Propane signs, their application and compliance

What is Propane?

Propane is colorless and, in its natural state, an odorless gas. It is usually shipped as a liquified compressed gas and a foul-smelling odourant is added in most applications. Propane is most commonly used as a fuel (also used as a refrigerant, solvent and aerosol propellant).

As an extremely flammable gas, it is important to take extra precautions when handling and storing propane. Sources of ignition such as sparks, open flames and smoking should be prohibited in places where propane is used, handled, or stored. OSHA 1910.110 provides clear guidelines for safe storage and handling of these materials. Containers in storage shall be located in areas that minimize exposure to excessive temperature rise, physical damage, or tampering by unauthorized persons. Cylinders should not be stored near exits, stairways or in areas normally used or intended for the safe exit of people.

When handling propane, the use of proper personal protection equipment is recommended to avoid exposure or injury. Liquified propane may cause frostbite if in contact with skin. Suitable gloves, eye/face protection, protective clothing and shoes should be worn. Propane gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen, proper caution should be taken when entering confined spaces to make sure sufficient oxygen is present.

Transport Information

Hazmat Placards are required for the transportation of propane. Domestically in the US, the Department of Transportation allows the display of the indentification number UN1075 and use of this number should be consistent on package markings, shipping papers, and emergency response information. Internationally, the transport of propane may require the use of UN1978 placard.
