ZONE CLASSIFICATION SUMMARY
The primary activity for Area Classification is to list the
process equipment in the area under consideration and
identify all potential sources of flammable material. An
estimate must be made of the duration and frequency of
each release in order to classify the emission as
Continuous, Primary or Secondary and the rate of
potentially explosive atmosphere into the surrounding
area.
Note: Hazardous area classification due to flammable gases, vapours or mists only
