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

  • Stop all work immediately. Do not continue any task.
  • Do NOT operate any electrical switches, lights, or devices — sparks can ignite gas.
  • Do NOT use your cell phone inside the structure if gas odor is strong.
  • Do NOT attempt to locate the leak if the odor is strong or pervasive — go directly to evacuation.
  • Step 2 — Evacuate if Necessary

    If the gas odor is strong, spreading, or you cannot identify the source:

  • Calmly instruct all occupants to leave the home immediately.
  • Leave doors open as you exit — do NOT lock up.
  • Move at least 100 feet away from the structure.
  • Call 911 and Columbia Gas emergency line: 1-800-344-4077.
  • Call your direct supervisor immediately.
  • Do NOT re-enter the structure until cleared by the fire department or Columbia Gas.
  • Step 3 — Isolate the Gas Supply (If Safe to Do So)

    If the odor is minor/localized and you can safely reach the shutoff:

  • Shut off the gas supply at the main gas shutoff valve or the appliance-level shutoff.
  • Open windows and doors to ventilate the area.
  • Confirm ventilation is adequate before proceeding.
  • Step 4 — Detect and Verify the Leak

    You must verify every suspected gas leak with instruments — never diagnose by smell alone.

  • Retrieve your gas sniffer from your truck (if not on hand, one is stored in the cage at the shop).
  • Use the gas sniffer to scan all gas connections, valves, unions, and flex lines in the area.
  • Perform a bubble test on suspected connections using gas leak detector solution (spray bottle).
  • If leak source is unclear, perform a gas line isolation test:
  • - 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.

  • Document all readings and findings with photos in the customer's Slack channel.
  • 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:

  • Pressure test the repaired section at 10 PSI for 10 minutes — zero pressure drop required.
  • Bubble test all connections with leak detector solution.
  • Use gas sniffer to confirm no residual leaks.
  • Turn on gas slowly and recheck all connections.
  • Test gas flow and operation at all connected appliances.
  • 📸 Photo required: Completed repair with leak test documentation.
  • Step 7 — Documentation and Closeout

  • Document all findings, tests performed, and repairs in ServiceTitan job notes.
  • Upload before/during/after photos.
  • Post summary in the customer's Slack channel.
  • If Columbia Gas was contacted, note their response and any reference numbers.
  • Schedule inspection if required by permit.
  • 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.
