A powder fire extinguisher can extinguish any fires, except for electrical installations and equipment, which are energized above 1 kV. After use, OP can form a powder cloud that is hazardous to human health.
Powder fire extinguisher is a device for extinguishing a fire, consisting of a durable metal body, into which powder is pumped under high pressure to extinguish the flame. A powder fire extinguisher is used to extinguish fires and fires with an area of no more than 2 m, at an air temperature ranging from -50 to + 50 ° C.
Features of use
The OP fire extinguisher can extinguish suddenly ignited gaseous, solid and liquid combustible substances, as well as electrical wiring under a voltage not exceeding 1 kV. The same applies to electrical installations, electrical receivers and other similar devices. A powder fire extinguisher must not be used to extinguish substances that can burn even without the aid of oxygen. If the jet of a fire extinguisher hits electronics, radio and television equipment, it can be damaged. Valuable antiques, paintings, books and other antiques treated with the contents of the cylinder may become unusable.
How to bring a fire extinguisher into working condition
1. Take the OP in hand and approach with it at the maximum possible, but safe distance to the fire site. For effective use of the extinguishing agent, it is enough to approach 2-3 m.
2. On the locking and starting device located in the upper part of the powder fire extinguisher, you need to break the seal, pull the pin out of the socket and release the hose nozzle, directing it to the fire site.
3. Having pressed the lever - the trigger for supplying the contents of the cylinder, you need to wait a few seconds, which are necessary to bring the fire extinguisher into combat readiness. Direct the resulting jet towards the ignition source.
If the fire was extinguished in a closed or too small room, it is recommended to ventilate it immediately after extinguishing the fire source, since the air in the room can be heavily gassed or dusty. Human health can be severely damaged by the formation of a powder cloud. If the fire was extinguished by several fire extinguishers, it is necessary to ensure that the jets do not collide with each other, otherwise the participants in the extinguishing of the fire may get injured.
It is necessary to store a dry powder fire extinguisher in a room where the air temperature does not exceed 50 ° C. Do not place the cylinder near heating and explosive devices, as well as near those that are under high voltage. The fire extinguisher should always be in the field of access and in a visible place. The shelf life is 10 years. The cylinder must be recharged at intervals of 5 years. It is unacceptable to hit the body of the fire extinguisher and allow it to fall. A fire extinguisher with cracks, dents and swelling on the body must not be used. The same applies to damage to the locking and starting device and leakage of the connection of its nodes.
