When there is no fire, the following items should be checked regularly:
(1) Check for any dripping or leakage in the system pipelines, valves, etc; Check if the water level of the fire water pool and fire water tank is normal; Is the liquid level control valve and float valve at the inlet of the water tank flexible in opening and closing.
(2) The fire hydrant water supply system equipped with a stabilizing device should be regularly checked for accurate and flexible control of the stabilizing pump start stop water replenishment, and the water pressure displayed on the system pressure gauge should be checked for normality.
(3) Regularly open the experimental fire hydrant to check the accuracy of the control system action, and also to start the operation of the main fire pump to avoid mechanical or electrical failures caused by long-term stagnation of the fire hydrant system.
(4) Check if the water gun, hose, and fire button inside the fire hydrant box are damaged or missing, and check if the control valves on each fire riser are in the open state.
When a fire breaks out indoors, the handle of the fire hydrant box near the fire source floor should be quickly pulled open or the glass on the box door should be shattered. Connect the water hose and water gun, and open the fire hydrant valve to spray water to put out the fire. At the same time, press the fire alarm button to notify the fire control center, issue an alarm signal, and connect the fire main pump for water supply.
In systems equipped with voltage stabilizing devices, water from the fire water tank is generally used within 30 seconds, and after exceeding 30 seconds, the fire main pump is started to continuously supply water for extinguishing the fire. After extinguishing the fire, close the fire hydrant valve and wipe the water hose and the inside and outside of the box clean. Glass breakage should be replaced in a timely manner. If a hammer type fire alarm button is used, the safety glass needs to be replaced for future use.
