What does asbestos removal consist of ?

Asbestos abatement is the process of safely removing asbestos from a building or structure. Asbestos is a natural mineral that has been widely used in the construction industry due to its insulating, fire-retardant and corrosion-resistant properties. However, exposure to asbestos has been shown to cause serious health problems, including lung cancer, mesothelioma, and other respiratory diseases.

Asbestos removal generally involves the following steps:

Risk Assessment: Before beginning the asbestos abatement process, a complete assessment of the asbestos-containing materials should be carried out to determine the amount of asbestos present, its location and its condition.
Planning: An asbestos abatement plan is developed, detailing the specific methods that will be used to safely remove the asbestos. This plan must comply with local and national safety regulations

About asbestos

Preparation: The area where the asbestos will be removed is prepared by tightly sealing the area to prevent the spread of asbestos fibers into the air. Workers wear appropriate personal protective equipment (PPE).
Removal: Asbestos-containing materials are carefully removed, taking care not to damage them further to minimize the release of asbestos fibers.
Disposal: Waste containing asbestos is disposed of safely and in accordance with current environmental regulations. They are usually sealed in special bags and transported to an approved disposal site.

Cleaning: The area is thoroughly cleaned to remove all traces of asbestos.
Verification: Air tests and visual inspections are performed to ensure asbestos has been completely removed and the area is safe.
Report: An asbestos abatement report is written to document all stages of the process and ensure that everything has been carried out in accordance with safety standards.
Asbestos removal is a highly regulated operation in many countries due to the health risks associated with asbestos. It must be performed by qualified and certified professionals who are trained to safely handle this hazardous material. Asbestos is harmless if left undisturbed, and asbestos fibers only become dangerous when handled.

All about asbestos decontamination and asbestos removal

Asbestos abatement procedure: The very first step is to take samples from the items affected by the renovations. They are then analyzed in an independent laboratory to find out whether the materials are contaminated with asbestos or not.

The investment of analysis of the different surfaces likely to contain asbestos is essential, because it could allow you to save on the asbestos removal installations and procedures to be planned. Once the contaminated area has been identified, our team of specialists will carry out the decontamination work meticulously, equipped with the necessary equipment according to the assessed risk levels: low, medium and high.

The higher the level of risk, the greater our facilities and precautions. It is no longer a simple standard filter mask, but the establishment of temporary airtight changing rooms with or without a shower (depending on the risk). Regardless of the level of risk your project faces, your contractor and the experts involved will be able to inform you of the various options available to you at the appropriate time.

Testing of materials that may contain asbestos

Regardless of the level of risk your project faces, your contractor and the relevant experts will be able to inform you of the different options available to you at the appropriate time.

In floor slabs, asbestos is used primarily for its insulating properties and its ability to resist heat and fire. In addition to the slabs, the putty injected between the slabs could also contain them.

Sprayed textured ceilings were popular from the 1930s through the 1980s because they were an easy way for builders to hide imperfections.

In a house built between 1930 and 1950 that has not been renovated, there is a 50% chance of having asbestos in the walls.

Decontamination work: Asbestos removal procedure in 6 steps

Removing asbestos from your home is not as simple as it seems, due to the dangers associated with this material. It is important to undertake such a project correctly and safely to ensure the safety of yourself and those around you during the process.

Asbestos decontamination work can be divided into several stages. Here is a simplified version in 6 steps:

Material Sampling and Analysis: The material sampling and analysis step is crucial in the asbestos decontamination process. It aims to determine the presence of asbestos, determine the concentration, and identify the types of asbestos in materials.
Installation of containment zones and negative pressure: The installation of decontamination zones consists of hermetically closing the areas where the work is to be carried out using polyethylene containment canvases. Negative pressure machines equipped with high efficiency HEPA filters are installed to continuously filter the air during the execution of the work.
Demolition and removal of contaminated materials: Materials containing asbestos are removed completely. Asbestos debris is placed in sealed and lined bags for safe transport to an appropriate drop-off point.
Cleaning and encapsulation: At the end of the work, a complete cleaning using HEPA certified equipment is carried out. The work area is carefully cleaned and inspected to ensure complete elimination of dust. Once cleaning is complete, we can proceed to encapsulate the area which involves applying a sealing agent to all surfaces.
Final Air Test: Perform air quality tests to ensure the area has been properly decontaminated and asbestos fiber levels are within safety standards.
Reporting and Documentations: Full documentation of all work performed, including test results, decontamination certifications, and any other documents required by local regulations.

