Job safety analysis
Job safety analysis evolved from a job or task analysis and is defined as: ‘The identification of all the accident prevention measures appropriate to a particular job or area of work activity and the behavioral factors which most significantly influence whether or not these measures are font-size: 12pt;"
Job/task analysis
The identification and specification of the skill and knowledge contents of jobs.
Job/task training analysis
The identification and specification of what has to be taught and learned for individual jobs.
Job safety analysis
The approach is both diagnostic and descriptive. It may be job-based or activity-based.
- Job-based: Machinery operators; forklift truck drivers
- Activity-based: Manual handling operations; roof work; cleaning activities.
Job safety analysis evolved from:
- a) task analysis; and
- b) method study and work measurement (SREDIM).
The latter incorporates the SREDIM principle, namely:
SELECT – the work to be studied
RECORD – the method of doing the work
EXAMINE – the total operating system
DEVELOP – the optimum methods for doing the work
INSTALL – the method into the company’s operations
MAINTAIN – the defined and measured method
Applying the SREDIM principle to job safety analysis, the procedure is as follows:
- Select the job to be analyzed.
- Break the job down into component parts in an orderly and
chronological sequence job.
- Critically observe and examine each component part of the job to determine the risk of an accident.
- Develop control measures to eliminate or reduce the risk of an accident.
- Formulate written safe systems of work and job safety instructions.
- Review safe systems of work and job safe practices at regular intervals to ensure utilization.
Job safety instructions
These are used as a means of communicating the safe system of work to the operator. They can be produced as:
- a) a general manual covering all jobs;
- b) specific cards attached to machines or displayed in the work area.
Criteria for selection of jobs for analysis
- Past accident and loss experience
- Maximum potential loss
- Probability of accident recurrences
- Legal requirements
- Relative newness of the job
- Number of employees at risk
A Job Safety Analysis record should be maintained for each job analyzed.
Stages of job safety analysis
Job safety analysis usually takes place in two specific stages, each of
Which has different information requirements?
Initial job safety analysis
The following factors are considered:
Job title Department/Section
Job operations Machinery/equipment used
Materials used Protection needed
Hazards Degree of risk
Work organization Specific tasks
Total job safety analysis
The following factors are considered:
Operations Hazards
Skills required External influences on behavior
Learning methods
