TWINSBURG TOWNSHIP, Ohio (WOIO) – The Summit County Sheriff’s Office says a Cleveland man died in a workplace incident Friday.

It happened around 9:45 a.m. at Emerald Transformer on Highland Road in Twinsburg Township.

According to the sheriff’s office, the victim entered a tank to conduct an air quality test as two other people waited outside.

When those people noticed the victim was unresponsive, they tried to help him, according to the sheriff.

The 35-year-old, later identified as Dalion Ambler, was sadly pronounced dead on the scene.

The Twinsburg Fire Department described the tank as a railroad tanker car parked behind the facility.

The fire department says they have determined the man died due to the “oxygen deficient atmosphere” of the tank.

The fire department said the victim was a contractor from Clean Harbors, hired by Emerald Transformer to test and clean rail tanker cars.

19 News obtained the following statement from Clean Harbors:

“We can confirm the passing of a Clean Harbors employee today at a customer worksite. Our deepest condolences go out to the employee’s family, friends and colleagues affected by this tragic loss. The well-being and safety of our employees is of the utmost importance to us, and we are working closely with the authorities to investigate the circumstances surrounding this terrible incident.”
