has been a another preivous outbreak in Bengladesh in 2004. It would be the third outbreak if confirmed.
Is there any risks in Canada?
The risk to Canadians is considered to be low as there are no species of fruit bats in Canada. However, people working with swine in Southeast Asia should be aware of the risk.
Mode of transmission of Nipah Virus
Public Health Canada states that:
The mechanism for the transmission of the virus from fruit-bats to animals is unknown, but may involve consumption of fruit contaminated with urine or saliva from infected bats. Transmission from animals to humans appears to occur by direct contact with contaminated tissues/body fluids of infected animals, especially pigs. Other infected animals, such as cats and dogs, may also be involved in spreading the virus. Human to human transmission is likely to occur by direct exposure to an infectious inoculum shed in the respiratory secretions of the infected individual, as well as by close physical interaction and frequent contact with the infected individual’s saliva.
…
Human-to-human transmission has been documented in several of the more recent outbreaks in Bangladesh, before which human-to-human transmission was considered to be a rare event
Influenza is a stubborn virus. Moreover, every year, the virus is changing and it’s another race against time to produce a new vaccine, often composed of several strains, which will be able to protect the most vulnerable population such as young children, the elderly and sick people.
AN ENCOURAGING RESEARCH on INFLUENZA
According to the article by Radio-Canada:
At Laval University, Gary Kobinger’s team is testing a new influenza vaccine, which could provide better protection and long-term immunization. The formula incorporates much of the circulating influenza strains over the last 20 years.
A first clinical trial to test the safety of the vaccine ended a few months ago. According to the researchers, it shows that the product does not cause significant side effects.
The effectiveness of vaccines against influenza (the flu) is also limited especially when we guess wrong the strain that will be the most virulent that year!
THE IMPORTANCE OF HAND WASH
We are all at one point exposed to the flu virus. A good way of individual prevention is to put on your hat on and tie your coat. I am joking. On the other hand, regular hand washing before meals, after the toilet and even just when arriving at work or at home is really an effective way against the spread of the virus.
Regular hand soaps like Utopia or antibacterial soap like Utopia AB do the trick.
Did you know that our soaps do not contain any: methyisothiazolinone?
THE IMPORTANCE OF SURFACE DISINFECTION
Cleaning worker also plays a very important role in the winter period when it comes to disinfecting surfaces. Specialty products such as the Ali-Flex line of product offers many benefits:
Would we be ready to face an epidemic of bubonic plague?
In Madagascar, the government has recently imposed two days ago new emergency measures to stop a plague epidemic. It has been declared 24 dead since 1 month1.
What is the bubonic plague?
The plague is a bacterium Yersinia pestis, present in rodents as rats are often passed to humans by infected fleas.
According to Health Canada:
The incubation period of the plague varies from one to ten days.
Whatever the form, the illness always starts with flu-like symptoms (fever, chills, muscle aches, weakness and headaches) and can also cause nausea, vomiting, diarrhea and abdominal pain.
If left untreated, the mortality rate can reach 50%.
SURFACES DISINFECTIONS
According to Health Canada2, in the event of a spill or contaminated surfaces:
Let the aerosols fall; wear protective clothing, carefully cover the spilled material with paper towels and apply 1% sodium hypochlorite from the periphery to the center; allow to act for a sufficient period (30 minutes) before cleaning
Plague is affected by many types of surface disinfectants such as:
For a long time, cleaning has been all about the look; fresh smell and the absence of stains or dirt were the criteria to determine that a place is clean. Today, these criteria are still generally accepted in environments such as offices and classrooms.
It’s common knowledge, however, that microbes (bacteria or viruses) invisible to the human eye represent a risk for spreading infections. Take the example of the influenza virus: it can survive for up to 48 hours on a hard surface!
Without cleaning and disinfection procedures or a quality check procedure, microbes can survive in hospital environments.
Three key elements have to be considered in order to perform an infective risk analysis:
Is the patient carrying a disease agent? Disease agents are classified based on their spreading capacity and their virulence. The choice of a disinfectant will be based on this.
Do the functional activities of a sector represent a risk of spreading infections from the environment? E.g.: food service, offices, Intensive Care, etc.
The intensity of contact is related to the traffic and the surfaces that are more likely to be touched. E.g.: bathroom fittings.
Infective Risk Analysis
Cleaning in hospitals allows reducing risks of infection among patients. This is not the only factor, of course: good personal hygiene habits such as washing hands and the use of protective equipment such as overalls, gloves, masks, or protective glasses are also important elements.
For this reason, interventions must be well coordinated in order to have a good surface maintenance plan. The manager of hygiene and cleanliness should therefore take into account:
The type of place associated to the level of risk
The tasks to perform
The required cleaning frequency
If well applied, a detailed estimate allows validating the cleaning performance.
