Standard of exposure to asbestos in Quebec

• The standard for occupational exposure to asbestos in Quebec is the same since 1990. The value-weighted average exposure (TWA) and the short-term exposure value (STEV) for chrysotile, tremolite, anthophyllite and actinolite are 1 fiber / ml (f / ml) and 5 f / ml. The TWA and STEL for crocidolite and amosite are 0.2 f / ml and 1 f / ml.
• The standard of 1 f / ml is ten times higher than the prevailing standard in Ontario, the United States and France, where it is 0.1 f / ml.
• The standard of 1 f / ml is 100 times higher than the norm in the Netherlands and Switzerland.
• In France, Decree No. 2012-639, which came into force in July 2012, states that the current standard for occupational exposure to asbestos of 0.1 f / ml decrease to 0.01 f / ml from July 2015.
• There is no environmental standard for exposure to asbestos.
