Objective
  • At the end of this module, participants will be
    able to explain the strengths and weaknesses of
    long-established approaches to manage safety and
    describe new perspectives and methods of managing
    safety by the State

4
Contents
  • A concept of accident causation
  • System performance in the real world
  • Safety management strategies Levels of
    intervention and tools
  • Hazards and safety risks
  • Safety risk assessment
  • Questions and answers
  • Points to remember

5
Concept of safety
  • Consider (the weaknesses in the notion of
    perfection)
  • The elimination of accidents (and serious
    incidents) is unachievable
  • Failures will occur, in spite of the most
    accomplished prevention efforts
  • No human activity or human-made system can be
    guaranteed to be absolutely free from hazard and
    operational errors
  • Controlled safety risk and controlled error are
    acceptable in an inherently safe system

6
Concept of safety (Doc 9859)
  • Safety is the state in which the possibility 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

A concept of accident causation

A concept of accident causation
10
A concept of accident causation
Actions or inactions by people (pilots,
controllers, maintenance engineers, aerodrome
staff, etc.) that have an immediate adverse
effect.

Three key definitions
  • Hazard Condition or object with the potential
    of causing injuries to personnel, damage to
    equipment or structures, loss of material, or
    reduction of ability to perform a prescribed
    function
  • Consequence Potential outcome(s) of the hazard
  • Safety Risk The assessment, expressed in terms
    of predicted probability and severity, of the
    consequence(s) of a hazard taking as reference
    the worst foreseeable situation

18
Three key definitions
  • Example
  • Unclear aerodrome signage is a hazard
  • A runway incursion is one of the consequences of
    the hazard
  • The assessment (quantification) of the
    consequences of the potential runway incursion
    expressed in terms of probability and severity is
    the safety risk

19
Understanding hazards
  • There is a natural tendency to describe hazards
    as their consequence(s)
  • Unclear aerodrome signage vs. runway
    incursion
  • Stating a hazard as consequence(s)
  • disguises the nature of the hazard
  • interferes with identifying other important
    consequences
  • Well-named hazards
  • allow to infer the sources or mechanisms of the
    hazard
  • allow to evaluate the loss outcome(s)

20
Types of Hazards
  • Natural
  • Technical
  • Economic

21
Examples of natural hazards
  • Severe weather or climatic events
  • E.g. hurricanes, major winter storms, drought,
    tornadoes, thunderstorms lightning, and wind
    shear
  • Adverse weather conditions
  • E.g. Icing, freezing precipitation, heavy rain,
    snow, winds, and restrictions to visibility

22
Examples of natural hazards
  • Geophysical events
  • E.g. earthquakes, volcanic eruptions, tsunamis,
    floods and landslides
  • Geographical conditions
  • E.g. adverse terrain or large bodies of water
  • Environmental events
  • E.g. wildfires, wildlife activity, and insect or
    pest infestation
  • Public health events
  • E.g. epidemics of influenza or other diseases

23
Examples of technical hazards
  • Deficiencies regarding
  • E.g. aircraft and its components, systems,
    subsystems and related equipment
  • E.g. an organizations facilities, tools, and
    related equipment
  • E.g. facilities, systems, sub-systems and
    related equipment that are external to the
    organization

24
Examples of economic hazards
  • Major trends related to
  • Growth
  • Recession
  • Cost of material or equipment
  • Etc.

25
Hazard analysis
26
Safety risk management
  • What is it?
  • The analysis and elimination, and/or mitigation
    to an acceptable level of the safety risks of the
    consequences of identified hazards
  • What is the objective?
  • A balanced allocation of resources to address all
    safety risks and viable safety risks control and
    mitigation
  • Why is it important?
  • It is a data-driven approach to safety resources
    allocation, thus defensible and easier to explain

27
Definitions
  • Probability
  • The likelihood that an unsafe event or condition
    might occur
  • Severity
  • The possible effects of an unsafe event or
    condition, taking as reference the worst
    foreseeable situation

Warm-up exercise N 02/01
  • Scenario
  • Fuel spill on the apron area surface of
    approximately 25 m (75 ft) length and 5 m (15 ft)
    width, produced by an A310 ready to pushback and
    taxi for departure

34
Warm-up exercise N 02/02
  • Scenario
  • It was observed that airline baggage handling
    personnel generates FO(D) on the aerodrome apron
    area
