OSHA has updated its National Emphasis Program (NEP) on workplace heat hazards, effective April 10, with a renewed focus on meat-processing plants and other high-risk sectors. The revised directive, which could remain in effect for up to five years, drops previous numerical inspection goals but sharpens enforcement guidelines.
Expanded Target List
The updated NEP now covers 55 industries, including animal slaughtering, cheese manufacturing, bakeries, tortilla production, warehousing, courier services, and waste collection. Notably, fruit and tree nut farming have been removed from the priority list, while greenhouse and floriculture operations were added. This shift reflects OSHA's evolving risk assessment.
Enforcement Without Quotas
OSHA has eliminated its earlier inspection quotas, a move that has drawn criticism from worker advocates. Jocelyn Sherman of the United Farm Workers expressed concerns that without clear targets, proactive inspections at hot worksites may decline. OSHA counters that the updated program is designed to enhance outreach, compliance support, and concentrate enforcement where heat risks are highest.
Data-Driven Approach
Since 2022, federal OSHA has conducted approximately 2,400 heat-related inspections annually, including about 50 fatality probes each year. Bureau of Labor Statistics data cited in the directive show an average of 3,793 heat-related DART cases (days away, restricted, or transferred) and 48 deaths annually from 2021 to 2024. The enforcement threshold remains broad: on heat priority days, compliance officers will widen inspections, and during National Weather Service heat advisories, random inspections will target high-risk industries.
Legal and Regulatory Context
Without a finalized federal heat safety rule, OSHA relies on the General Duty Clause of the Occupational Safety and Health Act, which requires employers to maintain workplaces free from recognized hazards. The agency's rulemaking on a Heat Injury and Illness Prevention standard remains pending, with a public hearing concluded in July 2025 and post-hearing comments accepted until October 30. If adopted, the rule would mandate employer plans for heat risk identification and management.
Legal experts note that the updated NEP elevates heat hazards to a "core enforcement priority," signaling tougher, data-driven enforcement and clearer citation guidelines. Employers in targeted sectors, especially meat processors, can expect increased documentation checks on water access, rest breaks, shade, worker training, acclimatization, and heat monitoring.
Broader Implications
While the NEP trims its focus by removing 46 industries and adding 22, companies not on the list are not exempt. A single worker complaint, hospitalization, or fatality can trigger an inspection. State-level regulations add complexity, with California, Oregon, Washington, Colorado, Maryland, Minnesota, and Nevada already enforcing some form of heat-related standards.
The timing is critical as summer approaches, and many employers across food processing, warehousing, construction, and agriculture continue operating without a finalized federal heat rule. The updated NEP represents OSHA's latest effort to crack down on heat hazards, particularly in indoor operations like meat processing where risks are significant.
