Describing the Hazard Scenarios
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?
Major Hazards (examples)
Hazard Controls
 Chemical (Toxic)
Engineering:
 Chemical (Flammable
 Eliminate/minimize or remove the
 Chemical (Corrosive)
hazard
 Chemical (Reaction)
 Enclosure of the hazard
 Explosion
 Isolation of the hazards (guards,
 Electrical (Shock/ Short
shields etc.)
Circuit)
 Removal or redirection of the hazard
Where is it happening (environment)?
Who or what it is happening to (exposure)?
What precipitates the hazard (trigger)?
What would the outcome be should it happen (consequence)?
Any other contributing factors (time of day, weather,)
JSA Category Descriptions
Sequence of Job Steps: Break the job down into steps. Each of the steps of a job should accomplish some
major task. The task will consist of a set of movements. Look at the first set of movements used to perform
a task, and then determine the next logical set of movements. For example the job might be to move a box
from a conveyor in the receiving area to a shelf in the storage area. How does that break down into job
steps? Picking up thebox from the conveyor and putting it on a hand-truck is one logical set of movements,
so it is one job step. Everything related to that one logical set of movements is part of that job step. Be sure
to list all the steps in a job. Some steps might not be done each time but, that task is a part of the job as a
whole and should be listed and analyzed.

Potential Hazards: Identify the hazards associated with each step. Examine each step to findand identify
hazardous actions, conditions and possibilities that could lead to an accident.
It's also important to look at the entire environment and discover every conceivable hazard that might
exist. Be sure to list health hazards as well even though the harmful effect may not be immediate. It's
important to distinguish between a hazard, an accident, and an injury. Each of these terms has a specific
meaning: HAZARD-A potential danger. Oil on the floor is a hazard. ACCIDENT-An unintended happening
that may result in injury, loss, or damage. Slipping on the oil is an accident. INJURY-The result of an
accident. A sprained wristfrom the fall would be an injury. Some people find it easier to identify possible
accidents and illnesses and work back from them to the hazards. If you do that, you can list the accident
and illness types in parentheses following the hazard. But be sure you focus on the
hazard for developing recommended actions and safe work procedures.
Personal Protective Equipment
Recommended Action or Procedure: Using ·the first two columns as a guide. Decide what actions are
necessary to eliminate or minimize the hazards that could lead to an accident, injury, or occupational
illness. Among the actions that can be taken are: 1) engineering the hazard out; 2) providing personal
protective equipment; 3) job instruction training; 4) goodhousekeeping; and 5) good ergonomics. List
recommended safe operating procedures on the form, and also list required or recommended personal
protective equipment for each step of the job. Be specific.