It is essential to emphasize that this work must be carried out by trained and certified professionals, and in accordance with current regulations to guarantee the safety of all those involved.

In addition to the 2 containment methods, there are also 2 asbestos removal methods, there are wet and dry works:

Wet asbestos removal works:

Is a method where water is used to suppress dust, making it easier to contain. This process generally requires more time for decontamination, since the surfaces must be cleaned several times.

Workers should avoid dry sweeping or shoveling asbestos debris, as this can create hazardous fibers that can become airborne and pose a risk to human health.

Asbestos removal requires the greatest precautions, in particular the use of negative air machines, connected to HEPA filters which eliminate dangerous particles. These machines can be placed around the perimeter of sites where there is asbestos to prevent it from spreading into areas open to the public, such as sidewalks or roads adjacent to buildings being renovated. Negative air machines are essential equipment for working with materials containing asbestos.

Dry asbestos removal works:

Dry asbestos removal work consists of removing contaminated materials and ensuring that they are well sealed. It could also involve using a HEPA filter vacuum cleaner for asbestos. This method should only be used if wet decontamination presents an electrical hazard.

Only qualified experts have the knowledge and skills to properly decontaminate asbestos using either of these methods.

How is an asbestos decontamination airlock made up?

A double-compartment changing room is often used to help workers clean themselves properly after working on a contaminated site. A double compartment locker room (SAS) requires two sets of locker rooms separated by showers. Using a dual-compartment locker room allows workers to remove contaminated clothing in one compartment, wash off asbestos contaminants in the shower, and use the second locker room to store their regular street clothes.

An asbestos decontamination airlock is a structure designed to allow workers to safely leave an area contaminated by asbestos while preventing the spread of asbestos fibers outside. Here is how it is generally made up:

Un SAS de décontamination d’amiante est une structure conçue pour permettre aux travailleurs de quitter en toute sécurité une zone contaminée par l’amiante tout en évitant la propagation de fibres d’amiante à l’extérieur. Voici comment il est généralement constitué :

Physical structure: The SAS is generally a temporary structure built near the contaminated work area. It is generally made of reinforced plastic panels or sheeting to prevent the escape of asbestos fibers.
Dirty Entrance: This area is where workers enter from the asbestos contaminated area. They wear their protective clothing here. There may be an access hatch to this area where workers equip themselves with disposable coveralls, respiratory masks, gloves and other personal protective equipment.
Undressing area: This is where workers remove their contaminated protective clothing. Coveralls and other personal protective equipment are usually thrown away in special asbestos bags.
Shower: There may be a shower in the SAS to allow workers to wash their bodies to remove any remaining asbestos dust on their skin.

Clean Entrance: Once workers are completely decontaminated, they can enter the clean zone from this area. This is where they dress in clean clothing and remove their personal protective equipment cleanly.
Strict procedures: It is essential to have strict procedures for entry and exit from the SAS, including the designation of personnel responsible for overseeing the process.
Ventilation system: The SAS must be equipped with a ventilation system to ensure that contaminated air is captured and filtered before being released outside.
Worker Training: All workers using the SAS must be properly trained in decontamination procedures and the use of personal protective equipment.
Safety instructions: Appropriate safety instructions and warnings must be posted in the SAS to remind workers to follow procedures.

It is essential to note that the design and use of an asbestos decontamination airlock must comply with local asbestos safety standards and regulations, as these can vary from region to region. other. Worker safety and preventing the spread of asbestos are top priorities in such situations.

There are 3 categories of risks depending on the friability of the materials:

Low Risk Work :

The sites where low-risk asbestos removal work is carried out involve tasks that can produce very low exposure to asbestos dust. The installation, handling or removal of manufactured equipment containing asbestos provided that they are and remain in a non-friable state. (Does not produce or produce little dust) In the event of sawing, cutting, profiling or drilling of materials containing asbestos, the work must be carried out using electric tools equipped with a system of suction equipped with HEPA filter.

