2 A Systems-based approach to safety requires the application of: Scientific, technical and managerial skills of hazard identification, Hazard analysis, and elimination, control, or management of hazards Throughout the life-cycle of a system, program, project or an activity or a product ACSF Safety Symposium 2

3 ACSF Safety Symposium 3

4 It does not mean threat. An indication of impending danger or harm (dictionary.com) It does not mean a hazard. A description of a condition that can impair our mission or task accomplishment. Hazard does not contain a significance factor. (Transportation Safety Institute) It does not identify hazards. Data does this. ACSF Safety Symposium 4

5 A quantifiable measure of hazard or danger that incorporates the potential magnitude of loss the likelihood of occurrence ACSF Safety Symposium 5

6 You've carefully thought out all the angles. You've done it a thousand times It comes naturally to you You know what you're doing, it s what you've been trained to do your whole life ACSF Safety Symposium 6

7 The possibility of suffering harm or loss; danger.(dictionary.com) Guides subjective assessment for hazard analyses: Probability Severity Points to effective discussion of intervention strategies or Risk management ACSF Safety Symposium 7

8 The willingness to examine, recognize, report and discuss conditions that require a remedy is the foundation of flight safety. Mick Quinn, V.P. Safety, Emirates Airlines Risk contains a significance factor. Risk is managed in all we do: On and off duty Driving our cars, driving our golf balls, etc. ACSF Safety Symposium 8

9 All safety concerns and findings are evaluated for risk. There are various tools and methods available to assist in this process. Must developed a unique approach that incorporates two key elements: probability and severity of reoccurrence MIL-882d ACSF Safety Symposium 9

10 The Risk Assessment Matrix is used to translate these two elements of risk to an assessment scale From the assessment of risk springs management of risk and intervention strategies MIL-882d ACSF Safety Symposium 10

11 Standard Risk discussions bring all perspectives to a universal understanding Vital to the Corporate understanding of the hazards Allows the organization to rank the hazards Vital to prioritization of risk Intervention resources Allows for collaborative management of the hazard Produces the best intervention strategies ACSF Safety Symposium 11

12 ACSF Safety Symposium 12

13 Requires formal documentation of each hazard s Risk potential Goes beyond expressing safety as goals or accomplishments Precedes reaction to unplanned events Avoids ambiguous safety requirements Integrates multiple perspectives into a universal understanding ACSF Safety Symposium 13

14 ACSF Safety Symposium 14

15 Almost anything can be defined as a System From an integrated circuit to an entire airline ACSF Safety Symposium 15

16 Draw a box Remove the Hazard Mitigate the hazard ACSF Safety Symposium 16

17 System Safety Order of Precedence (SSOP) Identify hazards within a system. Mitigate, eliminate or accept the hazard! Using the SSOP: 1. Eliminate hazards through design selection 2. Incorporate safety devices 3. Provide warning devices 4. Develop procedures and training 5. Accept the Hazard ACSF Safety Symposium 17

18 System Safety Order of Precedence (SSOP) Four levels or orders of safety precedence (protection) The level of protection are not linear They are exponential Order of Magnitude ACSF Safety Symposium 18

19 Highest level: Design or Engineer the Hazard out of the system Second level: Provide Guards or Barriers against the Hazard (physical or digital) Third level: Provide the operator with Cautions or Warnings Fourth level: Provide Procedures and Training Additional level: Accept the Risk ACSF Safety Symposium 19

20 1. Design: Strength of the Vertical Stabilizer & Rudder System 2. Safety Devices: The Rudder Limiting Systems & Yaw Damper 3. Warning Devices:????? 4. Procedures & Training 5. Accept the Risk (Hazard) ACSF Safety Symposium 20

21 Because your senior leadership knows your Company can t afford an accident Because your insurance company knows your Company can t afford an accident Because your clientele knows your Company can t afford an accident You are your Company s Last Line of Defense Risk Management vs Accident Event ACSF Safety Symposium 21

22 If you think designing, implementing and supporting a fully functional Safety/Risk Management System is expensive. Try having an accident someday ACSF Safety Symposium 22

23 ACSF Safety Symposium 23
