JSA
1. INTRODUCTION
Job Safety Analysis (JSA) is a simple structure approach used to assess potential hazards associated with any identified activity and to ensure risks are minimized. JSA applies the standard Hazard Management Process (HMP) of:
• Identify the potential hazards and Evaluate the Risks；
• Establish controls (to avoid hazards)；
• Plan recovery measures (if things do go wrong)；
This can be applied to any task。
2. Approach
For larger or more complex tasks, the initial JSA can be carried out as a desktop exercise at the office. However, a key principle is that the proper JSA is done in the field with people experienced in the activities and with the facilities.
The following steps are taken:
Person from group undertaking the task undertakes preparation for the JSA. Breaks the activity into the key steps and records this on the Job Safety Analysis Worksheet (refer to the following worksheet)；
Assemble JSA team (3 or 4 personnel). Need mix of skills. Recommend: one operational person who knows the area and the process facility, one from the group undertaking the task and a safety professional；
Each step reviewed for what could go wrong and list the credible hazards. To help this the team can use the hazards checklist developed by professionals for the specific tasks；
For each hazard the present specified control measures should be identified and assessed for effectiveness；
For each hazard the need for further controls should be considered by asking the question “what more could we do to reduce the risk from this identified hazard?” Sensible additional controls are then added to the worksheet；
Following completion of the review the safety supervisor /coordinator /manager should summarize the special controls identified by the team for that activity on the Job Safety Analysis Worksheet. This will list the activity hazards, the special control requirements and who has to implement the controls during the task execution；
The safety Supervisor/Coordinator/Manager files the JSA and may add it to the Asset JSA database if it is considered that the activity may be repeated；
The task supervisor has to ensure that the JSA worksheet is included along with the Work Request Form when the Permit to Work is being initiated；
The Task supervisor is responsible for a brief to the work party on the job hazards, controls and limitations (pre-job safety meeting) and ensures all controls are implemented as required in JSA worksheet；
