DEISIS619 : Safety Instrumentation and Emergency Shutdown Systems

Nominal duration: 24 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 safety life cycle, risk reduction, safety targets, and planning for effective system integration, documentation, diagnostics and testing.


The purpose of the module is for participants to develop introductory working knowledge of safety instrumentation and shutdown systems and be able to determine and oversee procedures for plant safety.

MODIFICATION HISTORY Original module approved in 2010 (52368WA); April 2014 (52684WA).  This version is Version 3.0


Modules that must be delivered and assessed before this module:

  • Electrical Equipment in Hazardous Areas DEIHAZ611

Modules that must be delivered concurrently with this module:

  • N/A




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.


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.


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

  1. Analyse safety life cycle, risk reduction and safety targets
  2. Plan effective system integration, documentation, diagnostics and testing

Learning Outcomes

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


Assessment criteria provide the criteria by which achievement of the learning outcomes will be judged.
