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.

job safety analysis priorities
Job Safety Analysis Priorities
  • New Jobs
  • Severity Potential
  • History of Disabling Injuries
  • Frequency of Accidents

Job Safety Analysis
  • Job means “task”
  • (Changing a tire not auto mechanic)
  • “key” steps
  • too detailed becomes cumbersome
  • not enough detail becomes useless
break job down into key steps
Break job down into key steps
  • 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

Job Safety Analysis

“Changing a Flat Tire on an Automobile”

key steps too many changing a flat tire
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
key steps not enough changing a flat tire
Key Steps (NOT ENOUGH)Changing a Flat Tire
  • Park car
  • take off flat tire
  • put on spare tire
  • drive away
key job steps just right changing 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

Key Job Steps JUST RIGHTChanging a Flat tire
hazards

Struck by Traffic

Removing tire & jack

Back Strain

bang head on trunk

back/arm strain

slip & fall

Jacking up car

car could fall off jack

Hazards
work observation
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!)
identify hazards and potential accidents
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
develop solutions
Develop Solutions
  • Find a new way to do job
  • Change physical conditions that create hazards
  • Change the work procedure
  • Reduce frequency
new way to do job
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.
change in physical conditions
Change in physical conditions
  • Tools, materials, equipment layout or location
  • Study change carefully for other benefits (costs, time savings)
change in work procedures
Change in work procedures
  • What should the worker do to eliminate the hazard
  • How should it be done?
  • Document changes in detail
reduce frequency
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
what effects
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
