For most cars and light trucks in Los Angeles, a 2.5 lb or 5 lb ABC extinguisher in a secure vehicle bracket (such as the Amerex B417T or B402) is the right fit. Commercial motor vehicles must carry at least a 5 B:C rated unit under federal FMCSA rules. In a vehicle fire, get everyone out first. Use the extinguisher only on a small, early fire, and never fully open a burning hood.
Most Los Angeles warehouses should standardize on 20 lb ABC extinguishers (such as the Amerex A411 or 423, rated 10A:120B:C). Mount them so no one walks more than 75 feet to reach one, as NFPA 10 requires for ordinary hazards. Add Purple K near flammable liquids and forklift fueling, and wheeled units for docks and yards. Inspect them monthly and have a licensed California concern service them every year.
A lithium-ion battery energy storage system (BESS) needs an engineered fire protection design reviewed by the local fire authority. Portable extinguishers don’t replace that. They protect the rooms around the batteries. For LA County facilities, that usually means clean agent (Halotron I) or CO₂ units in electrical and control rooms, 20 lb ABC units in general areas, and wheeled units in yards. If a battery module is burning, evacuate and call 911.
Keep at least one UL-listed ABC multipurpose extinguisher, such as the Amerex B500 5 lb, in every Los Angeles home or apartment, mounted near the kitchen exit and near where e-bikes, scooters or tools charge. If a lithium-ion battery itself is venting or burning, get everyone out and call 911. A portable extinguisher can control nearby flames, but it cannot stop a battery in thermal runaway.
