Why Must Ways to Eliminate or Control Hazards Be Developed?
There are ways to eliminate the hazards by choosing a different process, modifying an existing process, substituting with a less hazardous substance, or improving the environment. In developing solutions, the following steps can be taken:
- • Find a new way to do the job.
- • Change the physical conditions that create the hazard.
- • Change the procedure to eliminate the hazard.
- • Reduce the frequency of job performance. Reduce exposure.
- • Contain the hazard with an enclosure, a barrier, or guards.
- • Use protective devices such as PPE.
Why Change Job Procedures?
If the sequence of job steps or the deviations from established job steps are critical to the safe performance of a job, this should be noted in the JSA/JHA. The next part of the JSA process is to develop the recommended safe job procedures to eliminate or reduce potential accidents or hazards that have been identified. The following four points should also be considered for each hazard identified for the job step:
- 1. Can a less hazardous way to do the job be found?
- 2. Can an engineering revision take place to make the job or work area safer?
- 3. Is there a better way to do the job? This requires determining the work goal and then analyzing various ways to reach the goal to see which way is safest.
- 4. Are there work-saving tools and equipment available that can make the job safer?
What to consider with this group of questions is how the equipment and work area can be changed, or provided with additional tools or equipment, to make the job safer.
