Using HPI Tools in Tank Farm Work Control and Hazard Analysis Process

2. 2 HPI & Work Control Performance GAPs Critical Tasks Developing Work Instruction Controls Job Hazards Analysis Job Safety Plan Work Instruction Conclusions & Benefits

3. 3 Performance GAPs in Work Control Use of the Critical Task concept Proactive planning using error precursors Tailoring controls to the critical task Ensuring controls are not buried in extraneous information Ensuring workers attention is properly focused

4. 4 Critical Task Not all aspects of a job are equally important 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 as part of hazards analysis Is changing the state of the facility, system, or component or 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
