Ex Inspection Consultation

1/9

The End users or the owner of a plant are responsible to periodically inspect their electrical installations. When electrical installations are installed in Hazardous environments.


According to International standards, we have 2 types of Ex inspections:
 

1. Initial Inspections

All new Ex installations must be subjected to an initial detailed inspection in accordance with IEC60079-17.
This is to determine whether all equipment has been correctly chosen according to zoning. In addition, to ensure such as Ex markings, category, Temperature class, Gas group, cable gland, and cable selection, calculations of intrinsically safe circuits, safety devices, seals, etc.

Make a list of all potential ignition sources( Ex register), measurements such as earth resistance, impedance, and insulation resistance measurements are also included at the detailed ATEX inspection.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


 

2. Periodic Inspections
 

At some point, periodic Ex inspections must be scheduled and carried out, in order to be able to check whether the Ex equipment is sufficiently maintained and that no defects occur that endanger the explosion safety. 

Periodic inspections need to be carried out as part of the overall maintenance and apply to existing installations. The periodic inspection will identify any change and/or deterioration and should not exceed 3 years.

Dependant on interval and requirements an visual or close inspection report would be issued.

 

Ex Inspection Grades:

We have are 3 grades of ATEX & IECEx Inspections:
 

1. Visual Inspections

Visual hazardous area inspections identify without the use of access equipment or tools, those defects, such as missing bolts, visible damage, etc. which will be apparent to the eye.
 

2. Close Inspections

Close hazardous area inspections encompass those aspects covered by visual inspection, and in addition, identifies those defects, such as loose bolts, which will be apparent only by the use of access equipment, and tools. Close inspections do not require the enclosure to be opened, or the equipment to be isolated.
 

3. Detailed Inspections

Detailed hazardous area inspections will encompass those aspects covered by close inspection and, in addition, identify those defects, such as loose connections, which will only be apparent by opening the enclosure. These inspections require the enclosure to be opened, equipment to be isolated and opening of cable glands, as per the IEC 60079-17 Inspection & Maintenance Standards
