Warning signs should be posted in every oil house to alert personnel to the presence of combustible materials. If flammables are used or stored, or Class II combustibles are used in such a way that they must be treated as flammables, then the applicable signs warning of the hazards associated with these materials should also be posted. Standard warning placards complying with OSHA or other applicable safety regulations relative to flammables or combustibles are generally available. "No Smoking" signs, in red, should be prominently displayed and the no smoking rule rigorously enforced.

Hand fire extinguishers and automatic systems are essential for oil house safety. Hand operated fire extinguishers should be mounted at strategic points throughout the oil house, particularly near those areas where cleaning tanks are located. They should be inspected periodically (at least as frequently as required by applicable fire regulations) to be sure that they are in satisfactory operating condition. 

Fire extinguishing methods for flammable or combustible liquid fires include the following:

1. Suppression of vapor by foam
2. Cooling below the flash point by water spray or fog (not a direct stream, which could spread the fire!)
3. Excluding oxygen, or reducing it with carbon dioxide, to a level insufficient to support combustion
4. Interrupting the chemical chain reaction of the flame with dry chemical agents or a liquefied gas agent

All personnel employed in the oil house should be thoroughly instructed in the location and use of the fire extinguishing equipment.

Rags, paper, or other solid materials that have been soaked in flammable or combustible liquids should be placed in an approved type of disposal container with a selfclosing cover. The container should be emptied at the end of each shift and the contents removed to a safe location for reconditioning or incineration. All spills should be cleaned up promptly. If an absorbent is used, it should be swept up promptly, placed in an approved disposal container, and removed to a suitable disposal area.
