Propane tank flood safety tips
JEFFERSON CITY, MO
The Missouri Department of Natural Resources and Missouri Propane Gas Association urge citizens in flood-prone areas to secure propane tanks properly and mark the tanks to help identify them and avoid safety problems in the event of local flooding.
Unsecured propane tanks can float, and can be carried away by flood waters. Flood waters can be much more powerful than the strength of connecting pipe or tubing, and may cause a propane tank to float off its foundation if it is not secured.
If a business or citizen is in an area that may be affected by flooding and has a propane tank, the following actions are recommended.
Before the storm or flood:
§ Secure your propane tank to a strongly secured stationary object such as a tree. Secure the tank by running a chain or cable through the legs or lifting lugs of the tank. Cable or chain instead of rope is recommended.
§ If you own the tank, mark the tank with your name, address and phone number in case the tank is carried away. Contact your propane provider if you are not certain if you are the owner of the tank.
§ Take a picture of your propane tank manufactures nameplate. It might be good to have a picture in case your tank is recovered after floating away.
If you have to evacuate to higher ground:
§ Close the service valve on the propane portable cylinder or permanent tank by turning the handwheel clockwise. If flooding causes a propane tank to break away from its location, any gas in the container will be lost if the service valve remains open.
§ Turn off the service valve and the shutoff valve on all propane appliances. Be sure to check first with your propane supplier if you don't know where the shutoff valves are located.
§ When possible, move propane cylinders to a location where they will not be affected by high water and subject to floating. Do NOT relocate cylinders to a garage or indoors.
After the storm or flood:
§ Your tank's service valve should be left off until the system and appliances have been checked by a qualified service person. Do not attempt to restore service yourself—contact your propane provider to arrange for service to be re-stored, pilot lights lit and so on. Missouri state regulations require a safety inspection for any propane systems that have experienced an interruption of service. Only your propane provider is qualified to do this.
§ Your propane supplier should inspect propane-powered household appliances, farm equipment or vehicles with controls or regulators that have been underwater before being put back into service.
§ If your propane tank has moved, do not attempt to move it. This is a job for propane service professionals.
§ If abandoned propane tanks are discovered once floodwaters have receded, contact the department's Environmental Emergency Response section at 573-634-2436.
§ If you smell propane gas, leave the area immediately and contact your fire department to inform them of the situation.
During and after March flooding in southern and eastern Missouri, crews supervised by the department and the U.S. Environmental Protection Agency recovered more than 250 fuel tanks and potentially hazardous "orphan" containers.
The department's Environmental Emergency Response section is called to the scene of more than 300 emergencies each year, including fires, traffic accidents, leaking storage tanks and other incidents that could have a negative environmental impact. The department's 24-hour spill line receives more than 1,600 incident reports annually.
To report an environmental emergency, including fuel spills, please contact the spill line at 573-634-2436. For more information, contact the Department of Natural Resources at 800-361-4827 or 573-751-3443, or visit the department's Web page at www.dnr.mo.gov.
