Fire extinguishers are essential tools used to prevent, control and extinguish fires effectively.

The last category of fire extinguishers is the class b flammable type, which is classified as medium to high capacity. They are made from a combustible material and have sufficient storage space for storing two to five liters of liquid. They are most commonly used for power washing or wood destroying activities. They have an automatic re- ignition system, which allows users to press a button to initiate a fresh supply of oxygen.
