When a kitchen is remodelled, what is typically required regarding fire protection?

• A. No changes required
• B. Remove WCFS entirely
• C. Increase duct size automatically
• D. Reassessment and possible modification of hood, duct, and WCFS to maintain coverage and compliance

Answer: (D)

Remodeling a kitchen can change where heat and grease loads occur, how air flows, and where fires could start. Because the hood, its ductwork, and the wet chemical fire suppression system are sized and arranged to protect specific appliances and areas, any significant change prompts a re-evaluation to make sure the protection still covers all surfaces and complies with current codes. You may need to adjust the hood or its mounting, reroute or resize the ducts, and modify or expand the WCFS so every cooking surface remains properly protected and the agent will reach the right places when discharged. After a remodel, the system should be re-rated and tested per NFPA requirements to confirm coverage and compliance. In short, reassessment and possible modification of the hood, duct, and WCFS are required to maintain proper protection.
