Better understanding disinfection

Jimmy Tremblay

Introduction

Disinfection is the process by which microorganisms such as bacteria are eliminated or reduced. The objective of disinfection is to prevent the spread of infectious diseases by reducing the number of microorganisms present. Disinfection can be achieved in various ways, including the use of disinfectant chemicals such as alcohol-based disinfectants, quaternary ammonium compounds, sodium hypochlorite (bleach), or hydrogen peroxide.

Effective Planning and Disinfection Management

This would be the planning. We need to develop a detailed plan for management and disinfection. It is important to identify high-risk areas, determine the necessary equipment, outline the procedures to be followed, and define the responsibilities of the individuals involved in the disinfection process.

  • This is training. It involves ensuring that the personnel responsible for management and disinfection are trained in good hygiene and disinfection practices. They should be familiar with the procedures, the cleaning/disinfection products to be used, and the safety precautions to be taken.
  • This is personal hygiene. We should encourage and maintain good personal hygiene practices among the staff. This includes habits such as regular handwashing with soap, the use of hand sanitizers, and wearing appropriate protective clothing.
  • This is regular cleaning. It entails establishing a regular cleaning schedule for all surfaces and high-risk areas.
  • This is proper disinfection. It involves using appropriate disinfectants to kill germs and reduce the risk of infection.
  • This is ventilation. We should ensure good ventilation in indoor spaces to facilitate the circulation of fresh air.
  • This is waste management. We need to implement an appropriate system for waste management, ensuring the safe and hygienic disposal of potentially contaminated materials.
  • This is monitoring and evaluation. It entails establishing regular monitoring and evaluation procedures to assess the effectiveness of the management and disinfection measures. Adjustments should be made if necessary.
  • This is raising awareness among staff and relevant individuals about hygiene practices.
  • This is compliance with regulations. We must ensure that regulations regarding hygiene are adhered to and that standards are upheld. Therefore, it is important to stay informed about updates and recommendations from health authorities.
The uses/benefits of disinfectant

Eliminates germs and bacteria, ensuring a clean and hygienic environment for everyone.

Surface Disinfection: This category involves the disinfection of surfaces such as countertops, doorknobs, switches, phones, keyboards, faucets, etc. There are specifically formulated disinfectant products to eliminate germs and bacteria on surfaces. These products can be disinfecting wipes, sprays, or disinfectant solutions to be used with a clean cloth.

Hand Disinfection: This refers to the disinfection of hands to eliminate germs and bacteria that may be present. The use of alcohol-based hand sanitizers is common in this category. Hand sanitizers are usually available as gels or liquid solutions. It is recommended to rub the hands with the sanitizer for at least 20 seconds until it dries.

Medical Instrument Disinfection: This category primarily concerns healthcare facilities and medical professionals. It involves the disinfection of medical instruments such as scalpels, syringes, injection devices, probes, etc. In this case, more complex disinfection procedures may be required, such as the use of autoclaves, dry heat sterilizers, or specific chemical agents.

To conclude, disinfection is essential to ensure good hygiene in the workplace, and it requires precise steps to be properly carried out.

When we talk about disinfection, we talk about the prevention and control of infection in the environment. Therefore, equipment used for respiratory therapy is considered semi-critical. The equipment must then be cleaned and disinfected properly between patients. The WHO gives us the proper maintenance of respiratory equipment in procedures to follow. The procedures are checklists in steps of a cycle. Let’s explore all the summarized steps up to the cycle finish. And yes, the cleaning step is before the disinfection step!

Checklists for care, cleaning, disinfection and sterilization of respiratory devices

1. Perform hand hygiene

The title and image say it all

2. Don appropriate personal protective equipment

The personal protective equipment to be worn during the disinfectant preparation includes surgical mask/respirator, googles/face shield, long-sleeved fluid resistant gown/gown plus apron, rubber gloves and boots or closed work shoes.

3. Wash with detergent and rinse with clean water

The external device surfaces must be wiped with a damp cloth or disposable wipe that is soaked in detergent and clean water. Then, remaining detergent residue must be wiped off with a dry lint-free cloth. A mechanical action (scrubbing/brushing) should be used to remove visible dirt deposits and calcifications.

4. Disinfect

4a. Physical disinfection – Heat for heat resistant equipement (steam/hot-water)

A high-level of physical disinfection can be achieved with steam (e.g. autoclaving at lower temperature) or hot-water at least 121°C. This is an inexpensive and effective method for sterilization or high-level disinfection.

4b. Chemical disinfection for plastic plus other parts that can be damaged by heat

b) If the disinfection needs to be with chemicals solutions, it should be performed in a well-ventilated area and away from patients. Use a disposable wipe or a fresh cloth that is soaked in a compatible disinfectant. Hydrogen peroxide 0.5% or ethanol 70-90%. Wipe from top to bottom and avoid contact with electrical connectors.

