16. 1 - Pneumatic actuator suitability to installation place.
In case of use in areas with explosion danger, must be verified that the actuator is suitable to zone classification
and to inflammables peculiarity present on the plant.
Safety fundamental requirements against explosion risk into classified areas are fixed by European Directives
94/9/CE dated Mach 23, 1994 (for devices) and 1999/92/CE dated December 1999 (for plants).
16. 2 - Places with presence of gas, inflammable fogs, vapours and dusts.

factors:
- Plant type
- Zone classification: 0, 1, 2, 20, 21, 22 (for which are suitable devices respectively of category 1, 2, 3)
- Features of Inflammable substances present disguised as gases, vapours or fogs and layer of dust.
- Subgroup; IIA, IIB, IIC.
- Temperature class: T6 (defines gases ignition temperature)
- T (maximum superface temperature)
