Each state manages heat injury and illness prevention differently. Use the chart below to determine if additional requirements apply to your operations.
Federal OSHA doesn't currently have a heat injury and illness prevention standard but recognizes the need for one. OSHA would cite the General Duty Clause.
Though not regulations or mandates, OSHA has National Emphasis Programs (NEPs) that focus on major health and/or safety hazards which are of recognized national significance. They provide guidance to the OSHA field offices for program planning and for conducting inspections. Employers wanting to ensure compliance and prepare for potential inspections should refer to the National Emphasis Program - Outdoor and Indoor Heat-Related Hazards (osha.gov).
Federal regulatory citation
29 USC 654 - Duties of employers and employees
OSHA permits states to assume the enforcement responsibility for occupational safety and health issues by adopting a state plan. At a minimum, state plans must be as stringent as OSHA protections, rules, and regulations.
