So, How Do You Select An Appropriate Method? Use ISO Guides As A Starter Kit
Order & download all ISO documents online immediately from
Basic documents for a well-known, world-wide accepted risk management method: Risk management definitions ISO GUIDE 73:2009
Application to Safety & Health ISO GUIDE 51:1999

How Does Risk Management Really Work? Are My Residual Risks Tolerable?
1 Identified hazard...
3 ... Implement a solution
2 ... Risk Assessment
4 ... Check Residual Risks
Controlling Risks of Large Tunnels – Alfred Moergeli (www.moergeli.com), European Tunneling Seminar No. 8, 09/25/2012 13
How Do I Get A Risk Register …? Begin With A Risk Shortlist
Controlling Risks of Large Tunnels – Alfred Moergeli (www.moergeli.com), European Tunneling Seminar No. 8, 09/25/2012 14
1. Definition of your System’s Limits (“Context”)
How Does Risk Management Really Help You? Higher Productivity & Safety with Lower Costs
2. Register of all your relevant hazards 3. System Safety by a Safety System
4. Optimization of your processes 5. Higher productivity & safety, lower costs 6. Comprehensible communication of your Residual Risks 7. Transparent documentation 8. Win legal compliance, your liability remains limited 9. Rest well (again) at the end of the day!
Controlling Risks of Large Tunnels – Alfred Moergeli (www.moergeli.com), European Tunneling Seminar No. 8, 09/25/2012 15
Is Your Risk Mitigation Complete? Use a Safety System to Achieve System Safety
Use a Safety System (STOP) 1 Substitution System / Strategy 2 Technology 3 Organizational / Personal Measures (Administrative Controls) To end up with System Safety => US Military Standard 882 D, 02/10/2000, Appendix A, A 4.3.3, i. requires: You must not use behavior oriented measures only
if hazards can cause an irrecoverable outcome!

How Do I Keep Track Of All My Risks? Visualize Your Risks – Before And After Mitigation
Are your risks tolerable? Use a Risk Map (“Before” & “After”) as a graphic decision tool.
