Eugene Gates Jr. had spent 36 years delivering mail across Dallas, so he understood how difficult Texas summers could be. He knew the importance of carrying water, finding shade when possible and preparing for long hours outside. But even years of experience could not protect him from the heat on a June morning in 2023.
At 7:30 a.m., Gates texted his wife, Carla, about the temperature. It was already 87 degrees.
Later that day, the longtime letter carrier collapsed while delivering mail. A medical examiner determined that hyperthermia, a dangerous rise in body temperature, contributed to his death.
For Carla Gates, the loss was devastating. But in the months that followed, questions about her husband’s working conditions and the safety measures meant to protect postal employees gave her another reason to keep pushing for answers.
Records she examined after his death raised concerns about whether required heat-safety training had actually taken place. Other findings involving workplace complaints, reported heat-related illnesses and delivery vehicles without air conditioning added to those concerns.
The questions have become even more pressing as additional postal workers in Texas have died after medical emergencies during periods of extreme heat.
A familiar face on a Dallas mail route
For the final 15 years of his career, Eugene Gates delivered mail along the same route in Dallas’ Lakewood neighborhood. He served approximately 400 homes a day, building relationships with residents who came to recognize his friendly personality and dependable service.
His wife remembers him as someone who genuinely enjoyed his work.
“Eugene was a man of integrity. He was a man that loved people. He was always smiling,” Carla Gates said. She recalled how much he cared about both the Postal Service and the customers he served.
Preparing for hot weather was part of his daily routine. He regularly filled a cooler with at least eight bottles of water before leaving home.
That routine became more challenging when the ice machine at his postal station stopped working and, according to Carla, was not repaired.
Rather than go without ice, Eugene decided to buy a machine of his own.
His wife offered to purchase bags of ice for him, but he chose to handle the problem himself. Every morning, he made sure he had what he needed before starting his route.
Today, one small reminder of those mornings remains with Carla: the last bag of ice she made for her husband.
“I tried to, I really tried to get rid of it, I just can’t right now,” she said.
The memory reflects the ordinary precautions Eugene took to get through a demanding workday. It also underscores the concern at the center of his widow’s fight: Why should a worker have to find his own solution when a basic resource needed to stay cool is unavailable at work?
Questions over mandatory heat-safety training
In 2022, the U.S. Postal Service introduced a nationwide Heat Illness Prevention Program intended to help employees recognize and avoid heat-related illnesses.
The program calls for heat-safety education and other precautions for workers exposed to high temperatures. USPS guidance identifies April 1 through October 31 as the program’s annual operating period, with additional activation when local weather forecasts indicate that the heat index could exceed 80 degrees Fahrenheit during a workday or shift.
However, records Carla Gates obtained after her husband’s death appeared to show that Eugene had completed required heat-safety training.
She disputed those records, saying her husband never received the training. She also questioned how the completion date could be accurate when it fell on one of his scheduled days off.
“He never had any training whatsoever,” Gates said, alleging that the records had been falsified.
Her concerns were not limited to one employee’s file. Kimetra Lewis, president of the Dallas branch of the National Association of Letter Carriers, said similar problems involving training documentation had been identified in other parts of the country.
A federal audit of the Postal Service’s adverse-weather procedures also identified weaknesses in how heat-safety training was documented and delivered.
In one example, a manager certified 39 carriers as having completed heat training, although records indicated that 17 of them were not working on the certification date.
The findings raise an important distinction between having a safety policy and ensuring employees actually receive the instruction it requires. Training records may show that a box has been checked, but they cannot by themselves establish that a worker understood the risks or knew how to respond to a medical emergency.
The audit recorded 1,332 heat-related incidents nationwide between fiscal year 2022 and June 2024. Separately, records reviewed in the Dallas investigation showed 355 reported incidents at Texas facilities since the program launched.
Those figures cover reported incidents and should not be confused with the number of deaths. Nevertheless, they illustrate the scale of the heat-related safety concerns facing postal workers.
More Texas postal workers have died
Eugene Gates’ death was not the last case to raise alarms about delivering mail in extreme temperatures.
In 2025, Dallas letter carrier Jacob Taylor died after experiencing a medical emergency while working in hot weather.
Then, during the summer of 2026, Little Elm letter carrier Umeshkumar Thakkar died after collapsing while working during an Extreme Heat Warning.
The circumstances surrounding individual deaths can differ, but the cases have intensified calls for a closer examination of working conditions and the effectiveness of existing safeguards.
Lewis said she remains concerned that little has changed for carriers facing dangerous temperatures. She argued that workers need meaningful improvements rather than assurances that safety policies already exist.
For employees who spend hours walking between homes, carrying mail and packages, and returning repeatedly to a delivery vehicle, the risk is not limited to a single stretch of extreme heat. Physical exertion, humidity, direct sunlight and inadequate opportunities to cool down can all add to the strain on the body.
Heat-related illness can also become serious quickly. Warning signs may include headache, dizziness, nausea, unusual weakness and heavy sweating. Heat stroke is a medical emergency that requires immediate attention.
For postal workers, recognizing those symptoms is only one part of the challenge. They also need access to drinking water, opportunities to cool down and clear instructions that make stopping for a medical concern a practical option rather than something that could interfere with completing a route.
