ATEX explosive atmospheres must be designed and installed by a firm accredited by a notifying body

Since 2009, EcoTech has complied with the requirements of EN ISO 9001: 2008 and is accredited by INSEMEX to carry out activities in potentially explosive environments.
The experience gained during the works both in Romania and abroad has led to the development and improvement of industrial dusting systems, which also ensure the safety condition according to the European Directives.

European directives implementation in Romania through laws and standards are mandatory, and Schuko - Germany, helps us in their full realization. ATEX and CADES are implemented in Schuko plants. These laws and standards are mandatory in all production facilities in Europe.

Please note that the presence of ATEX components on the equipment does not convert that equipment into an ATEX certified product.
The road to having an ATEX certified product is long and costly, European traders have come to these products with these norms.
Romanian manufacturers of ATEX filters and equipment do not certify these products in accordance with ATEX94 / 9 and only self-certify.
Please note that ATEX94 / 9 explicitly specifies that for Zone 20 and 21 there is a Notified Body certification of all equipment, not just components.

Classification of areas with explosion hazard:

When we have an investment in air filtration, it's good to know:

  • Filtration plants are subject to European Norms EN 12779 and sometimes ATEX. To do this, the filter (inside of which zone 20 is located) must be certified by a "Notified Body".
  • These certificates are obtained only from European bodies (until this date INSEMEX is the only notifying body to ATEX or HG752)
  • The transport fan if working in the dust or sawdust area is notified for "zone 21 or 22"
  • Spray cabins are Zone 1 (requires certification);
  • The simple presence of the CE marking does not guarantee that the product is for zone 20. To do this, the specific markings mentioned above must be sought;
  • Often cheap solutions hide gaps that have huge costs;


European Parliament and Council Directive ATEX 1999/92 / EC [9] on minimum requirements for improving the protection of the health and safety of workers potentially at risk from exposure to explosive atmospheres (for equipment users).
The provisions of this Directive have been in force since July 2003 and set minimum requirements for the safety and health of operators who may be at risk of an explosive atmosphere. While the ATEX Directive 94/9 / EC obliges manufacturers to comply with the design and production requirements according to the classification of equipment and protective systems (which it covers in groups and categories of equipment), the ATEX Directive 1999/92 / EC obliges equipment users to evaluate hazards and classify hazardous areas while defining the categories and groups of protection systems and equipment to be used in each area.

The employer's main obligations are:

  • Prevention and protection against explosion by means of technical and organizational measures appropriate to the nature of the operation, taking into account, where appropriate, the basic principles (prevention of the formation of explosive environments, avoiding the burning of explosive environments and limiting the harmful effects of an explosion);
  • Explosion risk assessment taking into account at least the likelihood of explosive atmospheres being produced and maintained, the probability of sources of ignition, their activation and fire triggered, the installations, the substances used, the processes and their possible interactions, the magnitude of the anticipated effects;
  • Properly fitting the areas with explosion hazard;
  • Establishing the categories and protection systems and equipment to be used in each area;
  • Installation of materials (equipment) in accordance with Directive 94/9 / EC.

What is an explosive atmosphere?

An explosive atmosphere is built with a mixture of flammable gases, vapors, fog or dust in the atmosphere.
Factors for creating an explosion are:

  1. Air (or actually oxygen in the air)
  2. Flammable material (substance)
  3. Ignition source


What is INSEMEX?

The National Research and Development Institute for Mining Security and Anti-explosion Protection - INSEMEX Petroşani was founded in 1949 under the name of "Research Station for Mineral Security" as a subsidiary of I.C.E.M.I.N. Bucharest.

The institution is the only body in Romania that is accredited according to the law and provides scientific services for the attestation of technical installations operating in Ex areas, according to NEx 01-06 / 2007.
This standard applies to all technical installations intended to be used in potentially explosive atmospheres during the design, construction, operation and maintenance phases. By obtaining this attestation, EcoTech complements its expertise in safety, ensuring its customers the certainty of implementing exhaust systems that meet the requirements of potentially explosive atmospheres.
