NFPA 10

NFPA 10, issued by the National Fire Protection Association, is the standard for portable fire extinguishers and provides requirements for their selection, installation, inspection, maintenance, and use. The standard ensures that appropriate types of extinguishers are provided based on fire classifications such as Class A (ordinary combustibles), Class B (flammable liquids), Class C (electrical), Class D (metals), and Class K (cooking oils and fats). It specifies proper placement to ensure accessibility, visibility, and adequate travel distance, as well as mounting heights and signage. NFPA 10 also defines routine inspection requirements, typically monthly visual checks and annual maintenance by qualified personnel, along with periodic hydrostatic testing. Additionally, it emphasizes user training to ensure personnel can safely and effectively operate extinguishers during the early stages of a fire. Overall, NFPA 10 is critical for ensuring that portable fire extinguishers are ready for use, properly maintained, and capable of controlling incipient-stage fires, thereby supporting workplace safety and emergency response.
