Every HSE leader in chemical manufacturing knows the rhythm. The monthly safety meeting opens with a slide deck with data points of the Total Recordable Incident Rate (TRIR), Days Away, Restricted, or Transferred (DART), near-miss counts, first-aid cases, and days since last recordable. The room reviews the numbers, discusses trends, and moves on. These metrics are familiar because they have been the backbone of safety reporting for decades, but they are also, by definition, a record of things that have already gone wrong.
The industry has talked about leading indicators for years. The Center for Chemical Process Safety (CCPS) has published the Process Safety Metrics Guide for Leading and Lagging Indicators, and API RP 754 gave the refining and petrochemical industries a structured way to classify process safety indicators across a leading-to-lagging continuum. Under API RP 754, Tier 1 indicators are the most lagging, while Tier 4 indicators are the most leading and focus on operating discipline and management system performance. That is the side of the model where many common leading indicators sit, including inspection completion, safety observations, and other measures that show whether critical safety processes are being followed. Yet when we ask HSE leaders at chemical manufacturing facilities which safety leading indicators they actively track and act on, the answers still tend to cluster around inspection completion rates, near-miss reporting volume, and safety observation counts. Those data points are useful, but they are also incomplete because they often miss one of the most practical Tier 4-style signals available to the plant: whether the people assigned to hazardous work have current, proven competency to perform it.
What Are Safety Leading Indicators?
Safety leading indicators are proactive measures that help teams identify risk before an incident occurs. In chemical manufacturing, they may include inspection completion, open corrective actions, overdue maintenance, safety observations, near-miss trends, and workforce competency gaps. Lagging indicators, such as TRIR and DART, measure what already happened.
Competency data can be helpful here to help fill in the gaps. Most plants already have records that show who is qualified to do what, where gaps exist, what is about to expire, and which critical roles are running thin. The problem is that this data is usually treated as an audit record, not as a safety leading indicator.

Leading and Lagging Indicators in Safety: The Difference Between Counting and Predicting
The difference between leading and lagging indicators determines whether your safety program is reactive or predictive. Lagging indicators measure outcomes. For example, TRIR tells you how many recordable incidents occurred per 200,000 hours worked, while DART tells you how many of those incidents involved days away, restricted duty, or job transfer. Both are essential for benchmarking, but neither really tells you anything about what is most likely to happen next.
Leading indicators, by contrast, are the upstream signals that measure the conditions and behaviors that precede incidents. CCPS defines a leading indicator of staff competence as the percentage of employees involved in hazardous operations who have received training and have proven their competency. The language does not say completed training; it says proven competency. There is a big difference between a course completion record in an LMS and a validated, assessor-observed demonstration proving an operator can actually perform the task.

The leading indicators on the right side of the chart are not incident reports; they are early warning signs. When competency gaps increase, when critical assessments begin to expire, or when new hires are assigned to hazardous operations before field validation is complete, the conditions for risk are forming before an incident occurs. The problem is that most plants cannot see those signals clearly because competency data is fragmented across spreadsheets, binders, LMS reports, and disconnected systems that were never designed to surface workforce readiness trends.
What HSE Leaders Are Missing
Consider what a real-time competency dashboard would reveal if it existed in most chemical plants today. You might see that 14 percent of your operators on PSM-covered units have at least one critical competency that expired in the last 90 days. You might see that your night shift on Unit 3 has been running with two operators whose emergency shutdown assessments have been overdue since the last procedure revision. You might see that the three newest hires in your reactor operations group have completed classroom training, but they have not quite passed their field performance assessments.
Competency data can show HSE leaders:
- Which operators are validated on safety-critical tasks
- Which competencies are expired or nearing expiration
- Where field assessments are overdue
- Which units or shifts have thin critical-role coverage
- Which procedure changes should trigger reassessment
- Which contractors or new hires have not yet been validated for assigned work
None of those data points have shown up in your TRIR yet, generated a near-miss report, or triggered an OSHA citation, but each of them represents a degradation in the safety barrier between normal operations and a recordable event. They are like holes in Swiss cheese, lining up, and without the right data to see them, the first indication that something is wrong arrives in the form of an incident investigation.
It is not that HSE leaders are ignoring workforce competency, because they care deeply about it. It is just that, often, the tools most plants use to track competency were never built to function as a safety intelligence layer. A spreadsheet can store a date, but it cannot alert you when 30 competency expirations are occurring in the same operating area during the same quarter. An LMS can confirm that a training or learning module was completed, but it cannot tell you whether the operator demonstrated the ability to actually execute the procedure under specific field conditions.
An LMS can confirm that training was completed, but chemical manufacturers also need proof that operators can perform the work under real field conditions. Learn why operator competency verification requires task-level validation, current evidence, and a clear connection between training records and operational readiness.

