At all places where inflammable substances are produced, processed, transported or stored,safety is extremely important - especially in the chemical and petro chemical industry, in oil and natural gas production and in mining.In order to provide the highest level of safety possible, most states 'legislations' have developed corresponding conditions in the form of laws,regulations and standards. These now have to be implemented by companies because the operator of a plant is solely responsible for safe operation in accordance with the states health and safety policy. The area of responsibility there by extends to:
Stipulation of the explosive areas (zones),
Compilation of an explosion protection document,
Realisation of organisational and technical measures for explosionprotection,
Implementation of checks,
Use of products in Ex-areas that comply with the ATEX 95 directive.
Meaning of the zone classification
Zone 0/20: Danger is always present, for a long time or frequently
Zone 1/21: Danger is occasionally present
Zone 2/22: Danger is seldom present or present for a short time
