Exposure to hazardous substances on construction sites presents serious risks to worker health and safety. OSHA regulations are designed to minimize these risks through requirements for proper hazard communication, exposure control, ventilation, and safe handling of toxic chemicals. These standards are critical for effective industrial hygiene practices in the construction industry.
