What class of work includes janitorial tasks that may disturb asbestos?

The class of work that includes janitorial tasks that may disturb asbestos is classified as Class IV. This designation specifically addresses work activities that are related to housekeeping or maintenance tasks that could potentially interfere with asbestos-containing materials. Janitorial tasks may involve sweeping, mopping, or cleaning surfaces where asbestos might be present, thus raising the risk of fiber release.

Class IV work does not require any specialized handling procedures for asbestos, but workers must still be aware of the presence of asbestos and take necessary precautions to minimize exposure. This contrasts with other classes of work, such as Class I, which involves the removal of asbestos insulation, and Class II, which pertains to the removal of other types of asbestos-containing materials that do not create a high risk of fiber release. Class III deals with repair and maintenance activities that could disturb asbestos-containing materials, which is more intensive than what typical janitorial tasks might involve. Therefore, Class IV is the appropriate classification for work involving janitorial tasks where there is potential disturbance of asbestos.
