What does high potential mean?
Potential impact expresses the severity an event could have reached if conditions had changed in a plausible and closely related way. It is not about imagining any extreme outcome. There must be a credible relationship between the present danger, the possible exposure, and the inadequacy of the barriers. This assessment requires understanding the task, the energy sources involved, and the sequence of events.
A workplace incident without injury can reveal a significant weakness. For example, the accidental absence of a person from an impact zone does not equate to an effective barrier. The investigation needs to determine whether the favorable outcome was due to the functioning of the controls or to a coincidence that might not be repeated.
Actual severity and potential severity
The actual severity describes what occurred: injury, property damage, disruption, or no consequences. The potential severity describes a possible outcome under reasonably similar conditions. Both types of information are necessary and must be recorded separately. Confusing them can lead to an event without lost time receiving little attention despite revealing a mechanism capable of causing serious harm.
It is also not advisable to automatically assign high potential to all incidents. If the category ceases to discriminate, it loses its usefulness for prioritizing resources. The organization must define clear criteria and review examples to maintain consistency across centers. Internal preventive classification does not replace legal categories nor does it, on its own, determine reporting obligations to authorities.
How to assess potential in a reasoned way
The assessment begins with the known facts: what energy or agent was present, who could have been exposed, what path the event followed, and what controls should have prevented it. Then, plausible variations are analyzed, such as a person in their usual position or an operation that is performed repeatedly.
Facts, hypotheses, and pending data must be distinguished. If a critical condition is unknown, it is preferable to document the uncertainty and gather information. Technical expertise and job knowledge help avoid both minimization and alarmism. Bow-tie analysis can prioritize threats, barriers, and consequences when appropriate to the problem.
Initial response and information retention
The initial priority is to protect people and control the situation according to the organization’s procedures. Afterward, it is advisable to preserve relevant information without interfering with the care of those affected or maintaining a dangerous exposure to gather evidence. Photographs, locations, records, and testimonies can help reconstruct rapidly changing events.
The response should avoid premature conclusions or personal accusations. An explanation focused on “negligence” could close the investigation before understanding why the controls failed. Initial communication should state what is known, what remains to be done, and what temporary restrictions are necessary, using established channels and responsibilities.
Research on barriers and causes
Accident and incident investigations must examine planned barriers and their actual functioning. It is important to determine whether they existed, were available, were adequate, and could be used under the task conditions. Changes, maintenance, planning, and decisions that influenced the exposure must also be analyzed.
Actions are chosen based on these causes and the hierarchy of controls. Repeating a talk may be insufficient when the main problem is a lack of physical separation or a deficient maintenance system. Learning must translate into verifiable changes and criteria to ensure that the mechanism is no longer present.
Practical example
A load falls during a lifting operation in an area where people circulate at other times during the shift. No one is injured. The potential hazard assessment analyzes the weight, trajectory, usual position of personnel, and the delimitation of the area, without considering that the absence of injury demonstrates safety.
The investigation reviews planning, equipment, checks, and personnel separation. If a problem shared by other operations is identified, the scope of the measures is expanded. Before considering the event resolved, the application of controls in actual work is verified. This example illustrates preventive reasoning; it does not replace a technical evaluation of a specific maneuver.
Shared learning and follow-up
Sharing learning requires explaining the relevant mechanisms and controls, not just distributing an eye-catching photograph. Other departments need to be able to recognize if they have equivalent tasks and what they should check. It is helpful to assign responsibilities to assess the applicability of the measures, preventing a general communication from being considered a completed action on its own.
Monitoring distinguishes between temporary measures and permanent solutions and verifies their effectiveness. It also assesses whether the change has introduced new risks or depends on conditions that are difficult to maintain. The results may modify the planning of inspections, maintenance, training, or audits, depending on the weakness revealed by the incident.
Recording and interpretation of indicators
The record must include a description of the event, its actual severity, the justification for the potential impact, and the decisions made. It is advisable to review the consistency of the classifications to ensure that two centers do not interpret comparable events in opposite ways. Personal data is limited to what is necessary for preventive purposes.
An increase in reported high-potential incidents may reflect greater exposure, improved reporting channels, or changes in criteria. Therefore, the number in isolation does not demonstrate either improvement or deterioration. It must be interpreted in conjunction with working conditions and the effectiveness of interventions. Concealing incidents to lower the indicator eliminates important prevention opportunities.
