3 3 Fear of harm ought to be proportional not merely to the gravity of the harm, but also to the probability of the event A. Arnoud, La Logique, or lart de penser, 1662

4 WOS2006| 4 Primary objectives Development of a methodology to support the definition of a risk reduction strategy –Optimising reduction of consequences, probabilities and costs Application of the methodology to 25 hazardous activities –That take place in activities or occupations –Allowing the construction of a risk profile for that occupation –And developing a risk reduction strategy The ultimate application takes place in the enterprises.

7 WOS2006| 7 Fault-tree Accident Basic causses Event-tree Damage Bow-tie Everything leading up to the accident Verything following the accident

8 WOS2006| 8 Prevent accidents Take away causes Make barriers

9 WOS2006| 9 Fault-tree Basic failure events Event-tree Outcomes rotha Effectiveness of a barriers Need number before and after

10 WOS2006| 10 Barriers are not perfect

11 WOS2006| 11 Level of measures population With reportable accidents population without reportable accidents

12 WOS2006| 12 METRIC The injury classes are –Death –Permanent injury –Recoverable injury Risk is expressed as the frequency of having each of the three possible consequences per year of work.

31 WOS2006| 31 Deaths 1 Permanent injuries 10 Recoverable injuries Ladder accidents Every year there are on average 3 deaths from falls from a ladder, 30 permanent injuries and 90 recoverable serious injuries

32 WOS2006| 32 Deaths 1 Permanent injuries 5 Recoverable injuries Scaffold accidents Every year there are around 70 falls from scaffold accidents

33 WOS2006| 33 Deaths 1 Permanent injuries 7 Recoverable injuries 9 2. Struck by moving vehicle Every year there are around 120 work accidents where a person is struck by a moving vehicle. 6% of cases analysed resulted in death In all the cases of death the victim was in an area normally designated safe In all cases management failed to provide adequate barriers at some point in the scenarios

34 WOS2006| 34 Deaths 1 Permanent injuries 5 Recoverable injuries 4 3. Falling/dropped/collapsing objects Every year there are on average 240 accidents

35 WOS2006| Machine accidents A first pass assessment suggests that every year there are around 500 machine accidents in Nederland involving contact with moving parts Deaths 1 Permanent injuries 40 Recoverable injuries 10 Humans are no match for machines
