MODULE DETAILS

DEIHAZ611 : Electrical Equipment in Hazardous Areas

Nominal duration: 36 hours total time commitment

This time commitment includes the structured activities, preparation reading, and attendance at each webinar, completing exercises, practical assessments and proctored assessments.

It is also expected that students spend additional time on readings, personal study, independent research and learning, practicing on remote labs and required software and working on any projects and assignments.

This module covers the fundamental principles of hazardous areas, explosion protection (Ex) principles, and recommended end-user principles for hazardous areas

MODULE PURPOSE

The purpose of the module is for participants to deepen their knowledge and awareness of hazardous areas and safety.

ASSESSMENT STRATEGY

 

METHODS OF ASSESSMENT

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, structured assessments, samples and questioning. This will include short answer questions on the knowledge content, the use of remote and virtual labs, and writing tasks to apply the learning to academic tasks.

CONDITIONS OF ASSESSMENT

Assessor Requirements:

Assessors must satisfy the assessor requirements in the standards for registered training organisation (RTOs) current at the time of assessment.

Assessors must also hold a tertiary qualification in engineering or related field.

The RTO must also ensure that trainers and assessors keep their industry knowledge up to date through ongoing professional development.

Assessment Conditions:

Questioning techniques should not require language, literacy and numeracy skills beyond those required in this module. The candidate must have access to all tools, equipment, materials and documentation required.

The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Assessments may be open book assessment and may be completed off campus. Invigilation software will be used for some assessments to ensure authenticity of work completed.

Model answers must be provided for all knowledge-based assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.

SUMMARY OF LEARNING OUTCOMES

On successful completion of this module students will be able to:

  1. Explain the fundamental characteristics of hazardous areas
  2. Outline the principles of the various types of Ex protection
  3. Outline end-user practices for hazardous areas

Learning Outcomes

Learning outcomes specify what students will be able to do as a result of the learning.
