When buying a fire extinguisher, many questions come to our minds. For example, what is the content of fire extinguishers? Are they going to protect me from hazards?

Different types and variety surely confuse some of us, not knowing which one is the most suitable. The first thing you need to do is understand what the content of fire extinguishers is. It is important to make sure you have the right fire extinguishers on hand to put on fires.