The global approach is going to be determined by type of place:
Regular eradication (e.g.: operating rooms)
Keeping environmental effects as light as possible (e.g.: low infection risk such as individual office spaces)
Balance of microorganisms. This approach is based on the competition between good and bad microbes. The presence of good microbes guarantees less space for bad microbes to grow (e.g.: living environments)
Green cleaning. Approach that uses less toxic products
Review and improve arrangements and/or surfaces (during conception or renovation)
The Cleaning Staff: key to success
The hygiene and cleanliness staff represents a key element in the fight against infections in hospital environments. Often little valued, their role in the global strategy of surface cleaning is extremely important.
The hygiene that comes from the work of the cleaning staff requires a high performance level. In order to reach that, the executing staff and the managers need to master all the different elements representing this profession.
Cleaning products and equipment are undeniably crucial in order to ensure performance during the environment asepsis of any establishment. Therefore, it is important to associate the day-to-day actions of the cleaning staff with a range of products and equipment that favor the quality of their performance.
Since several years, partly due to the devotion and the involvement of many members in the healthcare system, we take into consideration new factors:
Provincial training
Establishment of an AEP hygiene and cleanliness in healthcare environments of 630 hours now offered by many school boards
Provincial day of hygiene and cleanliness
Etc.
Having said this, the hygiene and cleanliness staff deserves our deepest gratitude. Thank you so much!
Work Organization
How can proper work organization contribute to the cleanliness of a hospital? How to be in the right place with the right equipment? Here are the questions we are going to answer in this post of the Cleaning in Hospitals series.
Evaluation of production needs
First, we need to assess the needs in hygiene and cleanliness. In order to do this, a standard evaluation is preferable but it needs to be adjusted based on the type of place, units, and traffic.
It is during the evaluation of needs that the hygiene and cleanliness estimate (see Cleaning in Hospitals part 2) is going to be determined. All daily, weekly, monthly, and annual tasks have to be considered.
Usually, the results are presented by production yields (square meters/hour) or FTE (Full Time Equivalent).
How to reduce time waste
How to measure productivity in a context where an important aspect of the task is moving? Actually, hygiene and cleanliness departments are almost always in the basement, whereas most of their work happens on the floors!
We increase productivity by reducing traveling.
It is for this reason that the cleaning cart needs to be as complete as possible and the water sources or janitor’s closets well stocked with supplies (i.e.: paper products or waste bags), equipment, and sanitary products.
Moreover, it is important to remember that a good entrance carpet can greatly reduce dirt.
Have a successful day!
Here are a few hints on how to have a successful day:
Establish a sequence of actions to perform in a day/week/month
Define a sequential order of rooms
Integrate linked and periodical tasks (monthly)
Make sure to have time gaps to focus on periodical tasks (dusting of high surfaces, polishing, etc.)
Minimize traveling
Work by space and not by task
Distribute tasks equitably
One look is worth a thousand words: choose a colorful plan together with some graphics instead of a list of tasks on a word file!

One can not stop the progress. The discovery of an enzyme capable of preventing the production of a biofilm, this polymeric protective layer produced by bacteria that prevents antibiotics and surface disinfectants from functioning well, could ultimately revolutionize the fight against nosocomial infections.
The team at the McGill University Health Center, which includes Dr. Donald C. Sheppard, has published a study in the journal Proceedings of the National Academy of Sciences (PNAS). Their hope is that this technology will be the subject of human clinical trials in Canada within 5 years and be used in hospitals within 10 years.
From the abstract:
We demonstrate that glycoside hydrolases derived from the opportunistic fungus Aspergillus fumigatus and Gram-negative bacterium Pseudomonas aeruginosa can be exploited to disrupt preformed fungal biofilms and reduce virulence.
What is a biofilm?
My colleague Rémi Charlebois described biofilms as follows:
Biofilms found on surfaces are often derived from a complex colony of microorganisms producing polymers that allow them to adhere better to the surface and facilitate colony life. In short, a biofilm is like a city for microbes. Man has learned to tame these biofilms and can use them to treat wastewater or produce certain molecules such as natural plastics. However, the presence of unwanted biofilms could be harmful and can lead to infections.
Biofilms are also found on the skin and medical devices. Thus, according to the article of Le Devoir:
Biofilms, a highly sticky matrix of proteins and sugar polymers made by bacteria to protect themselves, are attached to the skin, mucous membranes or the surface of biomedical materials, including catheters, tubing, heart valves and other prostheses Which become preferred entry points for infection.
In the same article, Dr. Sheppard quotes:
Biofilms are produced by molecules that defend against our immune system or against antibiotics with this shell that is 1000 times more resistant than the organisms that produce and proliferate in these biofilms.
