RISK ASSESSMENT
� Risk Analysis
Hazard Identification
Risk Estimation

STAREGISTER PAKISTAN
RISK ASSESSMENT
The process of establishing information regarding acceptable levels of a
risk and/or levels of risk for an individual, group, society, or the
environment.
(OR)
Overall process of estimating the magnitude of risk and deciding Overall process of estimating the magnitude of risk and deciding
whether or not the risk is tolerable.
Before undertaking any task, always identify the hazards and assess
the risks. Then implement the measures required to remove or
minimise the risk before starting work.
STAREGISTER PAKISTAN
FORMAL RISK ASSESSMENT
� Identification
Risks categorized as affecting Confidentiality, Integrity, or
availability
� Prioritization
Risks are prioritized by their impact, and probability
STAREGISTER PAKISTAN
FORMAL RISK ASSESSMENT
� Controls
Controls are identified and recommended based on the risks
identified. Controls are prioritized based on cost, priority, and
capability to implement.capability to implement.
� Report
A report is prepared by the facilitator and approved by the team.
STAREGISTER PAKISTAN
OVERALL RATING OF RISK
The overall risk is determined as per below mentioned formula:
Risk = Likelihood X Effect on health
R = L x H � R = L x H
Risk rating 9 and above should be considered un-tolerable risk
and needs to be controlled.
STAREGISTER PAKISTAN
OVERALL RATING OF RISK
� A casual definition of Risk is
Risk = P * S
Where P is the probability of occurrence & S is the severity of an event
� Risk = ¦{ hazard, exposure, safeguard}
STAREGISTER PAKISTAN
OVERALL RATING OF RISK
This will help us in answering:
-- How likely is an event to occur?
-- What likely are the effect (consequences)?
Risk = frequency * consequence
STAREGISTER PAKISTAN
EXAMPLE
If we can’t take away the Hazard we shall have to reduce the riski.e. Reduce the frequency and/or reduce the consequence
For this we need to firstEstimate the frequency and/or estimate the consequenceEstimate the frequency and/or estimate the consequence
EXAMPLE: 1 Risk on a Cricket FieldSohaib Akhtar is the bowler : He is the HazardYou are the batsman : You are at riskFrequency = 6 times per over. Consequence = bruises!
Risk = 6 X bruises!
Risk reduction : Limit bounces to 2 per hr. Wear more padsRisk = 2 X small bruises!

ACCIDENT REPORTING AND INVESTIGATION INVESTIGATION
STAREGISTER PAKISTAN
ACCIDENT DEFINITION
An accident is an unplanned/unpremeditated event caused by
unsafe acts or conditions which results in a loss.
STAREGISTER PAKISTAN
NEAR MISS (INCIDENT)
� A near miss is an unplanned/unpremeditated event that has the
potential to cause injury to people or damage to property.
� IMMEDIATE / DIRECT CAUSES
� The immediate/direct cause is the unsafe act or condition that
results in an accident or incident.

ROOT / UNDERLYING CAUSES
The Root (Underlying) cause is the failure of procedure /
management systems that have resulted in the unsafe act or
condition.

accidents and can therefore produce more data from which a
greater understanding of the deficiencies in management
systems can be identified and rectified
