Written by DignanThe Saturday blast sent a fireball into the sky over the Atlas Castings and Technology foundry. It could take days to find out why the delivery truck, loaded with 8,000 gallons of propane, exploded, authorities said.
The truck driver, identified as Charles McDonald, 64, was in critical condition at a Seattle hospital Sunday. Three others injured in the blast were released from a Tacoma hospital, authorities said.
An Atlas executive said the company had accounted for all 32 employees who were at the plant Saturday.
