ATEX

Producers must attach the utmost importance to “process safety” which is a critical process regulated by directives such as SEVESO and ATEX.

(ATEX  137 [99/92/EC] – Directive on Protection of Workers from Risks of Explosive Atmospheres)

ATEX 137 directive lays out the minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres. The organizations where explosive atmospheres may arise must meet the requirements of this directive and ensure the health and safety of the workers.

Safety inspection based on ATEX 137 directive covers a detailed assessment of the organization where explosive atmospheres may arise. A conformity report based on ATEX 137 is drawn up for organizations if conformity is confirmed. This report shows the organization has taken all preventive measures for workers in the explosive atmospheres.

According to the requirement set by the “Directive on Protection of Workers Potentially at Risk from Explosive Atmospheres” published in the Oficial Gazette on April 30, 2013, no. 28633, all firms where potentially explosive atmospheres are likely to be present, are obliged to prepare an “Explosion Protection Document”.

According to the Directive, in all areas where flammable and explosive chemicals are present, it is required to draw a ZONE mapping.

As SZUTEST, we carry out the following activities in the scope of the Explosion Protection Document (PKD):

  • Examination of all MSDS forms (Material Safety Information Sheets) in the establishment and identification of flammable and explosive chemicals,
  • Making the Zone calculations for the identified chemicals based on the EN 60079-10-1, EN 60079-10-2 and CEI 31-35 standards,
  • Drawing the Zone maps and preparing the Explosion Protection Document,
  • If requested, we have Exproof equipment conformity service as well for the equipment in the Zones.

(EN 60079-10-1 – Explosive Atmospheres- Part 10-1: Classification of areas – Explosive gas atmospheres)

Equipment used in explosive gas atmospheres are ex-proof and in special designs. Selection of these equipment is made based on the hazardous zone classification of the organization. Therefore, organizations where explosive atmospheres may arise, must have a hazardous zone mapping.

Design-project inspections and hazardous zone classifications are covered in EN 60079-10-1 standard in detail. A design-project report based on EN 60079-10-1 is drawn up for the organizations, and this report includes the hazardous zone classification of the organization as well, calculated based on  the standard.

(EN 60079-10-2 – Explosive Atmospheres- Part 10-2: Classification of areas – Explosive dust atmospheres)

Equipment used in explosive dust atmospheres are ex-proof and in special designs. Selection of these equipment is made based on the hazardous zone classification of the organization. Therefore, organizations where explosive atmospheres may arise, must have a hazardous zone mapping.

Design-project inspections and hazardous zone classifications are covered in EN 60079-10-2 standard in detail. A design-project report based on EN 60079-10-2 is drawn up for the organizations, and this report includes the hazardous zone classification of the organization as well.

EN 600979-10-1 and EN 60079-10-2 standards form the basis for this zone mapping according to EU regulations. Topics covered by the standard are as follows:

  • Procedure for classification of hazardous places
  • Escape/release of explosives – potential release sources
  • Definition and scope of hazardous places
  • Documentation for classification of hazardous places
  • Examples of hazardous place classification

(EN 60079-14 – Electrical appliances – Part 14: Electrical installations design, selection and erection)

Electrical appliances and installations used in areas with potentially explosive gas and dust atmospheres must have special designs. The most important requirements for these organizations are; the design of electrical appliances and installations to be used on sites whose hazardous zone classification has been made according to the related EU standards and regulations (EN 60079-10-1; EN 60079-10-2; ATEX 99/92/EC), and the selection and correct installation of these equipment.

The conformity examination based on EN 60079-14 standard includes a detailed assessment of the electrical appliances and installations used in explosive atmospheres. A conformity report based on EN 60079-14 is drawn up for the organizations, and this report shows that the electrical appliances and installations are selected and erected in conformity with the requirements of the standard.

EN 60079-14 standard lays out the basis for the correct design, selection and erection of the electrical systems used in potentially explosive atmospheres according to EU regulations.
