Balanced System
Balance, based on the risk and complexity of the task.

Each side of the triangle can impact job performance. All need to be evaluated during the job planning
process.
Procedure appropriate to the task and worker
Knowledge, skill, and ability of the worker considered when developing the
procedure controls
4
Worker Involvement
• Workers are the key in identifying hazards and controls of tasks
• The workforce is being trained in use of error precursors and error likely situations
• Worker experience and training is considered in process and procedure development
• The worker knows when to stop and re-evaluate conditions and situations
• Greater worker involvement minimizes need for programmatic reviews in job planning and execution
5
Critical Task
• Certain tasks are more critical than others Some actions/tasks are irrecoverable; once the action is
taken, the reverse action cannot recover
• Some steps have more chances for error • Need to consider critical tasks as part of hazards
analysis Is changing the state of the facility, system, component, or
the well-being of the individual dependent on the individual worker?
Is the outcome of the error intolerable from a personnel safety or facility perspective?
• Helps focus attention on potential consequences so appropriate defenses can be put in place

Work Site Hazard Analysis
2 page site form: Standards set by ES&H and used by the Workers and Supervisors
Used at the BeginningDuring the Planning
And at the Jobsite

Performing Work
Perform the work
Walkdown Work site
Post Job Briefing
Lessons Learned
Feedback
Verify conditions are as expected and that Instructions can be worked to as written
Perform work to instructions or as Skill based
Document the work
Pre-job Briefing
Communicate the scope , hazards, and controls

HPI Impacts in Hazard AnalysisBefore
• 4 Major tasks• 26 Sub-tasks• 41 Hazards (most slips trips falls)
• 152 Controls (most skill-of-craft)
• No error precursors• Missed critical task
After• 4 Major tasks• 26 sub-tasks• 1 Hazard for Critical task• 6 Controls• Error precursors identified• Controls focused on critical task
18
HPI Impact on Work InstructionsBefore
• 17 Precautions• 15 Prerequisites• 8 Notes• 4 Cautions• 2 Hold Points• 63 steps for skill-of-the-craft• 47 steps for unidentified “critical task” buried in extraneous information
After• 5 Precautions• 4 Prerequisites• 0 Notes• 2 Warnings (Hazard for critical task)• 2 Hold Points• 11 steps to augment skill-of-the-craft• 42 steps for “critical task”
19
HPI Impact on Work and JHA Processes
Before• 8 categories of work• 3 pgs of a matrix to categorize work• 89 pages in work control• 11 attachments
After• 3 Categories of work• 3 definitions• 38 pages in work control procedure • 4 attachments
Work Control Procedure
Job Hazard Analysis ProcedureBefore
• Procedure focus on administration• Had to be on computer to use • 19 pages in on administration• No hazards discussed in procedure
After• Procedure focus on hazard mitigation• 2 page form used in the field• 6 pages on process • General hazards covered in procedure• Critical Tasks and Error Precursors
20
Pre-Job Briefings
• Incorporated HPI concepts into Pre-job briefing Process
• Simplified the process
• Procedure went from 12 pages to 8
• Pre-job Checklist modified to focus on topics identified in INPO HPI tools document
• Removed redundant requirements
• Shortened the checklist to make more user friendly
21
EFCOG Assist VisitJuly 2006
• Multi-site review coordinated by EFCOG Work Management Subgroup
• 1st of its kind review• Used work management CRADs• Evaluated implementation of HPI in work
management• Conclusions
Critical task application viewed as a strength Worksite hazards analysis viewed as strength Continue mentoring and managing process
22
Lessons Learned
• Use of HPI concepts resulted in improved work planning
• Error precursors and proactive event prevention concepts were successfully applied to work planning
• Improved focus on hazards with consequences • Removed skill-of-the craft controls reduced level
of package detail • Critical hazard controls more clearly evident
From static to dynamic Hazards Analysis
• Worker attention focused on hazard controls
