Fire extinguisher signs surely are vital tools that are especially useful during emergencies
Safety signs such as the fire extinguisher chart clearly delineate the different types of extinguishers as well as the classes of fire they are suitable to tackle. The different types of extinguishers include water, foam, powder, CO2 and wet chemical. Water is for class A fires. Foam can tackle class B, or those that involve flammable liquids. Multi-purpose powder fights off class A, B and E. Class E result from flammable gases. C02 is the only one safe to use for electrical fires. Lastly, wet chemical is for grease or cooking oil fires that are typically found in kitchens.
