Firefighting occupies a very important position in life. We all know to call 119 in case of fire, but do you know how to choose the nozzle of a fire extinguisher? In fact, the fire extinguishing nozzles used in different occasions are different. The following are:Bus fire sprinkler nozzleLet’s take a look at the manufacturers:

1. In general public places, such as offices, shopping malls, restaurants, entertainment venues, guest rooms, etc., use nozzles with an operating temperature of 68°C; in kitchens, use nozzles with an operating temperature of 93°C.

2. In places with high decoration requirements such as exhibition halls, restaurants, conference rooms and hotels, you should choose ceiling-type sprinklers or other decorative sprinklers with beautiful appearance.

3. When the steam pressure is less than O. For the space within 2m near the 1MPa radiator, use nozzles with a high operating temperature of 121 to 149°C; within 2 to 6m, use nozzles with a medium operating temperature of 79 to 107°C for the side where the air heat flow tends.

4. Above the steam pipe with insulation O. 76m and O. on both sides. For spaces within 3m, nozzles with a medium operating temperature of 79-107℃ should be used; within 2m next to the low-pressure steam safety valve, nozzles with a high operating temperature of 121-149℃ should be used.

5. In the stuffy roof of a wooden or corrugated iron roof with neither insulation nor ventilation facilities, or under a glass skylight exposed to sunlight, sprinklers with a medium operating temperature of 79 to 107°C should be used.

6. You can choose side wall sprinklers in the corridor.

7. When there is corrosive gas erosion at the fire scene, anti-corrosion nozzles should be used.

8. You can choose upright or pendant sprinklers according to different roof structures.

9. When the pipeline has concealment requirements or the distance between the pipeline and the roof panel is restricted, a pendant sprinkler head should be used.

10. In a dry system, if the nozzle installation method is pendant, dry pendant nozzles should be selected.

11. When buildings and structures are equipped with automatic sprinkler systems, there should be spare sprinkler heads in stock. The total number should not be less than 1% of the installed number, and the number of spare sprinklers of each type and temperature should not be less than 10.

The above describes the types of fire extinguishing nozzles to choose for different occasions, but the fire situations that may occur in different occasions are also different, so you should also pay attention to the temperature level of the fire extinguishing nozzle. Choose a nominal temperature level of the fire extinguishing nozzle that is 30°C higher than the ambient temperature to confirm that the fire can be extinguished successfully.
