The Dawn of Garderobes: Early Medieval Restrooms

When one thinks of the Middle Ages, sanitation rarely comes to mind. However, the evolution of garderobes, the medieval restrooms, is a riveting slice of history. Far from the contemporary toilets we’re accustomed to, garderobes were dedicated hygiene spaces, built into castle walls.

The Strategic Design of Garderobes

Contrary to popular belief, these restrooms weren’t mere holes in the ground or basic outbuildings. The affluent had the luxury of using a garderobe, a small room abutting the castle walls. The term “garderobe” stems from the French “wardrobe,” referring to an astonishing practice: occupants would hang their clothing in this shaft to rid them of fleas, using the ammonia from urine.

Toilets with Multiple Roles

The design of these medieval restrooms harbored another purpose. Occasionally, daring soldiers would try infiltrating castles through garderobe shafts. Thus, these toilets turned out to be strategic defense points, but also vulnerable zones. History even records several renowned figures meeting their demise on the loo, ambushed from below.

Transitioning to Modernity

While the concept of flushing toilets might seem ancient, the first modern restroom wasn’t introduced until 1596 by Sir John Harrington. Despite this groundbreaking invention, it would take nearly another 250 years for the idea to gain widespread adoption.

Conclusion

Garderobes, testaments to medieval ingenuity, remind us that innovation isn’t a recent phenomenon. Whether for hygiene or defense strategy, these medieval toilets showcase the creativity of our ancestors. For creative, innovative and useful products, visit www.lalema.com

From Ancient China to Modern Automatic Flush Toilets: The Evolution of Toilets

Gaétan Lanthier
flush toilets

Archaeologists recently discovered fragments of indoor toilets dating back 2,400 years in northwest China. This finding suggests that the concept of toilets with flush systems existed in China for over two millennia. Researchers identified the origin of the flush toilet in the ancient city of Yuegang, a capital of the Qin Kingdom and the early Han Dynasty. They were able to reconstruct an image of the toilets, consisting of a water pit connected to a bowl that servants would refill after each use. However, the upper part of the flush system is missing, preventing researchers from determining the position of the users during their natural needs.

Archaeologists described this discovery as a “luxury item,” suggesting that it was used by important members of society. Prominent figures in the Qin Kingdom, such as Qin Xiaogong and Qin Xiangong, likely used these toilets. This discovery represents the earliest and only known flush toilets in China to date.

Prior to this finding, the earliest evidence of indoor toilets dates back to the 16th century in England when Queen Elizabeth I is believed to have used a manual wooden flush. It was only in the late 19th century that porcelain was introduced by Thomas Twyford, a prominent figure in the hygiene movement. Since the end of World War II, toilets have become a significant fixture in residences. This discovery in China reveals that the invention of the flush toilet dates back much earlier than previously thought and may have independently originated in various regions of the world.

Another significant event in 2023 was the series of earthquakes in Gaziantep, Turkey, which had a significant impact on sanitation. Andreea Afumateanu, a UN sanitary coordinator who worked on the ground, shared her experience. She highlighted the unique challenges of managing sanitary maintenance in a natural disaster context, particularly the importance of psychological support for survivors who faced significant losses​1​​2​.

Since the beginning of the earthquakes, approximately 3.3 million people have been displaced, and 2.4 million are living in temporary shelters. Overall, an estimated 15 million people have been affected by this catastrophe in some way3​.

Despite these challenges, the response from Turkish authorities and the international community has been commendable. The Turkish Ministry of Health has been actively involved, mobilizing thousands of healthcare professionals to respond to the crisis. Efforts are underway to provide safer and more hygienic accommodation, with tents being replaced by containers during the reconstruction of houses3​.

There is still much to learn about the evolution of sanitary maintenance in 2023. Further research is needed to obtain a more comprehensive understanding of developments in other regions and sectors. However, it is clear that sanitary maintenance remains a crucial priority worldwide, requiring the ongoing attention and investment of all stakeholders.

Better understanding disinfection

Gaétan Lanthier

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.

