Choosing the right fire extinguisher


No one expects a break out of flames and yet every year fires cause significant damage to property and loss of life. Fires can quickly spread out of control if one isn’t adequately prepared and have fire suppression technology nearby.

It is important that fire extinguishers be used safely and effectively on a fire that the extinguisher was designed for. What you should also keep in mind when choosing a fire extinguisher, is knowing which extinguisher is suitable for which type of flammable situation.

There are fire extinguishers that can be used on A, B or C-class fire or a combination of the three fire classes. To choose the right fire extinguisher it is important to know about fire classes.
