A recent process hazard analysis audit at a large oil refinery where you work as a safety trainer reviewed process safety-related OSHA citations issued to a sister facility. The citations indicated that the other facility's process hazard analyses did not adequately address human factors for plant operations. You have been asked by facility leadership to prepare a PowerPoint presentation that gives an overview of human factors in the oil and gas industry to managers, engineers, and operators who are involved with performing process hazard analysis to ensure human factors are considered in future PHAs.

1. discuss human factors as they relate to oil and gas safety;
2. describe means for assessing human error;
3. discuss mechanisms for human decision-making;
4. discuss how safety culture, climate, and safety attitude influence human action
