Job Safety / Hazard Analysis
Ohio BWC
  • Gary Peacock
  • Industrial Safety Consultant
  • 513-583-7081

2
COURSE OBJECTIVES
  • Introduce Job Hazard Analysis .
  • Introduce Some Basic Skills in the Recognition
    Control of Occupational Hazards.
  • Introduce Job Hazard Analysis Techniques.

3
Job Safety Analysis
  • What is it?
  • Process of studying and recording each step of a
    job, identifying existing or potential hazards,
    and determining the best way to perform the job
    to reduce or eliminate the hazards.

4
JSA
  • JSA is used to determine
  • Physical, procedural, and/or environmental based
    hazards that do or could exist
  • Actions of personnel which could result in
    accidents or injuries
  • Measures to be implemented which will eliminate
    or control hazards so the job can be performed
    safely

5
Elements of JSA
  • Four basic steps
  • Selecting jobs for analysis
  • Breaking each selected job into steps
  • Identify the hazards associated with each step
  • Eliminate or correct the hazards

6
JSA Benefits
  • Prevention/reduction of hazards in the
    performance of your job
  • Prevention/reduction of occurrences of accidents
  • Improvements in job performance
  • Coordinates with PPE selection, Ergonomic
    assessments, complying with ADA
  • Standardizes work procedures

7
More Benefits
  • Employee training
  • Identify jobs for return to work program
  • Employee orientation
  • Job reviews
  • Document corrections and improvements
  • Safety Audits
  • Accident Investigations

8
OSHA Requirements
  • General Duty Clause 5(a)(1)
  • Many OSHA Standards require hazard analysis
  • EAP
  • Hazcom
  • PPE
  • LOTO

9
When Should JSA Be Created
  • JSA should be performed when
  • Job does not currently have JSA
  • New job is created
  • When accident or near miss occurs
  • When employee has concern

10
Members of JSA Team
  • No single method
  • Typical members
  • Safety manager
  • Safety team members
  • Employees
  • Supervisors
  • Human Resources
  • Engineering

11
Employee Involvement
  • Reasons for involving employees
  • Familiarity
  • Identify hazards not observable
  • Avoids alienation
  • Gains buy-in for necessary changes

12
Employee Involvement
  • Discuss process with employees performing the job
    and explain purpose
  • Involve employee in all phases after job
    selection
  • Higher success rates
  • More effective JSA results

13
Resistance
  • Departmental managers may not fully cooperate
    because
  • Process seen as a disruption to their work area
  • Employee involvement detrimental to productivity
  • Overcome by communicating benefits of JSA and
    involving management members in the process

14
Approaches to JSA
  • Observation Method
  • Discussion Method

15
Observation Method
  • Directly observe the job task, to evaluate each
    step and understand the hazards involved.
  • Ask questions of the operators and draw upon
    their knowledge of established procedures,
    problems, and difficult areas
  • Preferred Method

16
Discussion Method
  • Requires getting people together who have
    knowledge of the job and discuss a particular job
    task.
  • Job analysis is not done at the site of the job.
    Some points could be missed.
  • Secondary Method

What is a Job?
19
What is a Job?
  • A JOB is a description of a function in the
    company
  • Supervisor Assembler Material Handler
  • Each job is made up of TASKS.

20
Examples of Tasks
  • TASK sequence of steps or activities that
    together accomplish a goal.
  • Hanging a door
  • Unloading drums from truck with forklift
  • Filling cans on an assembly line
  • Machining parts in a mill

21
Step 1 Selecting Jobs for JSA
  • High risk jobs first
  • Indicators used to select jobs
  • Frequency
  • Severity
  • Potential Severity

22
Materials to Aid in Job Selection
  • Accident reports
  • OSHA logs
  • Workers Compensation claims

23
Step 2 Job Task Breakdown
  • List each step of the job in order of occurrence
    as you watch the employee perform the job.
  • Dont break the job down into steps so small as
    to be meaningless or too broad that something is
    missed.

24
Tools and equipment
  • Video camera
  • Digital Camera
  • Tape recorder
  • Notebook
  • Employee Interview
  • Supervisor Interview

Planting A Tree (example 1)
  • Dig hole.
  • Insert tree.
  • Backfill planting.
  • Whats wrong with this?

27
Planting A Tree (example 2)
  • Pick up shovel
  • Position shovel
  • Put foot on shovel
  • Push shovel with foot.
  • Etc.
  • Whats wrong with this?

28
Planting A Tree (example 3)
  1. Bring tools
  2. Dig hole
  3. Prepare hole
  4. Position tree in hole
  5. Backfill, tamp, and water
  6. Brace tree
  7. Return tools

29
Rule of Thumb
  • Most jobs will separate into 10-15 basic steps,
    although some will have fewer and some may have
    more.

30
Employee Interviews
  • Conduct interview near work area
  • Explain only looking for facts
  • Ask open ended questions
  • Ask employee to write down job steps
  • Thank person for helping

31
Information Review
  • Using information gathered, including employee
    interview, review and revise job steps as
    necessary to accurately reflect current
    performance of job.

