Hazardous work refers to jobs that pose significant risks to the health and safety of workers. This can include tasks that involve exposure to harmful substances, dangerous machinery, or extreme environmental conditions. Examples of hazardous work environments include construction sites, factories, and chemical plants, where safety measures are crucial to prevent accidents and injuries. Workers in hazardous jobs may face risks such as falls, chemical burns, or respiratory issues. To mitigate these dangers, employers are required to provide proper training, safety equipment, and protocols. Organizations like the Occupational Safety and Health Administration (OSHA) set regulations to ensure safer working conditions in these environments.
