General Information

Overview

This unit will help you make the connection between science and safety so that you will think scientifically to promote evidence-based safety practice. You will be introduced to the science that explains how hazards behave, the concept of energy conversion and how hazards cause harm. Management of health and safety risk is discussed from an evidence-informed perspective. Case studies will be used to assist you in developing an appreciation of the linkages between the causation of harm and fundamental theories of physics, chemistry, physiology and social sciences.

Assessment Grading

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%). Consult the University’s Grades and Results Policy for more details of interim results and final grades.

Previous Student Feedback

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Feedback from Student evaluations and staff observations

Feedback

Quizzes enabled continuous assessment throughout the term and provided students with an opportunity to immediately and regularly check in with their understanding of the material.

Recommendation

Continue to develop robust and diverse question banks to expand and improve upon the quizzes for future offerings of this unit.

Feedback from Staff observations

Feedback

Group work remains a challenge for students however the use of the Self and Peer Assessment tool allowed students the opportunity to highlight issues and successes in a constructive manner.

Recommendation

Promote the use of the Self and Peer Assessment tool for future group work in this unit and continue to encourage students to engage with their groups earlier in the term.

Assessment Tasks

1 Case Study

Assessment Title
Case Study Analysis

Task Description

The purpose of this assignment is to demonstrate that you can apply scientific principles to explain the process that resulted in damage or harm. You will be presented a list of case studies that involve various forms of energy.

You are required to select and analyse three case studies from the list provided on the Moodle Assessment page for this assessment. Your three selected case studies must each feature a different energy form.

Using the energy-damage model, each analysis must:

  • Identify the selected case study
  • Identify the form of energy immediately before control was lost
  • Identify preconditions that make the event possible
  • Describe the hazard control failure mechanism
  • Describe the point in time that relates to the damage event
  • Identify the space transfer mechanism
  • Describe the energy transference that led to damage
  • Identify the assets damaged (recipients)
  • Identify the damage threshold of the recipients
Students are more likely to be successful with submissions of 300-500 words per case study.

Referencing is not required for this assessment, but if you choose to utilise additional resources they should be referenced in accordance with Harvard Style.

2 Written Assessment

Assessment Title
Group Report

Task Description

The purpose of this assignment is to demonstrate application of evidence-informed thinking in regards to the management of a safety science problem.

This is a team assignment (up to 3 members). You can request your own teams, but must do so by email to the unit coordinator during or before week 3. If you are not in a team by Monday of week 4, you will be assigned to a team.

Case Study

Whites Petroleum Company has recently acquired a Liquid Petroleum Gas (LPG) storage and transfer facility that was founded in 1965. Due to past events, the managers of Whites Petroleum are aware that there is potential for Boiling Liquid Expanding Vapour Explosions (BLEVEs) in this industry. As a safety consultant, you have been asked to explain why and how BLEVEs may occur and to recommend intervention strategies that are practical, cost-effective, and specific to the LPG industry. The interventions you recommend need to be based on scientific principles.

Present your recommendations in the form of a summary report to the company. In your response, you should include:

1. A review of the literature relating to BLEVEs, including a summary of:

  • The conditions under which BLEVEs can occur
  • The chemical and physical properties of LPG
  • The potential for secondary fires and explosions following a BLEVE
  • Available risk control measures
  • Evidence from research in the field

2. A discussion of the merits of various interventions

3. Your considered opinion concerning the most appropriate intervention(s), based on the evidence you have reviewed

4. Your recommendations for implementing your chosen intervention strategy/strategies

Submissions of 1500-2000 words are more likely to be successful.

Each team member must also submit a Self and Peer Assessment. Access to this tool will be provided through Moodle or via email (to your CQU Student email address) towards the end of the term.


Assessment Due Date

Week 12 Monday (1 Jun 2020) 9:00 am AEST


Return Date to Students

Academic Integrity Statement

As a CQUniversity student you are expected to act honestly in all aspects of your academic work.

Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.

When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.

Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.

As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.

What is a breach of academic integrity?

A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.

Why is academic integrity important?

A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.

What can you do to act with integrity?

Where can I get assistance?

For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
