When it is produced propane is odorless and colorless. For safety and detection purposes, a chemical odorant (ethyl mercaptan) is added to propane. The presence of the odorant alerts you of a potential propane gas leak. The wonderful and distinctive smell of propane has been described as something like rotten eggs or a dead animal.
NO FLAMES OR SPARKS!
Immediately put out all smoking materials and other open flames. Do not operate lights, appliances, telephones, or cell phones. Flames or sparks from these sources can trigger an explosion or a fire.
LEAVE THE AREA IMMEDIATELY!
Get everyone out of the building or area where you suspect the gas is leaking.
SHUT OFF THE GAS.
Turn off the main gas supply valve on your propane tank if it is safe to do so. To close the valve, turn it to the right (clockwise).
REPORT THE LEAK.
From a neighbor’s home or other nearby building away from the gas leak, call your propane retailer right away. If you can’t reach your propane retailer, call 911 or your local fire department.
DO NOT RETURN TO THE BUILDING OR AREA…
until your propane retailer determines that it is safe to do so.
GET YOUR SYSTEM CHECKED.
Before you attempt to use any of your propane appliances, your propane retailer or a qualified service technician must check your entire system to ensure that it is leak-free.
