Burial beneath dump truck load proves fatal for City of Edmonton worker

EDMONTON - A City of Edmonton worker who was hurt when he was buried beneath a pile of gravel has died.

Occupational Health and Safety says the man was critically injured on the evening of April 22 when a load was released from a dump truck.

The Transportation Services employee was taken to hospital in serious condition and died Wednesday afternoon.

Mayor Don Iveson (EYE'-veh-son) released a statement expressing condolences to the worker's family, saying it's a very painful and difficult time for all involved.

The death comes as officials investigate another workplace fatality in Edmonton involving a man who was buried Tuesday afternoon when a trench collapsed at a construction site involving a private business.

It took several hours to reach the 55-year-old worker because the sides of the trench had to be shored up before emergency crews could start digging. (CHED, The Canadian Press)
