Asunción Valdivia Heat Illness, Injury, and Fatality Prevention Act of 2025
A BILL
To direct the Secretary of Labor to promulgate an occupational safety and health standard to protect workers from heat-related injuries and illnesses.
Sec. 2 Employer duties
Sec. 3 Worker heat protection standards
Design of standards—
In general— The Secretary shall promulgate a worker heat protection standard that, in accordance with the best available evidence, establishes the maximum protective program of measures an employer shall implement to regulate employees’ exposure to heat stress and prevent heat-related illness and injury that attains the highest degree of health and safety protection to the extent feasible.
Considerations—
Demonstrably achievable measures— The Secretary may presume that any requirement substantially equivalent to a requirement adopted by a State plan approved by the Occupational Safety and Health Administration pursuant to section 18(c) of the Occupational Safety and Health Act of 1970 (29 U.S.C. 667(c)) and that has been in effect for at least 1 year is feasible.
Prioritizing worker protection— In weighing any considerations during rulemaking, the Secretary shall place preeminent value on assuring employees a safe and healthful working environment.
Available expertise— If the Secretary adopts any finding or recommendation by the Institute, the American Conference of Governmental Industrial Hygienists, or the National Academies of Sciences, Engineering, and Medicine relevant to heat stress in a rulemaking pursuant to this Act, such finding or recommendation shall be considered the best available evidence.
Employer categories— The Secretary may, in any rulemaking analysis or design of standards, cluster relevant employers in any categories such as standard industry or occupational classifications or any common or related features of heat sources, conditions of employment, employer practices, employee characteristics, or nature of place of employment that, in the Secretary’s reasonable determination, are useful for designing an effective and practicable program of standards, regulations, and enforcement that maximizes the health and safety of employees.
Protective programs—
In general— In addition to measures specified by this Act, the Secretary may develop a worker heat protection standard with such additional requirements that, in the Secretary’s reasonable judgment, are necessary or appropriate to achieve the purposes of this Act. Such measures may include the following:
Engineering controls— Requirements to eliminate hazardous levels of heat stress through engineering controls, such as isolation or shielding of employees from sources of heat, exhaust ventilation, insulation of hot surfaces, or climate-control technologies, as well as technology-based standards that encourage the development of such controls.
Administrative controls— Requirements to limit exposure to hazardous levels of heat stress by adjustment of work procedures, work schedules, or other work practices.
Personal protective equipment— Requirements to provide, at the employer’s expense, personal protective equipment such as water-cooled garments, air-cooled garments, heat-reflective clothing, and cooling vests.
Health-related protocols— Requirements to conduct medical symptom monitoring, emergency response protocols, medical removal protection, or training of employees and supervisors in recognition of symptoms of heat-related illness and appropriate responses.
Training requirements— Requirements to train employees and supervisors in topics reasonable or necessary to achieve the implementation of the requirements of a standard or the purposes of this Act, including—
training of employees in signs and symptoms of heat-related illness, emergency response procedures, and their rights under this Act; and
training of supervisors in monitoring heat conditions and environmental forecasts, recognizing signs of heat-related illness, and protocols for responding to likely heat-related illness.
Planning requirements— Requirements for a heat illness and injury prevention plan that—
is of sufficient quality to effectuate the purposes of this Act and to effectuate the requirements of the standard that apply to the employer;
is developed, updated, and implemented with the meaningful participation of the employer’s employees and, where applicable, such employees’ representatives, for all aspects of the plan;
is produced and maintained in writing and updated in light of changing conditions or practices; and
is made available, upon request, to any employee, the employee’s representative, and the Secretary.
Standard health and safety measures— Any measures described in section 6(B)(7) of the Occupational Safety and Health Act of 1970 (29 U.S.C. 655(B)(7)).
Innovative solutions— As the relevant scientific evidence develops, technological solutions improve, and environmental conditions or new work practices aggravate the risk of heat-related illness or injury, the Secretary may modify, supplement, or revise a worker heat protection standard by rule in order to improve such standard in light of such changes, even if it departs from long-standing past practice, provided that the resulting standard is consistent with this Act.
Core practices— The Secretary shall establish criteria under which an employer who exposes or may reasonably be anticipated to expose an employee to heat or heat stress that is not reduced below hazardous levels by engineering controls or personal protective equipment shall implement a reasonable program that includes—
suitably cool potable water or appropriate hydration, provided at employer expense;
periodic paid rest breaks scheduled to reduce heat stress below hazardous levels;
access to shade or suitable cool-down spaces;
acclimatization policies; and
such measures that are necessary or appropriate to ensure effective implementation of the requirements of this subparagraph.
Other specifications—
Protection of pay— The Secretary shall require that, for any required duration such as rest breaks, medical removal protection, and training, an employee shall receive compensation at the regular rate at which such employee is employed.
Language access— Any required training, poster, label, hazard alert, or written plan shall be provided in English and a language understood by the employees, if such is not English, and prepared appropriately for the vocabulary, educational level, and literacy of the employees.
Temporary labor camps— The Secretary shall revise the Secretary’s standard for temporary labor camps to the extent necessary to achieve the purposes of this Act.
Maintaining protection— No worker heat protection standard promulgated under this Act may reduce the protection afforded employees by an existing worker heat protection standard.
Initial standards— Not later than 1 year after the date of enactment of this Act, the Secretary shall promulgate, without regard to the requirements of chapters 5 and 6 of title 5, United States Code, subchapter I of chapter 35 of title 44, United States Code (commonly known as the “Paperwork Reduction Act”), or the National Environmental Policy Act of 1969 (42 U.S.C. 431 et seq.), an interim final rule establishing a worker heat protection standard and related recordkeeping and reporting requirements. Such rule shall take effect upon issuance (except that it may include a reasonable delay in the effective date), shall have the legal effect of an occupational safety and health standard as defined by section 3(8) of the Occupational Safety and Health Act of 1970 (29 U.S.C. 652(8)), and shall remain in effect until superseded by a final rule promulgated pursuant to this Act.
