EHS stands for Environmental Health and Safety, a generalized reference to the laws and regulations designed to protect employees from workplace hazards. EHS programs focus on ensuring compliance with these regulations, protecting the business from legal exposure, and ensuring that all employees follow the company's environmental policies. Many EHS programs focus on the Occupational Safety and Health Administration, or OSHA, a division of the United States Department of Labor that sets and enforces standards with which a company must comply. OSHA provides a variety of training guidelines and resources, and in some cases, employees must obtain OSHA licensing or certification before starting their jobs.
