Reminds me of the cause of the Apollo 13 oxygen tank explosions:
"The high temperature emptied the tank, but also resulted in serious damage to the teflon insulation on the electrical wires to the power fans within the tank. The exposed fan wires shorted and the teflon insulation caught fire in the pure oxygen environment."
