This course has been developed in consultation with industry to ensure the core competence of existing and potential workers who operate in these environments.
The qualification consists of four units, which cover the minimum requirements for safe working practices in hazardous locations.
Candidates will learn about the safety considerations that should be applied to work areas that contain potentially explosive or flammable atmospheres and the factors that are used to classify their location.
The course includes instruction on how to read hazardous area certification, labelling and documentation, and also informs candidates about the main protection concepts, categories and levels that are applied to certified Ex electrical equipment.
Successful candidates will demonstrate the knowledge and skills to meet the requirements highlighted in the IEC 60079 series of standards and the relevant national standards and directives. This qualification focuses on the minimum specifications identified in IEC60079:0, IEC60079:10.1, IEC60079:14 and IEC60079:17.
Key learning objectives
Candidates that successfully complete the Ex01-Ex04 qualification will be able to:
- Identify the correct national regulations, directives and IEC standards which are applicable to hazardous locations.
- Identify the correct criteria and descriptors used to classify a hazardous location.
- Recognise the correct characteristics of common hazardous gases and vapours discussed during the course.
- Demonstrate an underpinning knowledge of how certified Ex electrical equipment including Ex ‘d’, ‘e’, ‘n’, ‘p’, ‘m’, ‘o’, ‘q’, ‘s’, Intrinsic Safety (IS) maintains its protection concept and how it is to be selected, installed, inspected and maintained.
- Identify the correct test value readings for IS and non-IS installations and equipment.
