What is the definition of a risk analysis?

A

A formal method to identify,
evaluate and manage hazards and risks
that is employed in many parts of life –

Q

What are the 4 steps that comprise a risk assesment?

A
  • Hazard identification (what is the agent of concern)
  • Hazard characterisation (what are the consequences of exposure to the hazard)
  • Exposure assesment (who or what may be affected by the hazard)
  • Risk characterisation (how likely is the adverse outcome to occur)

Q

What are the steps in a risk assesment?

A
  1. Frame the question
  2. identify potential risk factors
  3. Outline the risk release pathway
  4. Collect the information
  5. Assess the risk
  6. Evaluate intervention measures

Q

What are risk managers?

A

decision-makers, e.g politicians or owners of enterprises- they are not typically responsible for the risk assesment

Q

What does risk mitigation include?

A
  • Risk acceptance
  • Risk avoidance
  • Risk limitation
  • Risk transferance
17
Q

How can you engage stakeholders in risk analysis?

A
  • Sharing the outcome of a risk assesment
  • Discuss options for risk management
  • Promotion of risk management messages, through social media etc.
18
Q

What is a quantitative Risk Assesment?

A
  • Delivers a numerical result
  • More detailed and exacting
  • Demands reliable data
  • benefits from intervention
19
Q

What is a qualitative Risk Assesment?

A
  • No numeric estimate but has a ranked scale
  • based on opinion
  • relatively rapid
20
Q

What expertise is required for a risk assesment?

A
  • Experts on the hazard that is being evaluated
  • Experts with knowledge on the risk factors
21
Q

What is the approach for gathering evidence?

A
  • Organise a workshop with experts
  • develop a questionnaire requesting information on an estimation about the probability and consequence of each of the risks
22
Q

What is the deterministic model of a quantitative risk assesment?

A

parameters are defined as a constant

23
Q

What is the stochastic model of a quantitative risk assesment?

A

The value of parameters vary and is estimated to be different in every iteration

24
Q

What do you need to consider in a risk question?

A
  • Outcome
  • Hazard
  • Population
  • Time period
25
Q

How may you qualitively rank a risk?

A
  • Negligible
  • Very low
  • Moderate
  • High
  • Very high
26
Q

What is the difference between the stoichastic and deterministic model

A

The stoichastic model incorporates randomness and uncertainty into the modelling process

27
Q

What is the definition of uncertainty?

A

Facts that can be known with certainty but are not currently known by the observer

obtaining more information can reduce this type of uncertainty

28
Q

What is the definition of variability?

A

inherent varaibility in the physical world that cannot be known for certain
-this type of uncertainty cannot be reduced
