SPOKANE, Wash. -

Firefighters are treating two Spokane Waste to Energy Plant employees for burns on Tuesday morning.

A firefighter official tells KXLY4 two adult men are in critical condition. Both employees were burned by the steam of a nearby boiler.

The identities of the injured workers won't be released at this time.

The City of Spokane sent out this message in a press release: "Following a serious accident at the Waste to Energy Facility this morning, the residential self haul area is closed for the remainder of the day.  Commercial loads also have been diverted. Customers are asked to take their loads to the North Side and Valley transfer stations." 

The WTE Plant will run with one boiler instead of two while the investigating into the incident continues.
