The U.S Propane industry has a proud safety record, with strong emphasis on sound engineering principles, up to the minute employee safety training & educating consumers on the safe application of propane.

The transfer of propane from tank trucks to the consumer storage tanks is done with the use of pumps. Various valves and accessories are required by NFPA 58 and the U.S Department of Transportation (DOT) to ensure the safety of the transfer operation. Below you will find a listing of the typical valves that are found on containers or used during the transfer of liquid propane to residential storage systems.

  • Pressure Relief Valves
    Propane tanks are fitted with pressure relief valves which open and close to prevent a build up of excessive internal tank pressure.
  • Excess Flow Valves
    These valves are typically found on storage tanks, at the loading facility or bulk head and on the delivery vehicles themselves. This valve is designed to automatically shut off flow during the transfer of liquid propane if the flow exceeds the valves settings. This may occur if the piping downstream of the valve is broken.
  • Line Valves
    These valves are used to control flow into or out of the system and are manually operated. They are also used to isolate piping for maintenance purposes.
  • Remote Shut Off Valves
    This is a DOT approved system that allows the delivery operator to shut of the trucks main valve if a leak is detected. These are fitted to all new bobtail delivery trucks and by 2006 will be fitted to all existing bobtails.

The propane industry has a high level of safety excellence, whether it is during delivery and transportation of your propane fuel or storage and application. Every precaution and safety measure is taken to ensure safe and effective utilization of your propane fuel. Please contact your supplier dealer if you have any questions regarding the safe use, storage and delivery or your propane fuel.

Propane won't ignite when combined with air unless the source of ignition reaches at least 920 degrees Fahrenheit. In contrast, gasoline will ignite when the source of ignition reaches only 430 to 500 degrees Fahrenheit.
