Study Notes
- Intrinsic hazards are caused by material or design factors of system elements
- Functional hazards result from incorrect or unexpected system functions
- Socio-technical hazards arise from interactions between system, operators, and environment
- Car on icy road and inexperienced driver: accident hazard, mitigated by traction control, trained drivers, or not driving in icy conditions
- Failure to specify Maneuvering Characteristics Augmentation System (MCAS) as safety critical led to loss of two 737 Max aircraft
- Bull-bars reduce risk of injury in vehicle to vehicle or vehicle to large animal collisions but increase risks to pedestrians in vehicle to pedestrian collisions
- Asbestos or flammable substances present inherent hazards
- Failure to properly remove old wiring led to Clapham junction rail accident
- Misaligned mental models between operators, maintainers, and designers: false alarms led to overriding without investigation, resulting in Smiler accident
- Piper-Alpha oil platform accident caused by failure to properly manage design changes, poor maintenance management, and poor contingency planning
