Heating or Plumbing Emergency Shutdown

To perform a building-wide emergency shutdown of the heating or running-water systems, you need a key to the boiler room.
These instructions are also posted on the boiler-room door.

CAUTION: THE BOILERS HAVE OPEN FLAMES—KEEP YOUR CLOTHING CLEAR!
THE VENTS AND PIPES ARE HOT AND CAN CAUSE SERIOUS BURNS—BE CAREFUL!

To shut off the building's heating system:
  • A Turn off the heating-boilers shutoff switch (electrical, red box).
  • B Turn off the heating-pumps shutoff switch (electrical, red box).
  • C Turn off the heating-system shutoff valve (plumbing, yellow lever)
To shut off the building's hot/cold running-water system:
  • D Turn off the hot-water shutoff switches (electrical, red box).
  • E Turn off the running-water shutoff valve (plumbing, yellow lever).
The red-box electrical switches are like standard light-switches: up is turned on, down is shut off.
The yellow plumbing levers allow water to flow when the lever is parallel to the pipe, and shut off the flow when the lever is perpendicular.

The yellow plumbing-valve levers are difficult to reach safely. If you cannot reach them, shutting off the red-box electrical switches will still help. But do not turn off either the heating or the running-water system's plumbing valves without also turning off that system's electrical switches.

For each letter above (A-E), the correspondingly labeled photos below show the specified switches or valves. And the correspondingly labeled places in the boiler-room floor plan (amid the photos below) show the location of each of the specified switches or valves.
