5 1. Concepts

6 1. Concepts Examples of Hazards and Their Effects Workplace Hazard Example of Hazard Example of Harm Caused Thing Knife Cut Substance Benzene Leukemia Material Asbestos Mesothelioma Source of Energy Electricity Shock, electrocution Condition Wet floor Slips, falls

7 1. Concepts Undesirable Event Event Loss Loss of of control of of the the situation UE= UE= all all event event phase phase which which can can lead lead to to an an accident accident without without efficient efficient barriers barriers Controlled area UE Recovery phase Safety principles: Manage to stay in safety controlled area Safety Safety model model :: An An accident is is assimilated as as a loss loss of of control of of the the situation MITIGATION Accident If an UE occurs, react to hold it back and to return into controlled area Mitigation to reduce the consequences of an accident Source: Qualit Audit 7

10 2. Hazard identification Hazard identification, risk assessment and mitigation process: 1. What am I the most afraid of in my activity? 2. How this event could happen? 3. What can be the consequences (for the company, for the others, on the environment )? 4. How can I reduce the probability of occurrence of this event (prevention)? 5. How can I reduce the consequences of this event (mitigation)? 6. What protective measures must be adopted and how can I put them in place to prevent this event?

15 2. Hazard identification What can lead to an engine failure? Engine system failure Fuel system failure Fuel pollution or inadequate fuel Loss of engine power No more fuel available!!! Wrong management of fuel system Wrong management of engine system

16 2. Hazard identification Foreign Object Damage Failure of a component (design) Lack of maintenance check Errors, violations during maintenance task No anti-pollution test before refuelling No formal refuelling procedures Errors, violations during refuelling No cross check of fuel quantity delivered after refuelling Wrong calculation of Minimum Fuel Quantity before flight Unplanned diversion in flight Lack of knowledge Improper action of the crew Engine system failure Failure of fuel system Fuel pollution or inadequate fuel No more fuel available!!! Improper use of fuel system Improper use of engine system Loss of engine power

23 3. Stay in safety controlled area FOD policy Foreign Object Damage Failure of a component (design) Apply OEM directives HUMS Safety barriers Lack of maintenance check Safety and Quality policy visibly endorsed by CEO Adequate supervision Engine system failure Updated and cleared work documentation Technicians trained and rated Adequate tools, workshop, environment No misson/time pressure («hurry up syndrom») «just culture» Failure of fuel system Errors, violations during maintenance task

24 3. Recovery phase Crew fights to keep the control of flight Crew is trained and applies the appropriate procedure Safety barriers Engine system failure Crew is trained and applies the appropriate procedure In flight diversion to emergency airfield Failure of fuel system Loss of engine power Loss of control Calculation of new flight endurance Crew is trained and applies the appropriate procedure Safety barriers

29 3. Risk management Several solutions are possible Adopting new procedures is costly Conduct a cost/benefit analysis (business case) Could be very detailed (exact costs, benefits) Could use relative values (low, medium, high)

31 3. Risk management Key role of risk continuous monitoring: Register your hazards and risks analyzis in a Database Reviews them periodically (set alarms) and when changes occur in your activity Use adequate risk management form (paper or electronic)

35 4. The importance of event report SAFETY MANAGEMENT SYSTEM SAFETY CULTURE (People oriented) RISK MANAGEMENT (System oriented) Human Factors Safety Com «Just culture» Occurrence reports (and feedback!) Risk analysis Accident prevention program Hazard identification Incident/accident investigation Source : QualitAudit/Air France consulting 35

36 4. The importance of event report Just culture is a culture in which front line operators or others are not punished for actions, omissions or decisions taken by them that are commensurate with their experience and training, but where gross negligence, willful violations and destructive acts are not tolerated. (Regulation (EC) 691/2010 )

37 4. The importance of event report The vicious circle of taboo "Good professionals don't make errors" Errors become faults I hide my errors It's easier for errors to have serious consequences Errors remain invisible to all The system cannot put in place protective barriers

38 4. The importance of event report The "virtuous" circle of feedback "Man is intelligent, he makes mistakes" Now over to you! I talk to my colleagues It's much less likely that my mistake will have serious consequences I decide to give feedback The organization puts in place protective measures The organization processes my report

39 4. The importance of event report The reality? Yesterday, I made a real blunder... Does our method interest other teams? I talk to my team It is less likely that this mistake will have consequences I can see that this is not the first time It puts in place protective measures to prevent it The team reflects on the problem

40 4. The importance of event report Encourage people to report: The operational staff are the ones who know the real situation Implementation of a non punitive policy Obstacles to this reporting: It is difficult to "confess" to a mistake Fear of being punished No corrective actions following the declaration of an event

41 4. Day to day risk management New hazard 1 Risk analysis Scenario of accident 2 When an incident or accident occurs, analyze of dysfunctions Hazard identification Database Event reports Lessons learned 4 Analyzis of root causes and unexpected outcomes 3 Analyzis of barriers efficiency 41
