For this assessment you will be required to complete 10 online quizzes, each assessing your understanding of the learning materials from a different week. Quizzes will cover the material from weeks 2 to 11.

It is important that quizzes are completed in a timely manner following each topic, so each quiz will be open for two weeks only. Each quiz will open on the Friday of the relevant week, and close on the Friday two weeks later. (For example, the first quiz will open on Friday of week 2 and close on Friday of week 4.)

Each quiz is worth 4% of your overall mark for this unit. Marks will be awarded for correct answers.

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. Your three selected case studies must 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

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

Your submission will be assessed against the following criteria:

Each case study analysis (10 marks)

Depth of analysis and level of accuracy for the following:

• Identify the selected case study (1 mark)
  
• Identify the form of energy immediately before control was lost (1 mark)
  
• Identify preconditions that make the event possible (1 mark)
  
• Describe the hazard control failure mechanism (2 marks)
  
• Describe the point in time that relates to the damage event (1 mark)
• Identify the space transfer mechanism (1 mark)
  
• Describe the energy transference that led to damage (1 mark)
• Identify the assets damaged (recipients) (1 mark)
  
• Identify the damage threshold of the recipients (1 mark)
  

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 form your own teams. 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 using the tool provided via Moodle.

Your submission will be assessed against the following criteria:

Introduction (2 marks)

• The intervention you will argue for
• The direction the submission will follow

Analyse of BLEVEs in the LPG industry (7 marks)

• Lessons learned
• Interventions (control measures) available

Discussion (8 Marks)

• Merits of various interventions
• Consideration of hierarchies of control, practicality and cost-benefit
• Your opinion based on reputable and credible evidence
• Depth of discussion

• Clear and to the point
• Suitable implementation (action plan) for the intervention(s) recommended

Conclusion (2 marks)

• Implications of your recommended intervention(s)
• Includes no new information
• Draws to a logical end

Argument is persuasive (2 marks)

• Makes logical connections between evidence, opinion and recommendations
• Written expression is concise and precise
• Format, grammar and spelling support readability

References (2 marks)

• Consistent with Harvard Style (located in the unit profile)
• Contains at least 10 reputable references, 4 of which are peer-reviewed journal articles
