Simultaneous/Sequential Timed Events Plotting Analysis (STEP)

- Analyzes events from time/sequence perspective used to reconstruct an accident - Identifies "actors" and actions

Fault Tree Analysis - description, 4 classes of causal events, cut set, issues

- DEDUCTIVE/TOP DOWN (general to specific) and QUANTITATIVE - Looks at SINGLE ADVERSE EVENT and identify combinations of conditions/component failures that lead to the event; calculates PROBABILITY for each event cause - 4 classes of causal events: Primary failure, secondary failure, primary fault, secondary fault - Cut set: factors which on their own would lead to the top event - Difficult to identify all events that lead to top event and assigning valid probabilities to event causes - EFFECT --> CAUSE

Management and Oversight Risk Tree (MORT)

- Derivative of Fault Tree Analysis used as program management and logic tool - Idealized version of system safety model, focuses on 3 main concerns: specific oversights and omissions (S), management oversights and omissions (M), and assumed risks (R) - R-branch: events and conditions that are known to management and that have been evaluated and accepted at the proper management level - S-branch: focuses on the events and conditions of the actual or potential occurrence, uses barriers for control - M-branch: supports a process in which specific findings from an accident investigation or safety programme evaluation are made more general.

What are some examples of reliability regimes for safety-critical systems (fail passive, fail operational, fail safe, fail soft)?

- Fail passive: Continues to operate in the event of a system failure - failure does not have effect on operation of overall system (e.g., an aircraft autopilot). - Fail operational: Continue to operate when their control systems (discrete failure) fail, can be unsafe. Nuclear weapons launch-on-loss-of-communications was rejected as a control system for the U.S. nuclear forces because it is fail-operational: a loss of communications would cause launch -Fail safe: Design feature that allows failed component to revert to safe mode - Fail soft: Continues to operate in limited capacity (spare tires)

Human Factors - Accidents are entirely due to human errors, categorized as overload (environmental, internal, situational), inappropriate worker response, inappropriate activities 3. Accident/Incident (Petersen's Theory) - Human Factors theory (overload) plus ergonomic traps (incompatible workstations), decision to err (may be unconscious or based on logic, system failures (policy, training, inspections, etc.) - establishes role of management - Prone to "Superman Syndrome" - leads people to believe they are immune to accidents 4. Epidemiological - Focuses on industrial hygiene, looks at environmental factors and disease/accidents - Worker characteristics/predisposition and environmental factors 5. Systems Theory - Relationship between man (most flexible/valuable), machine systems (hardware), surroundings - Collect information, weigh risks, make decisions 6. Energy Release - William Haddon, based on vehicular safety - Accidents in terms of energy and transference - accidents are caused by out-of-control energy 7. Behavior Theory - aka behavior based safety - Includes identification of internal factors, motivation, focus on positive consequences, planned interventions, etc. 8. Modern causation model - 7 avenues to demonstrate causes of accidents - Safety management error, safety program defect, command error, system defect, OPERATING ERROR (unsafe acts/conditions), MISHAP (accident), RESULTS (injury)

Self-actualization (ongoing): Can accept human nature addressing shortcomings and failures; focus on solving problems for the greater good - problems considered "task that they must do" Herzberg - Hygiene factors (affect level of dissatisfaction): Physical working conditions, interpersonal relationships, policies and rules, supervisor quality, salary - cyclical in nature, new becomes the norm. Hygiene is used in a sense that they are "maintenance" factors that are necessary to avoid dissatisfaction. Should only be considered as ways of minimizing job dissatisfaction. - Motivation factors (affects job satisfaction): Achievement, advancement, recognition, responsibility, work itself, personal growth Vroom: - People can be motivated to perform when there are clear links between behavior and reward - individuals are going to select their behaviors based on the outcomes that they expect as a result of those behaviors McGregor: Theory X (employees don't want to work and are only motivated by money and Theory Y (employees like to work and seek out responsibility when needs are met) Grose: Performance, cost, schedule Grimaldi and Simonds: 3 steps - organizing, administrating, managing Bittel and Ramsey: Primary management functions, major business activities (finance, production, sales), environmental resources and constraints
