Explosion in a Electrical Products Plant (673)
An employee was attempting to re-weld a lifting point on a brazing furnace cover. He was using a tungsten inert gas (TIG) welding machine to build up an attachment point on the cover when an explosion occurred. Its force lifted the furnace cover and propelled it against the employee. There were no witnesses to the incident. The furnace had apparently not been evacuated completely of gaseous hydrogen, and this may have triggered the explosion.
