Legionellosis risk at schools: how to prevent it?

Legionellosis often represents a not considered risk in biological risk evaluation of schools, but epidemics have been discovered in environments like schools, hotels and hospitals

Hazards

Eliminating greasy, charred and viscous deposits reduces the risk of fire in extractor hoods and intake ducts for aspiration of unburnt fumes, improving the performance and the duration of the suction motors.


Extractor hoods and intake ducts for aspiration of unburnt fumes used in canteen, hotel, restaurant and communal kitchens, are liable to the formation of greasy, charred or viscous deposits. The nature itself of such deposits, with their high calorie lipid components, together with the very high temperatures reached inside the extractor system; facilitate the combustion process causing a high risk of fire in the apparatus.

The strong adhesiveness and consistency of the deposits make them able to compromise the regular working order of the system, clogging them up and altering their draught. Furthermore, the lifespan of the suction motors greatly diminishes.

The deposits found inside the hoods at most constitute an organic substratum which is suitable for microbiological proliferation: for this purpose a swift, effective and safe cleaning system should be adopted.

The different components of the extractor system have different characteristics and various problems to solve.

  • Extractor fan

    The sediments found on the internal surfaces of the entrance to the extractor, due to their high calorie lipid components, facilitate the combustion process, causing a high risk of fire in the apparatus;

  • Intake ducts

    Intake ducts and sensitive joints are the most problematic parts in the removal of lipid deposits. Video inspection makes it possible to evaluate where to intervene and which technique to use to do this in the best possible manner, even in the most critical points;

  • Extractor unit

    The fans and the extractor motor require periodic maintenance and precise cleaning as greasy deposits impair their proper functioning.


Primagire to protect

To guarantee hygiene, avoid food contamination and eliminate the risks of equipment failure.

The consequences of poor maintenance of intake ducts for aspiration of unburnt fumes remarkably increases the risk of fire, because malfunctioning and lead to a problematic state of hygiene.

The solution to these problems is summarised in a single word: Primagire.
To intervene pre-emptively and eliminate the fire risk and equipment failure due to the presence of greasy, charred or viscous deposits. Primagire to guarantee hygiene and not food contamination.
