Hazards
10
Why do we need to manage Hazards?
 It's a legal requirement - compliance with the legislation!
 Keep workers safe from health risk while they at work.
 Prevent exposing others, plant and the environment to harm.
 Comply with company policy and procedural requirements.
 Promotes a safety culture at the workplace!
 Demonstrates that a business is committed to addressing health and
safety issues.
 Good business sense, it reduces financial risk.
 Morally, it’s the right thing to do!
11
Who has a Duty?
Under the South Australian WHS Act 2012:
S.17 - Management of risks
A duty imposed on a person to ensure health and safety requires the
person:

to eliminate risks to health and safety, so far as is reasonably practicable,
and

if it is not reasonably practicable to eliminate risks to health and safety, to
minimise those risks so far as is reasonably practicable.
A person must comply with the above to the extent to which the person has
the capacity to influence and control the matter
12
Who has a Duty?

take reasonable care his or her acts or omissions (actions or words), do
not adversely affect the health & safety of other persons.

comply, so far as the worker is reasonably able, with any reasonable
instruction designed to protect their health and safety and, that of any
other persons while at work.

co-operate with any reasonable policy or procedure relating to health or

17

eliminate risks to health and safety, so far as is reasonably
practicable

where it is not reasonably practicable to eliminate risks to health and
safety, to minimise those risks so far as is reasonably practicable.
Reasonably Practicable
What is “Reasonably Practicable” in ensuring health and safety?
Reasonably Practicable in relation to a duty to ensure health and safety,
means:

that which is, or was at a particular time, reasonably able to be done in to
ensuring health and safety.
This includes, taking into account and weighing up all relevant matters
about:
18

the likelihood of the hazard or the risk concerned occurring.

the degree of harm (injury or damage) that might result from the hazard or
the risk.

hazard or the risk; and ways of eliminating or minimising the risk.
Reasonably Practicable
This also includes:

the availability and suitability of ways to eliminate or minimise the risk.

after assessing the extent of the risk, ways of eliminating or minimising
the risk, the costs associated and including, whether the cost is grossly
disproportionate to the risk.

Hazard ID & Risk Management Process
1. Identifying hazards
24

The first step in managing risk to health and safety in the workplace is
identifying hazards.

Identify all regularly performed tasks / work along with any plant,
equipment, substances and environment that is used or occupied.

Systematically and visually observe each task being undertaken to
determine if there are any hazards and document them.

For tasks / work that is not regularly performed, a job hazard analysis or a
safe work method statement (construction work) must be completed
Areas to Consider
Additionally, hazard identification must also be carried out before & during
introduction of new plant or undertaking a new task i.e. maintenance or
cleaning.
Consideration should be given to:
25

hazardous substances exposure (silica, asbestos, chemicals)

design or layout of the workplace.

potential to crush, puncture, stab or burn to the operator.

actual or intended use of plant or equipment or potential misuse.

noise and electricity.

potential to bypass safety interlock systems.

ergonomics / hazardous manual tasks.

potential for falling objects.

working alone / isolated work.

before and during alterations to plant or associated systems of work.
Risk
The probability & consequences of the level of harm or damage occurring

Risk Assessment
Risk Assessments MUST include one or more of the following:
27

a visual inspection of the task / work.

formal documented risk assessment.

discussions with designers, manufacturers, suppliers, importers,
workers or any other relevant parties.

testing (noise levels).

measurement (silica levels).

a review of incident of harm and near miss data.
Hazard ID & Risk Management Process
2. Assessing the risk
Once the task / work and associated plant, equipment, substances and
environment have been viewed and hazards have been identified, they must
be risk assessed for the risk they pose to a workers health and safety.
Using a risk matrix, determine the level of risk by assessing the:

exposure (how frequently a worker or thing is exposed to a hazard).

likelihood (chance) of harm occurring, and

most likely consequences (injury or damage) if harm was to occur.
Calculating these 3 factors will give you a risk rating score and determine
whether there is an extreme, high, moderate or low risk to a workers health
and safety .
Once you have determined the risk rating for each hazard, you can then
proritise the order of hazards to be addressed, by starting with the highest
level of risk first .
28
Risk Matrix
Risk Matrix
Exposure (E)
How frequently a person(s)
will be exposed to the
hazard
Likelihood (L)
The Likelihood that harm will
occur if exposed to the
hazard
Consequence (C)
The most likely
consequence if harm does
occurs
E x L x C = Risk Level
Continuously = 10
Constant exposure to the
hazard during a shift
Almost Certain = 1.0
Harm is expected to occur if
exposed to hazard
Catastrophic = 20
Injury resulting in a fatality
Extreme = a score more than 20
Stop work until a risk control has been
implemented
Frequently = 6
Exposure to the hazard occurs
several times during a shift
Likely = 0.6
Harm will probably occur if
exposed to hazard
Occasionally = 3
Exposure to the hazard occurs
once a shift
Possible = 0.3
Harm could occur if exposed to
hazard
An injury (excluding
hospitalisation or death) that
requires professional medical
treatment.
Infrequently = 2
Exposure to the hazard occurs
once over several shifts
Unlikely = 0.1
Harm is not likely to occur if
exposed to hazard
Minor = 2
Minor injury that only requires
first aid
Major = 10
Injury requiring
hospitalisation
High = a score between 10 & 19.9
Implement risk control within 3 days
Significant = 5
Moderate = a score between 3 & 9.9
Implement risk control within 1 week
Low = a score less than 2.9
Regularly monitor the hazard
Rarely = 1
Exposure to the hazard may
occur but unlikely
29
Rare = 0.05
Harm may occur only in
exceptional circumstances if is
exposed to hazard
Insignificant = 1
No injuries
Areas to Consider
When assessing risk, consideration must be given to:
30

the nature of the hazard.

how it may impact on health and safety.

how workers are exposed.

the amount, frequency and length of exposure.

the way work is organised.

layout and condition of work environment.

training and knowledge.

type and condition of control measures available.
Areas to Consider
Additionally, a risk assessment must be conducted when:
31

Planning – projects, work or activities

Designing

Commissioning / de-commissioning

Before the introduction of new work, activities or tasks

Before the buying of plant, substances or other goods and services

Changes to how work is done

Changes to legislation, standards, manufacturer or supplier
information
Hazard ID & Risk Management Process
3. Controlling the risks

Control measures are used to manage risks and are ranked using the
hierarchy of control.

This ranking sets out what control measures give the highest level of
protection and reliability to the lowest.
The greater the risk, the higher level of protection required
32

Elimination of the hazard is always the first option, however, where this is
not possible, implement control measures to minimise risk of harm (injury
or dmage) to the lowest possible risk rating

As you work down the hierarchy, the controls become less effective and
require more monitoring and supervision.

Often a mixture or range of controls are put in place
Hierarchy of Control
Elimination
remove the hazard from the workplace
Substitution
Eliminates
or Controls
the Hazard
or Risks
use a different (safer) process, machine or chemical
Isolate
as much as possible, isolate the hazard or hazardous
work practice from people
Engineering
install guards on machines, put in
barriers around hazards
Relies on the
person
working with
the hazards /
risks ‘doing
the right
thing’
33
Administrative
use policies,
training & signs to
warn workers
PPE
Areas to Consider
Other control measure considerations:
34

what is already available?

is it practical?

does it reduce risk to an acceptable level?

does it introduce another level of unintended risk or hazard?

what is the cost?

is it acceptable to workers, is it going to work?
