Dear Representative Chu and Representative Grijalva:

We, the undersigned organizations, write to express our support for introduction of the Asuncion Valdivia Heat Illness and Fatality Prevention Act (H.R. 3668), legislation that directs the Occupational Safety and Health Administration (OSHA) to issue a standard on the prevention of excessive heat in the workplace for outdoor and indoor workers. We are part of a nationwide network that is raising awareness around the dangers of the climate crisis on workers, by advocating for occupational heat protections. We appreciate your leadership on this bill, in partnership with House Education and Labor Committee Chairman Bobby Scott.

Heat is the leading weather-related killer, and it is becoming more dangerous as 18 of the last 19 years were the hottest on record.[i] Excessive heat can cause heat stroke and even death if not treated properly. It also exacerbates existing health problems like asthma, kidney failure, and heart disease. Workers in agriculture and construction are at highest risk, but the problem affects all workers exposed to heat, including indoor workers without climate-controlled environments. This threat is projected to intensify with global heating, yet, the U.S. does not have a federal heat stress standard for workers.

The National Institute for Occupational Safety and Health (NIOSH) issued criteria for a heat standard in 1972, updating it in 1986 and 2016. Last summer, more than 130 organizations and former OSHA administrators petitioned OSHA for a heat stress standard that builds upon the NIOSH criteria.[ii] At the time of this bill’s introduction, OSHA has yet to issue a formal response to the petition. Meanwhile, California, Washington, Minnesota and the U.S. military have issued heat protections. Absent a federal standard, OSHA currently polices heat-related injuries and deaths only by enforcing its “catch all” general duty clause that requires employers to provide safe workplaces. Enforcement is scarce and, by definition, reactive rather than preventive. Notably, from 2013 through 2017, California used its heat standard to conduct 50 times more inspections resulting in a heat-related violation than OSHA did nationwide under the general duty clause.[iii]

Protecting workers from heat also has economic benefits. In high heat, people work less effectively due to “diminished ability for physical exertion and for completing mental tasks,” which reduces productivity, increases the risk of accidents, and drives up medical expenses.[iv] The costs of lower labor productivity under rising temperatures is estimated to reach up to $160 billion in lost wages per year in the U.S. by 2090 according to the 2018 National Climate Assessment.[v] These impacts can be mitigated by heat protections. For instance, in 2011 a central Texas municipality implemented a heat illness prevention program for outdoor municipal workers that not only resulted in a significant decrease in heat-related illnesses, but a decrease in worker’s compensation costs by 50% per heat-related illness.[vi]

The Asuncion Valdivia Heat Illness and Fatality Prevention Act is named after a farmworker who died of a heat stroke in 2004, after picking grapes for 10 hours straight in 105-degree temperatures. Unfortunately, Mr. Valdivia’s story is not unique, and yet heat-related fatalities, injuries and illnesses are completely preventable. This bill will direct OSHA to develop a heat stress standard for indoor and outdoor workers to prevent further heat-related tragedies. Specifically, it will require employers to develop a heat-illness prevention plan that includes the following commonsense requirements:

  • Develop and implement the standard with meaningful participation of covered employees, and their representatives when applicable, and tailor it to the specific hazards of the workplace;
  • Ensure it is written in a language understood by the majority of the employees;
  • Require that workers who are exposed to high heat have paid breaks in cool environments, access to water for hydration, and include limitations on how long workers can be in extreme heat areas;
  • Create emergency response procedures for employees suffering from heat illness;
  • Provide training for employers and employees on heat stress illness and prevention;
  • Include acclimatization plans to ensure workers can adjust to their working conditions;
  • Ensure engineering and administrative controls are used to limit heat exposure, i.e. ventilation and/or protective clothing;
  • Require employers to maintain records on heat-related illnesses and deaths, and other heat data; and
  • Prohibit retaliation against a covered employee for reporting violations of this standard or exercising any other rights under this bill.

We look forward to working with your offices and the Committee to advance this vital health and safety measure to protect workers from extreme heat and the climate crisis.