An enzyme that acts as a “destructive machine” for biofilms
In short, the enzyme discovered was modified to destroy the biofilms instead of forming them. This is a new strategy that can reduce nosocomial infections in healthcare centers.
Watch this video about biofilms (25 minutes, french)
Recently, my friend Rémi wrote on Twitter: “Why is it so long to get rid of Polio in the world? “, Did you know that there are barely 30 cases per year in the world! Only 3 countries in the world still have Polio cases. One of these 3 countries, Nigeria is on track to succeed with no cases reported since 1 year.

Should we worry about the anti-vaccine movement?
In the report on CNN twitted by Rémi, the specialist mentions that the number of children not vaccinated in the United States is growing continuously. Will we have to wait for another epidemic?
Surface disinfection against poliovirus type 1
According to Health Canada, in its guideline – Safety and Efficacy Requirements for Disinfectants Assimilated to Hard Surface Drugs, a broad spectrum virus is defined as:
Broad-Spectrum Virucide: A disinfectant that is shown to be effective against a representative, envelope-free and hard-to-kill virus, which is also intended to inactivate other enveloped and envelope-free viruses (ie a product of which A “broad spectrum virucide” efficacy has been demonstrated).
Also according to Health Canada:
The incidence of poliomyelitis in Canada declined following the creation of vaccination programs in the 1950s. The last indigenous case of wild poliovirus infection in Canada dates back to 1977. In 1994, the World Health Organization Officially declared Canada free from wild poliovirus. The cases of paralytic poliomyelitis that have occurred in Canada since then have been associated with imported cases of wild poliovirus infection and the use of OPV.
According to the MSSS, in its guide “Disinfectants and disinfection in hygiene and sanitation: fundamental principles”
Among the viruses are those that are enveloped by a lipid layer and those that are not. These are called naked viruses. Paradoxically, this lipid-rich envelope is easily altered by chemicals, making wrapped viruses vulnerable. In contrast, naked viruses are “accustomed” to coping with outdoor conditions and are more resistant to disinfectants. Generally, if a disinfectant is active against naked viruses, such as polio, it is likely to be active against enveloped viruses, such as AIDS (HIV).
Quaternary or sodium hypochlorite disinfectants
Quaternary or sodium hypochlorite disinfectants with the “broad-spectrum virucidal” claim are effective against naked viruses such as polio.
Waste management can be a real headache especially if you work in a hospital or university! In Quebec, the legal and regulatory framework has evolved for more than 50 years and in 2017, several municipal, provincial and federal laws and regulations are in force. Let’s see how we can classify and demystify the different types of waste.

Good practices in waste management
To properly manage waste, it is imperative on one hand to be well aware of the characterization of your waste and on the other hand to know the regulations that apply to your situation.
Safe Handling
The safe handling of waste, whether at the time of its production, handling, storage or disposal, must be accomplished with appropriate protective measures for your own safety, safety of of others and protection of the environment.
Communication
Each department must also be informed of the way in which they dispose of the waste they produce in a safely manner. That’s why a good communication plan is also important!
Reduction at source
Take action by initiating gradual changes in how you manage your residual materials on the basis of the 3RV-E principle that promotes source reduction, reuse, recycling and valorise until residual materials must be eliminated.
Reducing at source is the fundamental principle of management to decrease the quantity of goods consumed, which necessarily decreases the amount of natural resources consumed.
Reuse is to give a second life to objects and use what others do not need anymore.
Recycling is the process of converting a residual material into a raw material for the manufacture of a new product
Valorisation is to give a second life to the products but in different ways, usually this is done by the biological way for example compost or energy like biofuels
Elimination when all efforts have been made in the 3RV and waste is finally disposed of.
Classification of waste by category
In industrial and institutional environments, waste is generally grouped into 7 categories:
General Waste
Non-recyclable waste with no reuse or recovery potential
Biomedical waste
Human anatomical waste
Animal anatomical wastes
Non-anatomical waste
Piercing, sharp or breakable objects that have been in contact with blood
A liquid or a biological tissue
Biological tissues, cell cultures, cultures of micro-organisms;
Live strain vaccines;
Containers of blood and blood-soaked equipment, etc.
Pharmaceutical waste
Hazardous pharmaceutical waste
Drug residues
Toxic expired drugs
Cytotoxic drugs
Non-hazardous pharmaceutical waste
Other drug residues
Non-hazardous expired drugs
Chemical waste
Chemicals from laboratories
Laboratory reagents
Laboratory solvents
Pressurized containers
Radioactive waste
Residues containing radioactive isotopes above standard
Syringes, reactors, lead cylinders (nuclear medicine)
Electronic waste (or with heavy metals)
Hardware
Computers
Screens
Cell phones
Battery
Articles containing mercury
Thermometers
Fluorescent or compact fluorescent bulbs
Recyclable waste
Paper
Cardboard
Plastic
Glass
Metal
Food and compostable residues

Several tasks accomplished by ants are similar to those of human professions such as farmer or breeder. Swiss researchers recently added a surprising task to this list: chemist!
