Asbestos fibers may be released into the air by the disturbance of asbestos-containing material during product use, demolition work, building or home maintenance, repair, and remodeling. In general, exposure may occur only when the asbestos-containing material is disturbed or damaged in some way to release particles and fibers into the air.

Mold is a type of microscopic fungus that grows in multicellular filaments called hyphae and reproduces by releasing airborne spores. It thrives in damp, warm, and humid environments. Removing mold is important to reduce toxic spores and potential health concerns.
