These guidelines explain the properties and uses of propane and the investigative methods to be used when a fire is believed to have resulted from the use of propane.
Abstract
Propane is a hydrocarbon fuel which is liquified for normal use. It is stored and shipped in steel pressure containers. When investigating fires associated with propane, investigators should check all lines, valves, and connections. Although propane is rarely used in arson, the investigator should not rule out arson as a cause of a propane appliance fire. The first step in the investigation should be a thorough survey of the exterior of the structure. The debris blown from the scene will give an idea of the force of the explosion and will indicate whether a high explosive was used. The investigator should take color photographs and make notes to document the location of the damage on the structure. Damage near the top of the structure indicates that propane was not the cause of the explosion, since propane is heavier than air. The investigator should also check the storage facility and the regulator on the storage tank for signs of leaks resulting from tampering. Other areas which should receive attention are the control valve on the furnace, the sides of the furnace, flexible tubing, and joints. The investigators should also contact witnesses to determine whether they noticed the smell of the odorant which is added to the propane by the manufacturer. Footnotes and six references are provided.
