Commercial Kitchen Grease Fire Prevention and Hood Cleaning
Regular inspection, cleaning and maintenance of the commercial cooking exhaust system are important parts of kitchen fire prevention.
Grease moves beyond the visible hood
Airborne grease can collect behind filters, in plenums and ducts, at fans and around rooftop discharge areas. A shiny exterior does not prove the full system is clean.
Inspection and cleaning intervals matter
Follow current Massachusetts requirements and the findings of qualified inspections. High-volume and solid-fuel operations commonly need closer attention.
Do not ignore access
If duct sections cannot be reached, the limitation should be documented and proper access evaluated.
Coordinate related systems
Fire-suppression inspection, cooking-equipment maintenance, fan repairs and building fire protection are separate responsibilities that should remain current.
Train staff on daily warning signs
Managers should notice smoke capture problems, grease drips, unusual fan noise, damaged filters, missing labels and overdue service dates.

Frequently asked questions
Does hood cleaning eliminate all fire risk?
No. It reduces grease accumulation in the serviced exhaust areas, but commercial kitchen fire safety also depends on equipment, suppression, operations and building systems.
Can staff clean the duct themselves?
Regulated commercial exhaust cleaning and inspection in Massachusetts must be performed by properly credentialed people.
What should happen after a grease fire?
Follow emergency and fire-department instructions. Do not reopen or use equipment until the appropriate authorities and qualified professionals approve the next steps.
