In recent years, whenever incidents of fire or explosion, we always use the fire extinguishers as well as fire-fighting system to extinguish the fire and bring the safety of people as well as property protection.
Not everyone knows the fact there are no fire-extinguishing agents, the scope of application like?
The popularity of the current fighting:
1. Firefighting foam
- Extinguishing foam is created from the combination of foaming agent solution and air through a foaming system
- When the foam is sprayed on the fire, the foam layer formed on the surface of the fire reaches a certain thickness of the foam will work to isolate flammable substance with oxygen and prevents the escape from the surface of the little fire, fire gases
- Firefighting foam longer cooling effect, because the foam itself is made up of water and cold water as the effects of fire and flammable, resulting in fires are extinguished
- In addition it also dilutes the effects, when foam is destroyed at high temperatures. Water will vaporize and mix with the steam, combustion gases go into the fire.
- Firefighting foam lighter weight than other drugs
- Firefighting foam usually used for fighting fires burning liquids such as gasoline; oil…
- Firefighting foam is non-toxic and not harmful to the device.
- Investment costs higher equipment
- Unusable for fire D, E, F.
2. Fire fighting dry powder
- As extinguishing chemical is mixed with the solid, finely include one or more principal components
- When injected into the combustion reaction, the powder does not absorb the heat but also inhibits burning chemical reaction
- When putting powder into the fire, the powder particles will occupy the volume of the reaction zone of fire, it reduces the oxygen levels fall below 14%.
- Fire extinguishing powder fast and can extinguish fires many different types
- What harmless powder on human biochemistry, and animal creatures
- Low investment costs, are commonly used.
- Do not use the powder for fire fighting equipment such as high-precision electronic devices
- Fire powder does not have the effect of cold so the fire could flare up again
- Fire hydrophilic powder, hygroscopic so very lumpy and play basis.
3. Fire fighting water
- Water is a liquid colorless, odorless, tasteless
- When sprayed into the fire, it absorbs the heat of the fire and reduces their temperature until the fire was extinguished
- When mixed with water vapor gas mixture concentrations slightly reduce fire danger
- When sprayed into the fire water acts covering the surface and penetrate flammables prevent the evaporation of the burning gases.
- Countries with large heat absorption capacity leads to lower the temperature of the fire quickly
- Low cost, is widely used and very popular
- Can use water to mix with other extinguishing
- Can spray on the fire at a distance
- For electrical equipment fire, if power has not been cut when spraying can lead to electric shock, fire shutter electrical equipment.
- Special use of water for fire fighting chemicals need to determine the chemical is flammable substances? Should we use water for fire fighting or not? Also not recommended fire fighting water with inflammables like paper, documentation, library …
- Fire water freezes at low temperatures of about -10 degrees C.
4. Fire fighting Carbo dioxide
- Gas is colorless, odorless, when breathed in high concentrations create acidity in the mouth, and tingling in the nose and throat
- Due to its inert gas C02 is not only dilute the concentration of fire, but also reduces the oxygen concentration falls below the value of maintaining the fire
- Used mainly for extinguishing the fires of liquids, gases and electrical equipment.
- CO2 clean, non-corrosive, does not damage the material which it is exposed
- The price is cheaper than the other fire extinguishing agent
- CO2 asphyxiation danger it causes to people, affecting health
- Effective fighting in space is not high and where there are strong winds.
5. Fire fighting HFC
- Liquefied gas is used to extinguish the fire, the gas is colorless, odorless and non-conductive
- HFC gas is a clean gas, which is used to fire the A, B, C, E, is -16.4 ° C boiling point and freezing temperature is -131.1 °C
- When the substance is injected into the fire burning, it will penetrate and extinguish the fire by absorbing heat and quickly extinguished. Especially the sprinkler pipe Blazecut extinguishers used HFC gases, it extinguished the fire immediately and protect the motor cars, boats, cabinets IT …. no fire incident it.
- Gas withstand changes in temperature, non-conductive
- Do not leave a surplus, without causing damage to the equipment, materials in contact
- No cause ground-level ozone, the cost is cheaper than CO2 gases; N2 …
- Non-toxic, safe for human health
- Non-corrosive and completely biodegradable.
- HFC is widely used for fire fighting equipment such as electrical control cabinet, room Server, automotive engine compartment; bay boats; mechanical machines with high accuracy
- With technology growing fighting, now it has been studied and applied to automatic fire HFC for electrical cabinets; control cabinet, such as automobile engine compartment sprinkler pipes Blazecut. Indirect fire systems and live a very effective and very low cost.
