ATEX Lighting & Inspections: The Gold Standard for Safety

Thursday 11 February

How ATEX Inspections can help you

By providing ATEX certification you are saying that your equipment meets or exceeds the required ATEX standards required, with overall protection and peace of mind. 

Our engineers are highly trained and can provide a full hazardous area ATEX inspection, testing, installation, and maintenance service to clients nationwide throughout the United Kingdom.

ATEX Testing Frequency

To maintain the required workplace protection, all ATEX installations must be inspected on a regular basis. No more than 18 months after the original install, a minimum Visual grade of inspection must be carriedout, with any corrective work arising to be completed. After a further 18 months, a Close grade of inspection is required for complete maintenance. 

A new Detailed grade of inspection is required no more than 4 ½ years after the initial installation or previous Detailed inspection of the equipment.

Zone Classifications

Hazardous places are classified in terms of zones. These zones are based on how often and for how long the explosive atmosphere occurs. 

The following table explains the zoning schemes that apply:

Gases, Vapours & Mists

Combustible Dust

Likelihood of Occurrence

Zone 0

Zone 20

It is present continuously or for long periods or frequently.

Zone 1

Zone 21

It is likely to occur occasionally during normal operation.

Zone 2

Zone 22

It is not likely to occur in normal operation but if it does occur, it will be present for a short period of time only.
