NFPA 13 Light Hazard Occupancy Fire Sprinkler Head Spacing

Summary The video from the YouTube channel "NFPA Joe" explains the concept of light hazard occupancy as defined by the National Fire Protection Association (NFPA) 13 standard. The video discusses the definition of light hazard occupancy, providing examples of occupancies that fall under this category, including offices, schools, and restaurants. It further clarifies that determining a specific occupancy's hazard level is the responsibility of the system designer, who must submit their plan to the local authority having jurisdiction for approval. The video then explores the practical application of this designation, demonstrating how light hazard occupancy affects the maximum spacing between fire sprinkler heads, the maximum coverage area each head can protect, and the minimum distance from walls.
