Extract from DTU 45.1 – Food handling facilities N.B. : • The table is provided as a guide only, the classes must be appropriate to the controlled conditions of each facility. • A single parameter could justify the selection of ambient conditions (hygrometry, cleaning frequency, chemical aggressivity, salinity)
Aggressivity criteria
1 – No aggressive ambient conditions: environment presenting no aggressivity due to corrosive chemical components and/or microorganisms. 2 – Slightly aggressive ambient conditions: environment with no aggressive ambient conditions but whose walls could occasionally be splashed with slightly aggressive liquids. 3 – aggressive ambient conditions: environment where acid, basic or saline acid vapours occur and/or with presence of microorganisms and/or likely to be subjected to disinfection. 4 – very aggressive ambient conditions: environment where acid, base or saline acid vapours or gas occur and/or with presence of microorganisms and/or frequent risk of splashing of walls and/or likely to be subjected to disinfection with aggressive products.
