What are the fire extinguishers can be used to extinguish electrical wiring

A fire - it is the worst thing that can happen at a power plant, and so it is extremely important to prevent this phenomenon, and if it occurs as quickly as possible to eliminate. In this article, I'll tell you what species of fire extinguishers put out the permissible wiring of different voltage class.

What we are told the rules

So first, let's find out what we say Code of Practice, namely JV 9.13130.2009. And it says the following:

1. With powder extinguishers extinguish allowed to 1 kV.

2. Carbon dioxide fire extinguishers to put out a fire is allowed up to 10 kV.

3. In the case, if the concentration of water vapor in the carbon dioxide more than 0.006 and not the jet of extinguisher more than 3 meters, then a similar carbon dioxide fire extinguisher is allowed to produce extinguishing fires only up to 1 kV.

It seems everything is simple and clear, but everywhere has its own quirks. Let's deal with them.

existing varieties

Water and foam

Extinguishers used in the add foam or an aqueous base (AFP VGIs, OS) are used for quenching ignition wiring only in those cases where it received a special permit from the Manager.

In all other embodiments, the use of aqueous foam fire extinguishers and extinguishing fire in electrical prohibited.

Fire extinguishers

If a fire occurred in a network up to 1 kV, with the help of powder fire extinguisher to extinguish the hearth even possible without disconnecting the wiring. Maximally effective in extinguishing burning insulation fire extinguisher OP series.

Note. For home use powder extinguisher is a great option, because in the house voltage is greater than 400 volts is used.

Carbon dioxide

This type of extinguisher is best to extinguish the electrical equipment, and a series of op-amp stands out carbon dioxide.

These extinguishers extinguishing chamber at the expense of low temperature quenching substance. Which allows not only to deprive the heat source flow of oxygen, but also cool the last detail.

The only disadvantage of these fire extinguishers is the fact that carbon dioxide evaporation negatively affect the respiratory tract, so their use in confined spaces is strictly prohibited.

Here is a list of advantages in comparison with the type OP, is as follows:

1. Carbon dioxide evaporates completely and at the same time does not leave any traces, which is good at putting out products such as computers and televisions other sophisticated electronics.

2. Using data extinguishers, fire extinguishing can be carried out up to 10 kV.

Summary and Conclusions

So, depending on the voltage class necessary to use such fire extinguishers:

- Up to 0.4 KV, powder, carbon dioxide. After the power failure and the foam water;

- Up to 1 kW is permissible to apply the powder, carbon dioxide;

- Up to 10 kV only carbon dioxide.

Attention. Know how to use fire extinguishers need. Remember one simple rule: if you see that the fire is already burning strongly enough, and disable the installation is not possible, then do not even try to extinguish the fire with fire extinguishers. After all, as there was no expensive equipment, human life is more expensive. Take care of yourself.
