Preventive Fire carries a full line of new commercial-grade fire extinguishers and fire extinguisher services. We inspect service, recharge, and repair all types of portable fire extinguishers. Preventive Fire carries the three main types of fire extinguisher brackets covering from simple wall mounts, medium-grade vehicle brackets, up to heavy-duty vehicle brackets.
Extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics.
Fires involving flammable or combustible liquids such as gasoline, kerosene, grease, and oil. The numerical rating for class B extinguishers indicates the approximate number of square feet of fire it can extinguish.
Fires involve electrical equipment, such as appliances, wiring, circuit breakers, and outlets. Never use water to extinguish class C fires – the risk of electrical shock is far too great! Class C extinguishers do not have a numerical rating. The C classification means the extinguishing agent is non-conductive.
Fire extinguishers are commonly found in a Machine Shop. They are for fires that involve combustible metals, such as magnesium, titanium, potassium, and sodium. These types of extinguishers also have no numerical rating, nor are they given a multi-purpose rating – they are designed for class D fires only.
Fire extinguishers are for fires that involve cooking oils, trans-fats, or fats in cooking appliances and are typically found in restaurant and cafeteria kitchens. Geometric symbol
