Cleaning Requirement/Schedule for Type II Hood?

[swhipple]

Hello All,

During recent inspections at several community facilities in my area of Virginia, it was discovered a fire protection company was inspecting and cleaning some Type 2 hoods for commercial dishwashers and not others. My questions to those of you out there are "Have you ever encountered this?" and "Is there a requirement that they be cleaned regularly?" These hoods would, of course, be used to exhaust condensate or steam. My research so far has led me to the conclusion that there is not. Thanks for any insight you can provide.

I have never seen a requirement for cleaning such hoods from a Fire Protection perspective.
There are such requirements for commercial cooking appliances (NFPA 96) which specify service hatches on ducts and cleaning intervals, but I hardly believe that this applies to dishwashers.
