Federal workplace safety officials are investigating the death of a Little Elm postal worker who collapsed while delivering mail Monday as temperatures climbed into the triple digits.
Umeshkumar Thakkar, 58, was identified by the National Rural Letter Carriers’ Association. Thakkar, an Aubrey resident, had worked as a rural part-time flexible carrier since 2022.
The Occupational Safety and Health Administration is investigating Thakkar’s death and has up to six months to complete the process, according to the U.S. Department of Labor Office of Public Affairs.
OSHA may examine workplace conditions, review injury and illness records and privately interview employees. If investigators identify safety violations or serious hazards, the agency may issue citations and proposed fines.
The OSHA investigation will focus on workplace conditions and compliance with federal safety requirements. It will not determine Thakkar’s official medical cause of death.
It remains unclear whether heat contributed to his death. A heat advisory was in effect Monday in North Texas, with temperatures reaching about 100 degrees and heat index values climbing even higher.
The Little Elm Fire Department responded about 2 p.m. to the 1600 block of Thornhill Lane. First responders administered CPR, but Thakkar did not survive.
The rural carriers’ association described his death as a “painful reminder” of the conditions letter carriers face while serving the public.
NRLCA President Don Maston urged rural letter carriers to follow heat-safety protocols, stay hydrated, recognize the symptoms of heat-related illness and look out for one another.
“The Postal Service is deeply saddened by the tragic loss of a postal family member on July 20,” the U.S. Postal Service said in a statement.
USPS said it is providing counseling services to employees at the Little Elm Main Post Office while the OSHA investigation continues.
The death comes three years after Dallas letter carrier Eugene Gates Jr., 66, collapsed while delivering mail in June 2023, when the heat index reached 113 degrees. An autopsy determined Gates died from heat exposure and heart disease.
OSHA later cited the Postal Service and proposed a $15,625 fine, alleging it failed to adequately protect employees from high heat, humidity and direct sunlight. The Postal Service contested the citation.
A 2024 report by the Postal Service’s Office of Inspector General also identified shortcomings in the agency’s heat-safety program.
The Postal Service has said its Heat Illness Prevention Program includes mandatory training, hydration guidance and instructions for employees to call 911 if they experience symptoms of heat exhaustion or heat stroke.
Officials have not released Thakkar’s cause or manner of death.
