Principles of risk assessment
Legal background
Management Regulations (1999) are the
umbrella regulations
Require employer to:
•
•
•
•
Identify hazards
Assess risks
Eliminate or control exposure to risks
Write it down if significant
Principles of risk assessment
Risk Assessment – the 5 steps
• What are the hazards?
• Who is doing what, where & when? (WWW)
AND
Who else might be affected by what is done?
• What is the degree of risk?
• What do we need to, or can we, do to control
(eliminate/minimise) exposure to the risk?
• How will we monitor the work/people?
Principles of risk assessment
What comes first?
Even before the 5 steps – one question:
What is it we have/want/would like to do?
We can call this: • The task
• The job to do
• The procedure
Everything can be covered in this way
Principles of risk assessment
Let’s have some examples
Principles of risk assessment
Hazard and Risk
Hazard
the potential to cause harm or damage
Risk
the chance of that harm occurring
Calculated as -
potential severity of harm
(the consequence – or damage)
x
likelihood of event occurring
Principles of risk assessment
Hazard identification
• What will I be using/doing?
• How much do I know about what I am
using/doing?
• What factors or properties could there be that
affect the level of hazard (not risk)?
• Do I really have to do the work/task at all?
• Can I substitute something less hazardous?
Principles of risk assessment
Who is affected by the work?
• Those who do the work
•
•
•
•
•
•
•
•
•
•
Maturity
Experience
Health and immune status
Medication
Disability
Pregnancy
Others in the workplace
Cleaning and maintenance staff
Visitors
External – including neighbours
Principles of risk assessment
Can we work out how high the risk is?
Consequence - severity
• What could go wrong?
• What is the worst that could happen?
Likelihood
• How often must it be done?
• How many people do it?
• Is everyone doing it competent and trained?
Principles of risk assessment
How likely?
Where do our risks fit on the spectrum?
How bad?
Principles of risk assessment
Evaluating the risk
1. Highly unlikely
1. Slight harm
2. Possibly
2. Injury affecting work
3. Quite likely
3. Serious injury
4. Very likely
4. Possible fatality

Principles of risk assessment
Controlling the risk
Unacceptable
– stop doing it until
improvements made
Significant
- proceed with caution but
improvement high priority
Tolerable
- OK to proceed but plan to
improve
Insignificant
- Any improvements low
priority
Principles of risk assessment
Controlling the risk
• Decide measures to be taken
• Implement them according to priority
• Confirm measures appropriate and work
Principles of risk assessment
Monitoring and Review
Monitoring
• ‘Live’ nature of assessments
• Possible modification to procedures
Review
• Identifies changes to procedures
• Possible modification to assessment
