HAZARDOUS AREAS
Directive and UKEX regulations by means of the acceptance of such amendments being “state of the art” for explosion protection. Finally, you may come across CSA, UL or FM certification. This is a broad system to ensure the safety of products used in North America, including Canada, whereby an OHSA or SCC-accredited Nationally Recognized Test Lab (NRTL) can certify that a product complies with specific North American safety standards.
There are several standards which apply to hazardous areas under the North American system; for example, FM 3615, UL 1203, and CSA C22.2 No. 30 are the standards for Explosion-Proof Equipment, while UL 674 and CSA C22.2 No. 145 cover “Electric Motors and Generators for Use in Hazardous (Classified) Locations”. Some North American explosion protection standards are harmonised with the IEC, ATEX and UKEX systems, and others are not. In addition, the North American system follows a different environment classification system.

While not a mandated safety standard, CompEx, (Competency in Ex atmospheres) is an exam-based competency certification scheme set up in the aftermath of the Piper Alpha disaster. Developed initially for operatives in the oil and gas sector, the scheme now operates globally, covering all personnel operating in potentially explosive atmospheres. CompEx currently offers 13 qualifications spanning a range of roles and environments.
