Close the supply valve or main. A fire sprinkler system should only be shut off by people qualified to do it, because the building loses fire protection.
Keep everyone out of standing water near panels, outlets and equipment. Have a qualified electrician or the utility de-energize electrical rooms.
Open loading docks, elevators and parking near the affected area so crews can bring in truck-mounted units, hoses and pumps.
Large standing water near electrical equipment is a shock hazard. Sewage or flood water requires protective handling.
A broken or activated sprinkler head can release large amounts of water fast, across several floors.
Mechanical rooms, risers and ceiling lines can flood offices and units below before anyone notices.
Ground floors, parking garages and below-grade spaces collect water during heavy rain and storm surge.
Contaminated water needs protective handling and disposal. See sewage backup cleanup.
If a sprinkler system is out of service, the building may need a fire watch until it is restored. Check with your fire alarm company, sprinkler contractor or local fire department.
