You cannot smell natural gas in its natural state, so we add chemical to help you detect its presence. This chemical, called mercaptan, has a strong odor very much like rotten eggs.

• If you smell even the faint odor of mercaptan or hear a hissing noise, notify others in person-not by phone-to leave the premises, and then leave.
• Do not light matches or use lighters. Extinguish cigarettes or other smoking materials.
• Do not turn appliances or lights on or off. Do not use the telephone. Electrical currents in switches and telephones may spark an explosion.
• After you leave the potentially affected are, call 1-888-482-4950 to report a gas leak, or call 911.
• Remain away from the building until an official familiar with the situation tells you it is safe to return.
• Once your gas has been shut off, do not try to turn it back on. Only a qualified person may perform this task.
