The heat is on at OSHA: From NEP to proposed rule
If our article last month about OSHA’s Heat National Emphasis Program (NEP) piqued your curiosity, this one will certainly heat things up! As expected, OSHA has stepped into new territory with a groundbreaking move — proposing a first-ever national heat rule aimed to protect workers from heat-related fatalities and illnesses.

On July 1, the Office of Management and Budget (OMB) completed its review of OSHA’s proposed heat illness prevention rule. The next rulemaking step is publication in the Federal Register, at which time OSHA will open the 120-day public comment period.
Who will be impacted?
OSHA’s proposed rule would apply to all employers conducting outdoor and indoor work in all general industry, construction, maritime, and agricultural sectors under the agency’s jurisdiction.
What can be expected?
Key elements in OSHA’s proposed rule include:
- Heat hazard assessments — evaluating risks for potential heat exposure during certain activities or tasks, especially during extreme temperatures.
- Heat Illness Prevention Plan (HIPP) — creating a plan using input from managers and non-managers aimed at preventing heat-related illness or injury. Written plans would be required for employers with more than 10 employees. All plans must include site-specific evaluation of heat hazards and control methods for heat exposures, be made available to workers in a language they understand, and be evaluated annually for effectiveness.
- Heat Safety Coordinator — designating and authorizing one or more individuals to implement the HIPP and monitor no more than 20 employees on a shift for signs and symptoms of heat-related illness.
- Monitoring and communication — providing hazard alerts to employers prior to shifts during elevated temperatures and identifying heat hazards and monitoring systems (monitoring devices, buddy system, two-way communication, lone worker procedures, etc.) to ensure employee protection from extreme heat and humidity.
- Water – Rest – Shade — providing drinking water and cool or shaded rest areas when temperatures reach 80 degrees. Additionally, once heat triggers reach 90 degrees, employers would need to provide a mandatory 15-minute rest break every two hours.
- Acclimatization — limiting initially and then gradually increasing working hours for new, returning, temporary, and young workers during extreme temperatures. OSHA proposes a requirement for gradual acclimatization to ensure an employee’s exposure to heat is restricted to no more than 20% of a normal work shift exposure duration on the first day of work, 40% on the second day, 60% of the third day, and 80% on the fourth day with additional protocols for returning workers.
- Training —providing annual and refresher training on identifying heat hazards, personal risk factors, signs and symptoms of heat stress, emergency response, and incident reporting to workers. Additionally, employers would be expected to train supervisors and heat safety coordinators regarding heat monitoring and handling heat emergencies.
- Recordkeeping — storing written or electronic records of monitoring data for at least six months, creating and maintaining incident records, and deploying internal auditing to ensure overall compliance.
What will trigger the rule?
OSHA based the criteria for implementing heat precautions and controls on recognized and accepted standards used by the National Weather Service (NWS) and the National Institute for Occupational Safety and Health (NIOSH) as shown in the chart below.
National Weather Service (NWS) | National Institute for Occupational Safety and Health’s (NIOSH) |
Heat index of 80° Fahrenheit (F) | Wet Bulb Globe Temperature (WBGT) equal to recommended alert limit (RAL) |
Additional requirements triggered at 90° Fahrenheit (F) | Additional requirements triggered at WBGT equal to recommended exposure limit (REL) |
Who is exempted?
The standard would NOT apply to:
- Work activities for which there is no reasonable expectation of exposure at or above the initial heat “trigger ;”
- Short duration employee exposures at or above the initial heat trigger of 15 minutes or less in any 60-minute period;
- Organizations whose primary function is the performance of firefighting, emergency medical services, technical search and rescue, or any emergency response activities already covered under other regulations;
- Work activities performed in indoor work areas or vehicles where air conditioning consistently maintains ambient temperature below 80°F;
- Telework (i.e., work done from home or another remote location of the employee’s choosing); and
- Sedentary work activities at indoor work areas that only involve some combination sitting, occasional standing and walking for brief periods of time, and occasional lifting of objects weighing less than 10 pounds.
Timeline
While OSHA’s Rulemaking Process indicates it can take between 24 and 60 months to analyze the record and develop a final rule, OSHA’s recent focus on a heat standard suggests that this may very well be fast-tracked. So, employers should anticipate publication to the Federal Register some time in the next few months.
The proposed rule indicates that, once adopted, the final rule will take effect within 60 days of its publication in the Federal Register. Employers will be required to comply with all requirements of the final standard within 150 days after publication to the Federal Register.
Keys to remember: OSHA’s proposed Heat Rule is on its way to the Federal Register, and it applies to all employers who oversee outdoor and indoor work within the agency’s jurisdiction. Employers would be expected to implement heat illness prevention measures, like a hazard assessments, written plans, and training, when temperatures reach trigger points. Impacted employers should consider voicing their opinions during the Public Comment period that will follow publication of the proposed rule in the Federal Register.
