Expertise in explosion protection - Information andstandards The beginnings of explosion protection are to be found in the mining industry where miners are exposed to the dangers of fire damp. This term refers to methane gas which escapes in coal mines in particular and which reacts explosively when combined with fine coal dust and air (fire damp explosion). Explosive atmospheres may however occur in other branches of industry too, for example in the chemical or petrochemical industries. Electrical apparatus used in potentially explosive atmospheres must be constructed in such a way that it...

Expertise in explosion protection - Information andstandards ATEX With the ATEX product directive 2014/34/EU (ATEX 95) and the ATEX user directive 1999/92/EC (ATEX 137) the European Community has established the basis for uniform European explosion protection. This safety concept is applicable both for manufacturing electrical and non-electrical apparatus and for operating this apparatus in the respective industrial plants. The legislators of the individual member countries implement these directives in equivalent statutory regulations. In Germany for example these are the Explosion...

IECEx The international IECEx scheme also aims to assess conformity and certify apparatus, systems and services for use in explosive areas. The IECEx system, introduced in 1996, supports the standardisation of norms and the issuing of certi i ates of conformity (CoC) fc unrelated to specific countries or regions, in order to thus simplify the free global movement of goods. There is already extensive agree ment as to classes and require ments between the European ATEX directives and the IECEx regulations. This means that ATEX could one day be superseded. IECEx is of great importance outside...

Expertise in explosion protection – products and services Information and standards Physical and technical principles An explosion is a precipitate chemical reaction of combustible matter with oxygen setting free high energy. In this connection, combustible matter may be gases, mists, vapours or dusts. An explosion can only take place if three factors come together: combustible matter (in suitable dispersion and concentration), oxygen (in the air) and a source of ignition (e.g. an electric spark). It is thus necessary to prevent ignition or reduce the effect of an explosion to an innocuous...

Expertise in explosion protection – products and services Information and standards Duties and obligations of users in Europe ATEX directive 1999/92/EC defines users’ obligations for the protection of employees working in potentially explosive atmospheres. The user is obliged to establish technical and organisational measures to prevent explosions occurring. In this respect he must for example assess the potential danger and explosion risk, ensure that the working environ ment has been designed for safety and classify the hazardous areas into zones in accordance with the directives for safe...
