E2S Warning Signals have today 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, and 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.

In addition, the guide contains ample reference information related to
gas and dust atmospheres and potentially explosive environments, such as;

• Gas and dust groups and typical substances
  according to the main certification systems
  
• Maximum surface temperature of equipment,
  temperature classifications and ignition temperature limits of gas / dust
  
• Apparatus groups and typical ignition temperatures
  for common gases, vapours and dust
  
• Type of protection and basic concepts of protection
  listed by zone according to ATEX & IECEx and class and division according
  to US and Canadian standards
  
• IP ratings and NEMA enclosure types
  
• Typical equipment markings of hazardous area
  signalling products from the E2S portfolio
