  2. Why is design so important to safety?

  3. What is safety in design? Safety in design is aimed at preventing injuries and disease by considering hazards as early as possible in the planning and design process.

  4. Design improvements over time

  5. How big is your window of opportunity? Concept selected Concept evaluation Final investment decision (FID) Conceptual design Front-end engineering design (FEED) Field activities Detailed design Construction Cost to change Field construct and install Production or operation Source: NOPSEMA

  6. See code of practice on safe design Safety in design life cycle

  7. What responsibilities do you have? Mines Safety and Inspection Act 1994, section 14 (1) A person who designs, manufactures, imports or supplies any plant for use at a mine must, so far as is practicable– (a) ensure that the design and construction of the plant is such that persons who properly install, maintain or use the plant are not, in doing so, exposed to hazards

  8. Reasonably practicable Quantum of risk severity and likelihood of event Sacrifice in time, money and trouble

  9. What are the consequences of poor design? Risk of injury or loss of life Environmental or equipment damage Loss of income Low productivity Higher operating costs Higher maintenance costs Reduced asset life Higher employment and workers’ compensation expenses

  10. Hierarchy of control – start at the top Increasing effectiveness What works? 10

  11. What is wrong with this? Access way next to conveyor take-up pulley

  12. What is wrong with this? Lifting lug welded to outside of conical bottom on powder-handling bin

  13. Standard drawings – lifting lug example

  14. What is wrong with this? Bag filling station – flat belt conveyor with roller bed lead-off conveyor

  15. What’s wrong with this? “Homemade” truck tyre cage modified with additional steel plating Source: http://www.alberthaviation.com/TireCageVideos.htm Tyre inflation cage

  16. What is wrong with this?

  17. Flaws in the design

  18. Top rail

  19. Top drive gear Bottom rail

  20. Consider not the cost of fixing a problem in the design stage, but the cost of not fixing a problem in the design stage!
