What is the expiration date of the foam solution in the fire foam system, and when is it replaced?

Fire foam liquid can also be called water film-forming foam fire extinguishing agent, or light water foam fire extinguishing agent. Mainly composed of fluorocarbon surfactants.

Fluorine-free surfactants (carbon-chloride surfactants or silicones.

surfactants) and additives to improve foam properties (foam stabilizers, antifreeze, co-solvents and thickeners).

etc.), and water composition. Everything has its own shelf life.

And the shelf life of everything is also different. The same goes for firefighting foam fluids. How long is the fire foam liquid valid for? What happens when it expires?

According to the national standard: GB15308 2006 "Foam Fire Extinguishing Agent".

It is stipulated that the validity period of YE protein foam fire extinguishing agent and FP fluoroprotein foam fire extinguishing agent is 2 years, but if the storage environment is good, the validity period can be extended by 1 year; AFFF water-forming foam fire extinguishing agent, the state stipulates that the validity period is 8 years, if the storage environment is good, the validity period can be extended for 2 7 years. The national stipulation of SAR anti-soluble foam fire extinguishing agent is 2 years, and if the storage environment is good, the validity period can be extended by 1 year. g. The validity period of the national regulations for high multiple foam fire extinguishing agent is 2 years;

According to the above national standards, we will find that in fact, the validity period of the fire foam liquid is value-added, so even if the fire foam liquid purchased by you is marked with 2 years or 8 years on the product instructions, if it is stored well, it may be extended to 3 years or 15 years.

When the fire-fighting foam liquid expires, it can be judged whether it can be used after testing and testing according to the storage situation of the product, and do not rush to replace it. If the test confirms that the fire foam has expired, it should be replaced in time.

To purchase fire-fighting foam liquid, you should go to a regular manufacturer, such as Xinxiao Fire Protection, which has been committed to the production and sales of foam fire extinguishing systems for many years, and is a trustworthy fire-fighting equipment. Factory.

Only the water-forming foam liquid is valid for 8 years, and the rest are valid for 2 years.

According to the relevant provisions of the current national standards, the storage validity period of the aqueous film-forming series is 8 years, and all anti-solvent types are 2 years, because after 2 years, the probability of the failure of the anti-solvent components is larger, 3 years for ordinary synthesis, 3 years for class A fire extinguishing agent, high and medium power fire extinguishing agent, 2 years for aqueous fire extinguishing agent and other fire extinguishers, and 2 years for protein and fluoroprotein series.

According to the national fire safety code, ordinary foam fire extinguishers are valid for one year, and the agent must be replaced before they can continue to be used.

The validity period of the aqueous film-forming foam is 8 years, and the other is basically two years. Shandong Qili Fire Production and Sales of Water Film-Forming Foam Liquid, Anti-soluble Water-Forming Foam Solution.

2 years validity, mandatory replacement.

2. Regardless of whether the fire extinguisher has been used or unused, it must be sent to the maintenance unit for hydrostatic test inspection when the specified period has reached the specified period from the date of delivery.

1) Portable and cart-type fire extinguishers, portable and cart-type dry powder fire extinguishers, and portable and cart-type carbon dioxide fire extinguishers must be inspected after five years, and every two years thereafter.

2) Portable and cart-type mechanical foam fire extinguishers, portable water fire extinguishers for three years, after every two years, must be carried out hydrostatic test inspection.

3) Portable and cart-type chemical foam fire extinguishers and portable acid and alkali fire extinguishers must be tested and inspected for two years after the expiration of two years, and every other year thereafter.

The validity period of water-based foam fire extinguishers has two aspects, namely the cylinder and the fire extinguishing agent.

1. The signal cylinder of the water-based fire extinguisher:

According to the relevant national regulations, the mandatory scrapping life of the first water-based fire extinguisher is six years.

2. Fire extinguishing agent of the water old people-based fire extinguisher:

When stored at normal ambient temperature, the validity period is two years, but generally speaking, the replacement period of the extinguishing agent is one to two years.

For the use of fire extinguishers that have reached the following specified years, the building use management unit needs to send repairs to the fire extinguisher maintenance enterprise in batches:

1) Portable and trolley water-based fire extinguishers have been shipped for 3 years, and every 1 year after the first maintenance.

<> "Foam fire extinguishers are valid for several years.

Fire extinguishers are a very common type of fire-fighting equipment, there are many types of fire extinguishers, but fire extinguishers also have a shelf life, so how many years is the validity period of foam fire extinguishers.

Depending on the type of fire extinguisher, usually the validity period of portable foam fire extinguishers is 8 years, while the service life of pressure storage portable foam fire extinguishers can reach 10 years, and the cart type foam fire extinguishers are also 10 years, and the validity period of trolley storage pressure foam fire extinguishers is 12 years. The specific service life of these fire extinguishers should be determined according to the model and production date on the bottle body, and the fire extinguisher must be inspected once a year.

What to pay attention to when using a fire extinguisher.

1. When using fire extinguishers to extinguish fires, attention should be paid to the scope of application of different types of fire extinguishers. For example, foam fire extinguishers are suitable for extinguishing liquid fires, but not flammable and flammable water-soluble liquid fires; Carbon dioxide fire extinguishers are used to extinguish fires in precision equipment and documents, but not in potassium, magnesium, aluminum and other materials.

2. The fire extinguisher hall also has a shelf life, for example, the effective time of carbon dioxide fire extinguishers is 12 years, the effective time of dry powder fire extinguishers is 10 years, and the validity period of water-based fire extinguishers is 6 years. Everyone should have their fire extinguishers checked and repaired regularly. According to the relevant regulations, water-based fire extinguishers are repaired for the first time 3 years after delivery, and every 1 year after the first repair.

In addition, the fire extinguisher should be sent to the designated unit location after each use to check the performance of the fire extinguisher.

3. Fire extinguishers should be stored in a dry, ventilated and easily accessible place. Under normal circumstances, the ambient temperature of the fire extinguisher should be in the range of minus 10-45 degrees, and it cannot be placed upside down, exposed to the sun, rain, etc. For example, the frost and sun protection measures must be taken every winter and summer to avoid the failure of carbonic decomposition.
