Risk Assessment and Job Safety Analysis I JSA

1. Risk Assessment & Job
Safety Analysis

2. 2
Majority of accident that happens in the construction site
is due to the fact that more personnel involved in the
construction activities lack the basic knowledge of the
various job step, the hazards and the control measures
for each hazard
The Work Method of Statement, Risk Assessment & Job
Safety Analysis (JSA) will cover this gap by giving the
people the necessary training, information etc… about
each job (task) and how to carry it out without accidents
Introduction

3. 3
JSA
⚫ JSA shall be conducted during;
➢ Critical task
➢ Non-routine Task
➢ Permit To Work Task
➢ Routine Task (Daily/pre-task)
⚫ Every work activities shall have a corresponding Work
Method of Statement prepared by the task Supervisor or
task Manager.
⚫ Risk Assessment shall be done with respect to the
corresponding hazard that will be analyzed and mitigating
measures during job hazard analysis.
⚫ JSA will be conducted to break down each job steps into
safe more detailed procedures.

Risk Assessment is an extremely useful tool in
providing a framework in which to identify the potential
hazards & evaluate the risks associated with all our
activities.
Risk Assessment now forms a routine element in
education & training within the Project.
Risk Assessment

5. 5
To prevent workplace injury, disease & property
damage, it is necessary to identify the cause of
accidents
• This can de done:
➢ Reactively by accident investigation, or
➢ Proactively by carrying out risk assessments
• Risk assessment enables the identification of those
events or activities, which could cause harm &
evaluation of the associated risks.
Risk Assessment

6. 6
IDENTIFY POTENTIAL LOSS
• Risk Assessments involve addressing the following
questions:
➢ What could go wrong?
➢ How likely are such events?
➢ What would happen if such events occurred?
➢ What are the associated risks?
➢ Are the risks acceptable?
➢ How can the risks be reduced...or removed?
Risk Assessment

7. 7
• There is confusion in the interpretations of familiar words
such as accident, hazard, risk & danger and so on;
• Different sources of information put similar but different
interpretations on these expressions or terms
• So for the purpose of discussing risk assessment the
following conditions apply on the Project:
1. RISK ASSESSMENT
This is the process of identifying hazards and assessing
the risk of harm and loss threatened by the hazard.
Definition

8. 8
2. RISK MANAGEMENT
Risk Management in its broadest sense represents the
successful control of all threats of harm and loss to an
organisation, group of people or an individual
3. QUANTITATIVE RISK ASSESSMENT
This type of assessment produces numerical values of
the risk involved and evaluates the results against
specified risk criteria.
4. DANGER
Danger is a state or situation, which is a product of a
hazard and it’s associated risk.
Definition

9. 9
5. ACCIDENT
An accident is commonly defined as an unplanned
event, which result in Injury or Damage.
6. INCIDENT
An incident is an event, which represents deviation from
the intended sequence of designed steps. Commonly
defined as an unplanned event, which does not result in
Injury or Damage A “Near Miss” is by definition an
Incident.
7. RISK
A risk is the likelihood that harm may result being a
function of both frequency and severity. The risk can
range from the trivial (a paper cut) to catastrophic
accident
Definition

10. 10
8. SAFE OR SAFETY
Often thought of as representing the level of security and
freedom from harm.There is no such thing as complete
safety, an appropriate definition might be “the maximum
level of risk a person or organisation is prepared to accept”
9. HAZARD
A hazard is something with the potential to cause harm.
This can be substances or machines, methods of work and
other aspects of work organisations
10. Harm
Harm represents physical injury, death, ill health, property
and equipment damage and any from of associated loss
Definition

12. 12
GENERIC RISK ASSESSMENT
A generic or group assessment is a general
assessment of the risk posed by a combination of
discrete or separate risks of varying type & severity.
The risk assessment process can be managed more
efficiently by producing generic risk assessments that
are applicable to as many people or places as possible
SPECIFIC RISK ASSESSMENT
Some specific hazards where a generic risk
assessment has not been carried out, or where it is not
considered suitable or sufficient, then a specific risk
assesment should be made.
Risk Assessment Process

13. 13
Safe Place
Strategies
1. Eliminate the Hazard – the very
best thing to do if possible
2. Reduce the Hazard
3. Isolate Hazard from people
4. Control the extent of
exposure/contact with the hazard
5. Personal Protective Equipment
(PPE) almost the last resort
6. Discipline
Hierarchy of Control
Safe Person
Strategies

14. 14
STAGES
1. Identify & analyse all tasks
2. Identify hazards that are, or may be involved
3. Identify those who may be exposed to the hazards
4. Analyse the risks of injury or loss from hazards
5. Evaluate if the risk is adequately controlled (consider
existing control measures)
6. Monitor & review
Risk Management Process

15. 15
METHODS OF HAZARD IDENTIFICATION
• Accident Investigations
• Safety Survey or Safety Tours
• Communication (Tool Box Talks etc)
• Job Safety Analysis (JSA)
• Special Risk Assessment techniques such as:
➢ Hazard Operability Studies (HAZOPs)
➢ Quantified Risk Assessment (QRA)
➢ Hazard Operability Studies (HAZIDs)
Stage Two – Identify Hazards

