  • OSH Answers: Safety Hazards. Canadian Centre for Occupational Health and Safety (CCOHS). Information on safety hazards in the OSH Answers site will apply mostly to the physical conditions of the workplace or the way equipment and machinery are used. Safety hazards in this section will deal with machine guarding, and mechanical power transmission systems.
