1. Construction of fire fighting system – fire protection by water:
Before constructing a fire protection system with water, it is necessary to clearly define the products needed for this process including: outdoor fire box, indoor fire box, fire hose reel, fire hose, coupling, Fire angle valve, piping system and fire pump.
Then the company will comply with the plan and exactly according to the design of fire protection system installation that has been handed over to you.
3. Construction of fire fighting system – automatic fire protection Sprinkler:
Sprinkler automatic water fire fighting system is the most popular fire extinguishing system today.
+ The applications of this system are suitable for high-rise buildings, factories, buildings…
+ Not suitable for installing IT server room areas or products with highly damaged properties when facing water.
Advantages: Fast, easy installation and not costly as other specialized fire fighting systems.
Materials needed for construction of fire protection system: Sprinkler nozzle, fire pump system and pipeline, fire valves, fire alarm valves (Alarm Valve), fire alarm lights, fire alarms.
4. Construction of fire protection system – fire fighting by foam foam:
Fire extinguishers, piping systems, fire valves, fire alarm systems. This system is mainly used for fire fighting of gas stations
Foam fire extinguishing systems are now used quite a lot because it reduces the amount of water needed, reduces the number of fire extinguishing agents in the fire, reduces environmental pollution, and for high expansion foam, most as if there was no damage to the goods, and within a short time the whole warehouse was back to normal.
Foam extinguishing systems are used in areas with a high risk of fire and explosion, carefully selected, requiring proper foam concentrates, foam mixing systems, foam spraying equipment, and Effective coordination between these components in a fire-fighting system.
Fire extinguishing system foam, when activated, will spray a type of foam covering the surface of gasoline, separating the flammable liquid from the air and the fire, thereby extinguishing the fire.
The foam mixing system can be either “balanced pressure” or “inline”.
The foam nozzle can be a sprinkler, spray, nozzle, monitor, foam pourer, or high expantion foam generator, depending on the foam system used.
2. Fire-fighting principle:
Depending on the type of foam, you can fight fire in several ways:
Either use a foam to cover the surface of the combustible with a thick layer of foam, extinguish the flame and isolate the fuel from continued exposure to air, or cool the fuel with the amount of water contained in the foam. or cover to prevent liquid (fuel) from evaporating and mixing into the air.

3. Fighting FM 200:
It is a clean gas fire fighting system, safe for the environment and people, and has high safety standards. Used for oil and gas industries, medium and high voltage transformer stations. Banks, Treasury, Library….
The air fire extinguishing system FM-200 (HFC-227ea) Air Fire is manufactured according to the ISO9000 quality standard and UL Listed certified.
Air Fire FM-200 is a fire extinguishing system designed at operating pressures of 25 bar and 42 bar.
The Air Fire FM-200 fire extinguishing system is designed with a variety of tank sizes to suit each fire zone. The system uses 13/26/40/67/75/120/240 liter tanks.
Application:
This system is suitable for clean environments where people work, and is equipped with high value machines or data.
– Central computer room
– Electrical, electronic, telecommunications equipment, storage equipment
– High-value warehouse, treasury
– Art galleries, museums
– Laboratory, medical equipment room
– Petrochemical plant, oil and gas station at sea, oil and gas pump station
Advantages:
– Fast – Efficient: discharge 30 seconds right after receiving the fire alarm signal from the central control cabinet
Safety: FM-200 is certified to be non-toxic, no harm to humans, no environmental impact, no electrical conductivity, no damage to electronic equipment.
– Economy: Do not affect the equipment in the fire area, reduce disposal costs after the fire.
4. Construction Of Fire Fighting System For Wall:
Concept:
The wall fire fighting system is a non-automatic fire extinguishing system, consisting of: Water pump – one way, two way valves – pressure relief valve – overpressure protection valve – hand valve – wall fire cabinet – flexible hose to carry water (also known as a tornado), when a fire occurs, the firefighters run to the fire cabinets located inside or hung on the wall (the inside contains water hoses that are stacked or rolled up. ) quickly roll or pull the hose closer to the fire site. then install the spray steering wheel on the end of the wire, the other end is installed on the axis of the cabinet. one person holds the hose tightly, the other opens the water supply valve at the cabinet to spray water into the fire.
Principle of Operation:
Fire fighting water systems include a plumbing system linked to a fire pump, a fire hose (Hosereel) and a fire hydrant. When a fire incident occurs, the user will put the fire hose spraying water directly into the fire to extinguish.
The process of installing a wall fire extinguishing system includes the following steps:
– Step 1: Design complete wall fire fighting system.
– Step 2: proceed to submit documents, suppliers and products.
– Step 3: submit all kinds of samples and supplies.
– Step 4: Submit construction drawing.
– Step 5: prepare human resources.
– Step 6: Prepare all kinds of construction equipment
– Step 7: execution.
5. Construction of fire protection system by CO2:
Characteristics of gas CO2:
CO2 is a colorless, odorless, non-conductive gas, and is a highly effective extinguishing agent. The CO2 automatic fire extinguishing system is used intelligently, reliably and quickly controls the fire before it damages property. The characteristic of CO2 gas is to spread very quickly, so it is capable of fighting effectively.
Order of fire fight activation:
– There is a fire:
* Smoke / heat sensor trigger fire alarm signal (1)
* Control cabinet receives fire alarm signals transmitted from the detector (2)
* The control cabinet transmits fire alarms that emit a bell / horn / light, and at the same time activate the gas fire extinguisher valve
* The fire alarm activates the ringing, the gas spray indicator lights up
* CO2 extinguishing gas is sprayed from the gas tank, along the gas pipeline (3), then sprayed and spread through the gas nozzles installed in the fire area
* The fire will be extinguished
6. Extinguish fire with powder or gas portable bottles:
BC, ABC, CO2, MFZ4, MFZ8, MFZ32, MT3, MT5, MT32 fire extinguisher, trolley fire extinguisher, motorcycle fire extinguisher, car fire extinguisher.The construction of fire protection system for the works is an urgent matter according to the provisions of law. Construction of a fire protection system not only ensures safety for themselves and the community, but also creates safety trust for construction works.