Credit David Higgins, Unsplash
Community life
We all know that anthills are full of ants. A population of a colony can easily reach several millions. Although they may be insects, food supply, waste management and infection control are, believe it or not, a major concern for the queen of an anthill.
The chemist ant
By mixing coniferous resin with formic acid (a venom secreted by ants to combat their enemies), the mixture doubles the antifungal efficacy of the resin alone. These ants are capable of improving the resistance of the colony to pathogens. This is the first time that we have observed, apart from humans, a species mixing different compounds in order to improve their effects.
Hard surface Disinfection in the human world
At Lalema, conifer resin and formic acid are not used to make our disinfectants. On the other hand, our formulas are developed and validated by real chemists in addition to being registered with the appropriate governmental bodies.

According to ASSTSAS, falls and slips account for 18% of workers’ compensation costs in the province of Quebec. This is the third leading cause of workplace accidents in the health and social services sector and it includes all types of jobs.
Causes of workplace accidents
There are many other causes of workplace related accidents :
Fall and slide accidents
Muscle problems related to lift and flexion
Eye and skin lesions, often related to the handling of chemicals
Respiratory problems, often the result of working with chemicals and equipment
Accidental exposure to electrical hazards or biological hazards
Seven ways to make cleaning work safer
Ensure periodic review of working methods and procedures
Identify and evaluate “at risk” situations including load lifting, repetitive movements, exposure to chemicals, air quality, work organization
Determine tasks requiring personal protective equipment such as gloves, goggles, masks, protective sleeves, etc.
Wear non-slip shoes when stripping or laying floor finish
Install “wet floor” safety panels when washing floors. Remove the panels when the floors are dry.
Inspect the electrical wiring of your equipment regularly. Never pull the wire to disconnect a device.
Consider the presence of any body fluid or blood as a real biological hazard and clean up only if you have received the proper training.

Well hidden or sometimes visible, always disgusting, biofilms, as so well described by my colleague Rémi Charlebois, are defined as follows:
Biofilm is an aggregation of microbial cells, surrounded by a protective layer of extracellular polymeric matrix, which attaches itself to any surface found in the hospital environment and becomes a source of contamination. Formation of complex, multicellular communities by microorganisms is a natural phenomenon which helps bacteria or fungi to survive environmental stress such as cleaning and disinfection.
This mehode is somewhat drastic, probably very expensive certainly mostly impractical. Some industries still proceed that way in 2016. I must say that in some cases it may be the only and best solution. For example pipe sections, filters, etc.
Strong acids and bases
Hydrochloric or Peracetic acids or strong bases such as caustic are sometimes used alternatively. However, corrosivity and danger of these chemicals can damage surfaces, individual protection equipment, storage and handling can also be a challenge . Furthermore, there is always the workplace hazards.
When selecting or standardizing cleaning products, the involvement and participation of your staff is essential. It is important to set up a participatory structure (mandatory user committee) for the acquisition of products and equipment. This would not only lead to a greater accountability from the users, but it will also bring a higher degree of satisfaction.
This structure would allow managers :
To listen to users and to promote their full autonomy;
To establish internal standards for any product. Such standards should truly reflect the needs of users;
To review product stock to ensure they remain relevant;
To specify, with users, technical specifications of products for purchasing according to the standards of the institution;
To educate stakeholders on the content of standards and their use;
To enhance internal resources in terms of products and equipment.
Participatory approach for the staff with the managers
Managers and users must be trained to properly select products and their many uses to avoid handling errors, improper dilution and to grab the security concepts associated. This is an essential prerequisite which is part of a participatory process that will generate a consensus from the janitors about the choice of cleaning products and initiate actions and training of new practices.
When it comes to cleanliness, some people are mixing technical terms leading to ambiguity. It is like mixing chemicals together: That is not a good idea! To keep it simple, we’ll just give three useful definitions.
Deteriorated surfaces
A deteriorated surface shows wear off sign often caused by time or misuse.
Deterioration is one of three elements of impairment of property, the others being functional obsolescence (or obsolescence) and economic obsolescence.
Safe surfaces
Safe surface means that it is safe to health. Such surface is healthy or good for health often because of risk management. In the food industry, this is why we often refer to it as food safety.
Safe is also synonymous to hygienic !
Disinfected surfaces
Disinfection is a voluntary momentary removal operation of certain bacteria (if it comes to “all germs” we refer more to sterilization), so as to stop or prevent infection or the risk of infection or superinfection by pathogenic or undesirable microorganisms or viruses.
