UEENEEM026A - Install explosion-protected equipment and wiring systems - pressurisation

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills and knowledge:

• explosion-protection equipment - ex certification schemes;
• flameproof (ex ‘d’) explosion-protection technique;
• increased safety (ex ‘e’) explosion-protection technique;
• non-sparking (ex ‘n’) explosion-protection technique;
• intrinsic safety (ex ‘i’) explosion-protection technique;
• pressurization (ex ‘p’) explosion-protection technique;
• enclosures for dusts (ex ‘td’) - explosion-protection technique;
• common characteristics of explosion-protection techniques;
• preparation to install and maintain explosion-protected equipment in hazardous areas;
• the relationship between explosion-protected equipment, their certification documents and required locations given in specifications and layout drawings and/or written instructions;
• installation standards and requirements applicable to hazardous;
• maintenance procedures in hazardous areas that will ensure the integrity of the explosion-protection technique;
• cable termination types suitable for use in hazardous areas, and;
• terminating cables suitable for use in hazardous areas.
