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 5 PRE TASK ANALYSIS DATE: UNIT: COMPLETED BY: OTHER CREW MEMBERS: Pre Task - continued Pre Task Triggers - continued GENERAL q Discuss Job Hazards with Crew q Review Job Scope q Follow Procedure Use Policy q Necessary Procedure Available ELECTRICAL q Extension Cord Inspection q Work On / Near Energized Equipment q Procedure Required q GFCI Tested q Qualified q Voltage PRE TASK TRIGGERS OVERHEAD WORK q Barricades q Signage JOB DESCRIPTION: PTA MUST BE COMPLETED AT JOB SITE PRE TASK TOOLS q Correct Tools for Job q Tools Inspected Before Use PERMITS q Obtained Required Permits q Permit Receiver Confirmed Job Isolated q Meet all Permit Conditions q Signed into Block EMERGENCY q Know Location of Nearest PA / Telephone q Know Location of Nearest Safety Shower / Eyewash q Know Location of Nearest Assembly Point q Know Evacuation Route PPE q Available q Trained in Use S0165-06/02-PPT q Inspected / In Good Condition q Additional PPE Required ERGONOMICS q Awkward Body Position q Sustained Position q Twisting Motion q Reaction Forces ENVIRONMENTAL q Spill Potential q Waste Containers q Workers in Area q Flagging q Qualified to Use Tool q Tool Potential to Slip q Tool Potential to Fall q Over-Extension q Repetitive Motion q Pre Task Stretch HOUSEKEEPING q Aisle Ways Clear q Congestion GENERAL q Hot / Cold Surfaces q Pinch Points q Trip Potential q Sharp Objects q Rotating Equipment q Reactive Chemicals q Trash Containers q Containers Labeled q Procedure Available? q Slip Potential q Fall Potential q Tight Clearances q Industrial Hygiene Safety Suggestions RESULTING FROM THIS PTA q Waste Plan Required q Gasket Disposal LIFTING / PULLING / PUSHING q Manual Lift / Pull / Push (Excessive Force) q Assistance Required q Mechanical Lift (Crane, Chain Fall) q Condition of Equipment q Correct Rigging Practice 8 LIST TASK LIST HAZARDS How Can The Hazard Be Eliminated Or Controlled? E C STEPS MUST BE TAKEN TO IDENTIFY THE HAZARD AS EITHER ELIMINATED OR CONTROLLED PRIOR TO DOING THE TASK. 9 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 10 Task: Layout Pipe LIST HAZARDS FOUND FOR EACH TASK 1a. Pinch points to hands & feet from moving pipe 1b. Cuts from burrs on pipe 1c. Muscle strain from lifting pipe 2a. 2b. 2c. Section 2 Identifying Hazards Hazards Must Be Specific To The Tasks: -back strain from lifting 6” pipe -cuts from burrs on pipe -burns from hot welds 3a. 3b. 3c. MAKE SURE HAZARDS ARE DIRECTED TO YOU OR OTHERS 4a. 4b. 4c. 11 Task: Layout Pipe Section 3 Elimination & Control How Can The Hazard Be Eliminated Or Controlled? E C 1a. Use tag line when moving pipe a a 1a. Keep hands from between pipe & jack stand a 1b. Remove burrs before handling pipe a 1b. Wear leather gloves when handling pipe a 1c. Get help & use proper lifting techniques 1c. 2a. 2a. 2b. 2b. 2c. 2c. 3a. 3a. 3b. 3b. 3c. 3c. 4a. 4a. 4b. 4b. 4c. 4c. • 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? 12 Job Description: Fabricating Pipe LIST TASK 1.