For example:
To sanitize a surface eliminates 99.9% of microorganisms (This is a 1,000 X reduction)
To disinfect a surface removes 99.999% of microorganisms (This is a 100,000 X reduction)
To sterilize a surface or instrument removes 99.9999% of microorganisms (This is a 1,000,000 X reduction)
Obviously, “momentarily” is a key fator because the surface will be contaminated again as soon a a contaminant will enter in contact with the it. That’s why some disinfectants have a residual effect that prolongs the action of disinfectant for a certain time.
It’s been a year and a half since we started www.ali-flex.com. From the beginning, the blog purpose was mainly to ramble about disinfection. Hence, the name of this new web site!
We know from many comments that you liked our old posts, so we brought them to this new website.
Before I forget, www.ali-flex.com is more alive than ever, but will from now on be dedicated to the Ali-Flex, Chlorinated Disinfectant Cleaner. One of the main advantages of Ali-Flex RTU is to be a disinfectant as well as a cleaning product. Ali-Flex RTU is ready to use and does not require any dilution, which allows avoiding wrong manipulations or dilution while saving time. Ali-Flex uses exclusive Certiklör Technology.
The difference with our Certiklör stabilized hypochlorite?
The name says it all: stabilized hypochlorite!
Our multidisciplinary team of skilled scientists took 2 years to stabilize the hypochlorite solution. What is the secret? I’m afraid that’s like a little like the Caramilk’s secret! All I can say is that the ingredients that uses this technology have been carefully selected and expertly designed to give hypochlorite increased stability.
And who says stabilized hypochlorite, says better disinfection, less smell and increased cleaning!
If you wish to ramble about it, do not hesitate to share this website with your collegues.
Working long hours in an upright position rings a bell to you? Back pain, stress and fatigue are your daily meals? There may be a solution for you.
First: Reduce fatigue with an anti-fatigue mat
One of the features found in this type of carpet is the presence of an absorbent foam. Has it been developed by NASA? In fact, we only need to know if it works. If fatigue is reduced and comfort is improved, then risk of injury and error is reduced.
Second: a unique environment
Anti-fatigue mats are found in dry, wet or oily environement. It is however possible to have a dry environment where there is a risk of contamination.
Most ergonomic mats designed for a dry environment have no backing as shown by the following picture:
When the mat is placed in an environment where there is a risk of contamination, for example in a intensive care unit, a nurse workstation or an examination room, this can be a real problem. Indeed, how can one ensure the disinfection of such a foam pad, an absorbent material, is located under the carpet ?
A suitable carpet to reduce fatigue for the Healthcare Environment
Pure Clean carpets (also known previously under the name Pure Ergo-by Lalema) is an ergonomic mat designed specifically for critical areas in terms of infection control.
The dilution of chemical products in housekeeping is certainly one of the aspects where the lack of knowledge is most evident.
Dilution is often misunderstood
Effectively, there are unfortunately too many housekeepers that have the habit of adding a too large quantity of chemicals to their washing solution. Therefore, if they would come to a stop for an instant, in order to realize up to which point this may be harmful to their work, this bad habit would be lost very quickly.
We must indeed remember that cleaning chemical products are conceived to reach their maximum potential with a very precise volume of water.
Consequently, we must use a dilution measuring system that should be standardized for the whole working team.
Effects of under-dilution
With respect to Health and Safety, under dilution can cause:
Dermatitis problems
Respiratory tract problems
Toxic fumes may cause cancer, difficult to prove and difficult to be recognized by the CSST.
With respect to work efficiency and surfaces, under dilution can:
Damage surfaces, since an under-diluted alkaline product will make a dull effect, by opening the pores of the floor coverings and thus allowing the deposit of alkalis. Acids, on the contrary, close the pores of the floor coverings and also burn the surface.
Leave a film on the surface that will give a continuous streaky appearance and this film being greasy will facilitate the adherence of dirt.
Cause enormous rinse problems because it will create foam in the solution container, which anyway has no cleaning effect.
Disturb disinfection efficiency.
Result in a loss of efficiency, since a well-diluted product reduces the physical demand to perform a task and favors the mechanical action.
Effects of over-dilution
Over dilution can cause:
Result in no disinfection.
Result in loss of efficiency since an over-diluted product will increase the physical workload at the expense of the mechanical action.
The right dilution is always the best solution
The use of a dilution system does not have to be complicated or costly. Portable system such as Optimixx Portable Dilution System can be used as so.

In the actual market, you can find many cleaner-disinfectants. When it comes to consumer products, you’ll find a lot of brand, most of them are ready to use. It means you do not have to dilute the product and use it as is to disinfect. For industrial and institutionnal use, most of cleaner-disinfectants are concentrated if not ultra-concentrated. In that case, why choose a ready-to-use Bleach based Cleaner-Disinfectant for institutionnal use?
