When it comes to blow out fires in homes and offices, the first thing to use is the fire extinguisher filled with carbon dioxide (CO2). Fire extinguishers are not only handy things to put out fires, but they are a must have as per laws of many states but mostly for offices and public places.

It is a perception among many people that it costs a fortune to own a fire extinguisher. Well it may not be cheap to purchase one for the first time but it doesn’t need your jewelry to be sold. Having a fire extinguisher around when you are having wild parties can be more than a God sent help. There have been many incidents where barbecue parties turned out to be a disaster rather than a fun filled event. As most people are untrained or have zero experience to handle a grill filled with charcoals burning hot, they turn the entire place into a fireball within no time.

Fire extinguishers normally contain two things effective to put out fires. One type contains the H2O better known as water and the second type contains CO2 commonly known as carbon dioxide. Both of these are fitted with a liquid level indicator to let the owner know about the condition of the extinguisher. Every fire extinguisher has an expiry date and it can be confirmed through the gauge of the indicator on top of the extinguisher. Normally in public places such as the multi story buildings having plethora of offices, the management has appointed a special person whose duty is to check that all the fire extinguishers in the building are okay to be used. If any extinguisher is found to be going dry, it is reported to the concerned officials who send it for a refill.

In some cases the fire extinguisher may not have a gauge to show the pressure inside it. In this case the extinguisher may be hard to judge if it is fit for use or not. To manually check an extinguisher, the best device a person could use is the ultrasonic level indicator. Using this device the exact level of the liquid H2O or the gas CO2 can be determined. If the level is reported to be low, it obviously means that the extinguisher needs a refill desperately. It should be immediately sent to the refill company and placed back in the rightful location.
