Occupational health promotes the physical, mental, and social well-being of workers. It aims to prevent adverse health effects from working conditions through a collaborative approach involving occupational medicine, industrial hygiene, and other fields. Occupational health is important because most workers spend many hours each day in their workplace, which should be safe and healthy environments. Common workplace hazards include dusts, gases, noise, vibration, extreme temperatures, stress, and inadequate conditions. Effective occupational health programs control hazards at their source when possible, maintain exposure records, inform workers and employers of risks, and have active health and safety committees.