Main benefit of a low-foam concentrated product
Let’s talk about a product like Ali-Flex LF, a product like this one offers a high concentration for general disinfection in hospitals. On a day to day basis, with the right dilution system, the surfactants contained in ALI-FLEX LF increase the wetting power of this chlorinated disinfectant and contribute to degrease and remove dirt from hard non porous surfaces such as countertops, walls, floors, toilets, commode chairs, etc.
Main benefit of a ready-to-use chlorinated disinfectant cleaner
When it comes to infection control, one important aspect is to reduce the risk. We know that dilution systems can sometimes be flawed and not consistant with delivery concentration. Therefore, it is crucial to obtain a consistant known concentration. That is exactly what Ali-Flex RTU can provide: a factory consistant concentration of 6000 PPM (when packaged) with a validated shelf-life.
Of course it may generate more plastic in the environnement. Recycling may then be on option to consider. At the same time, when patient’s lifes are at risk, all factors that can reduce the risk is of important value.
What are you using in your facility?
Tell us what kind of product you are using. Are you in control? Are you facing problems when it comes to stop eclosion? Surely we can help you! Let’s talk!
For a long time, cleaning has been all about the look; fresh smell and the absence of stains or dirt were the criteria to determine that a place is clean. Today, these criteria are still generally accepted in environments such as offices and classrooms.
It’s common knowledge, however, that microbes (bacteria or viruses) invisible to the human eye represent a risk for spreading infections. Take the example of the influenza virus: it can survive for up to 48 hours on a hard surface!
Without cleaning and disinfection procedures or a quality check procedure, microbes can survive in hospital environment.
Three key elements have to be considered in order to perform an infective risk analysis:
Is the patient carrying a disease agent? Disease agents are classified based on their spreading capacity and their virulence. The choice of a disinfectant will be based on this.
Do the functional activities of a sector represent a risk of spreading infections from the environment? E.g.: food service, offices, Intensive Care, etc.
The intensity of contact is related to the traffic and the surfaces that are more likely to be touched. E.g.: bathroom fittings.
Have you already performed an infective risk analysis? We can help, make sure to visit our unique offer for Diagnostic Analysis of Hospital Housekeeping Service. My next post is going to explain how cleaning allows reducing risks of infection among patients.

I would like to talk to you about the Influenza. My mother always told me: “Son, a small flu lasts a week and a big one lasts 7 days.” and she was right. Influenza is a respiratory infection that also spreads very easily. It is caused by the influenza virus.
The origin of the flu
Influenza hit human beings in China as early as around -2500 B.C. With birds, the virus goes back more than 8000 years ago.
Hippocrates had clearly described Influenza
In -2400, the writings of Hippocrates clearly describe the symptoms of the flu. And since then, history is full of influenza pandemics description. However, before 1850, the data are sometimes difficult to analyze because the symptoms of flu are similar to other diseases such as diphtheria, bubonic plague, typhoid fever and others.
It was long thought that influenza was caused by bacteria. In 1931, the virus was identified in pigs and two years later, in 1933, humans from levy on the throat of a researcher contaminated with the flu.
Discovery of the vaccine
In 1935, we managed to “grow” the virus in embryonated chicken eggs. The first clinical trials between 1936 and 1938 are inconclusive. In 1944, with support from the US Army, we obtained the first effective vaccine based on influenza virus. Research has continued since.
The vaccine in Quebec for 2014-2015 is available since November
The injectable vaccine against influenza 2014-2015 offered in the program framework contains the following three strains:
A / California / 7/2009 (H1N1)
A / Texas / 50/2012 (H3N2)
B / Massachusetts / 2/2012
The intranasal vaccine contains four strains or B / Brisbane / 60/2008 in addition to the same three strains contained in the vaccine injection.
Even if you have been vaccinated against the flu last year, you still need to receive it this year. Indeed, antibody levels fall about 6 months after vaccination against influenza, particularly in people whose immune system is weakened.
The index of influenza activity in Quebec for the week of 7 to 13 December 2014 (CDC 14-50) is HIGH tends UPWARD.
Preventive measure against the flu
If we can not escape it, there is still prevention methods:
It maintains a proper hygiene program (particularly hand washing).
It is vaccinated.
This ensures clean and disinfect surfaces regularly.
For more info on how to fight a flu epidemic (or pandemic if it degenerates there), see this presentation (in french):
The ministry of Health and Social Services estimates that in Quebec, between 80 000 and 90 000 hospitalized patients will present a nosocomial infection, which represents 10% of admitted patients. In addition to the measures suggested in the action plan on prevention and control of nosocomial infections 2010-2015, healthcare centers can count on an effective cleaning product: Clorox bleach disinfecting wipes.
