FIR-8.08 - Cleaning of Commercial Cooking Hood and Ventilation Systems

CLEANING OF COMMERCIAL COOKING HOOD AND VENTILATION SYSTEMS
Administrative Rule Adopted by Portland Fire & Rescue Pursuant to Rule-Making Authority
ARB-FIR-8.08
PURPOSE:
To establish guidelines for the cleaning of hoods, grease removal devices, fans, ducts, and exhausting grease laden vapors.
SCOPE: This policy applies to all existing structures where Portland Fire & Rescue has authority.

BACKGROUND:
The 1994 Edition of the Uniform Fire Code, as adopted by the City of Portland, states "The Chief is authorized to administer and enforce this Code. Under the Chief's direction, the Fire Department is authorized to enforce all ordinances of the jurisdiction pertaining to: 1006.2.8 "Operation and Maintenance of Ventilation Systems."
During the early part of 1998, Portland experienced several greater alarm fires. These fires were the result of commercial cooking hood and ventilation system failures. At that time, a task force was assembled consisting of members from the Fire Bureau, the cleaning industry, chimney sweeps, the restaurant association, the insurance industry, and the Bureau of Buildings. This policy is the result of the Task Force Team's Action Plan.