Workplace complaints point to gaps in basic protections
Records from the Occupational Safety and Health Administration show heat-related complaints involving postal facilities across Texas, including locations in Dallas, Waxahachie, Killeen, Houston, Humble, Nederland, Beaumont, Galveston, Flint, Fulshear, Angleton and San Antonio.
Several cases highlighted concerns about access to water, workplace conditions and how heat-related incidents were handled.
In Killeen, a carrier was hospitalized with a heat-related illness during a three-day period in 2023. An OSHA citation later found that the employer had failed to report the hospitalization within the required 24-hour period.
In Dallas, a letter carrier reported during the summer of 2026 that limited ice-machine capacity at the Juanita Craft station left employees without access to cool drinking water.
Employees in Waxahachie also raised concerns about the availability of cold beverages and said they feared possible discipline when speaking up about heat exposure.
Taken together, the complaints point to a practical problem: safety measures are only effective when workers can rely on them at the facilities where they begin their shifts and throughout their routes.
Access to water and ice, clear reporting procedures and a workplace culture that takes symptoms seriously can all influence whether an employee gets help before a heat-related illness becomes life-threatening.
Thousands of Texas delivery vehicles lack air conditioning
The investigation also examined the vehicles used to deliver mail across Texas.
Records showed that 18,153 active delivery vehicles were assigned statewide. Of those, 10,337 did not have air conditioning, compared with 7,816 that did.
That means roughly 57% of the listed vehicles lacked air conditioning.
The figures were particularly striking at several North Texas locations:
- Cedar Hill: 30 of 33 assigned vehicles lacked air conditioning.
- DeSoto: 32 of 36 lacked air conditioning.
- Arlington’s Oakwood Station: 39 of 44 lacked air conditioning.
- Plano’s Coit Station: 60 of 70 lacked air conditioning.
Air conditioning does not eliminate the dangers of working outdoors, especially when carriers must walk between deliveries. However, a cooled vehicle can provide an important opportunity to recover from heat exposure between stops.
Without that option, workers may have fewer ways to lower their body temperature during a long shift.
Patrick Pitts, president of the National Rural Letter Carriers’ Association, said a written policy cannot substitute for practical protections on the job.
“The Postal Service has a heat illness prevention program, but a policy on paper is not the same thing as protection on a route,” he said.
Union delegates recently approved a resolution calling for stronger safeguards for carriers working in extreme temperatures.
The proposed improvements include earlier start times, additional breaks, reliable supplies of water and ice, and more air-conditioned vehicles.
USPS says employee safety remains a priority
The Postal Service declined to participate in an interview for the investigation but provided a written statement defending its existing safety measures.
USPS spokesperson Carol Hunt said the agency considers employee safety a top priority and has implemented a national Heat Illness Prevention Program. She said employees receive mandatory heat-related safety instruction and are provided with information and resources to help them work safely.
The agency’s guidance tells carriers to stay hydrated, wear appropriate clothing and hats, seek shade when possible, and carry sufficient water and ice. Employees are also instructed to call 911 if they begin experiencing symptoms of heat exhaustion or heat stroke.
USPS said its heat-safety program operates from April 1 through October 31 and can be activated at other times when National Weather Service forecasts indicate that the heat index is expected to exceed 80 degrees Fahrenheit during a workday or shift. The agency also requires employees at every facility to complete annual heat-stress training.
The statement outlines the precautions USPS says it has established. The records and employee complaints, however, raise questions about how consistently those measures are being implemented in practice.
That distinction is central to the debate over postal worker safety: whether the required training is delivered and accurately documented, whether basic cooling supplies are available, and whether employees can take appropriate steps when temperatures become dangerous.
The wider push for stronger heat protections
The concerns involving postal workers come as federal officials continue to consider broader workplace protections against extreme heat.
The Occupational Safety and Health Administration published a proposed heat-injury and illness-prevention standard in August 2024. The proposal would require covered employers to develop plans for evaluating and controlling heat hazards in indoor and outdoor workplaces.
The proposal is part of a broader effort to establish clearer requirements for protecting workers from dangerous heat exposure. It is not the same as a finalized nationwide standard, and its progress through the federal rulemaking process remains important to follow.
For letter carriers, the immediate concerns are more concrete: dependable access to water and ice, sufficient recovery time, effective training, and vehicles that offer a cooler place to rest between deliveries.
Union leaders say these changes could make working conditions safer, particularly during the hottest months of the year.
For Carla Gates, the issue is deeply personal. She believes her husband’s death should lead to improvements that protect other families from experiencing the same loss.
A widow determined to keep fighting
Three years after Eugene’s death, Carla still holds on to the uniform he wore that day. She also carries postage stamps in her purse, remembering something her husband once told her about supporting the work he loved.
The memories remain part of her daily life, but so does her determination to demand change.
Gates has questioned the training records, raised concerns about workplace conditions and continued speaking out about the risks faced by postal carriers.
She wants more than promises or written procedures. She wants to see evidence that the protections meant to keep workers safe are reaching them where they need them most.
“I want to see results,” she said. “And the only way to see results is that we have to fight.”
Her fight is now tied to a larger question facing the Postal Service: How can a safety program be considered effective if employees and families continue to raise concerns about whether its protections are working as intended?
For the carriers who still head out each morning in the Texas heat, the answer could have life-or-death consequences.
