3. What is Risk?
The Chinese symbol for risk is a combination
of both danger and opportunity
Risk = P(undesired event) x Consequence
In finance, risk is the variability of actual
returns around the expected return
4. What is a risk assessment?
oIt is a way of determining
risks and dangers in work
places.
5. What is a risk assessment?
oRisk assessments include analysing
the possible hazard that could
occur within a workplace and
finding a solution in a safe manner.
This avoiding injury to an
individuals and damage to
property.
6. What is a risk
assessment?
oIf the hazard cannot be avoid in
a safe way, then the risk
assessment will say that the
activity shouldn’t be carried
out.
7. How does a risk assessment work?
When carrying out a risk assessment
there are 5 recommended guidelines.
1.Identifying the hazard:
2.Decide who might be harmed and
how.
3.Evaluate the risks and decide on the
precautions.
Billie-Jean Davis and Emma Jones-Bennett
8. How does a risk assessment work?
4. Record your findings and put
them into place
5. Review you risk assessments and
make amendments if needed.
A risk assessment should be carried
out yearly.
Billie-Jean Davis and Emma Jones-Bennett
9. Step One: Identifying the hazards.
Within the lab there would be many
possible hazards.
So these would need to be quickly
identified before they can cause harm
to anyone.
• Firstly you would need to know what
can be classed as hazardous before
identifying hazards.
10. Step One: Identifying the hazards.
•Look around for any chemicals that
may cause harm and any equipment
that may be faulty or be in a place
where it could get in someone's way.
•You would also have to think about any
long term hazards there may be.
11. What is Hazard?
•Anything (material/substance,
machine, methods or matters) in
the workplace that has the
potential to cause harm.
12. CATEGORIES OF HAZARD
• Safety – anything or condition
that can cause physical injury.
• Health – any infective agent,
substance situation or condition
that directly attacks the body
tissues causing occupational
illness.
13. CATEGORIES OF HAZARD
• Environment – any pollution,
waste including noise in any
form or quantity that impairs the
quality of the working
environment, such as dust,
smoke, gases, radioactivity and
odors .
14. CATEGORIES OF HAZARD
• MAN MADE HAZARDS-caused
by people
• NATURAL HAZARDS-caused
by nature like typhoons or
earthquake.
• FINANCIAL-affected by
business tycoons, they control
the price of the products.
15. CATEGORIES OF HAZARD
Anticipate “ Bankruptcy” by:
(1)Analyzing the financial
statement of the company.
(2)Preparing a study.
(3) Identifying Labor Cost.
(4) Knowing your competitors.
17. Step 2: Decide who might be harmed
and how .
• Think about the possible health
risk or injury that could be caused
to an individual.
• Take into account any workers
that may have special health and
work requirements.
18. Step 2: Decide who might be harmed
and how .
•Think about new workers
that work within the
laboratory as they may not
know the way the
equipment works.
19. Step 2: Decide who might be harmed
and how .
•It needs to be taken into
account about how the
laboratory activities can
affect the public.
20. Step 3: Evaluate the risks and decide
on the precautions
•After spotting the
hazard decide on the
actions that would need
to be taken.
21. Step 3: Evaluate the risks and decide
on the precautions.
•When this has been done you
would need to do anything
reasonable practical that would
eliminate the risks of the
hazard occurring.
22. Step 3: Evaluate the risks and decide
on the precautions.
• If there is no way of eliminating
the hazard happening then a
precaution would need to be
taken to control the risk to the
best ability i.e. try and carry out a
less risky activities.
23. Step 4: Record your finding and put them into
place.
• Once the results are recovered for
the risk assessment then all staff
within the laboratory should be
informed.
• When writing out a risk
assessment results it needs to be
kept simple and understandable.
24. Step 4: Record your finding and put them into
place.
• A risk assessment do not need to
be perfect but it needs to show
that an inspection has been
carried out correctly and that
precautions are reasonable leaving
the risk to a minimum.
25. Step 5: review your risk assessment and make
amendments if necessary
• Make sure that the risk
assessment is correct, and that all
hazards have been covered and
included. Make sure that the
people are safe to work within the
laboratory.
26. Step 5: review your risk assessment and make
amendments if necessary
• If hazards occur later on (after a risk
assessment has been conducted) then
changes will need to be made to that
risk assessment.
• A risk assessment should be carried
out yearly to minimise the risks within
a laboratory.
27. What is the difference between hazard and
risk?
28. The Process of Risk Management
Classify Activities
(Work, Product, Services)
Identify Hazard
Assess The Risk
Risk Control
Review Risk Control
29. Classification & Potential Sources
of Hazards
Classification Example of Hazards
• Mechanical - Sharp points & edges, overload.
• Electrical - Insulation damaged or cover
broken.
• Biological - Exposed, airborne/blood borne
• microorganism.
• Chemical - Expose to carcinogens chemical.
• Ergonomics - Expose to unnatural postures.
• Psychological- Stress or violent at workplace.
30. MANAGEMENT OF
HAZARDS
All aspects of the workplace
should be covered by a general
risk assessment process that
will reveal the significant
hazards present and the control
measures in place.
31. MANAGEMENT OF
HAZARDS
Risk is:
“The likelihood of a substance,
person, activity or process to cause
harm (injury or illness)”
Risk can be reduced, hazards are
controlled by good management.
33. HAZARD REDUCTION
STEPS
3. CONTROLS
Decide whether the existing precautions
are adequate or more should be done.
4. MONITORING and
REVIEWING
Periodic checking for continuous
improvement.
34. ASSESS AND EVALUATE THE
HAZARDS
“consider its severity(consequences) probability
and exposure”Once identified, determine how harmful the
hazard can be;
• The likelihood to cause harm
• Under what conditions it can occur?
• What type of harm can occur?
• Who or how many workers can be harmed?
• What may be the extent of the harm or injury?
• Is there a history of problem, accidents or dangerous
occurrence from the hazard?
• What monitoring is needed to evaluate the risk?

39. A hazard is anything that may
cause harm such as chemicals,
electricity, working from height
or machinery.
40. A risk is the chance, high or low that
someone could be harmed by a
hazard together with an indication
of how serious the harm
could be.

Risk versus probability - The probability of the event occurring and the consequences of the event. Thus, the probability of a severe earthquake may be small, but the consequences are so catastrophic that it would be categorized as a high-risk event.
Risk versus threat - A threat is a low-probability event with large negative consequences, where analysts may be unable to assess the probability. A risk, on the other hand, is defined to be a higher probability event, where there is enough information to assess both the probability and the consequences.
All outcomes versus negative outcomes— Some definitions of risk tend to focus only on the downside scenarios, whereas others are more expansive and consider all variability as risk. The engineering definition of risk is defined as the product of the probability of an event occurring, that is viewed as undesirable, and an assessment of the expected harm from the event occurring.
