What should be done with abandoned pipe or conduit from previous installations in hoods and ducts?

Abandoned pipe or conduit from previous installations in hoods and ducts must be removed to ensure safety and compliance with the NFPA 96 standards. Retaining such materials can create unnecessary fire hazards by providing potential paths for grease accumulation and limiting the effectiveness of the ventilation system. Furthermore, abandoned structures may not be accessible for cleaning, which is crucial for fire prevention in cooking operations.

Removing these items helps maintain a clean environment that supports proper airflow and minimizes the risk of fire due to grease build-up or mechanical failure. This proactive measure aligns with the overall goal of NFPA 96 to optimize fire safety in commercial cooking settings, thereby protecting life and property.
