Quick Answer
Recommended fire extinguisher types for garage lithium storage are Class B and Class D extinguishers, specifically designed to handle electrical fires and metal fires. --- Choosing the Right Fire Extinguisher When selecting a fire extinguisher for lithium storage in a garage, consider the type and size of the battery bank. Class B extinguishers are suitable for fires involving flammable liquids, such as those found in lithium-ion batteries. Look for an extinguisher rated at least 4A:80B:C, which can handle fires involving electrical appliances, flammable liquids, and combustible materials.
Extinguisher Inspection and Maintenance
Regularly inspect and maintain your fire extinguisher to ensure it remains functional and ready for use. Check the pressure gauge, hose, and nozzle for damage or wear. Every six months, perform a visual inspection, and annually have the extinguisher hydrostatically tested and recharge it if necessary. Keep in mind that fire extinguishers have a limited lifespan, typically 5-10 years, and should be replaced accordingly.
Proper Use of a Fire Extinguisher
In the event of a fire in your lithium storage area, follow the PASS method to use the extinguisher effectively: Pull the safety pin or ring, Aim the nozzle at the base of the fire, Squeeze the handle to release the extinguishing agent, and Sweep the nozzle back and forth to cover the entire area of the fire.
