Chevron Refinery Fire

Probably won't turn out to be much. When I worked at Dow in TX in the late 1970's, we had a fire every few months. They ran hydrocarbon thru furnaces to crack it, so every time a rusty tube broke, .... They had fire-fighting hose stations set up around the furnaces and the Operators were expected to play Smokey. Most of a refinery is steel, so unless the fire lasts long or burns controls cables it isn't hard to stop.
