OSHA to Initiate Heat Illness Safety Rule

Posted on 12/6/2021 by Lauren Scott and Roseanne Bottone

Update (12/6/2021)

OSHA is extending the period for submitting comments on the Advance Notice of Proposed Rulemaking (ANPRM) for Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings. Comments on the ANPRM must now be submitted by January 26, 2022.

The 30-day extension provides stakeholders more time to review the ANPRM and collect information and data necessary for comment.

Update (10/26/2021)

OSHA announced an Advance Notice of Proposed Rulemaking (ANPRM) on October 26 to protect indoor and outdoor workers from hazardous heat. The Agency will begin by gathering diverse perspectives and expertise on topics, such as heat-stress thresholds, heat-acclimatization planning and exposure monitoring.

Starting October 27, industry stakeholders can submit comments at, the Federal e-Rulemaking Portal and refer to Docket No. OSHA-2021-0009. All comments must be submitted by December 27, 2021.

Original Article Text (10/4/2021)

OSHA is expected to introduce a potential occupational heat exposure safety rule this month as part of a series of immediate enforcement actions to protect workers from heat hazards.

OSHA’s comprehensive initiative on occupational heat exposure, announced September 20, features a series of rulemakings, initiatives, inspections, and committee expansions. The memo requires OSHA to take the following measures:
  • Publish an Advance Notice of Proposed Rulemaking (ANPRM) on heat illness prevention in outdoor and indoor work settings. The ANPRM will be published in the Federal Register in October, followed by public comments. 
  • Implement an enforcement initiative to prioritize heat-related interventions and workplace inspections on days when the heat index exceeds 80°F.
  • Develop and formalize a National Emphasis Program (NEP) on heat inspections—especially in high-risk industries.
  • Form a “Heat Illness Prevention Work Group” within the National Advisory Committee on Occupational Safety and Health (NACOSH).

Why Worry About Heat in October?

The White House memo specifically cites the June 2021 heat wave in the Pacific Northwest, when states reported hundreds of excess deaths and thousands of emergency room visits for heat-related illness.

This is just one of many instances in recent years. The U.S. Department of Labor’s Bureau of Labor Statistics (BLS) reports that from 2011 to 2019, environmental heat cases resulted in an average of 38 fatalities per year and an average of 2,700 cases involving days away from work.

In 2019, one of the largest delivery companies in the world was fined $13,260 for allegedly exposing one of its drivers to excessive heat, requiring immediate medical care. In its citation, OSHA listed the incident as a serious violation.

Although outdoor workers, such as agricultural, construction, and delivery workers, may not be as active in the fall and winter, indoor workers continue to battle heat-related hazards all year round. Workers in industrial kitchens, on manufacturing floors, and in warehouses are all likely to see occupational changes as soon as OSHA implements these measures.
