Many commercial cooking establishments have grease extraction or control devices downstream of the hood to remove grease and odors from the effluent stream. Where are most of these devices installed?

1. On the rooftop immediately before the fan

2. Under the cooking area

3. In the basement

4. Inside the hood

The correct answer is: On the rooftop immediately before the fan

In many commercial cooking establishments, grease extraction or control devices are typically installed on the rooftop immediately before the fan. This placement is strategic for several reasons. Firstly, positioning these devices on the rooftop allows for the effective removal of both grease and odors from the kitchen effluent before they enter the ventilation system. By placing them before the fan, any airborne contaminants can be filtered out, reducing the risk of grease buildup in the ductwork, which is a significant fire hazard. Additionally, rooftop installations often provide better access for maintenance and cleaning. This is crucial in environments where grease accumulation must be regularly managed to ensure operational safety and compliance with local fire codes. Proper maintenance of these devices is essential for their effectiveness in fire prevention strategies. In contrast, placing them under the cooking area, in the basement, or inside the hood could lead to numerous operational challenges, including reduced efficiency in grease removal, increased fire risks from grease-laden vapors remaining in the system, and greater difficulty in performing maintenance tasks.
