1. Foam Fire Extinguishing

Foam fire extinguishing is a set of actions to eliminate fire. A foam or a wetting solutions are used as a fire extinguishing agent in foam fire extinguishing systems and installations. Fire fighting equipment for systems includes foam generators, foam storage and dosing systems, fire filters, proportioners, etc.

Pozhneftehim recommends using modern efficient foam fire extinguishing installations. The customer engages us in as a company responsible for designing, production, supervision, commissioning and maintenance during the further operation of the complex of fire fighting equipment and foam concentrates.

1.2. Advantages of foam fire extinguishing

The foam fire extinguishing installations makes it possible to effectively isolate fuel from oxidizer and cool the seat of fire. This significantly reduces water consumption and effectively limits the spread of flame.

Air-mechanical foam is divided into low, medium and high expansion foam. Depending on the foam expansion ratio, foam fire extinguishing installations are divided into installations (systems) for area and volume fire suppression. There is also a method of subsurface suppression of oil and oil products in reservoirs with flammable and combustible liquids.

When choosing a fire extinguishing method, it is necessary, in accordance with the "Technical Regulations on Fire Safety Requirements" No. 123-FZ dated July 22, 2008, to identify the object of protection according to the functional fire hazard class, fire resistance level, category of buildings, structures and premises by fire and explosion hazard (for production sites).

3.3. Classification of foam fire extinguishing installations according to Russian standards

Requirements to automatic installations of foam fire extinguishing are established by GOST 12.3.046 and GOST P 50800. The systems are divided by design into sprinkler and drencher types (electric, pneumatic, hydraulic, etc.).

Foam fire extinguishing installations have different response time, that is, the period of tume before the system starts releasing the fire extinguishing substance:

• up to 3 seconds (high-speed response)
• up to 30 seconds (medium-speed response)
• more than 30 but less than 180 seconds (slow response)

Classification of foam fire extinguishing installations by duration of action:

• short duration systems (less than 10 minutes);
• average duration systems (less than 15 minutes);
• long duration systems (15 - 25 minutes).

Regardless of the response time and duration of foam extinguishing, any foam extinguishing installation contains the following elements:

• Water source, pumping station
• Foam concentrate storage and dosing system
• Foam sprinklers, foam generators
• Target fire equipment and block-modular solutions (fire filters, fire stabilizers, fire foam cabinets, block-containers, etc.)
• Water and mortar pipelines

Pozhneftehim recommends to take the foam expansion ratio as the basis for the classification of foam extinguishing installations. By this criterion, the systems are divided into:

• fire extinguishing installations with low expansion foam (expansion from 5 to 20);
• fire extinguishing installations with medium expansion foam (expansion over 20, but not more than 200);
• fire extinguishing installations with of high expansion foam (expansion over 200);
• fire extinguishing installations with wetting agent.
