Mould
WorkSafeBC provides guidelines for protecting workers from the hazards of airborne mould.
Generally speaking, surface mould found on non-porous (metal, glass and hard plastics) and semi-porous (wood and concrete) materials can be cleaned and reused. However, porous materials, such as ceiling tiles, wallpaper, insulation, drywall, and carpets with more than a small area of mould contamination, should be removed and discarded.
