Asbestos decontamination in Montreal

Decontamination of tools used for asbestos decontamination

1. Dirty asbestos decontamination zone

Closest to the asbestos removal area to vacuum and wipe contaminated surfaces and clothing, to store contaminated shoes, to dispose of personal protective equipment in labeled bags and to shower.

2. Clean asbestos decontamination zone

For the storage of clean respiratory protective equipment.

3. A clean change zone

It is important that decontamination areas are physically separated to minimize cross-contamination.

In addition, it is also important that the airflow through these areas always goes to the asbestos removal area and that all contaminated water is collected and disposed of with the asbestos waste. Use caution when moving labeled and sealed bags containing contaminated clothing and wipes from the dirty area through clean areas.

All asbestos waste, including labelled or sealed bags, must be disposed of appropriately and responsibly to avoid any further asbestos-related problems.

Types of asbestos decontamination

You should never attempt to decontaminate yourself, as asbestos treatment is a tedious project that requires the expertise of a professional. So if you have any doubts about the presence of asbestos in your home, it is strongly recommended to contact an expert in order to obtain proper identification and proceed with the removal.

Decontamination can be done in two ways:

1. Wet decontamination

Wet decontamination (or “wet wiping”) involves using disposable rags to wipe contaminated surfaces and objects. If a bucket of water is used, the cloths should not be re-soiled in the bucket as this will contaminate the water, making it asbestos waste. All rags must then be disposed of with asbestos-contaminated waste.

2. Dry decontamination

Dry decontamination involves rolling/folding contaminated leaves and making sure they are properly sealed. This could also involve the use of a specialized vacuum cleaner for asbestos. This method should only be used if wet decontamination presents a risk due to electricity.

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

Personal decontamination

Whether you have hired a team of experts to do the necessary work or have decided to collaborate with an asbestos removal professional, it is essential to follow the proper self-decontamination procedures. Following the removal of asbestos by the pros, you will have to take the following steps:

Keep your respirator and EPI until all work is completed and the area is fully cleaned.

Before removing any personal protective equipment or shoes, clean them thoroughly with an asbestos vacuum cleaner. Safety shoes must also be wiped with a damp cloth, which must then be discarded along with asbestos waste.

Personal protective equipment and footwear should not be removed until visible dust or asbestos residues have been removed. PPE must be carefully removed and disposed of appropriately with other asbestos waste.

Before removing a breathing apparatus, wash thoroughly and pay special attention to the hands, nails and head. Remove the respirator last and carefully wash the face.

Decontamination of tools used for asbestos decontamination

When all asbestos removal work is complete, the tools must be decontaminated by disassembling them (if any) and wiping them with a damp cloth to remove any visible traces of dust and asbestos residue, or by cleaning them with an asbestos vacuum cleaner.

Sometimes it may be easier to completely dispose of the tools as asbestos waste rather than decontaminate them. If you need to remove tools from the asbestos area for decontamination or move them to another asbestos area, be sure to place them in a double bag and label them properly.

What steps should be taken for successful decontamination?

Once detected, asbestos must be removed as soon as possible, but the work carried out in this context must be carried out in strict compliance with the rules set by the Committee on Standards, Equity, Health and Safety at Work (CNESST). These standards must be controlled and applied by the professional who will intervene in the asbestos removal process.

Provide appropriate protective clothing

A company that deploys its workers on a field for asbestos removal work must provide them with appropriate protective clothing,as they are equally vulnerable to inhalation of asbestos particles. Basically, asbestos removal professionals must wear protection kits consisting of a combination of masks,pair of gloves, safety boots, pair of glasses… In addition, the protective masks to be used in this context must be equipped with a protective system Assisted ventilation, they must be sophisticated enough to allow workers to breathe clean air during work.

Preparing the ground

If the decontamination process is to be carried out over a large area,workers must create an on-site shower to wash certain accessories and bags that will be used to store the particles of unbridled material during the work. Then, an additive must be mixed with water to control the spread of the fibres and prevent them from evaporating into the wild. Protective cloths, protective clothing and portable premises must be discarded after the operation. In addition, avoid drinking, eating and smoking during asbestos decontamination.
