Extreme heat is rapidly becoming one of the most dangerous workplace hazards in the United States, yet millions of workers still lack even the most basic heat protections.

Across agriculture, construction, warehousing, manufacturing, sanitation, food delivery, landscaping, and food service, workers continue laboring through dangerous temperatures without guaranteed access to water, rest, shade, cooling, or emergency response measures. The inadequacy and recission of workplace health and safety policies are dangerous and a broader deregulatory environment that has weakened workplace protections overall while treating labor standards as obstacles to business operations rather than public health necessities.

Federal standards to offer workers sweeping protections in dangerous temperatures have been proposed in the past. Most recently, the Trump Administration has stalled the regulatory process for a Biden-era proposed rule that would have established the country’s first federal heat protective standard, including rights to water and shelter breaks. OSHA, backed by the administration, has also to overhaul or weaken the initial proposal. Following a “business-friendly” approach, the ongoing efforts to limit the authority of administrative agencies, reduce enforcement capacity, and narrow the scope of workplace regulations have left workers increasingly exposed to preventable harm. One result is that heat protections have become another casualty of a political environment that routinely shifts the burden of risk from employers onto workers themselves.

The human consequences are already visible. Extreme heat contributes to tens of thousands of workplace injuries every year. Longterm heat exposure increases the risk of dehydration, heat exhaustion, heat stroke, kidney damage, cardiovascular strain, and death. It also increases the likelihood of secondary injuries by impairing concentration, slowing reaction time, and intensifying fatigue. Workers operating machinery, driving vehicles, climbing ladders, carrying heavy materials, or performing repetitive physical labor in hot environments face heightened danger even when heat is not formally identified as the cause of injury.

The official numbers likely capture only a fraction of the crisis. Heat-related illness and death are consistently undercounted because many workplace injuries linked to extreme temperatures are often categorized differently. Workers can collapse from cardiac events, falls, or have equipment accidents after prolonged heat exposure without those incidents being recorded as related to heat related. Workers paid by quota or productivity metrics often continue working through symptoms of heat exhaustion or stress because stopping can mean lost income, retaliation, or termination.

Recent workplace deaths have made the stakes impossible to ignore. Farmworkers have died harvesting crops during extreme heat waves. Postal workers have collapsed while delivering mail in triple-digit temperatures. Construction workers and delivery drivers have died after prolonged outdoor exposure with insufficient access to cooling and recovery time. Investigations into these deaths repeatedly reveal the same conditions: inadequate training, missing emergency procedures, insufficient water access, pressure to maintain productivity, and employers failing to recognize or respond to clear signs of heat distress. The growing affordability crisis will only further intensify these dangers. Workers in physically demanding, low-paying jobs are often among those most likely to struggle with rising energy and housing costs, making it harder to keep their homes safely cooled during periods of extreme heat. Without adequate recovery in cooler environments between shifts, heat exposure becomes cumulative, increasing the likelihood of illness, injury, and long-term health consequences.

Despite this, the federal government still lacks a permanent occupational heat standard. Existing enforcement largely relies on general workplace safety obligations that have proven insufficient for addressing escalating climate-related hazards. Workers’ safety should not depend on whether federal inspectors intervene after an injury has already occurred.

States have increasingly been forced to fill the vacuum left by federal inaction. Some have developed models that demonstrate what meaningful heat protections can look like.

California established the nation’s first outdoor workplace heat standard and later expanded protections for indoor workers. Employers are required to provide accessible drinking water, shaded recovery areas, paid cool-down periods, heat illness prevention training, and emergency response procedures. Additional safeguards are activated during periods of especially high heat, including closer worker monitoring and mandatory communication systems. California also recognized that indoor workplaces such as warehouses, factories, and commercial kitchens can become dangerously hot environments even without direct sun exposure.

Other states have implemented key standards that mitigate heat related injury:

• Washington developed standards that account for workload intensity and protective clothing requirements rather than relying solely on temperature alone.
• Oregon adopted mandatory acclimatization procedures that require employers to gradually increase workloads for new and returning workers during high heat periods. This is especially critical because workers face elevated risk during their first days of heat exposure.
• Colorado expanded protections to include indoor workplaces where temperatures can become hazardous during summer months.
• Minnesota has long maintained indoor temperature standards in certain sectors, offering an important framework as indoor heat exposure becomes increasingly common nationwide.
• Maryland has also advanced standards that require employers to implement formal heat illness prevention plans and worker training procedures.

These state models offer a clear roadmap for federal policy. Strong national standards should include guaranteed access to cool drinking water, mandatory shaded or cooled recovery spaces, paid preventative rest breaks, acclimatization requirements, indoor heat protections, emergency medical response plans, worker participation in safety planning, and strong anti-retaliation protections for workers who report unsafe conditions. Standards should also account for humidity, workload intensity, duration of exposure, and protective equipment that can intensify heat stress.

None of these policies are radical. Water, rest, cooling, training, and emergency planning are basic workplace safety measures that every single worker deserves. The continued failure to guarantee them reflects political choices about whose health and safety are treated as expendable.

The current patchwork system leaves millions of workers dependent on geography for protections that should exist nationwide. Workers in states without strong heat standards often must rely on employer discretion while facing rising temperatures year after year. Workers earning low wages, immigrant workers, and workers concentrated in physically demanding industries bear the brunt of this failure. Extreme heat is a grave occupational safety issue. It is a structural workplace hazard intensified by climate change and compounded by weakened labor protections. The question is no longer whether stronger standards are necessary, but how many more workers will be injured or killed before comprehensive protections are finally treated as a baseline labor obligation.
