Fire when opening a level gauge connected to a molten sulphur tank

In a molten sulphur tank in a refinery, receiving of molten sulphur was stopped as the level gauge was not working. When instrument personnel opened the top side of the level gauge, a fire started as there was pyrophoric iron sulphide inside the level gauge top chamber. The H2S inside the tank also caught fire.

Are you training your operators on the hazards of storing molten sulphur?
