There are a large number of types and modifications of fire extinguishers designed to extinguish a wide variety of fires, the sources of ignition of which can be flammable materials, chemical reactions, etc.

For example, if we take it, it is more compact compared to OP 5 and OP 8. But, accordingly, it contains less extinguishing agent, although OP 4 is in no way inferior to OP 5 in terms of extinguishing time.

This fire extinguisher is less than twice as heavy as the OP 2, which weighs 3.5 kg. It is also almost two times lighter than OP 8, whose weight is 12.0-12.6 kg. Considering its capacity, this mass is optimal for using OP 4 in any office.

How to use it?

In principle, there is nothing easier than learning how to use such a fire extinguisher. First you need to break the seal. After this, you need to remove the pin, which protects the fire extinguisher from accidental activation. Then you should go to the source of the fire, point the bell at it and press the lever.

Enterprises must constantly check that other workers know how to use fire extinguishers, which is very important, since many lives may depend on it.

A fire extinguisher should not be viewed as an overly safe tool, because once a small fire is extinguished, a larger disaster can be prevented.

Powder fire extinguisher OP-4 is designed to extinguish fires of solid, liquid and gaseous substances (class A, B, C or B, C depending on the type of powder used).

Powder fire extinguisher OP-4 is not intended for extinguishing fires of alkali and alkaline earth metals and other materials, the combustion of which can occur without air access.

A powder fire extinguisher that is universal in characteristics and volume. Attracts with its price-performance ratio. Suitable for equipping premises, construction sites, vehicles.

An effective fire extinguisher for extinguishing all classes of fires, with the widest range of applications. Fire extinguisher OP-4 can be installed as a primary fire extinguishing agent on cars and trucks, special professional equipment, rural tractors and combine harvesters. OP-4 is suitable for service in most climatic zones - operation is possible at negative ambient temperatures of up to forty degrees. Consequently, the use of fire extinguisher OP-4 (z) for completing panels at construction sites, gas stations, and other street facilities of urban social and commercial infrastructure is not prohibited.

The extinguishing agent is completely released from the cylinder in ten seconds. During extinguishing, it is recommended not to release all the powder at once, but by opening the valve for two to three seconds, distribute the fire extinguisher charge over the entire fire area. According to modern fire safety standards, it is believed that in standard-type premises, one product with a volume of five liters is sufficient for two hundred meters of area. Depending on the class of the object, the number of fire extinguishers may vary.

Serviceability is determined by the reading of the pressure gauge; the indicator must be placed in the green indicator area. If the pressure gauge needle goes into the red zone, the fire extinguisher must be recharged. Pressure gauges are checked annually, throughout their entire five-year service life. The OP-4 fire extinguisher is charged with powder of different qualities, which must be indicated on the label. Cheap powders are not suitable for extinguishing class A fires (wood, cardboard).

Technical characteristics of the fire extinguisher OP-4

The product is certified, the OP-4 fire extinguisher has a mandatory fire safety certificate.

Powder fire extinguishers are the most versatile devices, designed to extinguish almost all classes of fires and used over a wide temperature range. The limitation for their use is fires initiated by the ignition of materials that burn without access to oxygen, for example, alkali or alkaline earth metals.

One of the most popular models of powder fire extinguishers is OP-4 (z) - ABCE. If we decipher this abbreviation, we get: a powder fire extinguisher with a nominal mass of fire extinguishing powder of 4 kg, pumped, intended for extinguishing fires of classes A, B, C and E.

Where is the OP-4 powder fire extinguisher used?

Thanks to the technical parameters and versatility of the fire extinguishing powder, OP-4 is indispensable for extinguishing all types of fires, except for the burning of metals (class D):

• class A – combustion of solid objects (paper, wood, plastic, etc.);
• class B – combustion of liquids, both soluble and insoluble in water (gasoline, alcohol, glycerin, etc.);
• class C – combustion of gases (propane, hydrogen, household gas, etc.);
• class E – burning of equipment and installations under high current.

Application of OP-4 at such facilities as:

• public buildings;
• warehouses;
• industrial enterprises;
• household buildings and premises;
• delivery trucks;
• minibuses, –

effective and cost-effective, which has been proven in practice.

Technical characteristics of OP-4

Operation of the OP-4 fire extinguisher is possible over a wide temperature range - from minus 40°C to plus 50°C.

The devices need to be recharged once every 5 years, the service life is 10 years.

These powder fire extinguishers are convenient to use, easy to maintain, effective and safe for humans when extinguishing fires.

Technical parameters of OP-4 (z) are as follows:

1. Capacity – 5 l.
2. The mass of the explosive charge is 4.0±0.2 kg/l.
3. Working pressure – 1.4±0.2 MPa.
4. The duration of powder supply in case of fire is 10 seconds.
5. Jet length – 3 m.
6. Cylinder weight – 6 kg. Dimensions – 13 cm diameter, 42 cm height.
7. Fire extinguishing capacity – 2A (fire class A), 55B (class B).

The principle of exhaust gas release is displacement under the influence of excess pressure, which creates a working gas (carbon dioxide).

How to store powder fire extinguisher OP-4

To store OP-4 indoors, the devices are installed on the floor on special stands or mounted on the wall using brackets. As a rule, the fire extinguisher kit comes with only a hose-socket and a passport for the product, so brackets, stands and other necessary related products are purchased separately.

The location of the OP is selected based on the points of GOST No. 12.4.009. Caring for the OP consists of periodically checking the appearance of the device, the strength of the fasteners, the integrity of the seal, and removing dust and contaminants from the surface.

A more detailed diagnosis of the serviceability of the fire extinguisher is carried out during quarterly maintenance of the device. Once a year, the maintenance company opens the fire extinguisher and evaluates the parameters of the fire extinguisher. Recharging the OP-4 is necessary every 5 years of operation or without fail after activation of the device.

How to activate a powder fire extinguisher OP-4 (z)

In order to activate the OP-4 pump-type fire extinguisher in case of fire, it is necessary to perform the following actions:

• direct the nozzle from which the extinguishing agent will come out to the source of the fire;
• break the seal;
• pull out the fire extinguisher pin, which is a metal rod bent into a ring at the end;
• press the lever.
