Periodic Inspection of Electrical Installations in Explosive Atmospheres."},"content":{"rendered":"<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>Short answer:<\/strong> IEC 60079-17 specifies that electrical installations and equipment located in explosive atmospheres (gas, vapor or dust) must be inspected after initial installation. <strong>remaining safe throughout its operational life<\/strong> It is a standard for periodic inspection and maintenance applied to ensure compliance. Inspections <strong>visual, close-up and detailed<\/strong> It divides them into three categories and defines the frequency of performance according to the risk level.<\/p><\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Even a perfectly designed and correctly installed Ex-proof system will deteriorate over time. Corrosion, vibration, overheating, humidity, and the most dangerous of all... <strong>unauthorized alterations<\/strong>, It silently destroys the explosion protection capability of the equipment. The facility is just as safe in the fifth year as it was on the first day. <strong>proving<\/strong> The only mechanism is periodic inspection. IEC 60079-17 is the international standard that specifies how, by whom, and at what depth this inspection should be carried out.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why is it critical? Legal and operational necessity.<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In T\u00fcrkiye, Ex-proof inspection is not an option for businesses with explosive environments., <strong>legal obligation<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Occupational Health and Safety Law No. 6331<\/strong> And <strong>Regulation on Protection Against the Hazards of Explosive Atmospheres<\/strong> businesses within the scope <strong>Explosion Protection Document (EPD)<\/strong> must prepare.<\/li><li>For the PKD to remain valid, the equipment must comply with IEC 60079-17. <strong>regular check-ups<\/strong> It depends.<\/li><li>An accident occurring in an uninspected Ex zone would result in both... <strong>serious criminal\/legal responsibility<\/strong> as well as <strong>insurance invalidity<\/strong> She gives birth.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Which sectors and businesses are included?<\/h2>\n\n\n<p class=\"wp-block-paragraph\">All production and storage areas where flammable gas, vapor, mist or flammable dust is likely to be present fall under the scope of IEC 60079-17. The main establishments with explosive atmosphere (Ex) zones are:<\/p>\n\n\n<ul class=\"wp-block-list\"><li><strong>Petrochemicals and refineries:<\/strong> Process units, pumping stations, filling yards.<\/li><li><strong>Fuel and LPG\/CNG stations, tank farms:<\/strong> Loading\/unloading areas and storage tanks.<\/li><li><strong>Chemical, paint and solvent plants:<\/strong> Production and mixing areas where solvent vapor is generated.<\/li><li><strong>Food and feed industry:<\/strong> Silos and grinding lines where combustible dust such as flour, sugar, and starch is generated.<\/li><li><strong>Pharmaceutical and cosmetic manufacturing:<\/strong> Process areas outside of cleanrooms where alcohol and solvents are used.<\/li><li><strong>Natural gas and biogas plants, wastewater treatment:<\/strong> Indoor spaces where methane accumulates.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Three Inspection Levels According to IEC 60079-17<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The standard defines the inspection in three stages according to its depth:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Degree<\/th><th>Energy status<\/th><th>What can be done?<\/th><th>Typical usage<\/th><\/tr><\/thead><tbody><tr><td><strong>Visual<\/strong><\/td><td>It cannot be cut.<\/td><td>Without tools or ladders, visible defects (broken glass, loose bolts, missing gaskets) can be detected.<\/td><td>Frequent preliminary checks<\/td><\/tr><tr><td><strong>Close<\/strong><\/td><td>It cannot be cut.<\/td><td>Using a ladder or similar tool, but without opening the equipment, the presence of bolts, fittings, and sealing elements is verified up close.<\/td><td>Periodic inspection<\/td><\/tr><tr><td><strong>Detailed<\/strong><\/td><td><strong>It is cut<\/strong><\/td><td>The covers are opened; moisture, corrosion, and deactivated Ex protection systems in the internal piping are tested with instruments.<\/td><td>Initial examination + increased risk<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What should the inspection period be?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">IEC 60079-17 does not impose a fixed calendar; the period <strong>the risk level of the region, environmental conditions and the condition of the equipment<\/strong> It determines. In general practice, the first detailed inspection is carried out during commissioning, then... <strong>not exceeding 3 years<\/strong> Periodic inspections are repeated at intervals; under severe conditions (high corrosion, vibration, frequent intervention), this interval is shortened. The correct period is determined by a risk assessment of an accredited inspection organization.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who can perform the examination?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ex-proof inspections must be carried out by a &quot;competent person&quot;. For the report to have legal and international validity, the inspection must be completed. <strong>Accredited by TURKAK (TS EN ISO\/IEC 17020)<\/strong> It is essential that this be carried out by an inspection organization.

One says &quot;set it up right,&quot; the other says &quot;keep it safe.&quot;.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What happens if I don&#039;t get my regular checkups?<\/h3>\n\n\n<p class=\"wp-block-paragraph\">The PKD (Product Protection Law) loses its validity, non-conformities and administrative fines arise during occupational safety and health (OSH) audits, and employer liability and insurance invalidation come into question in the event of a possible accident.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is visual examination sufficient?<\/h3>\n\n\n<p class=\"wp-block-paragraph\">No. Visual inspection only detects superficial defects; internal corrosion, moisture, and deteriorating Ex protection can only be detected. <strong>detailed examination<\/strong> It is determined by...<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does the examination take and when will I receive the report?<\/h3>\n\n\n<p class=\"wp-block-paragraph\">The duration depends on the size of the area, the number of pieces of equipment, and the level of inspection. A typical site visit takes 1-3 days; the accredited inspection report is usually delivered within a few business days after the site visit. Expedited reporting can be planned in urgent cases.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Keep your explosion-proof plumbing system safe.<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Document the IEC 60079-17 compliance of your explosive atmosphere installation with T\u00dcRKAK accredited, internationally valid reports.
