ATEX consulting

ATEX is the conventional name for two European Union directives: 

  • 2014/34/EU, regulating the use of equipment in areas at risk of explosion. This directive is aimed at manufacturers of equipment for use in areas with potentially explosive atmospheres and imposes the obligation to certify these products; it repeals Directive 94/9/CE with effect from April 20, 2016; 
  • 99/92/CE on minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres. It applies to explosion-prone environments, where certified plants and equipment are deployed, and it is therefore aimed at users. 

The name comes from the words ATmosphères and EXplosibles. 

The 2014/34/EU Directive came into force 30 March 30, 2014 and repeals Directive 94/9/EC with effect from 20 April 2016; it mandates the ATEX certification for all products marketed in the EU, regardless of the place of production and the regulations in place, if they are installed in places at risk of explosion, with the exception of: 

  • medical equipment 
  • equipment and protective systems, when the risk of explosion is due solely to the presence of explosive materials or unstable chemicals; 
  • home appliances 
  • equipment for use in explosives production or storage locations 
  • embarked maritime, or in any case offshore equipment 
  • means of transport (excluding those for use in explosive atmospheres) 
  • equipment designed and built specifically for use by the armed forces or for law and public order enforcement. Dual-use devices are not excluded. 

In Italy, the implementation of the 2014/34/EU Directive took place through the enactment of the Legislative Decree of May 19, 2016, n. 85, replacing the D.P.R. 126 of 1998. ("Implementation of the 2014/34/EU Directive on harmonisation of Member States' legislation on protective equipment and systems intended for use in a potentially explosive atmosphere," which came into force on May 26, 2016).

Studio Tecnico Rossoni provides comprehensive assistance in the marking of equipment and protection systems intended to work in an explosive atmosphere, according to the ATEX Directive 2014/34/EU. Our services span from risk assessment in accordance with Essential Safety Requirements, to the preparation of the technical file and the manual of instructions, to the assistance during the entire certification process by the notified body. 
In particular, in agreement with the manufacturer we carry out: 

  • risk assessment in accordance with Essential Security Requirements - ESR leveraging established analysis methodologies; 
  • identification on the device of the potential trigger sources proposed by the UNI EN 1127-1 standard; 
  • verification of the effectiveness of the trigger sources in the machine according to the type of marking required; 
  • proposal of solutions for the elimination of effective trigger sources for igniting explosive atmospheres; 
  • preparation of the technical file of the equipment or protection system; 
  • drafting of the instruction manual of the machine; 
  • assistance throughout the marking process by the notified body 

The documentation is signed by a registered engineer and is in accordance with the ATEX 2014/34/EU Directive, which provides for classification according to Italian CEI EN 60079-10 rules and CEI 31-35 guidelines.