Clorox Bleach Wipes are pre-humidified
Since March 2011, Clorox bleach wipes are effective for killing the spores of C. difficile after a contact time of 5 minutes. The wipes are pre-humidified with a stable solution of sodium hypochlorite diluted at 1:10, that is the recommended concentration by the American Centers of Disease Control and Prevention (CDC). They are also homologated for the destruction of 31 other pathogen agents in one minute.
Since 1877, scientists know the microorganisms can be eliminated by UV rays. Nearly 50 years later, however, they discovered the specific type of frequency that was the most damaging.
In the 1950s, researchers knew that UV rays penetrate cells and damage the nucleic acids or deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). This led to the commercial development of multiple UV disinfection devices, primarily with mercury vapor, which produces UV having the most effective frequency for the destruction of microorganisms. Today, UV disinfection devices use xenon UV rays.
UV disinfection is used in many hospitals
UV disinfection devices are used in hospitals such the ones in Vancouver and Hamilton. It is the natural evolution of the UV disinfection, to which are added the cleaning and disinfecting surface and a good dose of prevention.
Combined with touchless systems for bathrooms and public spaces, hospitals are able to reduce the number of surfaces to be disinfected to prevent nosocomial infections.
In any case, these robots do not replace the housekeeping staff but add a small sector futuristic air … don’t you see a family resemblance with this R2-D2 designed by Agent-Spiff?
Ebola is a virus. There is currently no vaccine or treatment. It causes severe disease, causing serious symptoms including vomiting and bleeding. The mortality rate can reach 90%. Primary infection comes from a contact with an infected animal and it can spread quickly.
How can you get infected by Ebola?
By coming into contact with following bodily fluids such as blood, urine, feces and vomit. Of by one of the following means: by contact with a dead victim, by ingestion of infected animal meat or by having sexual intercourse with an infected person.
What are the symptoms of Ebola?
The symptoms of Ebola are fever, headache, nausea and fatigue. It may also include bleeding from nose, mouth or eyes, coughing, diarrhea or vomiting with the possible presence of blood.
How to prevent ebola transmission
The risk of transmission of the Ebola virus in Canada is very low. However, certain precautions must be taken. The Public Health Agency of Canada also recommends that travelers avoid all nonessential travel to Guinea, Liberia and Sierra Leone.
There is a risk only if you have been in contact with sick people. In such case, if you experience symptoms, call 8-1-1 (Quebec) and inform them of your discomfort. You will be directed to the healthcare center care that can help you.
What to do to prevent the spread of Ebola virus
The Ministère de la Santé et des Services sociaux in collaboration with the Institut nationale de santé publique du Québec has issued recommendations in case of an outbreak. It is important that each healthcare center that can receive a potentially infectious patient put in place appropriate precautionary measures. Thus, it is important to have the required equipment for this type of care.
Two Canadian hospitals have recently acquired a machine enabling surface disinfection in health institutions.
The Juravinksi hospital in Hamilton has started a year trial of a robot that costs 95 000 $ that burns the bacteria with UV rays: the Xenex Robot System. The general hospital of Vancouver has also started a trial of a UV robot that is 1.65 meters tall, called the Tru-D Smart UVC, working with UV rays as well. The effectiveness of these machines relies on the properties of the UV rays, or rather on the xenon UV rays, to sterilize and kill microscopic contaminants.
Ebola outbreak
Recently, with the Ebola Outbreak, the Texas Health Presbyterian Hospital in Dallas, where 42-year-old Thomas Eric Duncan, the first person to be diagnosed with Ebola in the US, was being treated, also uses such device. But was it enough? See this other blog post from my collegue: The Dallas case rises a question: Should protocols for infection control be revised?
What about your hospital?
The goal of these robots is not to replace the cleaning staff, nor the products employed for critical disinfections, but rather to complete their work, and to avoid that a single microscopic bacteria could take the life of a person whose immune system is weak.
Is your plan ready? Is your staff trained well enough? Do you have a stabilized chlorinated cleaner disinfectant in stock?
Do not miss our next post, which is going to explain how UV disinfection works!
More about Ebola Virus
There are a lot of ramblings about Ebola in 2014 on the web, you will find these articles interesting:
JAVEL Undergroud Station in Paris. Photo courtesy of Google Street View
Bleach has been studied for the first time by a French chemist named Claude Louis Berthollet in 1775. His factory was based in Paris in the district of… Javel! That is why the French are calling it: Eau de Javel (Javel Water).
At first, bleach was used for laundry and as a fade. From 1820, a pharmacist named Antoine Germain Labarraque studied more deeply its disinfecting properties . In the XIX Century, it was commonly used as a disinfectant and water treatment. The NASA used bleach during the Apollo program to disinfect the Apollo XI rocket after its return, in order to avoid contaminating Earth with potential dangerous viruses!
What is Bleach?
