What is Compliance Check?

​

It refers to the inspection carried out in accordance with the TS EN 60079 and TS EN ISO 80079 standard series regarding the continuation of the features of the equipment used in a potentially explosive environment within the scope of the conformity certificate.

​

What is its place in legislation?
​
The maintenance of the existing or newly purchased equipment in the enterprises is carried out by the maintenance personnel in the workplaces or by subcontractor company personnel.

​

However, if the maintenance of the equipment in question is not carried out by personnel trained and certified in the maintenance of this equipment, the Ex feature of the equipment will be impaired and even its certificate will be invalid.

​

Installation, maintenance, major maintenance, modifications and revisions of Ex equipment must be carried out in accordance with the following standards published on the structure, inspection, repair and maintenance of electrical devices and electrical installations located in explosive gas environments:

​

The standards in question detail the details and requirements of installation, maintenance, major maintenance, modifications and revisions and have been published by TSE and made available as a TS EN standard.

​

REGULATION ON THE PROTECTION OF EMPLOYEES FROM THE HAZARDS OF EXPLOSIVE ENVIRONMENTS dated 30 April 2013 and numbered 28633 by the Ministry of Labor and Social Security states in ANNEX-2 Article 2.4. "If it is stated in the Explosion Protection Document that facilities, equipment, protective systems and related devices can be used safely in explosive environments, these can be put into service.

According to the Regulation on Equipment and Protective Systems Used in Possibly Explosive Environments (2014/34/EU), published in the 4th edition of the Official Gazette dated 30/12/2006 and numbered 26392, this rule is not considered as equipment or protective system, but they pose an ignition hazard in places where they are placed in the facility. It is also valid for the work equipment and fasteners that form it. "Necessary precautions are taken to avoid any confusion in the connection elements."

​

Again, in Annex-2 article 2.5 of the same regulation, "In order to minimize the risk of explosion and to control the explosion in the event of a possible explosion and to minimize its spread to the workplace and work equipment; design, construction and installation of workplaces, work equipment and all devices related to them." All necessary precautions are taken in its placement, maintenance, repair and operation, and whether the facility, equipment or protective systems continue to comply with the Regulation on Equipment and Protective Systems Used in Potentially Explosive Environments (2014/34/EU), and the status of their connections and installations. "Appropriate measures are taken to minimize the risk of employees being affected by the physical effects of explosions in workplaces." It is said.

​

In Annex-2 article 2.8 of the Regulation, it is obligatory for qualified persons to make this evaluation. According to the regulation; In workplaces with sections where explosive atmospheres may occur; Before starting the activity, it will be proven that the entire workplace is safe from explosion. All conditions are met to ensure explosion protection. Proving that explosion safety is ensured is done by competent people who are trained and/or experienced in explosion protection.

​

Regulation on Equipment and Protective Systems Used in Potentially Explosive Environments (2014/34/EU):

​

The Regulation on Equipment and Protective Systems Used in Potentially Explosive Environments (94/9/EC), published in the Official Gazette dated 30/12/2006 and numbered 26392, has been repealed.

• Have an understanding and working knowledge of relevant standards in the field of explosion protection,

• Basic knowledge of quality assurance, including calibration instrument and traceability principles in measurement

• to be.

​

Such persons must limit their involvement in major maintenance, repair and commissioning within their assigned competence area and must not undertake any activity on their own regarding the modification of explosion-protected equipment without expert advice.

​

In B.2.2, a regulation regarding maintenance personnel has been introduced. Maintenance personnel must have the following skills as necessary to perform their duties:

​​

• To have knowledge about the general principles of protection types and marking,

• To have knowledge about device design issues that affect protection,

• To have knowledge about inspection and testing in accordance with the relevant sections in this standard,

• Be skilled at introducing manufacturer-approved replacement parts and components.

• Be familiar with the special techniques to be used in the repair operations specified in this standard.

​

The competencies should apply to each of the explosion protection techniques with which individuals are concerned. For example, it is possible that a person is only competent in the field of repair and overhaul of Ex “d” motors and is not fully qualified in the field of Ex “d” switchgear or the repair of Ex “e” motors. In such cases, repair service management must indicate this in its documentation system.

​

In B.3.3, it is stated that the maintenance personnel must be able to demonstrate their competence and enable the acquisition of the rules regarding the knowledge and experience specified in Article B.2.2 regarding protection types and/or relevant device types.
