Abstract

Occupational exposure to chemicals occurs mainly through the respiratory and dermal routes. In Québec, skin diseases account for 2.5% of occupational diseases accepted by the CSST. However, there are no exposure value limits for the skin, even though it is a major contact area for liquid, solid or particulate contaminants. Some particles may cause skin irritation or dermatitis.

Chemical protective clothing is used to limit dermal exposure to solid aerosols. However, the levels of performance of such clothing are not standardized to help hygienists select a level of protection based on the potential risk associated with occupational activities.

The purpose of this research is to measure the performance of chemical protective clothing materials in realistic conditions. The researchers will establish an initial correlation between material characteristics, protection and comfort. This will facilitate the selection of protective clothing based on its effectiveness in preventing risks specific to each particle type, while taking worker comfort into account.
