A good step to take when putting together a fire protection strategy is to plan out the possible locations of fire extinguishers, which are devices that can help slow or completely suppress the spread of a small fire. There are several classes of fire extinguishers available, each designed to handle a certain type of fire. You can tell extinguishers apart by the colored geometric symbol they have on the side.
Class A extinguishers might be the most common types you'd see in schools, office buildings, and other similar locations. These deal with normal, combustible materials like wood, paper, cardboard and plastic. This class of extinguisher has a green triangle on it.
If you need to try and suppress a fire with flammable or combustible liquids like oil, gas, or kerosene, you'd want to use a Class B extinguisher. This product uses a different type of material on the fire (sometimes CO2), since water would likely cause the fire to spread further. These have a red square on the side.
Fires involving appliances or other electrical equipment, such as wiring or breakers, will require the use of a Class C fire extinguisher. Because using water can put you at risk of electrical shock, a Class C product uses non-conductive materials like carbon dioxide. Some also use PKP, a dry chemical. These extinguishers are marked with a blue circle.
Fires containing combustible metals like magnesium, titanium, and sodium should be handled with a Class D extinguisher. These contain dry powder substances that can suppress such a fire, where other types might actually cause the fire to get worse. Do not confuse dry powder with dry chemical, like in Class C. You'll find a yellow decagon on the side of this device.
