In a commercial building, a kitchen hood is equipped with an automatic fire suppression system. The hood has a total exhaust flow rate of 10,000 cfm. According to the 2024 IFGC, what is the minimum outdoor air supply required for this hood?
- A500 CFM
- B1000 CFM
- 1500 CFM
- D2000 CFM
Exam tip
Ensure that you consider the total exhaust flow rate when determining the required outdoor air supply.
Why C is correct
The 2024 IFGC requires a minimum of 1 cfm per 100 cfm of exhaust air for kitchen hoods. For a 10,000 cfm hood, this translates to 100 cfm, which is rounded up to 1500 CFM.
