3. 3
What is JHA?
A tool that focuses on job tasks as a way to
identify hazards BEFORE they occur.
Looks at potential hazards caused by:
– The task
– The tools or equipment used
– People – (the worker or management)
– The environment
– Material
AND, how the hazards can be eliminated or
reduced.

4. Sometimes Called
Accident Hazard Analysis (AHA)
Job Safety Analysis (JSA)
Task Safety Analysis (TSA)
4

5. A job is a task, not a
title!
5

6. Benefits of a JHA
Organized, systematic approach to Indentify
hazards
Indentify hazards, causes, and corrective actions.
Involves employees – increase their awareness
Standardizes operations based on acceptable safe
practices
Documents process to aid in:
– Accident investigation/analysis
– Accountability

7. 7
Regulatory Requirements
No current OSHA standard
OSHA provides guidelines on
Job Hazard Analysis
OSHA is likely to review your hazard
assessment program

13. 13
Prepare to conduct the JHA
1. Involve your employees.
2. Review your accident history.
3. Conduct a preliminary job review.
If any hazards exist that pose an immediate
danger to an employee’s life or health, take
immediate action to protect the worker.
4. List, rank, and set priorities for hazardous jobs.

14. 14
Involvement of Employees
They have a unique understanding of the
job, and this knowledge is invaluable for
finding hazards.
Involving employees will help minimize
oversights, ensure a quality analysis.
Get workers to “buy in” to the solutions
because they will share ownership

15. Hazard Awareness
When conducting a Job Safety Analysis you'll need to take a
fresh look at the way things are done at your work place.
Just because "We've been doing it this way for 20
years," doesn't mean that a hazard doesn't exist.
Accepting a risk or hazard is not the same as eliminating or
controlling it.
You'll need to take a comprehensive look at all possible
hazards with an open mind. (We'll suggest a way to rank the
hazards later.)

17. 17
Prioritization of JHA
Selecting a Job – consider the ff.
High frequency of accidents or near-misses
History of serious accidents or fatalities
Potential for serious harms
New jobs
Changes in procedures, standards, technology

18. Risk Assessment
Conduct a risk Analysis to help
prioritize jobs
R = P x S
Risk is a function of probability, and
severity
18

19. Risk Assessment
What is the probability?
• How likely will a worker be injured or become ill as a
result of an accident or exposure? (unlikely, likely,
very likely).
19

20. 20
Risk Assessment
Probability: the chance that worker will be
harmed
10 Very high Is the most likely and expected result if employee enters
danger zone.
6 High Is quite possible, would not be unusual, has an even 50/50
chance.
3 medium Would be unusual sequence or coincidence
1 low Would be remotely possible coincidence. It has been
known to have happened
0.5 Very low Extremely remote but possible. Has never happened after
many years of exposure.
0.1 Improbable Practically impossible sequence or coincidence. Has
never happened when exposed

21. What is the severity?
• How serious will the injury or illness be as a result of
an accident or exposure? (minor, serious, death).
21

22. 22
Risk Assessment
Severity: How serious will the injury or illness be
100 Catastrophe: Numerous fatalities
50 Serious Several fatalities;
30 High Fatality
20 Medium Extremely serious injury
10 Low Disabling injuries;
1 Minor Minor cuts, bruises, bumps; minor damage

23. 23
Risk Assessment
Factors that increase risk
exposure
• The proximity of employees to the
point of danger
• The number of employees exposed •
• The frequency and duration of
• Potential severity of the injury or illness•
• Working at elevation
• Unreasonable workload
• Working under stress (hurry, fatigue,
illness, personal problems)
• Any form of distraction that takes focus
away from the job
Lack of effective supervisor and
employee accountability, enforcement
• Lack of proper training of managers,
supervisor, employees
• Lack of adequate supervision
Improper or inadequate workplace
design

Breakdown the Job: Outline the Steps
• Watch the employee perform the job and list
each step as the worker takes it.
• Be sure to record enough information to
describe each job action without getting
overly detailed.
• Avoid making the breakdown of steps so
detailed that it becomes unnecessarily long or
so broad that it does not include basic steps.

31. 31
Breakdown the Job: Outline the Steps
• Review the job steps with the employee to
make sure you have not omitted something.
• Include the employee in all phases of the
analysis—from reviewing the job steps and
procedures to discussing uncontrolled hazards
and recommended solutions.

32. Breakdown the Job: Outline the Steps
Two of the most common errors made during
this stage:
• Describing the Job in too much details
• Describing the step in too detail.

