Propane blast inferno rips through Washington company
A dramatic fire and explosion that sent a propane tank flying 1,000 feet has burned five buildings at a company that makes plastic tarpaulins to cover haystacks and set fire to 11,000 tons of hay in central Washington state.
The blaze at Inland Tarp & Liner in Moses Lake closed Interstate 90, the state's main east-to-west freeway in both directions for about two hours.
Grant County sheriff's spokesman Kyle Foreman said the building fires were out by late afternoon, but the nearby haystacks will burn for days.
The county fire marshal's office said the inferno that sent up a towering mushroom cloud of flames and smoke was started accidentally by sparks generated as workers used a saw to cut metal.
No one has been injured.