When low-risk asbestos decontamination work is carried out, the necessary protection for workers carrying out asbestos decontamination is a mask that covers at least the mouth and nose. They must be equipped with a HEPA filter, which will protect their lungs from volatile matter in the air.

Moderate risk work :

Sites where moderate-risk work is carried out involve tasks that can produce significant exposure to asbestos dust. For example, the total or partial removal of false ceilings, the removal of friable materials containing asbestos, the handling or removal of small quantities of friable materials containing asbestos whose volume does not exceed 0 .03 m3 and any other work likely to emit dust.

The team will always have to be protected in the event of asbestos decontamination. The higher the risks, the higher the level of protection should be. In the case of moderate-risk work, workers must wear protective clothing, as well as a protective mask that covers the nose and mouth with HEPA filter cartridges.

High risk work :

Work sites where high-risk decontamination work is carried out involve tasks that can produce major exposure to asbestos dust. The total or partial demolition or stripping of a building whose walls are made of plaster containing asbestos, the repair, modification, demolition of furnaces, boilers or other structures built in whole or in part of refractory materials containing asbestos.

In the case of high-risk work, a decontamination airlock equipped with showers must be installed in the work area.

In the case of high-risk work, it is essential to properly protect personnel and the environment. In addition, it is necessary to wear a mask with an assisted ventilation system and a high-efficiency HEPA filter, in addition to protective clothing that covers the whole body.

For more information, consult the CNESST sheet.

Protection of responders and personal protective equipment

Personal protective equipment (PPE) is the clothing and equipment worn to protect against hazards in the workplace.

Workers exposed to asbestos dust are required to wear special respiratory protection known as a half-mask air-purifying respirator. This type of respirator is capable of reducing exposure to asbestos by 99.99% thanks to the filtration system designed for asbestos fibers. The worker is not exposed to asbestos fibers since they do not reach the inside of the mask.

Protective clothing and equipment, such as gloves and eye protection, should also be worn to help protect the asbestos worker from the dangers of exposure.

Workers performing asbestos removal work described as high or moderate risk must use a respirator with a full facepiece covering the entire face.

Asbestos work involves the removal of asbestos-containing materials, namely asbestos cement, corrugated asbestos cement, non-friable asbestos lagging, asbestos boards or insulation boards in asbestos, if the quantity of asbestos removed is likely to exceed 2 square meters in a single day or 10 square meters per week.

For example Asbestos removal activities may include :

the removal of asbestos and asbestos-containing materials from anarticle or structure;
removal of asbestos cement sheets.

The Dangers of Asbestos

Asbestos is a natural mineral composed of microscopic fibers that are resistant to heat, fire and many chemicals. However, exposure to asbestos is associated with several types of cancer, mainly due to inhaling its fibers. The main cancers caused by asbestos include:

Lung cancer: The average time from exposure to the onset of cancer is 20 to 30 years. Although lung cancer is generally associated with long-term exposures, studies indicate that workers exposed for one to twelve months were at increased risk of developing lung cancer years later.

Mesothelioma (cancer of the pleura): Mesothelioma is relatively rare in the general population, but it is often seen in workers and sometimes in their family members or people living with them.
Asbestosis: Asbestosis is a chronic lung disease characterized by the formation of scar-like tissue in the lungs. This fibrosis reduces the elasticity of the lungs, making it more difficult to breathe. Shortness of breath is the most common symptom. In most cases, one of the physical signs is the presence of crepitations, which can be heard using a stethoscope
Laryngeal cancer: Exposure to asbestos has also been linked to an increased risk of laryngeal cancer.

Pleural plaques: Pleural plaques are benign fibrous deposits on the pleura caused by exposure. They do not have the potential for malignant degeneration, but are an exposure marker indicating a risk of developing other diseases.
Ovarian cancer: There is limited evidence, but some cases of ovarian cancer have been associated with asbestos exposure, particularly among women working in asbestos-exposed industries.

