5. Objective
The objective of this session is to explain:
 What a Job Hazard Analysis (JHA) is
 When a JHA should be used
 The benefits of a JHA
 JHA roles and responsibilities
 The JHA process
 How to fill out a JHA
 JHA requirements.

6. JHA – What is it?
 A JHA is a simple risk management tool used to ensure
a job or task is performed safely.
 It is a more detailed analysis of hazards and risks than a
Take 5 or workplace inspection.
 It is written by the people performing the task (team risk
assessment).
 Is it reviewed by supervisor(s) prior to the
commencement of work.

7. JHA – Terminology
Hazard
Anything which has the potential to cause harm.
Control
Anything that helps to reduce or eliminate the risk
presented by the hazard.
Risk
Combined measure of the consequence (severity of harm)
and the likelihood presented by the hazard.
7

8. Levels of Risk Assessment
8
Take 5 or Workplace Inspection Level 1
JHA Level 2
Formal Risk Assessment Level 3

9. Benefits of JHAs
 Improves job planning
 Identifies hazards associated with task
 Identifies controls for managing hazards - thereby
eliminating or minimising risk of harm
 Provides a review process to ensure line management
are aware of moderate and high risk tasks being
performed
 Assists employees to understand risk management
 Demonstrates a structured process for managing risk
 Keeps people safe.
9

10. JHA - When must one be done?
 When a Take 5 or workplace inspection identifies
hazards that are complex, high risk or can’t be readily
controlled
 When there is no written procedure or safe work
procedure for the task
 When work permits are required (e.g. confined space)
 Where there are deviations from standard work
practices
 If new hazards are identified or the task changes
 When existing risk controls are unclear
 As the first step in developing a safe work procedure.
10

11. JHA Roles and Responsibilities
Supervisors
 Confirm tasks that require JHAs
 Discuss JHA requirements at pre-start meetings
 Assign a competent JHA team leader to lead the
development of JHAs
 Review the JHA prior to tasks commencing
 Involve managers where necessary to review JHAs.
11

12. JHA Roles and Responsibilities
Team members
 Identify tasks that require JHAs
 Participate in the development of JHAs
 Follow JHAs
 Stop work if the task requires steps not covered in the
JHA.
12

13. JHA Process
Step 1 : Complete task details
Step 2 : Decide job steps
Step 3 : Identify hazards
Step 4 : Identify existing controls
Step 5 : Identify risk rating
Step 6 : Identify and implement additional controls
Step 7 : Approval and review.

14. Number of steps for each job or task
How are the number of steps required for each task
determined?
We will use the example of changing a flat tyre showing too
many steps, too few steps and about the right number of
steps………
14

15. Changing a Tyre – Too Many Steps
1. Pull off road
2. Put car in ‘park’
3. Apply hand brake
4. Activate emergency
hazard lights
5. Open door
6. Get out of car
7. Walk to boot
8. Put key in lock
9. Open boot
10. Remove jack
11. Remove spare tyre
12. Etc………………..
15

16. Changing a Tyre – Too Few Steps
1. Park car
2. Take off flat tyre
3. Put on spare tyre
4. Drive away
16

17. Changing a Tyre – Just Right
1. Park car, apply brake
2. Remove jack and tyre from boot
3. Loosen wheel nuts
4. Jack up car
5. Remove tyre
6. Fit new tyre
7. Jack down car
8. Tighten wheel nuts
9. Store tyre and jack
17

18. JHA Key Points!
3 Key points!
1. Break task into STEPS
2. Identify HAZARDS
3. Implement CONTROLS to reduce or eliminate the
RISK
18

19. JHA – Requirements
 The JHA must be read, understood and signed by all persons
doing the job before starting work.
 Supervisor must review and sign the JHA before work commences.
 All personnel, and both supervisors, must sign on to the JHA for a
job that takes longer than one shift.
 Area manager must review the JHA where the risk rating is
assessed as high or above.
 If the job changes, or the nature of the hazards change, then the
JHA should also be changed.
 Completed JHAs should be retained by each department for future
reference.
 Higher level of risk assessment required if uncertain of extent of
risk or adequacy of controls.
19

20. JHA – Requirements
 The JHA must be developed by two or more people involved with
the task.
 All personnel working on the task must have access to the JHA.
 A JHA can remain valid for a maximum of 30 days from the
approval date (providing that the conditions do not change).
 The same JHA can not be used more than once.
 Ideally if a JHA is going to be used more than four times a year
for the same task then a safe work procedure should be
developed.
 The work site should be visited to help identify any potential
hazards and ensure that the task is understood by those
developing the JHA.
 The hierarchy of controls should be used with the aim of using the
strongest and most effective controls.
20

21. JHA – Important Points
JHAs do not require as much detail as a safe work
procedure (e.g. photos / diagrams).
They are a tool for:
 Breaking a task into steps to understand the hazards
and implement effective controls
 The development or review of a safe work procedure
 Implementing effective controls for hazards introduced
when work practices / conditions change.
Workgroup involvement provides ownership!
Your JHA can keep YOU safe at work.
