Part 4 Chemical Hazards, Biological Hazards and Harmful Substances

Section 32 Prohibitions related to asbestos

Crocidolite asbestos may not be used in existing and new buildings. Where crocidolite is found in an existing building, it must be removed unless removal poses a greater hazard to workers. If removal is not possible or reasonably practicable and workers will not be exposed to crocidolite in the course of their usual work procedures, the implementation of a management plan may be acceptable. The employer must document the conditions and rationale to explain why the crocidolite cannot be removed. The management plan should include the elements outlined in Chapter 4 of the Alberta Asbestos Abatement Manual. If the building is to be renovated or demolished at a later date, the crocidolite will have to be removed at that time.

To prevent asbestos fibres from becoming airborne and then being inhaled by workers or contaminating a work site, the spray application of materials containing asbestos is prohibited. This is because of the hazards associated with spray application of asbestos products and also because these types of products tend to be friable i.e. easily crumbled with hand pressure. Friable asbestos poses a greater hazard since there is a greater potential of the product releasing fibres.
