Two Consumers Energy workers were injured in a flash explosion in an underground storage area in Grand Rapids.
The workers are recovering. Consumers Energy is continuing to investigate the cause of the flash explosion.
They were working in an underground, concrete vault, where electrical-distribution equipment is kept and maintained, when they were burned by an electrical-arc flash, Consumers Energy spokesman Roger Morgenstern said.
Morgenstern described the vault as a “small working area” that also houses equipment.
The work was related to a construction project on Division that includes improved electrical reliability downtown.
“Our thoughts are with the employees and their families as they continue to recover from their injuries”, said Consumers in a statement.
