The main topic of this paper is to analyse the approach to fault – finding, tests and maintenance regarding on what shall and shall not be done in an installation in hazardous area from the point of view of the explosion – protection safety. For a fault it is usual to be investigated by following a logical routine. This is one possible ways of proceeding developed from good engineering practice and experience in general terms. The test equipment for use in hazardous area will be either certified or uncertified. The maintenance is regarding in this paper from the point of view of SR EN 60079 – 17 starting from general requirements.

“…On the market is a wide variety of equipment to perform testing, [3][4]. They may be intended for use in potentially explosive atmospheres or not.…”

“…In the explosion risk assessment for an installation that process flammable substances, which is the responsibility of the owner of this installation, the main objective is to identify the hazards or sources of ignition/explosion. The electrical or non-electrical equipment and components that make up the installation are one such potential ignition/explosion source [4][5][6][7][8]. Even if such equipment and components are certified to operate in a specific explosive atmosphere, the characteristics of the type(s) of explosion protection applied may be invalidated by improper activities of design, installation, commissioning, use or maintenance.…”

Technological installations processing flammable substances in the form of gases, vapours, mists, dusts, lint or fibres create special spaces in their vicinity called explosive atmospheres classified into zones. For these installations to operate safely, they must be designed, installed, operated, maintained and repaired by personnel qualified and authorised to carry out these activities. In the first part of the paper the risk of explosion that may occur in the performance of these activities by the personnel involved is presented. In the second part of the paper, the importance of personnel authorisation in the field of explosive atmospheres and the authorisation procedure at national level is presented. In the third part of the paper statistical analysis and trends in the authorisation process in Romania are presented.

SR EN 60079 is a series of standards for the use of equipment in explosive atmosphere that covers a wide range of considerations for them, as well as the definition of various classifications of hazardous areas. An important section of the series specifically covers the repair, overhaul and modification of equipment. This is different from the maintenance of equipment, unless the repair and overhaul cannot be separated from the maintenance. SR EN 60079-19 edition 2020 establishes the general principles of repair, revision, and modification, which are common to all explosion-proof equipment, with additional clauses to provide instructions relevant to certain types of protection. Assuming that repairs and revisions are carried out using good engineering practices and details of the certificate, then the final equipment is considered to comply with the original standard and the manufacturer's specifications. Where these specific data are not available, the equipment can be simply described as having been repaired in accordance with SR EN 60079-19 and the relevant standards for which the equipment was designed.
