Four basic stages in conducting a JSA are:

• selecting the job to be analyzed
• breaking the job down into a sequence of steps
• identifying potential hazards
• determining preventive measures to overcome these hazards

Questions to Consider:
What can go wrong?
What are the consequences?
How could it arise?
What are the other contributing factors?
How likely is it that the hazard will occur?
Where is it happening?
Who will be exposed?
What consequences may happen?
Any other contributing factors?
Specific questions:
Can any body part get caught in or between objects?
Do tools, machines, or equipment present any hazards?
Can somebody make harmful contact with moving objects?
Can somebody slip, trip, or fall?
Can somebody suffer strain from lifting, pushing, or pulling?
Can somebody exposed to extreme heat or cold?
Is excessive noise or vibration a problem?
Is there a danger from falling objects?
Is lighting a problem?
Can weather conditions affect safety?
Is harmful radiation a possibility?
Can contact be made with hot, toxic, or caustic substances?
Are there dusts, fumes, mists, or vapors in the air?


Eliminate the hazard
• Choose a different process
• Modify an existing process
• Substitute with less hazardous substance
• Improve environment (ventilation)
• Modify or change equipment or tools
• If the hazard cannot be eliminated, contact might be prevented by using enclosures, machine guards, worker booths or similar devices.
Revise Work Procedures
• Consideration might be given to modifying steps which are hazardous, changing the sequence of steps, or adding additional steps (such as locking out energy sources). Reduce the Exposure
• These measures are the least effective and should only be used if no other solutions are possible.
• One way of minimizing exposure is to reduce the number of times the hazard is encountered.
• The use of appropriate personal protective equipment may be required.
