Another pump accident

'On Monday, January 28, 2002, a clean coal filter drain pump exploded due to steam build up within the pump, inflicting fatal injuries to the fine coal operator at a preparation plant of an underground mine. The victim was standing approximately 8 feet away at the on/off switch when the pump cover struck him. The pump overheated after almost all liquids had been pumped from the filter drain tank causing the remaining fines to solidify, thus preventing flow. The inlet and discharge lines then became clogged with coal fines causing the pump to become a closed pressure vessel".Read about the accident in this link.
