Applying a Risk Engineering Framework
to Fatigue Safe Systems
Risk engineering frameworks focus
on:
- hazards
- triggers
- effects
- safeguards
- Residual Risks
- Assessment of Systems Integrity
Risk engineering disciplines are
based on a systematic and comprehensive
identification of threats, the
design of adequate safeguards
and assessment of current and
future risk profiles.
Organisational Fatigue Risk Grading
Risk engineers use risk grading
systems to objectively rate the
adequacy of current or future
controls to protect against inherent
exposures. The benefits of risk
gradings include;
- a consistent world wide risk
assessment
- benchmark data on risk levels
- cost benefit comparisons
- prioritisation of risk reduction
investments
They can assist organisations to
answer the question "are
we fatigue safe" by identifying
critical control points that can
lead to unacceptable risks.
Risk Grading systems are typically
based on predetermined definitions
for each grading element and risk
level factor, a systematic assessment
of pure risks and often as many
as 15 to 30 grading elements.
The overall risk grading is determined
using a weighted average formula
based on (claims) experience over
many years and industries.
Whilst an absolute answer to the
key question "are organisations
fatigue safe" is always going
to be elusive, organisations are
now able to seek assistance from
risk engineers to help them identify
unacceptable fatigue risk levels.
Fatigue Risk Grading System -
Graid®
idZRE is a global alliance of InterDynamics
(id) and Zurich Risk Engineering
(ZRE). ZRE have been drawn to
InterDynamics because of the 'holistic'
nature of InterDynamics Faid®Safe
organisational fatigue risk management
service, which has gained extensive
experience in the identification
of fatigue related exposures and
controls to a level not seen anywhere
elsewhere in the world. The alliance
has developed an Organisational
Fatigue Risk Grading system based
on predetermined definitions for
each grading element and risk
level factor, a systematic assessment
of pure risks and incorporating
25 grading elements. The purpose
of this system is to provide an
objective rating of the adequacy
of current and future safeguards
to protect against inherent exposures.
Grading Overview
Grading
The grading tool is for risk assessment.
It is made up of the various risk
factors for assessing perils resulting
in an overall Grading that indicates
the quality of the risk.
Who uses the grading?
Gradings should be used by risk
engineering professionals in assessments
for global customers and local
services.
Type of grading
There are or will be gradings available
for all important lines of business
serviced by Zurich Risk Engineering
including initially Fatigue Risk,
Capacity Risk and Supply Chain
Interruption Risk.
Why use grading?
The benefits of risk gradings include
a consistent world wide risk assessment,
benchmark data on risk levels,
cost benefit comparisons and prioritisation
of risk reduction investments.
Purpose of grading for
Risk Engineering
- Performing the risk assessment
process in a structured way
- Supporting risk engineering
professionals with given risk
factors and defined risk assessment
criteria
- Increasing consistency
- Providing results which are
transparent to customers
- Providing results that can
be used for underwriting purposes
Grading Principles
Relative vs Absolute Assessments
The grading is built on the principle
of the relative assessment. This
means that the risk assessment
criteria are different for each
type of industry.
Grading Calculation
The result of the Grading is called
"Overall Grading". It
is calculated based on the assessment
results of a set of risk factors.
Risk factors are determined by
a risk factor based on risk assessment
criteria.
ZRE Graid® Scores
The Zurich Risk Engineering linkage
is emphasised by promoting a "ZRE
Graid® score" to indicate
the quality of the risk.
e.g. 1. "a ZRE Fatigue Graid®
score of 130"
- means a "FAIR" Organisational
Fatigue Risk Grade which has been
assessed by a certified Zurich
Risk Engineering Professional.
e.g. 2. "a Fatigue Graid®
score of 80"
- means a "GOOD" Organisational
Fatigue Risk Grade which has been
assessed by an individual or organisation
who is not a certified Zurich
Risk Engineering Professional.
