E2S Warning Signals have published a new ‘Guide for Hazardous areas’ which is available as a free download from their website. The guide has been put together with specifiers and hazardous area engineers in mind with matrix tables that enable fast cross-referencing of information between the main certification systems: ATEX, IECEx, North American and Canadian standards. Protection concepts are listed along with applicable zone, class or division and typical equipment protection level in an easy to read format.