32
Step 3 Identifying Hazards
  • Recorded steps must be examined to determine
    hazards that exist or might occur.
  • Identification of hazards should include the
    hazards associated with machines, tools,
    supplies, job procedures, and the surroundings

33
(No Transcript)
34
Hazard Types
  1. Contact by or against objects.
  2. Caught in or between objects
  3. Falls same level.
  4. Falls elevation.
  5. Overexertion.
  6. Environmental exposure

35
Additional Training
  • Do JSA Team Members need additional training in
    hazard recognition?
  • Know difference between physical and health
    hazards?
  • Understand basic electrical principles?
  • Understand hazards of extreme hot or cold
    environments?

36
Step 4 Controls
  • After hazards or potential hazards have been
    listed and reviewed, the next step is
  • eliminate the hazards, or
  • reduce the hazards.

37
(No Transcript)
38
Controls
  • Substitution
  • Job Redesign
  • Engineering Revisions
  • Procedural Revisions
  • Personal Protective Equipment
  • Training
  • Administration Controls

39
Hierarchy of Hazard Correction
  • Use Engineering controls where feasible and
    appropriate
  • Use Administrative controls, such as reducing the
    duration of exposure.

40
Hierarchy of Hazard Correction
  • Use Procedures for safe work which are understood
    and followed by all parties, as a result of
  • training,
  • positive reinforcement,
  • correction of unsafe performance, and
  • enforcement through a clearly communicated
    disciplinary system
  • Use Personal Protective Equipment

41
Reviewing/Revising JSAs
  • JSA are only effective if they are reviewed and
    updated periodically.
  • Trigger points
  • When accidents occur
  • When the job process changes
  • After near misses
  • Employee complaint
  • Equipment suffers damage
  • Periodic Reviews

42
Conclusion
  • The process of JSA can be applied to any job in
    any workplace, to improve work procedures and
    make jobs safer and easier to perform.
  • The goal of this process is to educate everyone
    by getting them involved in identifying hazards
    and developing controls to keep everyone safe.

43

WORKSITE ANALYSIS
  • WORKSITE ANALYSIS IS DIVIDED INTO FOUR MAIN
    PARTS

1. Gathering information from available
sources. 2. Conducting baseline screening
surveys to determine which jobs need a closer
analysis. 3. Performing job hazard analyses of
those work stations with identified risk
factors. 4. After implementing control
measures, conducting periodic surveys and
follow-up to evaluate changes.

JOB SAFETY ANALYSISSummary
96
Job Safety Analysis
  • The breaking down into its component parts of any
    method or procedure to determine the hazards
    connected with each key step and the requirements
    for performing it safely.

97
Job Safety Analysis Priorities
  • New Jobs
  • Severity Potential
  • History of Disabling Injuries
  • Frequency of Accidents

98
Job Safety Analysis
  • Job means task
  • (Changing a tire not auto mechanic)
  • key steps
  • too detailed becomes cumbersome
  • not enough detail becomes useless

99
Break job down into key steps
AVOID
  • making the breakdown so detailed That an
    unnecessarily large number of steps results
  • making the job breakdown so general that basic
    steps are not recorded

100
Group Activity
  • Job Safety Analysis
  • Changing a Flat Tire on an Automobile

101
Key Steps (TOO MANY)Changing a Flat Tire
  • Pull off road
  • Put car in park
  • Set brake
  • Activate emergency flashers
  • Open door
  • Get out of car
  • Walk to trunk
  • Put key in lock
  • Open trunk
  • Remove jack
  • Remove Spare tire

102
Key Steps (NOT ENOUGH)Changing a Flat Tire
  • Park car
  • take off flat tire
  • put on spare tire
  • drive away

103
Key Job Steps JUST RIGHTChanging a Flat tire
  • Park car, set brake
  • remove jack tire from trunk
  • loosen lug nuts
  • jack up car
  • remove tire
  • set new tire
  • jack down car
  • tighten lug nuts
  • store tire jack

104
Hazards
  • Parking Car
  • Struck by Traffic
  • Removing tire jack
  • Back Strain
  • bang head on trunk
  • Loosen lug nuts
  • back/arm strain
  • slip fall
  • Jacking up car
  • car could fall off jack
  • Setting new tire
  • fingers pinched
  • back strain
  • Tighten nuts
  • back strain
  • slip fall

105
Work Observation
  • Select experienced worker(s) who will cooperate
    and participate in the JSA process.
  • Explain purpose of JSA.
  • Observe the employee performing the job and write
    down basic steps.
  • Completely describe each step.
  • Note deviations (Very Important!)

106
Identify Hazards and Potential Accidents
  • Search for Hazards
  • Produced by Work
  • Produced by Environment
  • Repeat job observation as many times as necessary
    to identify all hazards

107
Develop Solutions
  • Find a new way to do job
  • Change physical conditions that create hazards
  • Change the work procedure
  • Reduce frequency

108
New way to do job
  • Determine the work goal of the job, and then
    analyze the various ways of reaching this goal to
    see which way is safest.
  • Consider work saving tools and equipment.

109
Change in physical conditions
  • Tools, materials, equipment layout or location
  • Study change carefully for other benefits (costs,
    time savings)

110
Change in work procedures
  • What should the worker do to eliminate the
    hazard
  • How should it be done?
  • Document changes in detail

111
Reduce frequency
  • What can be done to reduce the frequency of the
    job??
  • Identify parts that cause frequent repairs -
    change
  • Reduce vibration save machine parts

112
What effects??
  • A job that has been redesigned may affect other
    jobs or work processes.
  • Check or re-observe the new process once it has
    been redesigned
