Job Safety Analysis(JSA)


What is job and task
·         The terms "job" and "task" are commonly used interchangeably to mean a specific work assignment.
 such as
"operating a grinder,"
"using a pressurized water extinguisher,“
 or           "changing a flat tire."
What is a job safety analysis?
v        A job safety analysis (jsa) is a procedure which helps integrate accepted safety and health principles and practices into a particular task or job operation.
v        In a jsa, each basic step of the job is to identify potential hazards and to recommend the safest way to do the job.
v        Other terms used to describe this procedure are job hazard analysis (jha) and job hazard breakdown.
What are the benefits of doing a job safety analysis?
v        One of the methods used in this example is to observe a worker actually perform the job.
v        The major advantages of this method include that it does not rely on individual memory and that the process prompts recognition of hazards.
v        For infrequently performed or new jobs, observation may not be practical.
What are the four basic steps?
Four basic stages in conducting a jsa are:
v        Selecting the job to be analyzed
v        Breaking the job down into a sequence of steps
v        Identifying potential hazards
v        Determining preventive measures to overcome these hazards
What is important to know when "selecting the job"?
                ideally, all jobs should be subjected to a jsa. Even if analysis of all jobs is planned, this step ensures that the most critical jobs are examined first.
v        Factors to be considered in setting a priority for analysis of jobs include:
v        Accident frequency and severity:
v        Potential for severe injuries or illnesses:
v        Newly established jobs:
v        Modified jobs:
v        Infrequently performed jobs:
How do i break the job into "basic steps"?
v        Care must be taken not to make the steps too general. Missing specific steps and their associated hazards will not help. On the other hand, if they are too detailed, there will be too many steps. A rule of thumb is that most jobs can be described in less than ten steps. If more steps are required, you might want to divide the job into two segments, each with its separate jsa, or combine steps where appropriate.
How do i "identify potential hazards"?
v        To help identify potential hazards, the job analyst may use questions such as these ( this is not a complete list):
v        Can any body part get caught in or between objects?
v        Do tools, machines, or equipment present any hazards?
v        Can the worker make harmful contact with moving objects?
v        Can the worker slip, trip, or fall?
v        Can the worker suffer strain from lifting, pushing, or pulling?
v        Is the worker exposed to extreme heat or cold?
v        Is excessive noise or vibration a problem?
v        Is there a danger from falling objects?
v        Is lighting a problem?
v        Can weather conditions affect safety?
v        Is harmful radiation a possibility?
v        Can contact be made with hot, toxic, or caustic substances?
v        Are there dusts, fumes, mists, or vapours in the air?
How do i "determine preventive measures?"
v        The final stage in a jsa is to determine ways to eliminate or control the hazards identified. The generally accepted measures, in order of preference, are:
v        1. Eliminate the hazard: use a machine guard
v        2. Contain the hazard
v        3. Revise work procedures
v        4. Reduce the exposure
