Water mist application conditions and requirements

A water mist extinguishing system should be refillable water containers clean and fresh water. (Commonly used industrial distilled or treated potable water)

2, the protection zone structure and the doors and windows of the fire resistance of not less than 0.50h, the ceiling of the fire resistance of not less than 0.25h. (This is to prevent the spread of fire outside the protection zone into the protection zone, thus requiring the protection zone of the wall and the doors and windows should have some fire resistance. While requiring the issuance of extinguishing fire to a period of time, building components will not be damage to ensure airtight protection zone, does not cause loss of extinguishing agent, affecting fire effect.)

3, before the start of water mist fire suppression system and the set fan, smoke machines, blowers and pipeline fire damper, smoke damper should be closed automatically. Staff confirmed after the fire should start the smoke machine smoke. (This is because to a protected area being ventilated water mist extinguishing agent release, fire extinguishing agent as soon exhaust air outflow protection zone, the protection zone to reach the design requirements of fire extinguishing agent, seriously affecting the extinguishing effect; another , fire protection zone may also spread through the air duct.)

4, water sprayer mist extinguishing system, you must cut off the fuel, combustion gases of the gas source. (This is to prevent fire expand, to prevent dilution agent discharge strength, impact extinguishing effect.)

5, the nozzle head and nozzle bottle plastic sprayer spray angle between the object of protection should not be within the scope of obstructions. (This is because the memory in the range of the jet nozzle obstruction, will seriously affect the jet effect, which affects the extinguishing effect.)

6, the protection zone should be used doors fire doors open in the direction to evacuate, and can automatically shut down. (This is to prevent the door open in case of emergency, the impact of evacuation. While requiring evacuation door can be automatically shut down, in order to facilitate the protection zone of water mist fire extinguishing water to maintain a certain strength to prevent the loss of extinguishing agent, impact extinguishing effect can be avoided for some reason the person trapped in the protection zone, from the protection zone to open the door smoothly evacuated. protection zone automatic closing doors design, emphasizing when the door is closed, on how circumstances can open from inside the protection zone.)

7, water mist fire extinguishing system equipment should be set at an ambient temperature 4-50 ℃ dedicated equipment room. (This is because the temperature is too low, the water will freeze, the temperature is too high in the tank water temperature, resulting in vaporization and heat exchange, and may have a scale affect water quality. Settings in a dedicated room is to make the fire-extinguishing system equipment to avoid being the impact of adverse weather conditions or subjected to other mechanical damage. while allowing staff to manage and maintain.)
