9. Risk Assessment
•Risk assessment is the process of
identifying and evaluating a hazard to
determine the level of action required to
reduce a risk to an acceptable level.
•It is nothing more than a careful examination
of what in the workplace could cause harm to
people, so that we can weigh-up whether the
department has taken enough precautions or
are required to take additional precautions,
to prevent harm occurring.
10. What is a Hazard?
-A Hazard is anything
that has the
potential to cause
harm, e.g.
chemicals,
electricity, working
up a ladder.
-Using a crane, forklift
…….
11.
12. What is a Risk?
-The Risk is the likelihood that the hazard will
cause harm and the severity of the
consequence.
-For Example:
*If you are cleaning the oven with corrosive
cleaner without using gloves or apron there is a
great risk of being harmed.
*If you wear all protective clothing and gloves
and adhere to all safety precautions the risk is
low.
*If you change the chemical to a safer type and
adhere to all precautions the risk will be even
lower.

14. Risk Assessment In Practice
Five Steps to Risk Assessment:
1-Look for the hazards
2-Decide who might be harmed and
how
3-Evaluate the risks and decide whether
the existing precautions are adequate
or whether more should be done.
4-Record your findings.
5-Review your assessment and revise it
15. 1-Hazard Identification
-Walk around the workplace and look afresh
at what could reasonably be expected to
cause harm.
-Previous Accident Reports
-Brainstorming
-Knowledge of Employees
-Material Safety Data Sheets (MSDS(
-Manufacturers Instruction Books
-Ask, “What If….?”
16. Continue
The following are examples of plant,
equipment or activities that are
usually associated with a hazard:
-Work at heights, and access to/from it
(roofwork, ladders, scaffolds(.
-Work below ground level and in confined
spaces (tanks, ducts, trenches(
-Manual handling of loads.
-Work with electricity (portable tools,
extension leads(
-Hazardous chemical substances.
17. Continue
-Display screen equipment.
-Ionizing, non - ionizing and laser radiation
-Pressure vessels / vacuum works
-Flammable liquid and gases
-Machinery and plant (machinery requiring
guarding(.
-Grinding/milling machines
-Woodworking machines.
-Portable power tools.
•-Noise
-Vehicles (forklift, cranes(
-Disposal of special wastes.
18. List of Hazards
-Slipping/tripping
hazards (poorly
maintained floors or
stairs(.
-Fume (from welding(
-Dust (from grinding(
-Manual handling
-Poor lighting
-Temperature
-Electricity (poor
wiring(
-Ejection of material
(from plastic molding(
-Chemicals (battery
acids(
-Pressure systems
(steam boilers(.
19. 2-Who Might Be Harmed and How
-Generally it will be staff occupying the
workplace.
-Attention must be paid to:
*Visitors
*Contractors
*Cleaning staff
*Maintenance staff
*Inexperienced staff
20. LikelihoodLikelihood
Very Likely: Could happen Frequently
Likely: Could happen occasionally
Unlikely: Could happen, but only rarely.
Likelihood: The chance of an event
(which may cause injury or harm to
person( actually occurring.
Highly Unlikely: Could happen but
probably never will.
21. Exposure
When evaluating the likelihood of an
accident, a factor that will modify the
likelihood category, is exposure.
•Exposure:
Is a measure of how often or how long a
person is actually exposed to a hazard,
some examples are:
22. Continue
Very Rare: Once per year or less.
Rare: A few time per year.
Unusual: Once per month.
Occasional: Once per week
Frequent: Daily
Continuous: Constant
23. Consequences
Consequence is a measure of the expected
severity should an accident occur.
1-Fatal: Death
2-Major Injuries: Normally irreversible injury or
damage to health requiring extended time off
work.
3-Minor Injuries: Typically a reversible injury
or damage to health needing several days
away from work to recover.
4-Negligible Injuries: Would require first aid
and may need the reminder of the work
period or shift off before being able to return
to work.

25. Risk Control
-When a risk assessment has identified a
hazard as having unacceptable risks we
have to put in place control measures to
eliminate the risk or reduce the risk to an
acceptable level.
