The Occupational Safety and Health Administration (OSHA) has issued an Instruction effective April 8, 2022, establishing a National Emphasis Program (NEP) for Outdoor and Indoor Heat-Related Hazards. This program has been implemented pending OSHA's pursuit of a health rule governing indoor and outdoor work which it announced about eight months ago, taking comments through January 26, 2022. Both the Obama and Trump Administrations had rejected a heat rule, but it is being pursued during this Administration. Without a specific heat standard, OSHA applies its general duty clause to cite employers for failing to protect their workers. However, judges have vacated citations in many of those cases because OSHA has not been able to prove the heat threat.
OSHA Assistant Secretary Doug Parker who oversees OSHA suggested that OSHA wants to implement an indoor standard as well as one for outdoor work. Employer representatives have expressed concern that any proposed standard should not require all industries and all locations to abide by the same requirements, and instead argued for an industry-specific standard.
The NEP prioritizes on-site (in-person) response by OSHA to complaints and for all employer-reported hospitalizations related to heat hazards. It cites the National Weather Service (NWS) approach to the heat index as creating a greater concern when it is 80°F or higher, and this index is sometimes referred to the apparent temperature, and measures how hot it really feels when relative humidity is factored in with the actual air temperature.
An on-site inspection will be investigated where an employee brings a heat-related hazard to the attention of OSHA such as being exposed to high temperature conditions without adequate training, acclimatization or access to water, rest and shade. OSHA will also inquire during inspections regarding the existence of any heat-related hazard prevention programs on heat priority days, when the heat index for the day is expected to be 80°F or more.
The NEP lists both indoor and outdoor industries known to have heat-related hazard incidents to be considered targeted industries in terms of unprogrammed inspections. The list includes, among many others, sawmills, furniture manufacturing, various transportation industries including local delivery, warehousing, construction, and agriculture.
During heat-related inspections, OSHA shall:
(a) Review OSHA 300 Logs and 301 Incident Reports for any entries indicating heat-related illness(es);
(b) Interview workers for symptoms of headache, dizziness, fainting, dehydration, or other conditions that may indicate heat-related illnesses, including both new employees and any employees who have recently returned to work;
(c) Determine if the employer has a heat illness and injury program addressing heat exposure, and consider the following:
Is there a written program:
OSHA states it will always verify an employer's assertion regarding workplace conditions or worker exposures to heat by interviewing employee(s) at the site.
