Gas Line Leak Detection, Immediate Evacuation & Shutoff Safety

Natural gas (methane) and propane gas leaks present immediate explosion and carbon monoxide toxicity hazards. Natural gas is odorless by nature, so utility providers inject Mercaptan—a chemical with a pungent "rotten egg" smell—to alert occupants to leaks.

Life-Safety Evacuation Checklist

If you smell rotten eggs, hear a high-pitched hissing near a gas appliance, or detect dying indoor vegetation near a gas line:

1. EVACUATE IMMEDIATELY: Get all occupants and pets out of the structure into fresh open air.
2. DO NOT TOUCH ELECTRICAL SWITCHES: Do not flip light switches, use phones inside, or start vehicles nearby. Any static micro-spark can ignite accumulated gas.
3. Shut Off Gas at the Main Meter (If Safe): Use a wrench to turn the gas meter valve a quarter-turn so the long bar is perpendicular to the pipe.
4. Call 911 & Emergency Gas Plumbers: Contact your gas utility emergency line and call our master gas line plumbers at (855) 397-0871.

How Master Plumbers Repair Emergency Gas Leaks

• System Pressure Gauge Testing: Pressurizing isolated line sections with air to confirm 100% airtight integrity.
• Black Iron & Corrugated Stainless Steel (CSST) Repair: Replacing corroded nipples, valves, and flex connectors.
