RECALL AND CHECKRECALL AND CHECKMETHOD
Supervisor prepares a preliminary version based on his/her knowledge of the job.
Checks this by discussing with employee and observing parts of the job where there may be doubts.
Used for jobs where operator cannot be distracted or for urgent jobs that leave no time to arrange other methods of JHA.

HOWHOW TO DO A JHAHOW TO DO A JHA
1. Identify the job to be analysed.
2. Review the Hazard Register or existing JHA’s.
3. Break the job down into steps.
4. Identify the hazards and threats associated with each step and who or what
might be harmed.
5. Assess the potential of each hazard.
6. Develop solutions to eliminate or control the potential hazards.
7. Have you considered the effect of CHANGECHANGE in all the above?
8. Record the JHA.
9. Review the job on completion and update the JHA as necessary.

WHATWHAT IS “STEPBACK 5 x 5” ?WHAT IS “STEPBACK 5 x 5” ?
Stepback 5x5 is a process that encourages workers to identify hazards associated with ALL tasks before starting a job. It helps to promote a hazard management culture through continual self evaluation.
It is based on the principle of ‘ENGAGING THE MIND BEFORE THE HANDS’ by:
Stepping back 5 paces from the job
Investing 5 minutes (nominal) to step through the job in your mind and identify plans to control hazards before starting the job
Stepback 5x5 is an informal personal planning process. It is essentially a mental JHA applied before starting ALL jobs.
The process encourages sharing of information and experiences with others.

HOWHOW IS STEPBACK 5x5 DONE?HOW IS STEPBACK 5x5 DONE?
Before the job:
Stop and think
Observe the work area and surroundings
Step through your mind what you are going to do
Think about what else is happening in the area or nearby
Identify what else could go wrong
Satisfy yourself that the hazards are controlled before starting the work

HOWHOW IS STEPBACK 5x5 DONE?HOW IS STEPBACK 5x5 DONE?
After the job:
Observe the work area
Take action to control any hazards that may have been created by the work
Reflect on how well the job went and the mental planning process you used
Did you feel safe doing the job
Were others around you working safely
Can any improvements be made next time?
