MODULE DETAILS

Machinery Safety and Safe Lifting DMEMSS613

Nominal duration: 48 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 an overview of machinery safety issues, introducing the concepts of hazard identification and risk reduction, international safety control standards, SIL, PL and Safety Categories. It also covers practical examples such as guard door interlocking applications, two-hand controls, muting, area protection of robot installations, motion detection, safety PLCs and safe networking principles as applicable to larger automation applications.  The module concludes by covering the fundamental principles of safe lifting, an overview of legal requirements, load balancing, lifting tackle and lifting machines.

MODULE PURPOSE

The purpose of the module is for participants to enhance their knowledge and appreciation of safe work practices, particularly in relation to machinery safety and safe lifting.

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

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 will 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.
