These extinguishers work by taking away the heat element off the fire triangle. For instance, foam agents work by separating the oxygen element from the other elements present in a fire scenario. These extinguishers re meant for Class A fires only. They must never be deployed on Class B or Class C fires. Know that the stream discharged from these systems can in fact end up spreading the flammable liquid in class B fires and lead to a shock hazard in class C fires.
Carbon Dioxide extinguishers Carbon Dioxide fire extinguishers put down the fire by the process of removing the oxygen and heat element from the fire triangle. This is achieved through a cold discharge. These extinguishers are highly effective on class B and Class C fires. They can never work well on class A fires.

No one wants to think that a fire will happen in their own home, but it does happen and more often than one would think. Most often it is accidental. I remember as a child a fire in my own home. My Dad had a deep fat fryer plugged in getting hot (my Mom is English, so had fish and chips for dinner every Saturday night). He was getting ready to go pick up my Mom from work, was distracted by a phone call and forgot to unplug the fryer before leaving. There were four of us kids at home when the kitchen caught fire. We were fine, there was a quick response from the fire department and damage was contained. We got to live at a hotel for six weeks, they had a swimming pool so it was cool for a 10 year old. But we were lucky. Cooking is the leading cause of home fires in the US and the leading cause of home fire injuries.Other causes of home fires include heating mishaps, tobacco products, and candles (there is a difference in the quality of candles!).  The last main reason for home fires is children playing with fire.  When fires strike a home, it is quick and devastating. So most personal things of importance in a home should be protected from fire.

One of the best ways to protect important family valuables and documents is with fire safes.  I was wondering what the difference was between a fireproof safe and a fire-resistant safe, and discovered that there is no such thing as a fireproof safe! Any material can suffer damage from heat and fire if exposed to a high enough temperature for a long enough time. But some materials are good at resisting extreme heat and fire for a limited period of time, so fire safes constructed with these material are designated as “fire resistant”.Average home fires peak at a temperature of 800 - 1200 degrees Fahrenheit (duration and peak temperature varies with size and construction material of home). Estimated time for firemen to get a home fire under control is 15 - 30 minutes. Since paper chars at 402°F, to protect important documents, a fire safes internal temperature needs to remain below 350°F. So at a minimum, a good fire resistant safe will keep the internal temperature below 350°F when exposed to a fire for 30 minutes that reaches a peak temperature of 1200°F. Fire safes undergo severe independent laboratory tests, being subjected to extremely hot fires for a specified period of time (either a 1 1/2 hour, 1 or 2 hours), and some to fire impact tests (simulating a safe being blown up or falling through burnt floor boards).
