Safety In The Kitchen

Cleaning of the extraction canopy is essential on both hygiene and fire safety grounds. Although a greasy extraction canopy may not increase the risk of food poisoning, the greasy deposits and build-up inside an extraction canopy is a great breeding ground for all types of bacteria.

The contaminated grease may drip from the canopy, and contaminate food and utensils. Regular cleaning to ensure that no dripping grease is present will minimise this risk.

In addition, the extraction canopy is a very real fire hazard. Some 70% of kitchen fires originate in the extraction canopy and associated ductwork. In kitchens, a good ventilation system will remove heat and grease coming off cooking equipment and will also remove dangerous carbon monoxide gases from the combustion of gas cooking.

Grease that builds up in the extraction canopy is easily ignited. A small flame from flambéing or flame-grilling could easily ignite and
have disastrous consequences. Kitchens have been known to ignite even after shut down due to the heat from the cooling cooking equipment.

Cleaning of the extraction canopy is therefore essential on both hygiene and fire safety grounds.

Thus, there is a national standard (SANS 1850) covering kitchen exhaust systems and its requirements are generally beyond the scope of in-house stewarding and maintenance staff.
