Contractor Health & Safety Assessment Scheme.

CHAS started with two main aims:

  1. To improve health and safety standards across Great Britain.
  2. To reduce duplicated safety applications for both suppliers and buyers.

Assessing suppliers health and safety competence is usually a lengthy and time consuming process. Suppliers can sometimes meet one buyer’s Health and Safety standards but not another. Being CHAS approved reduces duplication as suppliers compliance is accepted by all CHAS buyers.

Based upon the IEC Standards, primarily 60079: 10; 14 & 17, CompEx is the global solution for Competency Validation and Certification for electrotechnical and mechanical craftspersons working in potentially hazardous or explosive atmospheres.

Potentially explosive atmospheres occur in onshore and offshore petrochemical plants and refining plants. They are also found in distilleries, paint spraying plants, flourmills, woodworking machine plants, the water industry and petrol & fuel forecourt environments. Failure to ensure safe working practices in these circumstances could result in the ignition of explosive gases or dust clouds leading to injury or even fatalities.

Competency is certificated only to individuals who:

  • Meet the necessary entry criteria for the CompEx modules
  • Pass the underpinning knowledge theory examinations
  • Pass the competency validation test in the form of a practical assessment
