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 map should identify meters, manifolds, labeled customer-side valves, equipment served, locked areas, and any valves that are inaccessible or in poor condition. It is an operations document, not permission for untrained staff to operate valves during a leak.
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
- Existing labels and drawings
- Meter/manifold locations
- Equipment and tenant branches
- Access and key control
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 existing labels and drawings and meter/manifold locations.
- Confirm equipment and tenant branches and access and key control before the scope is finalized.
- Have floor or site plan and equipment schedule 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
- Floor or site plan
- Equipment schedule
- Facility contact list
- Known abandoned piping
What not to do
Do not label or instruct staff to operate utility-owned valves. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
