How must fire extinguishers be mounted as required by NFPA Standard 10?

Fire extinguishers must be mounted on a cabinet, rack, or hook as stipulated by NFPA Standard 10. This requirement ensures that extinguishers are readily accessible for immediate use in an emergency situation. Proper mounting allows for quick identification and retrieval, which is crucial during a fire when every second counts.

Mounting extinguishers on cabinets, racks, or hooks also minimizes risks associated with obstructions and ensures that they are visible and easy to reach. If extinguishers were mounted on the ground or in a storage closet, they might be more difficult to find or retrieve in a panic, leading to potential safety hazards. Furthermore, hanging from the ceiling is not practical as it would make access more difficult and could increase the chance of them being out of reach for most individuals. Therefore, the requirement for placement on a cabinet, rack, or hook aligns with safety protocols aimed at ensuring that fire extinguishers are effectively positioned for quick access in emergencies.
