How Safe Is Your Workspace?

Craig & Derricott ATEX Zone 22 Isolators

ATEX Zone 22 areas are those that are classified as a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air is not likely to occur in normal operation. If it does occur however, it would only be present for a short period of time. 

Traditionally, hazardous areas are thought of as those that have the presence of gases, mists or vapours present. There are a range of industries however where a conductive or non-conductive dust mixed in the right quantities can become explosive.