Competency Signals That Should Trigger Action
If competency data is treated as a safety leading indicator, it can trigger action before a gap turns into an incident. Examples of these gaps could include:
- A rising competency gap percentage on a PSM-covered unit
- Multiple expired assessments tied to the same procedure
- New hires assigned to hazardous operations before field validation is complete
- Critical role coverage gaps on nights, weekends, or high-risk shifts
- Contractors cleared for site access without task-level validation
- Procedure revisions that have not triggered reassessment workflows
These signals may not always look urgent in isolation, but when they appear together, they can give HSE leaders a clearer view of where risk is building before an incident occurs.
From Compliance Record to Safety Leading Indicator
The shift we are describing with data is not just to collect more data. Most plants actually already have more data than they realize. The shift is more about elevating the data from a compliance artifact that only gets reviewed during audits, into an operational safety metric that is reviewed alongside metrics like TRIR and DART each month.
Competency data can become a safety leading indicator when it is tracked as a trend, reviewed regularly, and used to trigger action before work continues. To use this data, though, it has to evolve from a static record into data that can be referenced and analyzed to determine current risk, future exposures, and what can be done to improve readiness.
Competency gap percentages become an important KPI, as leaders can track the trend lines of expiring assessments, just like near-miss trend lines are tracked. It also means building a workflow where a spike in overdue competency validations on a specific unit triggers the same attention to detail as a spike in first aid cases. HSE teams need visibility into this competency data so that it can be used as a workforce readiness tool that is as current and granular as the process safety data coming off the control system.
How to Use Competency Data as a Safety Leading Indicator
A practical way to start is to look at competency data through the same lens HSE teams already use for other safety leading indicators: current status, trend direction, concentration of risk, and action required. For competency data, that means asking questions like:
- What percentage of employees in hazardous operations have proven competency for their assigned work?
- Which critical competencies are expired, overdue, or nearing expiration?
- Where are procedure changes creating reassessment needs?
- Which units, shifts, or crews have the highest concentration of competency gaps?
- Are corrective actions closing the gaps, or are they continuing to accumulate?
The answer to these questions gives leaders a more practical view of workforce readiness, and it also helps connect competency assurance to the safety conversations already happening across the plant. Instead of reviewing competency data only before an audit, HSE teams can use it to understand where risk is increasing, where resources need to be focused, and where work should pause until validation is complete.
This approach is not theoretical. The upstream energy sector has been operating this way for years. Offshore operators in the North Sea and the Gulf of Mexico have long treated competency assurance as a core safety barrier, not because they are more sophisticated, but because the consequences of getting it wrong in those environments made the investment obvious. Chemical manufacturing, while operating at the same hazard levels, does so with a fraction of the workforce competency infrastructure as many energy operators do.
Chemical manufacturers do not need to copy the upstream energy model exactly. The operating environment, asset base, and workforce structure are different, but the principle carries over clearly: when the work is hazardous, competency assurance should be visible, current, and connected to the decisions that determine who performs the work.
Competency Data Should Trigger Action Before an Incident Does
A safety leading indicator only works if leaders can act on it. Expired competencies, overdue field assessments, thin role coverage, and missing reassessments after procedure changes should not sit quietly in a spreadsheet. They should trigger review, reassignment, reassessment, or a pause before work continues. The goal is not more data. It is earlier visibility into where workforce risk is building.
How Kahuna Makes Competency Data Visible and Actionable
Chemical manufacturers are navigating a more complex operating environment. Experienced operators are retiring and taking knowledge with them, contractors and new hires are moving into critical work faster, procedures continue to change, and OSHA PSM still requires employers to verify that covered-process employees have received and understood required training. At the same time, many plants are still trying to manage competency evidence through spreadsheets, LMS reports, binders, and supervisor memory.
Each challenge connects back to the same gap: chemical manufacturers need a better way to document, validate, and act on workforce competency across the organization. For many plants, competency data still behaves like a static compliance record instead of a living operational dataset.
Kahuna’s skills and competency management platform was built to close the gaps that chemical manufacturers are facing. Kahuna provides HSE leaders with real-time visibility into competency status across every operator, every unit, and every shift. Expiring competencies surface automatically. Assessment workflows are triggered by procedure revisions, role changes, and Management of Change events. Gap analysis is continuous, not something that gets reconstructed in the weeks before an audit. And every data point, from the initial skill assignment to the most recent field assessment, is time-stamped, traceable, and tied to a specific assessor and a specific operating procedure revision.
For HSE leaders who have spent their careers fighting to move safety programs from reactive to predictive, competency data is the leading indicator that has been hiding in plain sight. Kahuna makes it visible, actionable, and defensible.
The question is not whether your workforce has competency gaps because every plant does. The question is whether you can see them before they show up in your incident log. This analysis is what separates a safety program that reports on the past from one that prevents incidents in the future.

FAQs About Safety Leading Indicators and Competency Data
What are examples of safety leading indicators in chemical manufacturing?
Safety leading indicators in chemical manufacturing may include overdue inspections, open corrective actions, near-miss trends, safety observations, overdue maintenance, expired competency assessments, critical role coverage gaps, and incomplete field validations for hazardous work.
How can competency data be used as a safety leading indicator?
Competency data becomes a safety leading indicator when it shows where workforce readiness risk is building before an incident occurs. Examples include rising competency gaps on PSM-covered units, expiring critical assessments, overdue field validations, and new hires or contractors assigned to hazardous work before validation is complete.
What competency metrics should HSE leaders track?
HSE leaders can track competency gap percentage, expiring critical assessments, overdue field validations, reassessment status after procedure changes, critical role coverage by shift, and validation status for employees and contractors assigned to hazardous operations.
Why should competency data be reviewed alongside TRIR and DART?
TRIR and DART show what has already happened, while competency data can show where workforce readiness is starting to drift before that drift contributes to a safety event, quality issue, audit finding, or operational disruption.
How does operator competency tracking support process safety metrics?
Operator competency tracking gives HSE and operations leaders visibility into whether people assigned to hazardous work have current, validated capability for the tasks they perform. When tracked by unit, shift, role, and procedure, that data can help identify process safety risk before it appears in incident reports.
How does competency data support process safety metrics?
Competency data supports process safety metrics by showing whether the people assigned to hazardous work have current, validated capability for the tasks they perform. When an operator’s qualification expires, a field assessment is overdue, or a crew is assigned without enough validated coverage, the risk condition exists before an incident occurs. Tracking those signals by unit, shift, role, and procedure gives HSE and operations leaders another way to see where process safety risk may be building.