Bleach is composed of sodium hypochlorite (NaClO). For chemistry fans, its chemical formula is as follows:
Cl2 + 2 NaOH → NaCl + NaClO + H2O.
For those who don’t like chemistry, well… the formula is the same!
What’s new?
Nowadays, bleach is still used as a disinfectant. Stabilized formulas enable to combine the disinfecting ability of chlorine together with the cleaning ability of surfactants.

Certiklör is a proprietary technology developed by Lalema for you. This technology ensures that you have in the bottle, an effective stabilized hypochlorite, and here to stay!
This is not really that the Romans would tell each other after a rough battle against the Gallic, but nowadays the battle is never ending and merciless against the irreducible microbes!
Certain bacteria are good for us
And yet, most of bacteria are good for us, simply think of yoghurts or biological products and you’ll see that not all bacteria must be eliminated!
In certain environments such as at home, it’s not necessary to eradicate all microbial activity on the surfaces. It’s still better do it in an operating room though!
Let’s talk about public restrooms
Whether it is in a clinic, at school, in a shopping mall, a restaurant, or even at the office, certain people are a bit reluctant to touch surfaces. And you?
Conceive the ideal restroom
In this room, you will find accessories that have been conceived based on 3 fundamental criteria:
How can proper work organization contribute to the cleanliness of a hospital? How to be in the right place with the right equipment? Here are the questions we are going to answer in this post of the Cleaning in Hospitals series.
Evaluation of production needs
First, we need to assess the needs in hygiene and cleanliness. In order to do this, a standard evaluation is preferable but it needs to be adjusted based on the type of place, units, and traffic.
It is during the evaluation of needs that the hygiene and cleanliness estimate (see Cleaning in Hospitals part 2) is going to be determined. All daily, weekly, monthly, and annual tasks have to be considered.
Usually, the results are presented by production yields (square meters/hour) or FTE (Full Time Equivalent).
How to reduce time waste
How to measure productivity in a context where an important aspect of the task is moving? Actually, hygiene and cleanliness departments are almost always in the basement, whereas most of their work happens on the floors!
We increase productivity by reducing traveling.
It is for this reason that the cleaning cart needs to be as complete as possible and the water sources or janitor’s closets well stocked with supplies (i.e.: paper products or waste bags), equipment, and sanitary products.
Moreover, it is important to remember that a good entrance carpet can greatly reduce dirt.
Have a successful day!
Here are a few hints on how to have a successful day:
Establish a sequence of actions to perform in a day/week/month
Define a sequential order of rooms
Integrate linked and periodical tasks (monthly)
Make sure to have time gaps to focus on periodical tasks (dusting of high surfaces, polishing, etc.)
Minimize traveling
Work by space and not by task
Distribute tasks equitably
One look is worth a thousand words: choose a colorful plan together with some graphics instead of a list of tasks on a word file!

The hygiene and cleanliness staff represents a key element in the fight against infections in hospital environments. Often little valued, their role in the global strategy of surface cleaning is extremely important.
The hygiene that comes from the work of the cleaning staff requires a high performance level. In order to reach that, the executing staff and the managers need to master all the different elements representing this profession.
Cleaning products and equipment are undeniably crucial in order to ensure performance during the environment asepsis of any establishment. Therefore, it is important to associate the day-to-day actions of the cleaning staff with a range of products and equipment that favor the quality of their performance.
Since several years, partly due to the devotion and the involvement of many members in the healthcare system, we take into consideration new factors:
Provincial training
Establishment of an AEP hygiene and cleanliness in healthcare environments of 630 hours now offered by many school boards
Provincial day of hygiene and cleanliness
Etc.
Having said this, the hygiene and cleanliness staff deserves our deepest gratitude. Thank you so much!
The next post is going to talk more in detail about one aspect of their profession: work organization.

Cleaning in hospitals allows reducing risks of infection among patients. This is not the only factor, of course: good personal hygiene habits such as washing hands and the use of protective equipment such as overalls, gloves, masks, or protective glasses are also important elements.
For this reason, interventions must be well coordinated in order to have a good surface maintenance plan. The manager of hygiene and cleanliness should therefore take into account:
The type of place associated to the level of risk
The tasks to perform
The required cleaning frequency
If well applied, a detailed estimate allows validating the cleaning performance.
The global approach is going to be determined by type of place:
Regular eradication (e.g.: operating rooms)
Keeping environmental effects as light as possible (e.g.: low infection risk such as individual office spaces)
Balance of microorganisms. This approach is based on the competition between good and bad microbes. The presence of good microbes guarantees less space for bad microbes to grow (e.g.: living environments)
Green cleaning. Approach that uses less toxic products
Review and improve arrangements and/or surfaces (during conception or renovation)
The next post of this series is going to talk about another key factor: the hygiene and cleanliness staff.
