OSHA Updates Heat-Related Hazards NEP
OSHA’s revised National Emphasis Program (NEP) for Outdoor and Indoor Heat-Related Hazards reinforces the need for practical heat-safety controls in workplaces where employees may be exposed to high heat. The program focuses on prevention through clear requirements for water, rest, shade or cooling areas, acclimatization, training, monitoring, and emergency response.
Program Overview
Effective Date & Duration: The revised directive took effect April 10, 2026, and remains in place for five years.
Scope: Applies to outdoor and indoor heat-related hazards in general industry, construction, maritime, and agriculture.
When Heat Hazards Are Reviewed: Heat conditions may be reviewed during heat advisories or warnings, when heat hazards are observed, or when complaints, referrals, or heat-related incidents occur.
Legal Basis: Until a final federal heat standard is issued, OSHA continues to address recognized heat hazards under the OSHA General Duty Clause.
Heat Safety Requirements
Water: Provide cool, potable drinking water close to the work area and encourage frequent hydration before workers feel thirsty.
Rest and Cooling Areas: Provide required rest breaks and access to shaded, air-conditioned, or otherwise cool recovery areas.
Acclimatization: Gradually increase heat exposure for new workers and for workers returning after time away from hot conditions.
Training: Train workers and supervisors to recognize heat illness symptoms, prevent heat stress, administer first aid, and follow emergency response procedures.
Monitoring: Observe workers for signs of heat stress, especially during high heat, heavy physical work, use of personal protective equipment, or the first days of heat exposure.