Piccadilly Circus, London, England between 1890 and 1900

The last time you brushed your teeth, watered your plants or poured yourself a nice glass of cold tap water, did you stop for a moment to think you had instant access to clean water? safe? To understand how this marvel was created, you have to go back to the beginning of the 19th century in London.

Progress makes perfect even in London

At that time, the streets of London were full of trash and excrement, and the city’s rivers were heavily polluted. All this filth and misery was not just a nuisance to the nostrils of Londoners. It was downright deadly.

Cholera outbreaks in London

The contaminated rivers were particularly dangerous. For example, between 1848 and 1854, several cases of cholera broke out in London, killing thousands. No one knew what caused it.

But there was a sudden medical breakthrough. A medical doctor, Dr. John Snow (no connection to the popular series) was mapping the spread of the disease through the city, he realized that one of the sources of the outbreak was a water utility company that was distributing the water collected downstream of the outlets. He understood that to stop the spread of cholera one had to improve the water supply.

A revolution in water management

Snow’s discovery led to a revolution in sanitation. Soon after, sophisticated clean water systems were introduced, followed by filtration and chlorination. With each of these improvements, water quality and safety have improved.

The Importance of Respecting the Recommended Dilution Rate for Cleaning Products in Healthcare Facilities

Gaétan Lanthier

It is important to respect the recommended dilution rate for cleaning products in healthcare facilities for several reasons. First, using cleaning products at the correct dilution helps to ensure that they are effective at removing dirt and germs from surfaces. If the cleaning solution is too dilute, it may not have enough cleaning power to properly disinfect the surface. On the other hand, if the solution is too concentrated, it may be too harsh and potentially damage surfaces or cause irritation to the skin.

Second, using cleaning products at the correct dilution can help to reduce the risk of health hazards. Some cleaning products contain chemicals that can be harmful if ingested or inhaled, or if they come into contact with the skin. Using these products at the recommended dilution helps to minimize the risk of exposure to these chemicals.

Finally, using cleaning products at the correct dilution can help to reduce costs. Using too much of a cleaning product can be wasteful and unnecessarily increase expenses. By using the correct dilution, you can ensure that you are using the optimal amount of product to effectively clean and disinfect surfaces, while also minimizing waste.

In summary, respecting the recommended dilution rate for cleaning products is important in healthcare facilities because it helps to ensure that the products are effective at cleaning and disinfecting surfaces, reduces the risk of health hazards, and can help to reduce costs.

How to properly clean reusable protective equipment

Gaétan Lanthier

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.

This was a summary of the Care, cleaning and disinfection of respiratory equipment in sterile services department’s article by World Health Organization.

What’s best? To clean or to disinfect?

Gaétan Lanthier

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 a real definition.

Deteriorated surfaces definition

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.

surfaces-vetustes definition

Safe surfaces definition

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 !

corridor-hopital-lalema definition

Disinfected surfaces definition

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.

Far West and its Hygiene Habits

Rémi Siv
Far West
Photo by Sarah Lachise on Unsplash

When you read the title of this article, I imagine you had much the same reaction as I did. You must have thought that hygiene habits in the Wild West must be practically non-existent! Indeed, it is difficult to imagine the hygiene habits in the Wild West when we are currently living with COVID-19.

BRIEF HISTORY AND SETTLEMENT OF THE WILD WEST

The Wild West is the most famous period in the history of the American West. This period began in 1865 after the Civil War (between 1861 and 1865) and ended in 1895. Geographically speaking, the Wild West constitutes the territories located in the west of the Mississippi. Of course, there had been several waves of settlement in the West since the arrival of the first European settlers in America. The California Gold Rush of the 1840s was the first, and the call of Manifest Destiny (the idea that westward expansion was an American right and should be guaranteed) was the second. With the development of railroads in the 1860s and improved technology after the Civil War, the west became more accessible.

THE PRESENCE OF SOAP AND SHAMPOO

According to Frank Clifford, a cowboy and drifter who wrote a memoir about his life in the American Wild West, soap existed. He spoke of “soap-weed,” which Mexican women used to wash their hair. Made from the yucca plant, the soap left hair soft, clean and shiny. Many settlers used soap made from animal fat, although it was known to be harsh and irritate the skin. However, soap was not a priority. Body odor was considered a fact of life and many believed that having pores that were too clean exposed them to germs and disease.