5. Dry equipment / Rinse equipment

a) Physical equipment often has a drying feature within the machine (e.g. washer, pasteurizer or autoclave). Following pasteurization, the wet equipment is typically dried in a hot-air drying cabinet or air-dried. Make sure to carefully inspect and ensure that no water is left in the equipment.

b) If a chemical solution was used for disinfection, rinse the equipment with sterile or clean water (i.e. water boiled for 5 mins and cooled down). It is preferred to use sterile water for rinsing off residual liquid chemical disinfectant from the respiratory device.

6. Store equipment in closed packages

Last step. Title says it all.

Disposable Microfiber, The First Step In The Disinfection Process

Rémi Siv
Disposable microfiber cloth system

In the past, we have often lauded the advantage of microfiber for cleaning. This is repeated today, but with the use of a disposable microfiber as the first step in the disinfection process. Of course, we are talking about cleaning first, then disinfecting. However, the products highlighted in this article are compatible with common disinfectants. These products are Rubbermaid‘s Hygen single-use microfiber swabs and wipes.

WHAT IS A MICROFIBER AGAIN?

Microfiber is a synthetic textile fiber (polyester, polyamide or a mixture) that is very fine and light with a denomination which is less than one decitex. A microfiber (filament) is characterised by its small diameter, the nature of its fiber and its structure. Therefore, not all microfibers are the same or of the same quality. This revolutionary material has quickly become a must in the hygiene, health and automotive sectors. To know more about it, read this article, Spotlight on microfiber!

THE HYGEN LINE FROM RUBBERMAID

The Hygen line was designed specifically for the healthcare industry. It is an excellent option for any facility looking to improve its cleaning efficiency, especially during the COVID-19 period. The HYGEN disposable microfiber pad and wipe contribute to the area cleaning as the first step in the disinfection process.

Microfiber pads and wipes

Disposable Microfiber Pads HYGEN
  • They eliminate 99.7% or more of the viruses and bacteria tested to help improve cleaning efficiency. And this was tested with water only
  • Help reduce cross-contamination with disposable pads/wipes that encourage cleaning with new pads/wipes for each area or task
Disposable Microfiber Wipes HYGEN
  • They are compatible with common disinfectants, including Quat (does not bind), bleach and hydrogen peroxide
  • Built-in scrub strips are made of polyester to help effectively remove dirt

DEMONSTRATION OF THE DISPOSABLE MICROFIBER

Here’s a video from Rubbermaid Commercial Products. They demonstrated the benefit of their Hygen disposable microfiber wipe compared to a paper towel and a disinfectant wipe. They use a fluorescent marker to demonstrate and verify cleaning practices.

Thus, using this disposable microfiber with a disinfectant provides an added layer of assurance. They will clean and disinfect well your floors and surfaces by combining the microbe removal power of the microfiber with the disinfectant’s killing power.

Electrostatic disinfection

Siozen electrostatic sprayer

Since the beginning of the pandemic, demands for electrostatic sprayers have exploded as an efficient way to disinfect key touch points and ensure environmental safety. While effective on a wide range of surfaces, it is important for cleaning teams to understand how it works, the cost considerations and the best facilities for using it. Therfore, this is a free translation of Cleanlink‘s article, What to know about electrostatic spraying.

What’s electrostatic disinfection

Electrostatic spraying or disinfection is the process of spraying an electrostatically charged mist onto surfaces and objects.

The electrostatic sprayer is electrically charged, allowing the specialized solution and disinfectants to envelop and evenly coat all types of surfaces. Designed to kill germs, bacteria and various types of viruses. It is a safe, fast, effective and non-contact application to limit the risk of cross-contamination.

How does it work?

Siozen - how it works

Electrostatic sprayers use positively charged atomized particles to electromagnetically adhere disinfectant chemicals to negative target surfaces.

They use an electrode inside the sprayer to atomize the cleaning solution. The particles emerge from the nozzle as a spray that clings to any contact points it can find.

For example, no matter what angle it is used for surfaces disinfection, the droplets created by the electrostatic sprayer cause the disinfectant to cling to areas such as chairs, under tables or desks.

Although it is easy to apply, well-trained personnel is essential to ensure that the application process is optimal and safe for the staff.

What are the costs?

The cost generally depends on the type of facility as well as the size of the area to be treated.

In the long-term, electrostatic disinfection protects businesses from costly financial issues associated with contagious healthcare infections. It also reduces the costs associated with providing effective disinfectant solutions.

