Why Your Fire Sprinkler Heads in Exhaust Ducts Should be Inspected Periodically.

Fire sprinkler heads in exhaust ducts should be inspected periodically.

An annual inspection is required to check fire sprinkler heads in kitchen hoods and exhaust ducts for an excessive accumulation of grease; any foreign matter; or for other damage. Inspectors should check these spots to determine whether it is necessary to replace the sprinkler head.

Cooking equipment, kitchen hoods and associated ventilation systems (including exhaust ducts) are all required to be fitted with a fire sprinkler system designed to Australian Standard AS 2118.1 and installed in accordance with the National Construction Code.

Unfortunately over time, kitchen hoods and exhaust ducts accumulate oil, grease and other byproducts of cooking in kitchens. This accumulation can lead to a fire and promote the spread of fire through a building. An automatic fire sprinkler system is installed in kitchen hoods and ducts to protect these locations from a fire or help prevent the spread of fire through a building.

When you next enter your kitchen or place where you cook, take a look around at your hood or exhaust duct – if it has an automatic fire sprinkler system installed in accordance with AS 2118.1, then it will have an identification plate attached to it stating this fact.

Where you are they required to be installed?

AS 2118.1, which requires sprinkler heads to be installed at specific locations; under kitchen hoods, not more than 3.6 meters apart; and in horizontal ducts 4 meters apart; or at the head of a vertical rising duct.

Where the cooking equipment includes a deep fat fryer, there are other considerations that installers and maintainers MUST take into consideration:

– The fire area must be kept clear of combustible materials such as curtains or paper products. This helps prevent fires from spreading easily throughout the kitchen space.

– The opening of exit doors leading directly outside should be protected by a self-closing device. This ensures that the door cannot be left open during operation of machinery or cooking equipment that generates heat or sparks (like gas burners).

– The location of fire extinguishers should also be considered—they should be placed in areas where they can easily be accessed by staff members who may need them in case of emergency situations

As per AS 1851 in Table, fire sprinkler heads in exhaust ducts must be inspected and maintained as described below.

 In order to ensure the safety of your kitchen, it is important that automatic fire sprinkler heads are regularly inspected by a professional inspector. They should be inspected once a year, or every time there is significant damage or maintenance done to the system.

The inspector will look for several things:

-Excessive accumulation of contaminants such as grease

-Physical damage to the frangible element or deflector

-Incorrect sprinkler head response time index

-Missing or damaged mechanical protection

-No access for inspection

Fire sprinklers are an integral part of the fire protection required for commercial kitchens. The kitchen is one of those areas where fire can spread very quickly. Fire sprinklers are the most economical and efficient means of suppressing fires. Because of their importance in commercial cooking, it is essential that they are inspected by a qualified professional on a regular basis to make sure they work as they should do so when a fire breaks out they will have the intended effect.
