If you smell gas nowLeave the building without using switches, flames, or phones indoors. From outside, call 911 if there is immediate danger and call your gas utility. Contact a private-side contractor only after the area is declared safe.
The short answer
The team should identify meters, risers, branches, affected units, common equipment, and who can authorize shutdowns. Tenant notices and access planning often determine whether diagnosis can be completed in one coordinated visit.
What matters in this situation
Commercial and multi-unit gas work adds operational consequences: multiple occupants, shared piping, equipment schedules, inspection coordination, and the need to document what can safely remain in service.
Details that help define the next step
- Metering arrangement
- Units reporting odor or loss of service
- Shared boilers, laundry, or cooking lines
- Utility shutoff and tag scope
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 metering arrangement and units reporting odor or loss of service.
- Confirm shared boilers, laundry, or cooking lines and utility shutoff and tag scope before the scope is finalized.
- Have unit roster and access contacts and piping or renovation records ready for the onsite team or authority.
- Use the findings to define the appropriate commercial gas line repair scope, required testing, and any next authority or trade.
What to have ready when requesting service
- Unit roster and access contacts
- Piping or renovation records
- Utility incident details
- Owner approval for repair decisions
What not to do
Do not restore one branch until the approved system boundary has passed required checks. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