16. 16
• Workforce directly involved in activity
• Other employees personnel
• Visitors
• Members of the public
Stage Three – Identify People at Risk

17. 17
The purpose of the Risk Analysis stage is to obtain an
idea of the size or the scale of the risk.
Put simply,
A Risk Assessment is finding out what could cause harm
to people (Environment, Task or Equipment)
and deciding if we have done enough, or need to do
more to protect them,
or better still to ensure we meet the Project H&S Policy
that all risks are As Low As Reasonably Practicable
(ALARP)
Stage Four – Risk Assessment

18. 18
QUALITATIVE TECHNIQUES
Where risk is expressed in terms of High, Medium or Low
QUANTITATIVE TECHNIQUES
Attempt to express risk in numerical terms & will be based on
calculation using data of failure rates of equipment, human
error, etc
RISK EVALUATION
Risk evaluation is determined by the Likelihood of the incident
event occurring multiplied by the Severity of the incident
LIKELIHOOD X SEVERITY = RISK
Stage Four – Risk Assessment

19. 19
Risk Assessment Matrix

20. 20
LIKELIHOOD POTENTIAL is determined as follows:
E - Happens several time per year in this project – could happen at
any time
D - Happens several time per year in our Corporate – could happen
sometimes
C - Incident has occurred in our Corporate – could happen, but very
rarely
B - Heard of in construction industry – could happen, but probably
never will
A - Never heard in construction industry – theoretical
Risk Evaluation - Likelihood

21. 21
Risk Evaluation - Severity

0 No injury or damage to health.
1 Slight injury or health effects (including First Aid case
and Medical Treatment case and Occupational illness)
- Not affecting work performance or causing disability.
2 Minor injury or health effects (Lost Time Injury )
-Affecting work performance, such as restriction to
activities (Restricted work Case or Occupational
Illness) or a need to take a few days to fully recover
(Lost Workday Case). Minor health effects, which are
reversible, e.g. skin irritation, food poisoning.

22. 22

induced hearing loss, chronic back injuries, sensitization,
hand/arm vibration syndrome, repetitive strain injury.
4 Permanent Total Disability or one to three fatalities
- from an accident or occupational illness.
Irreversible health damage with serious disability or death,
e.g. corrosive burns, heat stroke, cancer (small exposed
population)

What Is Job Safety Analysis
⚫ It is the breaking down of a particular task into steps
to be taken in a sequence
⚫ Exposing the hazards involved in each of the steps
⚫ Putting in place control measures for each of the
hazards
⚫ Considering the PPE requirement for each step

30. 30
Purpose of JSA
⚫ To improve understanding and safety
⚫ To ensure that there is a written, and approve Work
Method of Statement for every job on site
⚫ For proper control of safety on the job

31. 31
Benefits of JSA
⚫ Supervisors learn more about the jobs their
subordinates perform and how better to manage
them.
⚫ When regularly performed, developed safe work
practices reduced employee injuries.

32. 32
Five Basic Steps
⚫ Select job to be analyzed
⚫ Break job down into it’s smallest steps
⚫ Identify hazard associated with each steps
⚫ Develop control measures to eliminate hazards
⚫ Monitoring and periodic reviews

33. 33
Job Safety Analysis Training
⚫ All new employee should be aware of the various
step involved in their operations.
⚫ Let employees learn how to perform a job efficiently
and safely.
⚫ Supervisors shall clearly explains to his subordinates
all the proper steps in doing the task safe

Job Safety Analysis (JSA)

35. 35
• Keep it simple
• Developed (at least in part) by the personnel
performing work
• We believe that JSA should be a thoughtful process
... Not simply a form to complete.
• JSA must be reviewed with all personnel coming on
shift
• OK to use previously developed JSA, but must be
upgraded based on current scope and conditions,
and actively reviewed by the crew
• For jobs that are repetitive, review and upgrade
JSA before starting the work.
Job Safety Analysis Guidelines

36. 36
• When work is already completed, update the JSA to
identify lesson learned and unexpected results
• Update the JSA if an accident or near-miss occurs
• Ask for feedback each day consider new ideas and
include in the JSA form
• Include job setup and demobilization in the JSA
• A JSA should;
➢ Identify the location of the work to be performed
➢ Address how the job may affect others
➢ Address emergency situation
➢ Identify communication requirements
Job Safety Analysis Guidelines

37. 37
• When work is complete, why not update the Pre-task
Safety Plan to identify learnings and unexpected results
Update the Pre-task Safety Plan if an accident or Near
Miss occurs
• Ask for feedback each day – consider adding a place
for it on the form
• Include job setup and demobilization in the Pre-task
Safety Plan
Job Safety Analysis Guidelines

38. 38
How is it done at your site?
• Is it similar?
• Is it truly different?
• Is it effective? (How do you verify?)
• What are your success stories?
• What are your challenges?

39. 39
• Few accidents occur during extremely hazardous
operations because we are fully aware of the risk
• Most accidents occur during routine, repetitious jobs
because we become complacent
• Therefore, all supervisors are expected to insure
effective Risk Assessment and JSA are conducted
and all their crews will follow all the provisions in the
form. Supervisor should make sure that pre-task
meeting is conducted before beginning each work.
