Part 2: Asbestos during indoor demolition – how to stop the spread with containment, airlocks and the right equipment

During demolition and remediation, asbestos is still one of the most serious risks. This is because there is a risk of releasing fibers and spreading them further in the building – which in turn means that they can affect more than just the person doing the work.

Therefore, it is crucial to work systematically, and the key to a safe working method is the following:

Containment + controlled airflow + clear routines

Swedish Work Environment Authority (Arbetsmiljöverket): write handling and protection instructions

When working with asbestos, it is not only the equipment that is important. Routines and instructions must be clear and adapted to the object.

The Swedish Work Environment Authority emphasizes that employers who will work with asbestos-containing materials must write handling and protection instructions that are adapted to the work in question

Containment and airlocks – crucial for indoor demolition

When performing indoor demolition work, access to the decontamination zone must be via an airlock, and it must consist of 2–3 steps. This is crucial for reducing the risk of fibers being carried out of the zone.

The Swedish Work Environment Authority also describes how the airlock steps work, for example:

• there must be an opportunity to vacuum the protective overalls before taking them off

• in one step you must be able to handle respiratory protection and wash yourself

• in another step you must put on/take off the protective overalls

Why correct dust management matters

Even when working with containment, it is crucial to keep the surfaces clean and reduce the amount of particles in the zone.

This is where the combination of:

• construction vacuum cleaner

• accessories that seal tightly

• air purifier/fan unit

• dust protection tube/shielding

…can help create a more controlled work environment in practice

FAQ

Why do you need a lock when removing asbestos indoors?
To minimize the risk of asbestos fibers being carried out of the decontamination zone. The Swedish Work Environment Authority states that the decontamination zone should be reached via a lock and that it should consist of 2–3 steps.

Do you need instructions when working with asbestos?
Yes. The Swedish Work Environment Authority emphasizes that employers should write handling and safety instructions adapted to the work.

Can asbestos be spread to other rooms?
Yes, fibers can be spread via air currents, clothing and movement if the work zone is not demarcated and controlled.
