Modern fire engines are usually equipped with steel ladders, water guns, portable fire extinguishers, self-contained breathing apparatus, protective clothing, rescue tools, first-aid tools, etc. Some of them will also be equipped with large fire-fighting equipment such as water tanks, water pumps and foam fire-fighting devices. Common types of fire trucks include water tank fire trucks, foam fire trucks, pump fire trucks, ascending platform fire trucks, and ladder ladder fire trucks.
Dry powder foam fire truck use precautions:
1. Regularly check whether the dry powder in the dry powder tank is agglomerated. When adding dry powder, prevent impurities from getting into it.
2. Perform a water pressure and airtight test on the dry powder tank every five years according to the specified pressure, keep it for 3 minutes, the pressure gauge value should not drop, and there should be no leakage or abnormality in each weld.
3. After the dry powder gun (cannon) is used, the inner cavity should be purged in time to avoid corrosion and block the dry powder gun (cannon).
4, often check the nitrogen, dry powder pipe joints, valves, find problems, and solve in time. Check the pressure inside the nitrogen cylinder every three months. When the pressure inside the bottle is lower than 12MP, it should be re-inflated.
5, dry powder car (dry powder foam combination vehicle) in the fire field should be based on the actual situation of the fire, accurately calculate the amount of dry powder required to extinguish the fire, while the dry powder car (dry powder foam vehicle) as close as possible to the fire source , aiming at the fire point, and strive to extinguish it once. When using dry powder trucks for petrochemical fire rescue, the fire commander should mobilize the corresponding forces as needed to do the cover work. At the same time, consider using the foam car to attack and prevent re-ignition, which provides a strong guarantee for successful firefighting.