As for shampoo, some people used soap-weed to wash their hair when they were lucky enough to have it. Another method was the use of whiskey, which was also used as a disinfectant. It was mixed with castor oil to wash the hair, which was then rinsed with rainwater or water softened with borax.

THE INEVITABLE DUST

Outside and inside, dust was inevitable in the Wild West. Frequent and devastating, dust storms covered entire towns with thick layers of dirt and grime. Sarah Raymond Herndon, author of American stories who traveled from Missouri to the Montana area in the 1860s, quotes: “Oh, the dust, the dust; it is terrible. I have never seen it half as bad; it seems to be almost knee-deep in places […] When we stopped, the boys’ faces were a sight; they were covered with all the dust that could stick on.” The presence of so much dust, of course, caused severe respiratory illness.

THE USEFULNESS OF THE SCARF

The scarf, one of the iconic aspects of cowboy attire, was an essential and used for a multitude of purposes. It was used to protect the mouth and nose from dust (like a mask), to protect the neck from the sun, the ears from the cold and much more.

COMMON TOWELS IN SALOONS

Saloon

Towels in Wild West bars were used to wipe beer foam from customers’ mouths and beards. These shared towels were accessible to everyone near the bar counters. They were thus carriers of innumerable germs and diseases.

THE OUTHOUSES, A NIGHTMARE

Outhouse

The outhouses experience is, going into a shed built over a hole in the ground. When the hole was full, it was buried. Then, the structure would be moved to another hole. Outhouses attracted all kinds of insects because of the smell. These toilets were an easy way to catch diseases. There was no toilet paper, so people used leaves, corncobs and grass.

NOT BEING ILL WAS A MIRACLE

Wild West Camp

Eventually, due to the unsanitary conditions of the many people living in the Wild West, it was normal for diseases to affect the settlements on the American frontier. Cholera was one of the most important and was devastating to both settlers and Native Americans. Upon arrival at one camp, Sarah Raymond Herndon said, “There is no disease at all in the camp; it is wonderful how well we are doing. I hope it continues that way.”

So, it’s no surprise that the hygiene habits of that era were terrible.

This wednesday’s tale, June 29th 2022, is about one of the worst pandemics in history, the Black Death! This pandemic of plague reached Europe in 1346 via the Mediterranean basin through ships carrying goods from the Black Sea. On board these ships, in addition to cargo and passengers, there were little stowaways: flea-infested black rats carrying the bubonic plague. And so, one of the most deadly pathogens was released at the ports of Europe. Rapid and fatal, the consequences were: disease, suffering and death on a cataclysmic scale. Up to 60% of the population of Europe, the Middle East and North Africa was killed in eight years by the Black Death.

IDENTIFICATION OF THE PATHOGEN RESPONSIBLE FOR THE DISEASE

First, in 1894, the pathogen responsible for the disease was discovered by bacteriologists Kitasato Shibasaburo and Alexandre Yersin. At the same time, they discovered the plague bacillus, an elongated “rod-shaped” bacterium. They named it Yersinia pestis, a bacterium carried by fleas proliferating on rats and other small rodents. The bacilli multiply in the flea’s intestine. When the flea bites its host, it regurgitates the bacilli into the host’s body and infects it. And normally, this happens in a closed cycle between fleas and rodents. The bacteria spreads at such a rate that it kills its rodent hosts. This forced the fleas to find new hosts, namely humans. The infection spread easily. Rats were attracted to human activity, especially to food stored in barns, mills and houses.

THE SYMPTOMS

Then, the symptoms of the Black Death. The incubation period was very long, varying between 16-23 days before the first symptoms appeared. Three to five days later, the victim would die. It was too late to understand the cause of death and to be fully aware of the danger.

Nodules in the patients’ lymphatic system were affected, causing swelling in the groin and armpits. These initial symptoms were accompanied by vomiting, headaches and a very high fever that made the patients tremble.

