Description: The technology of application of electrical equipment in explosive atmospheres is very old, dating almost from the original application of electricity to apparatus other than lighting. From its origins it has been developed in most industrialized countries with the United Kingdom, Germany and the United Sates of America being in the vanguard. As the world moves closer together this technology has, like all others, been coordinated so that its detail will be the same in all countries, principally to allow free marketing around the world. This has led to more detailed standard requirements particularly in the case of apparatus construction.
In addition, by developing practical examples of their use, it will assist in their application. This field is not one for inexperienced engineers and technologists and thus must be approached with care. In addition there are many local conditions which can vary the advice given here and those involved need to be aware of this and have sufficient expertise to determine conditions under which additional requirements are necessary and those, much less common, where relaxations are possible. The onus is, of course, always on the occupier of a location to be able to jus* what is done on safety grounds and it is hoped that this book will assist in this activity.
The contents here relate to the situation in the UK but differences in Europe and other counties are not great and its content should be useful elsewhere. Finally, unlike the situation historically existing, where this technology was often applied in isolation, it is now important to recognize that it can only be applied as a part of an overall safety strategy. That is not to say that its requirements can be ignored if they adversely affect other safety features but rather that, if such is the case, an alternative approach to achievement of its requirements should be sought. It should always be remembered that electrical installations in explosive atmospheres should only exist where necessary (i.e., where they can be fully justified).
