At least one person was critically injured Monday afternoon in an explosion at a wood-pellet manufacturing plant in Entwistle, Alta.
Parkland County fire crews were called at about 2:20 p.m. to the Pinnacle Renewable Energy plant, about 100 kilometres west of Edmonton, said Sarah Mate, director of community services for the county.
STARS air ambulance airlifted a 28-year-old man to the Royal Alexandra Hospital, STARS spokesperson Tammy Yamkowy said.
About 40 members of Parkland County fire services were on scene, Mate said, and were assisted by Yellowhead County firefighters.
An Occupational Health and Safety spokesperson said members were on scene Monday evening.
Pinnacle Renewable Energy has eight wood-pellet production facilities in Western Canada, according to the company website.
Commercial production at the Entwistle plant started in June 2018.
