Without proper handling, storage, use, and disposal of construction materials serious injuries and illnesses can occur. Where safe work practices are not followed injuries, including death, can result from being crushed-by or caught in between materials and equipment. Additionally, the use of construction materials and the generation of waste require proper management through good housekeeping practices and proper disposal. Injuries that are often attributed to poor housekeeping and disposal management include trips and falls and exposure to hazardous chemicals.
