In the summer of 2013, a coal-fired power plant needed to conduct maintenance work on a conveyor belt. The maintenance personnel shut down the fire sprinkler system to avoid any accidental activation during welding. The sparks ignited the coal residue on the conveyor belt.
In the late fall of 2013, a steel plant maintenance team turned off the water supply to the deluge header for fear of freezing. A fire sparked and found its way to an electrical arc furnace. It shot the fire up three floors, burning equipment, property, and injuring five employees.
What do these events have in common? In both instances, the fire sprinkler system was taken offline unsafely. Fires like these occur weekly in circumstances where the fire sprinkler system was taken offline, allowing the fire to grow out of control.
Stop all hazardous activities in the affected area. In the first example above, we see that the coal-fired power plant shut down the wet-pipe for upkeep on the conveyor equipment. But during the maintenance activity, welding and cutting were performed in a coal-handling location. These are very hazardous activities and never should have occurred with the fire sprinkler system offline.

If a fire sprinkler’s water supply needs to be turned off, do it with fire protection in mind. Put a roving fire patrol or stationary fire watch in the area to fight a fire if it ignites; position adequate firefighting equipment in the area of concern. Furthermore, do not forget to contact local safety and the central alarm station to prevent a false alarm.
Always have a professional bring the fire sprinkler system on and offline. To bring a sprinkler system offline, shut the water supply control valve and open the main drain valve. The auxiliary and inspector valves should be open. System and pressure gauges should be at zero
To place the valve back in service, a fire security professional ought to be called. Each type of system has its own procedures to bring back online. Additionally, evaluations and inspections should be conducted to make sure that the system is working properly once it’s back online.
Fire sprinklers are a necessity in power, chemical, and industrial plants. With exceptionally hazardous conditions and plenty of fuel, no chance should be taken when taking your fire sprinkler system on and offline. Be safe and follow appropriate procedures to protect people, plant, and creation.
