Do this before troubleshootingLeave the building. Do not use switches, flames, appliances, or a phone indoors. From outside, call 911 if there is immediate danger and call your gas utility. Do not re-enter until responders say it is safe.
The short answer
The outage may be related to the timing without being the root cause. Equipment can fail to relight, a standby generator may start, or air movement may reveal an existing leak. Diagnosis begins only after the emergency boundary is cleared.
What matters in this situation
Odor, hissing, or a detector alert changes the order of operations: protect people first, then diagnose the private-side piping after the utility or emergency responders say the area is safe.
Details that help define the next step
- Which appliances attempted to restart
- Whether a generator or fireplace operated
- Alarm activity and outage timeline
- Any appliance error codes observed from outside or after clearance
These details help establish scope; they do not replace an emergency response, onsite inspection, utility decision, permit requirement, or manufacturer instruction.
How a careful service process is organized
- Start by documenting which appliances attempted to restart and whether a generator or fireplace operated.
- Confirm alarm activity and outage timeline and any appliance error codes observed from outside or after clearance before the scope is finalized.
- Have approximate outage and odor times and affected appliance list ready for the onsite team or authority.
- Use the findings to define the appropriate emergency gas leak repair scope, required testing, and any next authority or trade.
What to have ready when requesting service
- Approximate outage and odor times
- Affected appliance list
- Utility findings
- Recent service or storm damage
What not to do
Do not repeatedly reset breakers or appliance controls in a building with a gas odor. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
