Summary

Ammonia has been considered to be an excellent choice of refrigerant for industrial applications for over 150 years. However, ammonia is toxic and besides it is also flammable and requires careful safety consideration in the design and operation of refrigeration systems, even though it has a good safety record and ignition of ammonia is a very rare occurrence and is virtually unknown in systems which comply with recognized European Standards. In the UK a recent ‘Joint Industry Project’ has sought to provide practical guidance to ensure ammonia refrigeration plants are fully compliant with the Dangerous Substances and Explosive Atmospheres Regulations 2002 as required by EU ATEX Directives. This paper provides an overview of the current legal framework and explains the procedure to be followed in classification of hazardous areas in accordance with IEC EN 60079-10-1. Finally an approach using new software to model potential releases and calculate the hazard range, is described.
