Local opinion: Arizona needs stronger heat safety laws

Sebas was a young immigrant worker from Guatemala with a long life ahead of him and a loving family. He took an agricultural job in Maricopa County, hoping to earn enough to put a down payment on a house. The searing June sun beat down on Sebas’ shoulders as he harvested cantaloupes, making him feel weak and lethargic. Later that day, his spouse received a life-changing call: Sebas was found unconscious, lying face-down in the field. Despite efforts to resuscitate him, he was ultimately pronounced dead from hyperthermia.

Sadly, Sebas’ tragic passing is not an anomaly. Extreme heat claims 1,500 to 1,700 lives annually, with nearly one-third of these deaths occurring in Maricopa County alone. As temperatures rise across the Southwest, outdoor workers increasingly face life-threatening conditions daily.

Outdoor workers in construction, agriculture and mail delivery spend much of their day exposed to extreme heat. Wearing protective clothing, using heavy machinery and standing on heat-retaining surfaces further amplify that exposure. As a result, a difference of just a few degrees outside can quickly transform benign discomfort into heat stroke, permanent organ damage, or death.

Some may contend that individuals have a responsibility to protect themselves during periods of extreme heat by staying hydrated, seeking shade and limiting outdoor activity. However, this argument overlooks the fact that heat-related illnesses often develop gradually and impair one's ability to recognize danger. For example, heat stroke can cause disorientation or unconsciousness, leaving the victim unable to seek help or take protective action independently. This scenario was likely the case for Sebas.

The physical dangers of heat are only part of the problem. Many workers have little control over whether they can stop working when conditions become unsafe. Broadly speaking, society relies on these services, and disruptions often have supply chain consequences. As a result, employers face pressure to maintain productivity and profits, which can lead to unsafe working conditions. Furthermore, workers cannot simply step away when conditions become unsafe. In addition to lost wages, immigrant workers face the threat of retaliation or deportation, making them less likely to report unsafe conditions or seek care.

As evidenced by thousands of heat-related emergency department visits and hundreds of preventable deaths each year, current regulations are proving inadequate. Although extra breaks and cooling measures seem to hamper productivity, no one benefits economically from restricting breaks. For an uninsured individual, an emergency room visit can cost $1,500 to $3,000 for basic care, while more complex care can easily exceed $5,000. Employers face workers' compensation costs, decreased long-term productivity, and the loss of experienced employees. Ultimately, preventing heat-related illness is far more cost-effective than treating it.

The path to protecting outdoor workers lies in stronger protections and meaningful enforcement. Currently, Arizona relies on guidance from the Occupational Safety and Health Administration (OSHA) to regulate working conditions but does not have specific statewide legal standards for protections or enforceability. Arizona recently adopted heat-safety recommendations encouraging employers to provide water, shade, rest breaks, training, and heat illness prevention plans. While these measures represent meaningful progress, they remain largely advisory and lack enforcement standards.

Worker advocates and members of Arizona's Workplace Heat Safety Task Force have called for binding heat standards that establish hazardous temperature thresholds, require mandatory rest breaks, and impose clear penalties on employers who fail to protect their workers. Arizona should follow the lead of states like California, where enforceable regulations have been associated with significant reductions in heat-related worker deaths. Every outdoor worker, regardless of immigration status, deserves the right to report unsafe conditions without fear of retaliation and to return home safely.

Sebas came to Arizona seeking opportunity, not a death sentence. His story illustrates the human cost of treating heat safety as a recommendation rather than a requirement. As Arizona experiences longer and more intense periods of extreme heat, policymakers must move beyond voluntary guidelines and implement enforceable heat-safety standards. The evidence is overwhelming: extreme heat poses a grave danger to outdoor workers. The question is how many more preventable illnesses, hospitalizations and deaths Arizona is willing to accept before taking action.
