Kitchen exhaust hood cleaning in Panama restaurants: how often, according to NFPA 96

How often, according to NFPA 96

Table 11.4 of NFPA 96 sorts exhaust systems by type of cooking and assigns an inspection interval for grease buildup. An insurer’s guide from Markel and an information sheet from the New York village of New Paltz on the 2017 edition agree on the four levels in the table.

The table sets when to look at the system. Cleaning is decided by the result: according to the New Paltz sheet, if the inspection finds deposits from grease-laden vapors, the contaminated parts are cleaned, and the work must be done by a trained and certified company or person. The texts cited are summaries of the standard; the full text of NFPA 96 is paid, and the table could only be confirmed through them.

What NFPA 96 is and what it covers

NFPA 96 is the standard of the National Fire Protection Association titled Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations. In practice it covers hoods, grease filters, ducts and exhaust fans: how they are installed, how they are inspected and how often they are cleaned.

It is a consensus standard developed by a committee and revised periodically, as its development page indicates. For that reason it helps to check which edition the jurisdiction adopted: the 2017 text summarized by New Paltz may differ from later editions.

The New Paltz sheet summarizes other requirements of the 2017 edition: access panels so that the whole hood and duct can be cleaned, and cleaning before surfaces become heavily coated with grease or oily sludge. They help show the scope, although they are not the text of the standard.

Why grease is a fire risk

Cooking is the most common origin of restaurant fires. The U.S. Fire Administration (USFA) summary on restaurant fires, with data from 2011 to 2013, says cooking was by far the leading cause and accounted for 64% of restaurant fires, with about 5,600 reported to fire departments each year. That page does not break out grease or ducts.

The same agency says, on its page on nonresidential building fire causes, that cooking was the leading cause over the ten years from 2014 to 2023, with an estimated 33,300 fires in 2023. The figure covers the whole nonresidential sector, not only restaurants.

The Climatiza Panamá restaurant page states that grease built up in ducts is, in the site’s words, the most serious fire risk in a restaurant. It is a claim by the company, not a figure from the agencies cited.

What applies in Panama

The review done for this guide did not turn up a published rule from Panama’s fire department (Cuerpo de Bomberos) or the Gaceta Oficial adopting NFPA 96 for commercial kitchen hoods and ducts. For that reason this article does not claim the table is mandatory by law in the country.

What can be said is that NFPA 96 is the international reference used by insurers and service providers. Climatiza Panamá describes it on its duct and kitchen hood cleaning page as a reference standard and repeats the same four intervals. The specific requirements for each restaurant (fire inspection, insurer conditions, building rules) are best checked with the Benemérito Cuerpo de Bomberos de Panamá, the insurer and the building administration.

Climatiza adds, on its own page, that almost no commercial kitchen in Panama operates fewer than twelve months a year, so treating a kitchen as moderate volume seems optimistic to the company. That is the company’s view, not an official figure.

How a cleaning is documented

According to New Paltz’s summary of the 2017 edition of NFPA 96, when a system is inspected or cleaned, a certificate with the company name, the name of the person who did the work and the date must be kept on the premises, plus a label on the hood showing the next inspection or cleaning date. The New York City fire department, in its guide for commercial kitchens (in Spanish), also shows a label placed on the fan after service and recommends requiring the duct to be cleaned all the way to bare metal.

Climatiza Panamá describes on its page the process it follows: a camera inspection with photos of the initial state, a second inspection with photos of the final state, and a written report with the date, scope and personnel who did the work, plus a record of sections that could not be reached. The company says the record is useful for insurers and inspections. Its description does not mention a certificate under that name; the document is the report.

How to decide a restaurant’s frequency

The table gives an inspection interval by type of cooking, and Climatiza Panamá argues on its restaurant page that in Panama the real frequency tends to be higher than assumed and that manual intervals should be shortened. That is the company’s opinion. A reasonable order for deciding:

For operators with several locations, the restaurant page of Climatiza Panamá mentions an asset survey and a single calendar with reports per location. The website gives no further detail on scope.

Myths and facts

• Myth: cleaning the filter is enough. Fact: the standard looks at the whole system, with hood, duct and fan; the New Paltz sheet speaks of inspecting the entire exhaust system.
• Myth: the table sets a mandatory cleaning at that frequency. Fact: the table sets inspection; cleaning depends on what that inspection finds.
• Myth: NFPA 96 is law in Panama. Fact: no published Panamanian rule adopting it for hoods was found. It is an international reference.
• Myth: a small restaurant is always low volume. Fact: the classification depends on the type and intensity of cooking, not the size of the premises.
• Myth: if it does not smell, there is no grease. Fact: odor is a sign, but grease can build up in duct sections not visible from the kitchen; a camera inspection provides evidence.
• Myth: a partial cleaning equals a full one. Fact: without access points some sections stay uncleaned, and the report should say so.
