About Propane

Propane is a member of the family of liquefied petroleum gases (LPG). It is a colorless, flammable gas with a skunk-like odor at standard temperature and pressure. It is a liquid when stored under its own pressure and flashes to a gas immediately upon release to the atmosphere. It is an asphyxiant and can exhibit anesthetic properties at high concentrations. Continued inhalation can lead to nausea and death. Prolonged contact with evaporating liquid can cause localized freezing and frostbite.

Propane is transported in pressurized cylinders, containers and tank cars using angle plug valves.

Synonyms: Dimethylmethane, LP-Gas, Liquefied Petroleum Gas (LPG)

Accidental Release of Propane

In the event of an accidental release of propane, evacuate the immediate area. Propane is easily ignited and is heaver than air. It is important to eliminate any possible sources of ignition and to provide maximum ventilation. If possible without risk, shut off the source of propane.

Powell Emergency Valve Closure Systems are designed to prevent significant releases of propane. In the case of an accidental release, the propane emergency shutoff system will immediately close the propane valve, preventing a significant release of propane regardless of where the leak occurs downstream of the container.

It is possible to prevent an accidental release of propane. Contact us today to discuss your specific application requirements.
