• Primary Shut-Off Location: Main Basement Mechanical Room (Room 01).
• What It Controls: All domestic water flowing to individual apartment units and common areas.
• Operation: Locate the main intake line near the water meters. Turn the primary wheel valve clockwise to stop the water flow.

• Operation: The main breakers are housed in the heavy grey metal enclosures. Individual residential zone switches are clearly labeled by floor. [1]

4. Main Gas Supply

• Primary Shut-Off Location: Exterior Utility Enclosure (Rear of the building, near the loading bay).
• What It Controls: Natural gas lines serving central water heaters, building boilers, or individual unit appliances.
