Frequently Asked Questions
What is a PSIF in safety?
PSIF stands for serious injury and fatality potential. It refers to incidents, near misses, or unsafe conditions that had a credible pathway to a life-altering or fatal outcome, even if the actual outcome was minor.
Why can a minor incident still have PSIF potential?
A first-aid case or near miss can still show a failure with fatal potential if high-risk exposure was present. The post explains that teams should ask how bad the event could reasonably have been, not just how bad the actual injury was.
How do you screen an event for PSIF potential?
The post recommends a simple screening step early in reporting that looks for significant energy exposure, line-of-fire risk, failed or missing critical controls, and whether a small change in timing or position could have made the outcome life-altering or fatal. It also suggests using a brief decision tree instead of long or vague forms.
How should a PSIF investigation be different from a routine incident investigation?
A PSIF investigation should focus on whether the controls meant to prevent catastrophic harm were present, effective, and used as intended. It should go beyond employee actions and examine the task, energy sources, control failures, plan changes, and operational factors like supervision, staffing, scheduling, and equipment condition.
What leading indicators are useful for preventing PSIFs?
The post highlights indicators tied to serious-risk controls in the field, such as critical control verification before high-risk tasks, pre-task plan quality for non-routine work, permit compliance, lockout/tagout verification quality, supervisor field presence, corrective action closure, and repeat events involving the same high-energy hazards.
