Hazardous area classification drawings provide a road map that ensures that electrical/electronic equipment can be safely and properly specified and installed in hazardous (classified) locations such that the risk of fires or explosions is greatly reduced.

What are hazard zones?

Hazard zone means an area in which an explosive atmosphere is present, or may be expected to be present, in quantities such as to require special precautions for the construction, installation and use of potential ignition sources.

To ensure process safety, Hazardous area classification is of utmost importance.

  How is a hazardous area classified in Europe?

  In Europe and most of the world outside North America hazardous areas are classified with the Zone system – where Zones – defines the general nature (or properties) of the hazardous material – if its gas or dust, and the probability of the hazardous material in the surrounding atmosphere

  How are hazardous areas classified in the DSEAR?

  DSEAR specifically extends the original scope of this analysis, to take into account non-electrical sources of ignition, and mobile equipment that creates an ignition risk. Hazardous areas are classified into zones based on an assessment of the frequency of the occurrence and duration of an explosive gas atmosphere, as follows:
