Only for individuals qualified, and experienced to work on Natural Gas Lines
When preparing gas pipes, regulators, appliances, equipment and apparatus for service or returning them to service, do not purge their contents into a confined space or where gas can accumulate. Any purging of gas, or purging of air or other contents with gas, should only be done in a well-ventilated area or by safely venting the contents into the outside atmosphere where there are no people, animals, structures or sources of ignition present. Before purging, make sure you identify and eliminate all sources of ignition where gas may be vented, recognizing that natural gas is lighter than air and will rise. Sources of ignition include standing pilots, open flames, cigarettes, electric light switches and appliances, motorized equipment and vehicles, temperatures above 1,100 degrees Fahrenheit and anything that may cause a spark. Use gas detection equipment during all gas release operations to prevent gas from accumulating and creating a combustible or hazardous atmosphere. DO NOT rely on your sense of smell alone to detect the presence of natural gas. The National Fuel Gas Code, the California Plumbing and Mechanical Codes, applicable Building and Safety Codes and local Departments of Building and Safety should be consulted for more information and before any gas release operations begin. Also see the Chemical Safety Board's Safety Bulletin (third party site). When installing gas appliances and/or equipment, the manufacturer's instruction manual should be followed in conjunction with the local code authority.
DO NOT RELEASE THE CONTENTS OF A GAS LINE INTO A CONFINED SPACE. ANY RELEASE OF NATURAL GAS PRESENTS THE POTENTIAL FOR EXPLOSION AND FIRE THAT COULD RESULT IN SERIOUS INJURY AND DEATH. PURGING AND OTHER RELEASES OF NATURAL GAS REQUIRE THE EXERCISE OF EXTREME CAUTION AND SHOULD ONLY BE PERFORMED BY QUALIFIED GAS PROFESSIONALS.
