Pre-Task Analysis
What is Pre-task analysis?
•Thinking about the steps of a job BEFORE doing the job
•Thinking about the hazards of each step
•Thinking about ways to eliminate or control the hazards
PTA IS PLANNING!
PLANNING IS PAYING ATTENTION TO DETAIL!
1
Pre-Task Analysis vs. Work Permits
• A typical work permit fully covers hazards from a
“prepare” perspective and only partially from a “do”
perspective.
• However, there is a gap that is not covered by the work
permit. Hazards resulting from the specific execution of the
job/task (e.g. body position, manual lifting, pinch point
resulting from equipment dismantling, etc.) are not always
considered or foreseen in the work permit.
• The PTA is intended to fill in this specific gap and
therefore should be considered as an extension of the
hazard analysis that the work permit in itself partially
provides.
3
Trigger Criteria
• Triggers that should prompt use of PTA.
• it is advisable to always have a PTA card with you. This will ensure
that when you need a card it is always readily available
• when signing onto a permit as an approver, operator or tradesman
• when the work environment changes (e.g. snow, ice, heat)
• routine job/tasks that has been subject to change
• non-routine job/task
• Job/task that is not covered by a procedure
4
Identifying Potential Hazards
• Use potential hazard list on the front of the PTA card as a
prompt.
• The hazards listed on the front of the PTA cards are not all
inclusive. They are also intended to be triggers for the thought
process.
• The identified hazards must be written on the free text section
of the PTA card.
• Make sure the entire crew “understands” the hazards and
hazard elimination/controls

LIST TASK
1. Layout pipe
Section 1 - Task Analysis
Why do we do task analysis?
Task analysis is conducted to look at the job
in small parts, to identify hazards, and
eliminate and control the hazards.
2. Cut/weld pipe
Task Analysis
Analyze the job tasks - 3 to 5
• Break job down to at least three tasks to be
sure you are not analyzing too much of the
job at a time.
3. Grind pipe
• There should be no more than five tasks,
this is not a job procedure.
4.
• Group similar tasks to eliminate repeat of
hazards: example - Loosen lugs/tighten lugs
Remove/replace pump

• Elimination is the removal of the hazards
from the work area
• Control is the reduction of the risk
associated with the hazard (PPE, etc.)
You must identify an elimination or a control for
every specific hazard that was identified.
You must be specific in the controls that are
identified.
NOTE: PPE is always a control.
— leather gloves — ear plugs
— monogoggles — rubber boots
Have to ask the question of every hazard:
— How can I eliminate the hazards?
