Introduction
A Complete History Of ATEX: A Timeline
1785
One of the earliest recorded dust explosions occurred at Giacomelli's Bakery in Italy when a baker's boy shoveling flour under an open flame caused a flour cloud to ignite.
1815
Sir Humphry Davy invented the Davy lamp, a safety lamp with a wire mesh screen that enclosed the flame to prevent it from igniting flammable gases in coal mines. This was one of the first attempts at explosion protection.
Late 19th/Early 20th Century
Electric lighting was introduced in hazardous locations, offering advantages over flame-based lighting. Various protection methods were developed to prevent ignition from electrical sources, such as encapsulation, flameproofing, increased safety, and intrinsic safety.
1935
The first German standards, "Protection of Electrical Installations in Hazardous Areas", were published as guidelines for installing electrical equipment in hazardous areas.
1972-1973
A new set of European standards (EN 50014 - EN 50020) for equipment in explosive atmospheres was published by CENELEC, the European Committee for Electrotechnical Standardization. These were based on the IEC 60079-10 zone classification system.
1994
The ATEX Equipment Directive 94/9/EC (also known as ATEX 95 or ATEX 100a) was published, outlining requirements for equipment intended for use in potentially explosive atmospheres.
1999
The ATEX Workplace Directive 99/92/EC (also known as ATEX 137 or ATEX 118a) was published, specifying minimum requirements for improving the health and safety of workers potentially at risk from explosive atmospheres.
2014
The ATEX Equipment Directive was updated and recodified as 2014/34/EU. It replaced the 94/9/EC directive.

The Evolution of Explosion Protection Standards in Europe
The development of explosion protection standards in Europe has been closely tied to the coal mining industry and the inherent dangers posed by the presence of flammable gases, vapors, and dusts in coal mines. As countries like Belgium, France, the United Kingdom, and Germany heavily relied on coal during the Second Industrial Revolution, ensuring the safety of miners and equipment became a top priority.
Early Advancements in Explosion Protection
- 1815: Sir Humphry Davy invented the Davy lamp, a safety lamp with a wire mesh screen that enclosed the flame to prevent ignition of flammable gases in coal mines.
- 1870s: Electrical equipment began to be employed in coal mine shafts, leading to the development of flameproof enclosures.
- 1913: The Senghenydd Colliery disaster in South Wales led to the discovery of the intrinsically safe circuit concept.
Standardization Efforts in Germany and the United Kingdom
Germany and the United Kingdom played pivotal roles in the development of explosion protection standards. The German PTB (Physikalisch-Technische Bundesanstalt) and the VDE (Verband Deutscher Elektrotechniker) published the first set of standards and regulations for firedamp endangered mines in 1912 (VDE 0170) and guidelines for installing electrical systems in potentially explosive areas in 1935 (VDE 0165).
In the UK, the British Standards Institute published the first British standard for flameproof equipment (BS 229-1929) in 1929.
The Formation of ATEX Directives
As the European Community (EC) formed and aimed to facilitate trade between member states, the need for a common set of explosion protection standards became apparent. The standardization process, heavily influenced by the German DIN and British BSI standards, led to the creation of the CENELEC European Standards Organization in 1973 and the publication of the first directive for devices used in hazardous areas in 1975.
The ATEX Directives, derived from the French standard "Appareils destinés à être utilisés en ATmosphères EXplosives," were published in 1996 (94/9/EC - ATEX Equipment Directive) and 1999 (99/92/EC - ATEX Workplace Directive), becoming the rule of law in the EC. The latest update, 2014/34/EU, was published in 2014 by the European Parliament.
The Impact and Future of ATEX
The ATEX Directives have successfully removed barriers to trade within the European Union by providing a harmonized set of standards for explosion protection. The modular structure and focus on essential health and safety requirements have allowed for the adoption of innovative technologies while maintaining a high level of safety.
As the world continues to evolve, with increasing digitalization and political changes, the ATEX Directives will need to adapt to new challenges. However, their success in promoting international standardization serves as a model for future efforts in ensuring the safety of workers and equipment in potentially explosive atmospheres.
Conclusion: Protecting Lives and Assets in Hazardous Environments
The history of explosion protection standards in Europe, culminating in the development of the ATEX Directives, demonstrates the importance of collaboration and harmonization in ensuring the safety of workers and equipment in potentially explosive atmospheres. By learning from past incidents and building upon the knowledge and expertise of leading nations in the field, such as Germany and the United Kingdom, the European Union has established a comprehensive framework for explosion protection that serves as a model for the rest of the world.
