The question of how to find out the expiration date of a fire extinguisher is not the most difficult, although it occurs quite often. To answer this, you need to understand the model line of fire extinguishing agents, because they are all filled with different fire extinguishing agents. And accordingly, each of them has its own service life.
The expiration dates of fire extinguishers and the rules for their operation are established taking into account fire safety standards and requirements. This applies not only to industrial facilities, but to private homes and even cars. Therefore, when purchasing a device, you need to check its passport, which should indicate the date of charging the unit and the inspection.
If a fire extinguisher is purchased for an industrial facility, retail and entertainment establishments, public buildings, hotels, boarding schools, schools and others, then it must be registered in a special journal, which indicates its expiration date. In this case, all actions related to the fire extinguishing device must be recorded in the log. This is its recharging, repair and examination. That is, a fire extinguisher is a completely controllable device.
Today manufacturers offer four main types:
- powder,
- carbon dioxide,
- based on foam solutions: water and air;
- aquatic.
Shelf life of powder fire extinguisher
The shelf life of an OP largely depends on what powder is used in it as a fire extinguishing agent. The category is divided into three groups:
- downloads,
- gas generators,
- self-acting.
The first ones work on the principle of pushing out the powder with an inert gas, which is pumped into a cylinder under a pressure of 8-12 kg/cm², as indicated by a pressure gauge installed on the body. Either nitrogen or carbon dioxide, rarely air, is used as an inert gas. By the way, you need to check the pressure once a quarter, which must be recorded in the fire extinguisher registration log.
As for the capital inspection, and therefore the survey, it is carried out once every five years. In this case, powder units are checked for the quality of the powder. To do this, several pieces are selected, the number of which must correspond to 3% of the total amount of fire extinguishing agents located at the facility. For example, if an enterprise uses 100 fire extinguishers, then any 3 are selected for testing.
They are opened and checked to see what condition the powder is in, whether there are any large lumps in it, and what color it is. If everything meets the quality requirements, then the fire extinguishing devices (the rest) should be in perfect order.
As for the shelf life of indoor powder fire extinguishers, everything will depend on the brand of powder used in them.
- PSB-3M. This powder has a shelf life of only 4 years. It can be used to extinguish class B and C fires.
- Wexon-ABC. Shelf life – 5 years. From the marking it becomes clear that such fire extinguishing agents are used to extinguish class A, B and C fires.
- Foscon. This type of powder is used to extinguish class A, B, C and E fires. Its shelf life is 10 years.
Fire extinguisher OP-4: technical characteristics, expiration date
Using the example of the OP-4 brand, let’s look at both the expiration dates and technical characteristics of the device.
- The number “4” shows the capacity in liters and the mass of the powder, respectively.
- The total weight of the device is 7 kg.
- This is a portable type of fire extinguishing agent.
- Injection type, where the pressure is 1.4 MPa.
- OTV spraying occurs within 10 seconds. Spraying distance – at least 3 m.
- The service life of the OP-4 powder fire extinguisher is 10 years.
- Temperature limit for use is from -40C to +50C.
Two other types
Gas generator models are cylinders filled with powder, in which a capsule filled with gas acts as a pressure distributor. During operation, it breaks under the action of the lever rod, and the cylinder is filled with gas under pressure.
Self-triggering models are fire extinguishers filled with both gas and powder, which are triggered by high temperatures.
Their shelf life also depends on the type of powder that is placed inside the container.
Carbon dioxide
This type of fire extinguishing devices differs from powder ones in that carbon dioxide (in a liquefied state) is pumped inside the cylinder. Therefore, such a characteristic as stable pressure inside the cylinder is the main one when talking about (OU-3, for example).
Therefore, there are certain requirements:
- check devices quarterly for the presence of pressure, there are certain deviations that are not taken into account - up to 5%;
- once a year a technical condition check is carried out, where pressure is also taken into account;
- Once every 5 years, a recharge is made regardless of whether the pressure inside the cylinder is maintained or not.
And although the shelf life is up to 15 years, they are recharged in any case every 5 years. OU brands are checked for the presence of fire extinguishing agent by weighing the device. That is, the unit stored on site must be weighed every year and the resulting value compared with the passport data. If the deviation is more than 5%, then it is sent for recharging. But even if after the expiration of the guaranteed period the pressure inside is normal, the fire extinguisher is still taken out of service and transferred to charging with new fire extinguishing gas.
It turns out that the carbon dioxide fire extinguisher OU-3 and the tests are almost identical to the powder OP-4. Although these are completely different brands of fire extinguishing agents with different fillers.
Foam and water
The worst negative characteristic of foam and water is metal corrosion. It often appears at joints and on the housing. Therefore, fire extinguishers of these types must be checked once a quarter. And they are specifically tested to identify areas with rust. If such are detected, the device must be sent for repair and recharging.
But regardless of whether rust spots are found on the body of the unit or not, once a year such units are replaced with new ones. There is no point in recharging them, because negative exposure to moisture is corrosion of the internal planes of the cylinder, which cannot be restored. That is, the shelf life of these brands is one year.
Automotive
Cars use either powder or carbon dioxide fire extinguishing devices. There are certain requirements for their volume: powder for 2 liters, that is, OP-2, carbon dioxide for 2 or 3 liters.
As for the expiration date:
- powder - this is 2 years for recharging and up to 10 years for operating the cylinder;
- carbon dioxide - 5 years for recharging and up to 20 years for operation.
There are two ways to determine whether a fire extinguisher is suitable. First, to do this you need to pay attention to the label pasted on the body of the device. It has Roman and Arabic numerals on the side. The first ones show the month, the second ones show the year of manufacture. A piece of paper should be torn off underneath them. That is, this is the starting point for the expiration date.
The second is the fire extinguisher passport, in which the manufacturer must indicate the number when the device was charged with a fire extinguishing agent.
The release date, also known as the charging date, must be included in order to facilitate control over when to carry out repairs, recharging and inspection, or a complete replacement. Taking into account the standards described above, you can easily determine when it is necessary to inspect the units, taking into account the date of their manufacture.
Taking into account all of the above, we can conclude that fire extinguishers of any type must be inspected for their quality condition at least once every three months, starting from the date the device is put into operation. This is a strict standard, which is supported by the work of the person in charge of the facility, the owner of a private house or car. At enterprises and institutions, these actions must be recorded in the fire safety equipment logbook.
Powder fire extinguisher, portable (OP). Necessary for fighting fire (fire) of solid materials, gases, liquids and electricity. installations. Weight up to 6 kg.
Powder fire extinguishers are in great demand when fighting fires of solid materials (category A), various metals and their derivatives, flammable liquids (category B), including various gases (category C) and electricity. power plants with a load of no more than 1000V. Basically, this type of fire extinguisher is used for a relatively small fire area, which makes it possible to use it in crowded places. It is permissible to use these small-capacity fire extinguishers (up to one liter) to fight fires in a car engine.
In email installations, including el. switchboards can use fire extinguisher models with automatic activation. In the warm season, if such el. systems are not equipped with additional cooling, there is a high risk of fire. In such cases, experts recommend not to neglect the installation of fire alarm sensors, because this can save not only the equipment itself, but also avoid casualties among people.
