Commercial Kitchen Ventilation & Fire Protection

Practical interpretations, field tips, and real-world stories — not a copy of the standard.

What NFPA 96 covers — the whole commercial kitchen fire-protection package

The verified edition chain — this is where 17A-2009 comes from

The vocabulary that decides what needs a hood

The rules that apply to the whole system — clearances, drawings, AHJ notice

The capture device — construction, size, and listed assemblies

Filters and extractors — the first line of grease defense

The grease duct — welded tight, accessible, and nothing else inside it

Fans and makeup air — the system only works when air actually moves

What is NOT allowed inside the grease exhaust stream

The requirement chapter — what protection a kitchen must have

THE ITM chapter — the semiannual rule, link replacement, cleaning frequencies (2021/2024 editions: this is Chapter 12)

The appliances themselves — listings and operating controls

Ductless hoods — allowed only inside tight listing limits

Wood and charcoal cooking — sparks, embers, creosote, and monthly inspections
