A Type II hood is a kitchen hood used for the collection of ____.

• A. Products of combustion
• B. Grease laden vapors
• C. Fumes and odors, steam or heat
• D. Products of combustion and fumes and odors, steam or heat

Answer: (D)

The idea being tested is how kitchen hoods are classified by what they collect. Type II hoods are designed for non-grease-producing operations and are intended to capture contaminants like heat, steam, fumes, and odors. In many systems, they may also handle combustion byproducts from appliances that burn fuel, so the most complete description of what such a hood collects includes combustion products as well as fumes, odors, steam, and heat. That makes the option describing all of these the best fit. The other descriptions don’t fit as well: grease-laden vapors are the domain of Type I hoods, which are specifically for grease and smoke; just fumes and odors, steam or heat covers part of what a Type II hood handles but omits combustion products; and listing only products of combustion is incomplete because Type II hoods also address odors, steam, and heat.
