The U.S. Occupational Safety and Health Administration (OSHA) has launched a new national emphasis program (NEP) to help prevent heat-related illnesses at outdoor and indoor workplaces, including electrical contractors and other wiring installation contractors (2017 NAICS Code 2382).
The program, CPL 03-00-024, entitled “Outdoor and Indoor Heat-Related Hazards,” was announced by Labor Secretary Marty Walsh with Vice President Kamala Harris at a union training center in Philadelphia.
The most important part of the program is that it targets specific industries and activities, such as working outdoors in areas announced by the National Weather Service to be undergoing a heat wave, or working indoors near radiant heat sources, such as foundries.
Changes in Inspection Procedures
Under the program, OSHA will conduct, in certain outdoor and indoor workplaces, programmed inspections on any day for which the National Weather Service (NWS) has announced a heat warning or advisory in the local area. Those workplaces include the high-hazard industries named in Appendix A to the program, including electrical contracting and other industries in which IEC members operate.
The NWS issues a heat advisory within 12 hours of the onset of extremely dangerous heat. The general rule of thumb for this advisory is that the maximum heat index is expected to be 100°F or higher for at least two days, and nighttime air temperatures will not drop below 75°F.
Even if an employer is not covered by the NEP because it is not in the listed high-hazard industries, it could still face an inspection under the NEP. It requires OSHA inspectors conducting an investigation or inspection not related to heat hazards to open a heat-related inspection if a hazardous heat condition is recorded in an OSHA 300 log or 301 incident report, or if an employee brings a heat-related hazard to the inspector’s attention. The program also will require inspectors to ask during non-heat inspections whether the employer has a heat-related hazard prevention program that applies when the heat index for the day is expected to be 80°F or more. The NEP requires each OSHA regional office to double its number of heat-related inspections.
For example, an inspection following a hospitalization for an arc flash injury in March in Tampa, FL, would probably expand into a heat-related inspection based just on the heat index. More on that figure below.
What OSHA Will Be Doing During a Heat-Related Inspection
During heat-related inspections, the program requires OSHA compliance safety and health officers (CSHOs) to:
- Review OSHA 300 logs and 301 incident reports for evidence of heat-related illnesses
- Review records of heat-related emergency room visits or ambulance transport
- Interview workers for symptoms of headache, dizziness, fainting, dehydration, or other indicia of heat-related illnesses
- Document the existence of conditions, such as high temperature, that cause the heat-related hazards
- Determine whether the employer has a heat illness and injury program, including whether:
– The employer has a written program
– The employer monitors temperature and worker exertion
– There is unlimited cool water easily accessible to workers
– There are required hydration breaks
– There are scheduled rest breaks
– Workers have access to a shaded area
– New and returning workers are provided time for acclimatization
– A “buddy” system is in place on hot days
– Work is scheduled to avoid hot parts of the day
– Job rotation is used to limit heat exposures
– Employees are trained in the importance of hydration, heat illness signs, first aid and summoning of emergency personnel
An interesting aspect of the directive is its reference to the legends and heat index ranges used by the National Weather Service’s heat index chart—Caution (80°F– 90°F HI), Extreme Caution (91°F – 103°F HI), Danger (103°F – 124°F HI), and Extreme Danger (126°F or higher HI). OSHA knows, after the scientific bases for these legends and ranges were questioned, its attorneys declined to rely on them, and that an administrative law judge of the Occupational Safety and Health Review Commission (in a case handled by this firm) found that they lacked a scientific basis.
Next Rulemaking Steps for OSHA
Although the NEP is not an OSHA standard, the agency has announced it is working on a proposed standard. There is no reliable way to know when OSHA will publish a proposed standard. OSHA will probably try to publish one in time to permit a final standard to be issued before the Biden Administration ends, but that is a guess. To do that, the final standard will probably follow the California model (the Assistant Secretary of Labor for OSHA, Doug Parker, is formerly the head of California’s OSHA State Plan), which requires training, cool drinking water, five-minute cool downs in shade, supervisor monitoring, a heat illness prevention program, and high-heat measures.
What Contractors Should Consider Doing Now
IEC contractor members – especially in warmer climates – may want to consider reviewing:
- Policy – Review and update (or create?) a written heat illness and injury program; consider using a post-offer medical questionnaire that includes questions about conditions or medications that heat exposure may exacerbate.
- Training – Train employees on recognizing symptoms and supervisors on entire program and how to handle emergencies.
- Compliance – Monitor heat exposure projections and compliance with the program.
- Enforcement – Take action when the program is not followed.
These actions will help keep workers safe from heat-related illnesses and injuries and avoid or minimize any OSHA inspections or citations.
