Your fire extinguisher is your first line of defense against fire. The saying of “it is better to have one and not need it, than need it but you have none” is indeed the best thing when your fire extinguisher is surely functional.
Most of the dry chemical powder contains mono-ammonium phosphate and has the capability to extinguish class A (for control of class A with fire source: paper, wood, etc.), class B (fire source: gasoline, oil, etc.) and class C (fire source: usually in electrical) fire incidents. When the chemical contacts fire, it gets fused while absorbing flame heat and decomposes to form a glassy, non-flammable film that covers the flame and deprive it of the air, thereby contain or kill the fire.
The cylinder is either a pressurized one or a cartridge type. Pressurized type is most common because a gauge is displayed on the neck of the cylinder that indicates its operating pressure, while the cartridge type has a special cartridge used for discharging the contents.
Inspection on these types of fire extinguisher should be done periodically especially when the units are exposed to elements that can cause defects. For the pressurized type, the pressure gauge should indicate operating pressure such as the pointer is on the “charge” status. If the gauge pointer is on the “discharge”, pull this unit out and notify your service maintenance for the reconditioning or recharging. Make sure that the gauge is operational. Furthermore, check for the safety pin, lever, hose and some features of corrosion. It is a practice by firefighters to allow the content to be stirred by shaking the cylinder to avoid chemical “caking”. Cartridge type is checked by the specific weight of the cartridge. Through this inspection method, it will assure that the pressure is still reliable. For this type of fire extinguisher cylinder, a nozzle is attached to the discharge hose, which requires inspection for wear and tear, and that they are not blocked.
For Carbon Dioxide (CO2) type fire extinguishers, it is obviously seen that a horn is attached to the hose. This type is supposed to be stationed or posted to a well-ventilated and / or low temperature room because this type is pressurized with Carbon dioxide gas which is a non-conductive and non-corrosive gas.It is taken out from the atmosphere and stored at high pressure in the liquid state within a cylinder. The basic use of this type reduces the amount of oxygen available to the fire.
Make sure that you do not neglect the inspection of your fire extinguisher especially on a house for sale because this safety device can save your life one day. You have to be certain that it is kept in good condition for it to be able to serve its purpose effectively. It is highly recommended by narrow lot home designs Perth, since a fire on such confined space is extremely treacherous.
