-
Cooking food on a large scale produces
greasy vapors that accumulate in the exhaust system. After a
period of time, the accumulation can become quite heavy.
-
This can produce a dangerous
situation. Cooking grease consists of almost pure unburned
hydrocarbons that can flash and burn. This type of fire burns very hot
and fast.
-
To prevent this we recommend
servicing your system every 90 days or more depending on the amount of
volume your restaurant does.
-
Our service is setup to remove the
accumulation that builds up in your system.
-
We use heavy duty degreasers,
superheated water and knowledge of the trade to completely
clean the entire system without leaving your kitchen a
disaster. *
HOW
OFTEN SHOULD A KITCHEN EXHAUST BE CLEANED?
- Wood-burning
or charcoal-burning stoves, char-broilers, 24-hour restaurants, and
some hamburger places: 30 DAYS.
- Many
hamburger restaurants and fast-food locations: 60 DAYS.
- Average
restaurant, employee cafeteria, and hotel or hospital kitchen: 90
DAYS.
- Pizza
places, convalescent hospital, small snack bar, oven hood: 180 DAYS.
- Hoods
over non-grease-creating appliances, such as steam kettles,
dishwashers, soup vats, etc. ONE YEAR.

Kitchen
exhaust cleaning is required by law for virtually every commercial
cooking establishment in the United States. Restaurants, hospitals,
hotels, employee cafeterias and other food-service locations have a
"hood" and ductwork over the stove to exhaust smoke, steam,
and fumes out of the building. These exhaust gases leave a residue on
the inside of the ductwork. This is usually a grease residue of some
sort, depending on the type of cooking. Char broilers commonly leave
heavy black grease.
Chinese
cooking normally deposits a sticky or rubbery residue. There will be
additional time needed to scrape and wash these type of KES (kitchen exhaust
systems) When a
charcoal or wood-burning stove is in use soot and ash residue builds up
in the ductwork. Dishwashers leave heavy lint deposits.
When the
buildup of grease becomes heavy, a fire hazard exists. Approximately one
of three restaurant fires is caused by grease. A common scenario of how
a kitchen exhaust fire starts is this:
A flame
flares up on the stove.
The fire
contacts the filters above the stove on the kitchen hood. The filters
ignite.
Since the
exhaust fan is on, drawing air into the hood, through the filters, and
up the duct, the flame on the filters is pulled into the duct.
If
significant grease residue exists on the duct interior, this can act as
a fuel and the fire spreads up the duct, perhaps all the way into the
fan. We have seen fire climb up a ten-story duct to the fan on the roof
and burn up the fan.
Modern
duct construction is designed to hopefully withstand such duct fires.
The duct seams are welded to prevent grease or fire from leaking out and
the shafts around the duct are made of fire- resistive materials.
However, older buildings are still at risk, and even in modern ones the
fire may leak out or could come out onto the roof via the fan.
When
an exhaust system is cleaned regularly, the chances of a duct fire are
extremely remote.
APPROVED METHODS OF CLEANING
There are two primary methods of cleaning
kitchen exhaust ductwork:
- Scraping.
- Pressure washing or steam cleaning.
The primary method used is scraping. This is
the more economical method and is extremely effective when done
thoroughly. We know of no duct fires that have occurred because of using
this method (unless it was done poorly). Scraping of duct systems complies
with the Uniform Fire Code. The cleaning method for kitchen exhausts
most often used by EnviroCleaners.Com is the Power Washing method.
The alternative to scraping is pressure
washing or steam cleaning. This is a more costly and time-consuming
technique, since it requires considerable prep work to control wastewater
and more expensive equipment is involved. However, this method will clean
ductwork down to "bare metal," which is the recommendation of
the National Fire Protection Association (N.F.P.A) as spelled out in
N.F.P.A Standard 96.
At EnviroCleaners.Com, we frequently do
pressure washing of kitchen exhausts as well as scraping. This is done for
a variety of reasons. Sometimes the ductwork may be inaccessible for
scraping . This is were we would install access panels shown in the
picture below as required by N.F.P.A 96.

The most common cleaning frequency is every 3
months. This can vary, however. The kitchen exhaust systems that need
cleaning most often are those over wood-burning or charcoal-burning
stoves. These should be cleaned every month at least, and in some cases as
often as every 2 weeks.
Below are various types of cooking
establishments and their most commonly recommended cleaning frequencies.
- Wood-burning
or charcoal-burning stoves, char-broilers, 24-hour restaurants, and
some hamburger places: 30 DAYS.
- Many
hamburger restaurants and fast-food locations: 60 DAYS.
- Average
restaurant, employee cafeteria, and hotel or hospital kitchen: 90
DAYS.
- Pizza
places, convalescent hospital, small snack bar, oven hood: 180 DAYS.
- Hoods
over non-grease-creating appliances, such as steam kettles,
dishwashers, soup vats, etc. ONE YEAR.
Kitchen exhaust cleaning is a standard part of
the routine maintenance of any cooking establishment. All kitchen managers
and restaurant owners should be aware of its role in fire prevention and
ensure it is done on a regular basis.
*Do
to systems varying from unit to unit, there are sometimes situations
that do not allow access to parts of the system and there for will
be labeled as "inaccessible areas for cleaning and
inspection". however all efforts will be taken to install
access panels for proper cleaning.
