# Congress May Kill Federal Heat Rule Before OSHA Can Enforce It
The Occupational Safety and Health Administration's federal heat safety standard faces congressional elimination before it can take effect. A House committee has moved to block the rule using the Congressional Review Act, a procedural tool that allows lawmakers to overturn recent federal regulations with a simple majority vote.
OSHA finalized the heat rule in May after a decade of advocacy by labor groups and environmental justice organizations. The standard requires employers to implement heat illness prevention measures when temperatures exceed 80 degrees Fahrenheit, including mandatory water breaks, shade access, and modified work schedules for acclimating workers. For indoor workers, the threshold drops to 77 degrees.
The rule addresses a documented gap in workplace protections. Heat stress causes dozens of deaths annually and thousands of hospitalizations among American workers, according to CDC data. Agricultural workers, construction crews, and warehouse staff face the highest exposure. The rule covers roughly 160 million workers across all sectors.
Congressional Republicans argue the regulation imposes excessive compliance costs on businesses. Democrats counter that the costs of heat-related illness, lost productivity, and worker compensation claims far exceed implementation expenses. Labor economists estimate prevention measures cost far less than emergency medical treatment and lost work time.
The rule's timing compounds the stakes. The United States has experienced multiple consecutive years of heat records, with summer 2024 among the hottest on record. Worker heat illness cases spike during extreme heat events, yet many states lack mandatory heat protections.
The Congressional Review Act blocks the rule through a veto-proof mechanism, requiring only 50 Senate votes plus vice-presidential tiebreaker, or a simple House majority. If Congress succeeds, OSHA cannot issue a substantially similar rule without new congressional authorization. The agency could face additional budget constraints that further hamper enforcement efforts.
