NFPA 11C Summary

The NFPA 11C: Standard for Mobile Foam Apparatus (1999 edition), crafted by the National Fire Protection Agency (NFPA), stands as a pivotal reference point. It furnishes a comprehensive array of guidelines pertaining to the storage, handling, and utilization of flammable and combustible liquids, including waste liquids. This standard is tailored specifically for mobile foam apparatus, excluding hand-drawn equipment, designated for controlling and extinguishing fires involving flammable and combustible liquids in storage tanks and other areas susceptible to liquid spills. It is designed for individuals possessing the requisite expertise to design and install such equipment. NFPA 11C mandates thorough annual inspections and testing of all foam systems to ensure their proper operation and sustained functionality until the subsequent inspection. Additionally, it requires yearly inspections of foam concentrates and their storage containers to identify any signs of excessive sludging or deterioration. Samples of concentrates should undergo quality condition testing, either by the manufacturer or a qualified laboratory. While this 1999 edition lays down foundational guidelines, it's important to acknowledge that subsequent revisions have been undertaken to align with advancements in technology, industry practices, and safety research, reflecting the dynamic nature of fire protection standards.

What is the key differences between NFPA 11C, 1999 and its preceding version?

The current revision of NFPA 11C, titled "NFPA 11: 2021", comprehensively covers the design, installation, operation, testing, and maintenance of low-, medium-, and high-expansion foam systems for fire protection. These criteria are applicable to fixed, semi-fixed, or portable systems designed to mitigate both interior and exterior hazards.