Is it effective against COVID-19

This depends since the electrostatic sprayer does not, in itself, kill COVID-19 or the coronavirus. The disinfectant to be used in conjunction with this technology must be on the list of disinfectants with evidence for use against COVID-19 by Health Canada. Lalema‘s Myosan TB is one of them.

What types of properties are best suited for electrostatic disinfection?

This process is perfect for a variety of property types, including office buildings, healthcare facilities, shopping centers, industrial parks, condominiums, educational facilities, and government and hospitality projects. It also reaches a vast number of areas that highly covered by bacteria, otherwise difficult to access with standard cleaning methods by applying a uniform, solid coating to all surfaces.

Electrostatic disinfection is widely used in healthcare facilities as a safe and effective process in viral infection control programs, providing non-contact cleaning, thereby limiting the spread of bacteria.

Beijing 2022 Olympic Winter are now over. Most of you have already seen video footage of the robots that cook foods, mix drinks and serve in order to avoid contamination. But have you seen the disinfection devices the staff use to disinfect most areas and objects? It’s quite futuristic, but the future is now.

Clean first, then disinfect

Rémi Siv
Cleaning with a microfiber cloth

Cleaning and disinfection have long been routine in any facility. Of course, the COVID-19 pandemic has further highlighted these operations since SARS-CoV-2 can persist on various surface materials for hours or days. Facilities have sought to improve these cleaning and disinfection practices. Therefore, it is imperative that this process be orderly. Therefore, this article addresses the importance of cleaning before disinfecting. Cleaning and disinfection should be a 2-step process to reduce the risk of transmission of environmental infections.

Clean first! Why?

Primum nitidare – “D’abord nettoyer (Clean First)”. It is a book that my coworker, Gaétan Lanthier, wrote in 2019. It is to say that this is not a new subject!

Centers for Disease Control and Prevention (CDC) cites: “cleaning is “the necessary first step of any sterilization or disinfection process” or, more
simply, you must clean first before you can disinfect.”

The CDC adds: “Cleaning is the necessary first step of any sterilization or disinfection process. Cleaning is a form of decontamination that renders
the environmental surface safe to handle or use by removing organic matters, salts, and visible soils, all of which interfere with microbial inactivation.”

It’s in the mechanical action (friction)

As the CDC mentions it: “The physical action of scrubbing with detergents and surfactants and rinsing with water removes large numbers of
microorganisms from surfaces.”

Studies have shown that friction or mechanical action is at the heart of cleaning. This facilitates the effective removal of dirt, debris, microbes and soiling, making a surface ready for disinfection if necessary.

It’s a matter of interference

The CDC defines cleaning as the “necessary first step” in any disinfection process for “at least two” important reasons: it removes any barrier between the disinfectant and the target pathogen, and it removes materials that could potentially inactivate the disinfectant.

In order to effectively kill pathogens, disinfectant chemicals must have direct contact with the pathogen; however, soils, dirt, and debris can coat or
protect microorganisms, essentially serving as a protective barrier between the chemical and the target.

The build-up to biofiolms

Another important reason to clean first before disinfecting has less to do with the immediate action of a disinfectant on a surface. Rather, it is in prevention of a future problem, namely the buildup to biofilms.

Biofilms are populations of microorganisms attached to a solid surface and protected by a “viscous layer”. This layer is an extracellular matrix of polysaccharides and non-cellular materials.

Biofilms can virtually form on any hard surface, from the countertop to the water pipe. They are involved in a range of infectious diseases.

What about touch-free technology?

Comac ULVC Electrostatic Sprayer for Disinfection

Although research has shown that many of these systems, from ultraviolet light (UV-C) to hydrogen peroxide vapor (HPV) to electrostatic sprayers, can reduce microbial contamination, experts caution that they should be used as a complement to standard manual cleaning and disinfection rather than as a replacement.

Organic matters, dirt and grimes are a limiting factor for UV-C technology.
A light or heavy organic load has a significant negative impact on the destructive efficiency of the devices.

In short, clean first with mechanical action (friction) to remove dirt, debris and microbes. The disinfection step is to be done when the interferences are removed by cleaning in order to kill microbes. This reduces the risk of transmission of environmental infections by keeping surfaces clean.

Spotlight on microfiber!

Rémi Siv
Microfiber cloths
Wipeco multi-use microfiber cloths MFC-1414/10P

As we all know, the cleaning and disinfection of premises and surfaces have never been more critical with the COVID-19 pandemic. We often talk about disinfectant cleaners, but this time the focus is on microfiber cleaning cloths and tools. Since its commercial introduction, microfiber has been part of everyday life because of its reliability and effectiveness in cleaning and wiping.

WHAT IS A MICROFIBER CLOTH?

