  1. About Risk Assessment Sophia CHENG 3 Nov 2009

  2. Discussion on Risk Assessment

  3. Risk Assessment • An analysis of a practical activity to identify hazards and to take precautions to minimise the risk • Procedures: • Identifying hazards (Materials / Procedures / Equipment) • Assessing how likely the hazard will actually cause harm • Deciding what control measures to reduce risk to acceptable level • Finding how to dispose of hazardous residues

  4. Discussion on Risk Assessment – Sample 1 Investigation: Self-heating pack Risk Assessment

  5. Opinion on Sample 1 from Teacher A

  6. Response to Risk Assessment – Sample 1 Investigation: Self-heating pack Risk Assessment

  7. Safety information about chemicals • Material Safety Data Sheet (MSDS); CityU • http://cd1.edb.hkedcity.net/cd/science/laboratory/safety/msds_ss_2000.pdf • International Chemical Safety Cards; ILO • http://www.ilo.org/public/english/protection/safework/cis/products/icsc/dtasht/index.htm

  8. Hierarchy of Controls

  9. Another Example of Risk Assessment Form (1) Risk assessment form Title of the experiment / task Hazard identification – Equipment used & experimental design (Consider what hazards are posed by, both the equipment and the experimental procedures. What harm can happen to people or equipment?) Hazard identification – Materials Control adopted for risk minimization

  10. Another Example of Risk Assessment Form (2) Hazard identification – Materials

  11. Another Example of Risk Assessment Form (3) Control adopted for risk minimization

  12. Another Example of Risk Assessment Form (4) Further risk control measures (List any control measures implemented, which are not listed above.) (Review the current controls using the Hierarchy of Controls: )

  13. Another Example of Risk Assessment Form (5) Source(s) of information Disposal of residues

  14. Example of Risk Assessment - Volhard Method (1)

  15. Example of Risk Assessment - Volhard Method (2)

  16. Example of Risk Assessment - Volhard Method (3)

  17. Example of Risk Assessment - Volhard Method (4)
