Inspection, service, and testing of foam fire-extinguishing systems must meet the requirements outlined in which NFPA standard?

The requirements for the inspection, service, and testing of foam fire-extinguishing systems are outlined in NFPA 25. This standard specifically addresses the inspection, testing, and maintenance of water-based fire protection systems, including foam systems. It provides guidelines to ensure that these systems operate effectively and reliably when needed. Compliance with NFPA 25 helps ensure that foam fire-extinguishing systems are properly maintained, contributing to the overall safety and effectiveness of fire protection measures.

Other standards mentioned do have relevant content but focus on different aspects of fire safety. NFPA 10 pertains to portable fire extinguishers, NFPA 20 discusses the installation of stationary pumps for fire protection, and NFPA 12 covers carbon dioxide extinguishing systems specifically. Thus, while all these standards are important in their respective areas, NFPA 25 is the correct reference for foam fire-extinguishing systems regarding inspection and testing requirements.
