Gas Leak Response Protocol
Purpose
This SOP establishes the mandatory response procedure for any suspected or confirmed gas leak encountered during a Spartan Plumbing service call, installation, or inspection. It applies to all service technicians, install technicians, and apprentices.
⚠️ This is a safety-critical SOP. Deviation from this protocol is grounds for immediate corrective action.
When to Use
- You smell natural gas (rotten egg / sulfur odor) at a job site or in a customer's home
- Your gas sniffer or gas leak detector triggers an alert
- A customer reports a suspected gas leak
- You discover a gas leak during pressure testing, bubble testing, or routine inspection
- A gas appliance installation or repair requires leak verification
Procedure
Step 1 — Assess Immediate Danger
Step 2 — Evacuate if Necessary
If the gas odor is strong, spreading, or you cannot identify the source:
Step 3 — Isolate the Gas Supply (If Safe to Do So)
If the odor is minor/localized and you can safely reach the shutoff:
Step 4 — Detect and Verify the Leak
You must verify every suspected gas leak with instruments — never diagnose by smell alone.
- Shut off all gas appliances.
- Close the main gas valve.
- Connect a pressure gauge to a test port.
- Pressurize the line to 10 PSI.
- Hold pressure for 10 minutes.
- Any pressure drop confirms a leak in the system.
Step 5 — Determine Response Path
| Situation | Action |
|---|---|
| No leak confirmed (instruments show no leak) | Document the negative result. Inform the customer. Do NOT sell a repair for a leak that doesn't exist. |
| Minor leak at a fitting/connection | Tighten the connection, retest. If resolved, document and proceed. |
| Leak at flex line, union, or valve | Present repair options (Good/Better/Best). Get customer authorization before proceeding. |
| Multiple leaks or main line issue | Contact Columbia Gas to verify. Present options including full gas line test and potential reline. Consider financing options for large jobs. |
| Leak cannot be located or stopped | Shut off gas at main. Contact Columbia Gas. Do NOT leave gas on. |
Step 6 — Repair and Re-Verify
After any gas leak repair:
Step 7 — Documentation and Closeout
Important Notes
- Never diagnose a gas leak based on smell alone. The negative Google review incident demonstrated the reputational damage from false diagnoses. Every suspected leak must be instrument-verified.
- Never collect payment for gas leak repair without verified, documented evidence of the leak. This protects both the customer and Spartan.
- Always offer the customer the option to contact Columbia Gas for independent verification before committing to repairs, especially for large-dollar jobs.
- Pregnant women, elderly, and children — if present, bias toward evacuation even for minor-seeming leaks.
- Gas sniffer batteries — check your sniffer at the start of every shift during your vehicle inspection.
- If in doubt, shut it off and call. It is always better to shut off gas and escalate than to leave a potential leak active.
