Ex zones begin at 0 for gases and 20 for dust, while equipment classifications start at 1. The terms ‘ATEX zones’ and ‘ATEX equipment categories’ each have distinct origins and numbering systems, which we will explore further later in this article.

ATEX is the name commonly given to the two European directives for controlling explosive atmospheres. ATEX lifting equipment can mean electric chain hoists, wire rope hoists and belt hoists, winches, trolleys and pneumatic lifting equipment, and can be …

ATEX Zone 1 Definition – What is Zone 1? A Zone 1 hazardous area is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.

Mar 28, 2025 · ATEX Zone 1 equipment is essential for ensuring safety and compliance in environments with explosive gas risks. From communication to diagnostics, selecting the right certified gear prevents incidents and meets regulatory standards.

Oct 10, 2018 · ATEX and ex-proof classifications help manufacturers select and install equipment for potentially explosive atmospheres. ATEX is used in Europe, whereas Ex-Proof is used in North America and Canada. The process environment and properties of any materials that will be present need to be ascertained.

To comply with ATEX/IECEx regulations, all equipment and protective systems that are used in hazardous areas must be marked legibly and indelibly with a specific set of letters/numbers.

The first ATEX directive (94/9/EC) addresses requirements of equipment used in areas where there is a danger of explosion. Manufacturers must fulfill the directive requirements in their instrument design and mark the products with the relevant approval.

ATEX (ATmosphere EXplosible) refers to two EU directives about danger of explosion within different areas. The ATEX Directive is a critical regulatory framework for ensuring safety in environments where explosive atmospheres are a risk.
