Ventilation

Suitable and sufficient ventilation must be provided to produce a satisfactory, safe working environment and to reduce humidities and temperatures that would assist the rapid multiplication of bacteria. Ambient temperatures should be below 25OC. The ventilation system should always flow from a clean to a dirty area, must prevent excessive heat, condensation, dust and steam, and remove odours and contaminated air. Good ventilation will assist in reducing grease and staining of ceilings, so reducing the need for frequent decoration.

Steam producing equipment such as cookers, boilers and blanchers should be provided with adequately sized canopies. Canopies should overhang by around 250mm. Filters, should be cleaned frequently to eliminate fire hazards and maintain efficiency. Drainage gutters at the base of the canopies should be provided to collect condensate.
