Store og små ulykker Indikatorer for styring av sikkerhet
Storulykkesrisiko Arbeidsulykkesrisiko • Hovedkarakteristika: • Multi-lineær hendelseskjede • Kompleks årsakssammenheng • Potensielle katastrofale konsekvenser • Potensial for spredning/eskalering • Hovedkarakteristika : • Lineær hendelseskjede • Enklere årsakssammenheng • Vanligvis begrensede konsekvenser
The Reason Model: The Organisational Accident Organisational factors Task/Environmental Conditions Individual/ Team Actions Defence Barriers Management Decisions and Organisational processes Error producing conditions Violation producing conditions Errors Violations Accident or major Incident

Bakkehendelser • 27000 ulykker og hendelser på ramp hvert år • 243000 personskader hvert år – omlag 9 pr 1000 avganger “IATA attributes the problem to "minimal oversight" of ground service providers in the selection and licensing process, in systems implementation, training and development, and in auditing, reporting and compliance procedures”
Kostnader • Flight Safety Foundation: Dobbelt så høyere kostnader som antatt – nær 10 milliarder dollar hvert år “The reason, says the FSF’s Ground Accident Prevention (GAP) programme analyst, Dr Earl Weener, is that personal injury costs had been “right off the radar” for the airlines, but have now been estimated for the first time at $4.4 billion in addition to the $5 billion cost of aircraft damage repair, downtime and delay”
Styring av sikkerhet Safetyis the state in which the risk of harm to persons or property damage is reduced to, and maintained at or below, an acceptable level through a continuing process of hazard identification and risk management(ICAO, DOC 9859)

Leading indicators: Active monitoring: provides feedback on performance before an accident or incident Check that key actions or activities are undertaken as intended Lagging indicators: Reactive monitoring: reporting and investigation of specific incidents Show when a desired safety outcome has failed, or has not been achieved Leading indicators / lagging indicators Hentet fra Developing process safety indicators.

Bakkeskader og flight safety Monday 26/12 2005 Alaska Airlines Flight 536 was 20 minutes out of Seattle and heading for Burbank, Calif., Monday afternoon when a thunderous blast rocked the plane. An investigator with the National Transportation Safety Board (NTSB) said baggage handlers had bumped the plane's fuselage with loading equipment and caused "a crease" in the side of the aircraft