3 FORMS OF THE BLACK DEATH

First, the bubonic plague as the most common form of the Black Death. The lymph gland was inflamed and widely known as a bubo. This gave rise to the term bubonic plague.

Second was septicemic plague, as one of the other variants of the plague. It infected the victim’s blood, causing visibly black spots under the skin. This is probably what gave the Black Death its name.

Third, the pulmonary plague which affected the respiratory system, causing the victim to cough. This facilitated the infection by droplet projection. In the medieval period, septicemic and pneumonic plagues had a 100% mortality rate.

THE EXACT ORIGIN OF THE BLACK DEATH

Finally, the origin of the Black Death pandemic. According to a study putting an end to nearly seven centuries of questioning, it would have emerged in Central Asia in Kyrgyzstan. Researchers were able to trace the source by extracting ancient human DNA from a 14th-century burial site in northern Kyrgyzstan. Of the more than 400 tombstones at this burial site, about 100 dated precisely between 1338-1339. With an epitaph mentioning “death by pestilence”, in ancient Syriac. Phil Slavin, one of the authors of the study and a professor at the University of Stirling, knew of the existence of two medieval burial sites. These burial sites located near the lake of Issyk Kul in Kyrgyzstan had been excavated at the end of the 19th century.

The researchers searched the dental DNA of seven skeletons to find the cause of death. One of the authors of the study, Maria Spyrou from the University of Tübingen in Germany, explains: “The dental pulp is a valuable source, because it is a highly vascularized area that gives a high chance of detecting pathogens in the blood”. The DNA was sequenced and compared to a database containing the genome of thousands of bacteria. The verdict: the bodies were infected by the bacterium Yersinia pestis, the bacillus responsible for the Black Death, transmitted to humans by rodent fleas.

This community had therefore been the victim of the same plague that struck Europe a few years later. Analyses of the Yersinia pestis genome also revealed that it was an ancestral strain of the bacterium. It was the one at the base of the “genetic tree” of the plague. This Christian community, ethnically diverse (Mongols, Uyghurs…) practiced long-distance trade. Phil Slavin argues, “Living in the heart of the Silk Roads, they must have traveled extensively, which played a role in the spread of the epidemic via the Black Sea.”

Can you imagine a pandemic without appropriate hygiene programs/guidelines, vaccines and hand sanitizers or surface disinfectants?

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.

The proper maintenance of respiratory equipment

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.

Disinfection in 3D

Rémi Siv

Reading time: 2 mins

Building managers are learning a lot about hidden pathogens with new 3D imaging technologies now available in North America. They are learning especially a lot in healthcare, education sectors and foodservice industry.

Essentially, these systems create a map which indicates the locations and amounts of pathogens on a surface. According to a press release from the infection prevention technology company, Optisolve, what has evolved in this learning is the “3Ds” of cleaning in order to help prevent the spread of infections.

IMAGES IN 3D

The 3D images refer to the three key challenges that building managers should manage to help ensure that building users stay healthy, says Optisolve CEO Brad Evans.

According to Evans, 3Ds refer to the following:

DETECT

The first step in keeping users healthy is to locate health-threatening pathogens in the building.

DISINFECT

Once located, these surfaces must first be cleaned and then disinfected.

“As with ATP monitors, imaging technologies cannot determine what pathogens are present,” says Evans. “As a result, ‘broad range’ or ‘broad spectrum’ disinfectants that kill a variety of pathogens should always be used.”

DISCUSS

For example, if pathogens are located on one window ledge, this information must be discussed and shared with administrators and all cleaning professionals in the facility.

“Unfortunately, when imaging technologies point out a potentially contaminated surface, administrators and cleaning professionals often believe the problem is confined to that specific area” says Evans. “In many cases, however, if one specific area is contaminated, we find the same problem in similar areas throughout the facility.”

To clean or to disinfect? a simple definition.

Gaétan Lanthier

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 a real definition.

Deteriorated surfaces definition

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.

surfaces-vetustes definition

Safe surfaces definition

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 !

corridor-hopital-lalema definition

Disinfected surfaces definition

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.