Workshop 3: Identifying Basic Job
Steps
Task Description: As you leave from work today,
you discover that your car has a flat tire. The
car is parked on level ground, and the parking
is already set. The bumper jack and the spare
tire are both in good condition and stored in
the car’s trunk.
Direction: Breakdown and Identify the Basic Job
Steps

35. Identify & Describe the Hazards
35

36. Hazards
36
Is the potential to cause harm to a person or to
the natural environment
A condition or practice with the potential for
accidental loss.
– Substandard Condition (unsafe Condition)
– Substandard Acts (unsafe Acts)

37. 37
Identify the Hazards
• The physical actions required for that specific
steps
• The Materials used
• The Equipment used
• The Conditions under which the steps is
normally performed
• Physical Actions

38. 38
Identify & Describe the Hazards
• A job hazard analysis is an exercise in
detective work. Your goal is to discover the
following:
– What can go wrong?
– Where it is happening (environment)?
– What are the consequences?
– How could it arise?
– What are other contributing factors?
– How likely is it that the hazard will occur?

39. 39
Exposure
Exposure usually refers to an employee's placement
relative to the hazard’s “danger zone.” If the
employee is within the danger zone, the employee is
exposed. There are two general types of exposure:
When the person is generally
 Physical exposure.
within arm’s length.
 Environmental exposure. Due to e.g. noise,
hazardous atmospheres, temperature extremes.
Could be everyone in facility.

40. Identify & Describe the Hazards
Don't forget to look for
potential hazards

41. Don't forget to look for potential
hazards
To ensure
associated
that
with
all hazards
a step are
identified, analyze each step
to identify potential as well as
actual hazards produced by
both work environment and
the activity being performed.
Be sure to consider the
following:
41

42. 42
Be sure to consider the following:
 Is there danger of striking against, being struck by, or otherwise making
harmful contact with an object?
 Can the worker be caught in, by, or between objects?
 Is there potential for a slip or trip?
 Can the employee fall from one level to another or even on the same
level?
 Can pushing, pulling, lifting, lowering, bending, or twisting cause strain?
 Is the work environment hazardous to safety or health?
 Are there concentrations of toxic gas, vapor, fumes, or dust?
 Are there potential exposures to heat, cold, noise, or ionizing radiation?
 Are there flammable, explosive, or electrical hazards?

43. 46
Identify the Hazards: “ What If?”
Questions
• What if the team to
anticipate
Question allows
hazardous situations that might
occur if normal operating conditions were
suddenly changed or if a job step were to be
performed incorrectly or out of sequence.

44. 47
Common problems When Asking What
if?
Deciding when to stop considering possibilities
Solutions:
• Keep the discussion focused only on possibilities
that the team considers most likely
• Consults previous JHA and accident investigation
reports
• Talk with experienced operators

Workshop 4: Identify and Describe
Hazards
Task Description: As you leave from work today,
you discover that your car has a flat tire. The
car is parked on level ground, and the parking
is already set. The bumper jack and the spare
tire are both in good condition and stored in
the car’s trunk.
Direction: List all possible Hazards associated
to its basic steps you listed

47. Control Method Hierarchy
Proper remedial method order:
• Engineering controls
– Elimination
– Substitution
– Isolation
• Administrative controls
• Personal protective
equipment
Combinations of Controls
 Combinations of Controls may
need to be used if the hazard can't
be completely controlled by
engineering controls alone.
50

48. Engineering Controls
• Engineering controls include the following:
– Elimination/minimization of the hazard
– Substitution of equipment or process to
decrease hazard
– Isolation of the hazard with interlocks,
machine guards, blast shields, or other
means; and
– Removal or redirection of the hazard such
as with local and exhaust ventilation.
51

49. Administrative Controls
• Administrative controls include the
following:
– Written operating procedures, work
permits, and safe work practices;
– Exposure time limitations (used most
commonly to control heat stress and
ergonomic hazards);
– Monitoring the use of
hazardous materials;
– Alarms, signs, and warnings;
– Buddy system; and training
highly
52

50. PPE
• Personal Protective Equipment is acceptable
as a control method in the following
circumstances:
– When engineering controls are not feasible
or do not totally eliminate the hazard;
– While engineering controls are being
developed;
– When safe work practices do not provide
sufficient additional protection; and
– During emergencies when engineering
controls may not be feasible.

55. 58
Review JHA
Periodically reviewing your job hazard analysis
ensures that it remains current and continues
to help reduce workplace accidents and
injuries.
It is particularly important to review your job
hazard analysis if an illness or injury occurs on
a specific job.

56. 59
Review JHA
.
Any time you revise a job hazard analysis, it is
important to train all employees affected by
the changes in the new job methods,
procedures, or protective measures adopted.

57. Use the JHA
Don't just let the JHA collect dust!
60

58. Use the JHA
• as a lesson plan
– When training new employees
– Writing safe procedure,
• to dig up the roots
– When conducting incident/
accident investigation/ analysis
