Only commercial HVAC technicians and exhaust cleaning companies are allowed anywhere near restaurant vent systems.

Wrong. No such law.

[Erol Kartal]

No problem. I was only the warranty manager for a commercial cooking equipment service company for 7 years..

Never said it was a law. The exhaust ventilation of a kitchen is their life blood. Only trained, qualified personnel are allowed on a cook's line.

Allowed by whom? What does that have to do with inspections?

You tell me. You started the thread.

It is part of our Commercial Standards of Practice 6.5.12.

And no... no one can prohibit a buyer of commercial property from hiring an inspector, and certainly the cook can't.

Hey Nick,

The science of commercial kitchen ventilation includes both exhausting air as well as providing replacement air within the cooking area. Whether a restaurant is a small free-standing site or a large institutional kitchen, managing and balancing airflow is a complex issue. It is a challenge to properly ventilate commercial kitchens, as they require moving large volumes of air through ductwork and equipment placement in very restricted spaces.

Overall design, construction, installation coordination, and maintenance are required to get optimum performance and an energy-efficient air balance from the system.

SMACNA, through its technical manuals, provides the information and drawings to illustrate the elements of construction and installation of commercial kitchen exhaust hoods. The information is intended to encourage standardization in installations and to call attention to the appropriate segregation of responsibilities of those involved with food service design and installation.

Ducts accumulate combustible grease and should be constructed from 16- steel or 18-gage stainless steel as per code requirements.
In order for the exhaust system to work properly, make-up air is required to replace air equal to the amount removed. Make-up air can be provided via an independent system or in combination with the building's HVAC system.

Inspection of Exhaust Systems
In accordance with Section 11.3 of the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations (NFPA Standard 96):

When to Inspect? Who to Inspect?
"The entire exhaust system shall be inspected by a properly trained, qualified, and certified company or person(s) acceptable to the authority having jurisdiction in accordance with Table 11.3."

Table 11.3
Exhaust System Inspection Schedule

Type or Volume of Cooking Frequency
FrequencySystems serving solid fuel cooking operationsMonthly Systems serving high-volume cooking operations
- such as 24-hour cooking, charbroiling, or wok cookingQuarterly Systems serving moderate-volume cooking operationsSemiannuallySystems serving low-volume cooking operations

J. Inspect to determine that a portable fire extinguisher exists within a 30 foot travel distance of commercial-type cooking equipment that uses cooking oil or animal fat.

Did we forget the Ansul system instead of portable?




And here is a link to a typical checklist that might be useful.

Hope this helps some.

There is no way our average client is willing to pay us to perform a full NFPA 96 hood inspection. Besides, most of that would require operating and testing the hood and exhaust, something we can't do during a visual commercial property inspection.

[Marcel R. Cyr]

Nick, I am not saying that one has to do a full NFPA 96 inspection, I have just provided the information that can be added to supplement a visual that only consist of " appears grease is coming out of duct, fire extinguisher on wall, filters look or appear dirty, etc.

Was the hood mounted at standard height?
Is the exhaust duct made of steel or stainless?
How does one verify the gauge?
Was there a damper installed, that would be eligle?
Fire suppression systems are mandated in a lot of Jurisdictions.
Was one installed, and what was the date of the last inspection?

See, these are mostly all visuals also.

I would hate to report that the kitchen exhaust system is OK, and find out that the system failed in the following week.

That is a lot of responsibility to take.
If your type of visual is done, I would report it as such, that it was indeed a visual and in no way construes a fully inspected system.

Was the hood mounted at standard height? Code and 6.5.13.II.B and 3.1.
Is the exhaust duct made of steel or stainless? 6.5.13.I.D., so yes we check that.
How does one verify the gauge? 6.5.13.II.F.
Was there a damper installed, that would be eligle? Not required always.
Fire suppression systems are mandated in a lot of Jurisdictions. Not all jursdictions and not all appliances, hence 6.5.12.II.G. A fire extinguisher is in nearly all jurisdictions though, hence 6.5.13.I.K., so yes we check that.
Was one installed, and what was the date of the last inspection? 6.5.12.II.E., although you could request this from the owner in 5.3.1 as part of your request for documents.

[Marc D. Shunk]

I work on hood systems. Some of the inspectors (not NFPA 96 hood inspectors) take Schlieren photographs as an easy visual way determine if the exhaust and makeup air are working as intended. I put this in the same "value added" category as those who use IR cams for their home inspections.