Microfiber is a synthetic textile fiber (polyester, polyamide or a mixture) that is very fine and light with a denomination which is less than one decitex. The decitex is a unit of measurement: 1 decitex = 1 g / 10 km of yarn. In fact, the term “microfiber” is used when 10 km of yarn weighs less than one gram.

A microfiber (filament) is characterised by its small diameter, the nature of its fiber and its structure. Therefore, not all microfibers are the same or of the same quality.

This revolutionary material has quickly become a must in the hygiene, health and automotive sectors. See how it is made.

THE “STORIES” OF MICROFIBER

No one is entirely sure where and when microfiber was developed. However, here are two interesting stories/versions:

  1. According to Texasmicrofiber:
    “In the late 1950s, various spinning techniques were used to produce ultra-fine fibers. At that time, experiments had resulted in random length pieces, and the first real success occurred in Japan in the 1960s.

    Dr. Miyoshi Okamoto and Dr. Toyohiko Hikota worked on this project to finally find microfibers suitable for industrial use. Ultrasuede fiber was one of the first success stories, and reached the market in the following decade. This led to an explosion in the value of microfibers in the textile sector. »
  2. According to Maboutiqueecolo:
    “It would have been invented by the Swede Rudolf Nordine in the 1980s. The invention of microfiber is said to have come about by chance during the manufacture of “towels” for hairdressing salons. These were so absorbent that they could suck out the dye from freshly dyed hair. Nordine was quick to file a patent to protect this discovery. He was awarded a prize at the Lépine competition in 1998 for this invention at the International Invention Salon in Paris. »

USE AND EFFECTIVENESS

Microfiber has the power to clean and dust different kinds of surfaces without necessarily adding a cleaning product. This is why it can be seen as an organic and ecological product.

Microfiber cloths can be used dry or wet. First, when used dry, they attract dust and trap it in its microfibers (micro-filaments). Then, when wet (with or without a cleaning product), they trap grease and dirt.

During a pandemic, it is used with a disinfectant cleaner to disinfect surfaces. Lalema also suggests using a microfiber cloth with a tuberculocidal disinfectant. This Myosan TB starter kit is an example:

Myosan TB starter kit
Myosan TB starter kit

There are several types of microfiber products for all kinds of surfaces: cloth, pad/mop, feather duster, towel, etc.

HOW TO TAKE CARE OF THEM?

Microfibers are economical and environmentally friendly. They can be reused up to 500 times. “Avez-vous le pouce microfibre?” by Kim Beauregard is an article about the maintenance of microfibers. Unfortunately, it is in French only. But here are key elements:

  • Wash the microfibers separately from other textiles and items
  • Use a small amount of liquid laundry detergent while washing.
  • Do not use a softening agent
  • Wash them in cold or room water
  • Dry the microfibers at low temperature or without heat

So, microfiber is a revolutionary material in the world of cleaning. Whether it is used as a cloth, a pad/mop or a duster, it is the ultimate cleaning tool for cleaning and wiping in many sectors. Finally, microfiber cloths can replace disposable wipes. Use them with a disinfectant product to disinfect the surfaces in your environment.

Lalema has several microfiber products from leading brands.

Why choose a Ready-to-use Bleach based Cleaner-Disinfectant?

Gaétan Lanthier

ready-to-use-cleaner-disinfectant-nursing

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.

FIFO: First In, First Out also applies to disinfectant!

Rémi Charlebois

fifo

First In, First Out (FIFO): also applies to disinfectant!

Some of you may be familiar with the FIFO concept. FIFO is a method for organizing and manipulating goods such as food, it is also used in computer science to organize data. In the food industry, FIFO is essential in order to ensure freshness, preventing foodborne illness and controlling costs.

Can a cleaning product expire?

When it comes to disinfectant the same goes, a fresher or let’s say a newer product is better. I sometimes hear people saying that soap doesn’t expire. Even though the shelf life of soap is way greater than most food items, soaps and other cleaning products do expire. Same goes for disinfectant the active ingredient of a disinfectant whether it is quats, chlorine or peroxide will diminish over time. Hence to ensure a proper disinfection it is important to use product that are not expired. A good way to achieve this is by implementing a FIFO rotation system. By always using the oldest disinfectant that you have in inventory first, you make sure that you won’t get stuck with old and maybe expired stuff!

How to know if a cleaning product is expired?

This is a broad question… For disinfectant it is pretty easy, Health Canada and the EPA requires that all disinfectant have an expiration date on their label. Most cleaning product however does not have an expiration date and the shelf life varies greatly among them. But some signs won’t get you wrong. If the color, the odor, the consistency of the product is changed or if you see a deposit in the product it might be a good sign that the product is expired. In case of doubt, call the manufacturer, with the lot number every good manufacturer will be able to tell you if the product is expired.
