Classification of Hazardous Areas
ATEX guidelines require the classification of hazardous areas into zones based on the frequency and duration of the presence of explosive atmospheres:
Zone 0, 20
An area where an explosive atmosphere is present continuously or for long periods.
Zone 1, 21
An area where an explosive atmosphere is likely to occur in normal operation.
Zone 2, 22
An area where an explosive atmosphere is not likely to occur in normal operation and, if it occurs, will persist for a short period only.
Proper classification is vital for selecting appropriate equipment and ensuring workplace safety.

Compliance and Certification
Manufacturers must ensure that their equipment complies with ATEX directives by:
CE Marking
Affixing the CE mark indicates that the product complies with the essential health and safety requirements of relevant EU directives. However, for ATEX compliance, additional certification and testing specific to the ATEX directive are required.
Declaration of Conformity
Providing documentation that certifies compliance with applicable standards.
Notified Bodies
In some cases, involving third-party organizations to assess conformity, especially for higher-risk equipment categories.
Compliance ensures the free movement of goods within the EU and adherence to safety standards.
