E N D
What’s the difference? • Job Safety Analysis • Job Hazard Analysis
What is Job Safety Analysis ? • An analysis of the potential hazards associated with a specified job task. • Definition of a Job Task: • A job task is NOT a position or occupational title. • A job task IS a sequence of specific work steps that together accomplish a work goal.
Definition ... • Is “Auto Mechanic” a job task? • No, it is a job title • Examples of “Auto Mechanic” job tasks: • Changing a flat tire • Installing an alternator • Charging a battery
What is a JSA / JHA? • A systematic analysis of each step of a job task with the intention of identifying each potential hazard of the job step and control of those hazards
The JSA / JHA program • Procedures for initial JSA evaluations • Procedures for maintaining the JSA’s • Procedures for adding new JSA’s • Procedures for the periodic review and/or up-dating of JSA’s • Procedures for using the JSA’s
What good is a JSA / JHA? • A means of identifying and recording hazards in the workplace • New employee orientation • Safety meeting topics • Pre-job safety training • Review before infrequently performed job tasks (hazards, procedures, PPE, etc.) • Re-familiarize oneself with the known hazards of a specific job task • Job descriptions, early return to work • Planned safety contacts and/or observations
Three - step approach • Break the job task down into an orderly sequence of steps • Identify and record the hazards and potential sources of accidents • Develop a solution, control or procedure to nullify each hazard identified
Key points • Not all jobs have an equal number of hazards • Some hazards are more hazardous than others - FREQUENCY • Some hazards create a greater potential for loss than others - SEVERITY • For every known hazard associated with a job step, there is a solution to nullify the hazard
Key points • JSA’s take time • JSA’s must be kept current
How to do a JSA / JHA? 1. Select the person(s) to do the analysis 2. Select the Job Task to be analyzed 3. Select the employee(s) to be observed 4. Inform the employee(s) of the purpose of the observation 5. For repetitive job tasks, observe several repetitions
How to do a JSA / JHA? 6. Identify each job step necessary to accomplish the job task 7. Identify each potential hazard/accident source associated with the job task 8. Review with the employee • The steps involved in the job task • The hazards identified with each job step 9. Develop procedures for each identified hazard
Who should prepare JSA’s? • Supervisors/foremen • Skilled employees experienced in the job task • Other personnel trained in performing JSA’s
Select the job task • Identify hazardous job tasks • Accident frequency / severity • Known potential for severity • Newly established job tasks • Job tasks that have been redefined or changed • Check against the opinion of others • Let future accidents add job tasks to your list
Selecting the employee for observation • Get the best available worker you can • Observe more than one worker, if possible • Select a worker who is willing to share knowledge and experience
Observing the job task • Position yourself where you can see clearly without getting in the worker’s way • Don’t interrupt the workflow • You may have to observe the job task several times to ensure you have recorded the necessary steps in their proper order
Identifying job steps • A job step should be a sequential action or group of related actions needed to accomplish a portion of the job task • Each job step should have a specific beginning and end • Job steps should not be too detailed or too simple
1. Position car, set brakes, block wheel 2. Remove spare tire, position 3. Position car jack 4. Jack up car 5. Remove hub cap 6. Remove wheel bolts 7. Remove flat tire 8. Position spare tire 9. Tighten wheel bolts 10. Replace hub cap 11. Jack car down, remove block 12. Store jack and flat tire Identifying job steps:Changing a tire
Too Much Detail Park the car Get out of the car Walk to the car trunk Open the car trunk Insufficient Detail Remove the flat tire Put on the replacement tire Errors to avoid
Housekeeping/walking/ working surfaces Chemical contact Tools/machinery Moving/falling parts In-running nip points Sharp objects/edges Noise/dusts/vapors Manual handling Excessive force Temperature extremes Body positioning Fall potential What do you observe for?
Ask yourself (Unsafe conditions) • Can employee be struck by or contacted by anything? • Can employee strike against or make injurious contact with anything? • Can employee be trapped in, caught on, or caught between anything? • Can employee slip or trip on anything? • Is the employee subject to any environmental hazard exposure, i.e. dust, gas, fumes, radiation, heat, noise? • Can employee injure a fellow employee?
Improper material handling procedures Improper use of PPE Rushing/running Disregard of company safety rules Unsafe operation of lift trucks Standing/climbing on chairs, machinery, etc. Disregard of machine operating procedures Removing/defeating machine guards Clearing jams while machinery is moving Repair/service of machinery without Lock-out Ask yourself (Unsafe acts)
Check your understanding • Review your breakdown of the job steps with the observed employee(s) • Review your assessment of job hazards with the observed employee(s) • Enlist their support in the development of proper procedures, safety controls &/or PPE
Preparing the JSA form • Complete the headings at the top • Assign a JSA Number • Record the Plant, Department, Area • Identify the Job Task • Give a brief description of the job task
Preparing the JSA form • Complete the body of the analysis by using the four columns: • Enter the Job Step number • Give basic description of the job step • Identify each potential hazard associated with the job step • Recommend one or more actions or procedures for each identified hazard
Recommended actions • Safe operating procedures • Special tools needed for the job step • PPE required • Special warnings or cautions • Based upon the analysis, modifications in machinery, layout, materials, frequency of job task, etc., may be in order
The bottom line • By identifying all potential hazards, to: • Eliminate the hazard altogether • Isolate the hazard • Protect against the hazard • Reduce the potential for occurrence • Reduce the frequency and/or severity of the hazard
