Which NFPA Standard covers Hoods and Ducts?

• A. NFPA 101
• B. NFPA 70
• C. NFPA 1
• D. NFPA 96

Answer: (D)

Hoods and ducts are covered by a standard that focuses on ventilation control and fire protection for commercial cooking operations. This standard specifies the design, installation, operation, inspection, testing, and maintenance of kitchen ventilation systems, including the hood, grease filtration, exhaust ducts, and the fire suppression system that may be integrated with the hood. It also addresses grease buildup, duct cleaning frequencies, clearance requirements, and materials compatibility to minimize ignition risk and ensure safe exhaust of cooking fumes.

Other NFPA standards address different topics: the Life Safety Code concentrates on occupant safety and means of egress; the National Electrical Code covers electrical installations; and the Fire Code provides general fire provisions but does not delve into the specific requirements for kitchen hoods and ducts. Thus, the standard that covers hoods and ducts is NFPA 96.
