Critical safety steps
When in doubt, get out. For everything short of an emergency, these steps apply.
Safe to do now
- Know where your gas meter shutoff is and how to turn it with a wrench.
- Keep the area around the gas meter clear and accessible.
- Install a carbon monoxide detector near gas appliances.
- Note the location of buried gas lines before any digging — call 811 first.
Stop — call a pro
- Never attempt gas line work yourself — no fittings, no extensions, no exceptions.
- Do not use open flame to check for leaks.
- Do not ignore a gas smell hoping it dissipates — leave and call for help.
- Do not bury or conceal gas connections where they cannot be inspected.
From plan to pressure test
Gas jobs follow a strict sequence — plan, permit, install, test. Here is the order.
Safety first: if you smell gas, leave the house and call the gas utility or 911 — do not operate switches or phones inside.
Leak detection: the pro isolates sections and pressure-tests to pinpoint the leak.
Repair or new run: damaged sections get replaced; new appliance runs get sized, routed, and permitted.
Test and verify: every joint is pressure-tested and inspected before gas service is restored.