Workers performing work on Class A asbestos should use respiratory protection specifically designed for asbestos, such as a half-mask air-supplied respirator. The filter must be asbestos specific and contain glass fibers or be high efficiency (95%)

the stripping, scraping or cutting of an asbestos coating.

Workers performing asbestos removal work described as Class B or C must use an air-fed respirator with an assigned protection factor of at least 500.

Class B asbestos removal work involves the removal of materials containing asbestos, namely asbestos cement lagging and asbestos insulation boards, if the amount of asbestos removed is likely to exceed 10 square meters in a single day or 30 square meters in a week.

For example, asbestos removal activities may include :

removal of asbestos sheets from boilers
asbestos cement roof removal

Class C asbestos work is the disturbance of asbestos insulation panels on beams, joists, lagging and supports if more than 10m² is removed in a day or week.

For example, asbestos removal activities may include

the removal of the asbestos insulation from the partitions;
the stripping, scraping or cutting of asbestos insulation boards attached to steel beams and joists.

All asbestos workers must wear protective clothing while working on asbestos. The type of clothing will depend on the asbestos classification assigned to the work performed.

Canadian regulations on asbestos removal

Asbestos removal regulations in Canada state that asbestos or a product containing asbestos cannot be disposed of in a landfill, waste disposal site or incinerator. Asbestos must be taken to a transfer station accredited by the Ministry of Environment and Climate Change.

Asbestos waste is considered hazardous material due to its toxic nature. Once asbestos waste has been removed from a building or structure, asbestos disposal regulations must be followed to ensure that the asbestos waste does not pose a health hazard. health.

The asbestos removal process begins with consulting an asbestos removal professional who will examine the area where the asbestos is present to determine if it would be safe to remove the material from asbestos. If the asbestos is in an easily accessible location and can be safely removed, it is possible for a homeowner to remove it. If the asbestos cannot be removed easily, it is recommended to hire a specialist asbestos removal contractor, as the regulations in this area state that asbestos waste should only be removed by professionals.

Asbestos waste handling

At the transfer station, asbestos waste is handled with care and responsibility. Asbestos waste must remain wet at all times so as not to produce dust or dry out.

When asbestos is removed from a building or structure, it should be double bagged for security. The asbestos will be weighed before being placed in the truck to determine its total asbestos weight. This information will be entered into an Asbestos Removal Report, which must remain with the asbestos material at all times. When the asbestos disposal rules are complied with, the asbestos waste will be disposed of in an asbestos landfill at a chargeable facility. Asbestos materials will be buried or covered with earth to protect the asbestos from exposure.

Asbestos removal costs

The cost of asbestos remediation can vary significantly depending on several factors, including the size of the contaminated area, the type of asbestos-containing material, the level of contamination, geographic location, local regulations.

Here are some elements that can influence the cost:

Extent of contamination: The larger the contaminated area, the higher the costs.
Type of asbestos-containing material: Some materials are more difficult to handle and remove than others, which can influence costs.
Level of contamination: If contamination is severe, additional safety measures may be necessary, which can increase costs.
Geographic Location: Costs may vary depending on region, labor costs and local regulatory standards.
Local Regulations: Local regulatory requirements may influence decontamination methods and associated costs.

F.A.Q.

Frequently asked questions about asbestos

When is asbestos dangerous?

Asbestos is very harmful when it is present in the form of dust, invisible to the naked eye, floating in the surrounding air, so asbestos fibers can be breathed in.

Is it dangerous to live in a house with asbestos?

Asbestos poses a health hazard when asbestos fibers are stirred up into the air. In other words, asbestos poses a health risk only when fibers are suspended in the air and people breathe them in.

Who can do asbestos removal?

Only a certified company should perform asbestos decontamination work. Asbestos removal work requires a lot of precautions before and during the work. If the work is not carried out according to the standards in force, this can become a real problem for the occupants. This is why we always recommend doing business with experts.

Where is the asbestos disposed of at the end of the work?

At the end of the day or at the end of the asbestos removal work, the asbestos-contaminated debris is transported to a site where the materials will be taken care of and handled according to safety standards.
