What are the characteristics of Class I fire extinguishers?

Fire Extinguisher Valves are very important part of fire safety equipment. These are used to control the spread of flames in confined spaces like the kitchen, work place or the attic. These can also be used to extinguish flames in open spaces like a big garden, courtyard or any open space where there are inflammable materials.

The handles are made of rubber and have a metal frame with a spring mechanism to enable easy control. The body is made up of nylon and has an opening for the release of the fuel and the cover is made of polypropylene. The price of each type depends upon the weight and the size.
