plan to prevent sources of ignition being brought in.

Examples of controlling hazardous area risks and control measures include: Hazardous area classification should be carried out as an integral part of a site risk assessment and should be used to identify any places or working areas in which ignition sources are required and also to identify areas in which such controls are not needed.

Zone 1 and Zone 2 isolators (switch disconnectors) are ATEX certified to Ex d or Ex e for hazardous area installation – housed in heavy duty cast iron or cast aluminium enclosures with 16A-250A current ratings, 3-4 pole including fire resistant isolators for safety critical electrical circuits. In this context, Therefore, it is very important to make sure that you are using a suitable luminaire for your application by choosing your fitting based on its suitability for the Zone in which it will be located…. by an area classification study.
