Safety KPI Dashboard: Professional Field Notes

1) Purpose of a site safety KPI dashboard

A safety dashboard turns daily activity into a consistent management view. By combining lagging indicators (TRIR, LTIR, DART, severity) with leading indicators (audits, observations, near misses, action closure), teams can spot risk patterns before they become injuries. A single period label keeps reporting aligned across projects and subcontractors.

2) Why the 200,000-hour base is used

Incident rates are normalized to allow fair comparisons between crews of different sizes. The 200,000-hour base approximates 100 people working 40 hours per week for 50 weeks. In this calculator, every rate uses the same base, so a move from 0.80 to 1.20 TRIR is a real performance change, not a staffing artifact.

3) Setting practical targets for lagging rates

Many construction programs set TRIR targets around 1.0–2.0 depending on scope, while LTIR and DART targets are often lower because they focus on more serious outcomes. Use contract requirements where available, then refine targets as the project stabilizes. Consistency matters more than chasing perfect numbers across different phases.

4) Leading indicators that move results

Leading activity should be scaled to exposure. Observation rate and near miss rate are calculated per 200,000 hours, which helps you compare a 10,000-hour month to a 60,000-hour month. As a working guide, aim for regular observations per shift, weekly supervisor audits, and corrective actions that close within the same reporting window.

5) Audit compliance and action closure performance

Audit compliance shows execution discipline: (completed ÷ planned) × 100. Closure rate shows learning discipline: (closed ÷ total) × 100. When audit compliance is high but closure lags, hazards are being found but not eliminated. When closure is high but audits are low, you may be reacting only after issues surface.

6) Training hours per person

Training volume is useful only when tied to headcount. The calculator converts training hours into training hours per person, which helps teams avoid inflated totals during peak staffing. Track this metric alongside new-hire onboarding and critical task refreshers, especially before high-risk activities like lifts, energization, and confined access.

7) Using the overall score responsibly

The overall score blends multiple indicators to provide a quick executive snapshot. Use it to compare periods and highlight improvement, but always review the component KPIs. A low TRIR with weak leading indicators can signal under-reporting or limited engagement, while strong leading indicators with a brief spike can signal honest reporting and active control.

8) Monthly review rhythm and decision triggers

Adopt a fixed cadence: weekly data entry, monthly management review, and quarterly target calibration. Trigger corrective action when TRIR or DART trends upward for two consecutive periods, when audit compliance drops below plan, or when closure falls under a program threshold such as 90%. Use the CSV/PDF outputs to keep discussions factual and repeatable.

FAQs

1) What should I enter as hours worked?

Use total labor hours for the reporting period, including subcontractors if they are within your safety program scope. If you separate populations, run separate dashboards to keep rates comparable.

2) How do I interpret TRIR versus DART?

TRIR counts all recordable cases normalized by hours. DART focuses on cases with days away, restrictions, or transfers, so it often reflects higher severity. Track both to understand frequency and impact.

3) Why does the calculator show “—” for some KPIs?

If a denominator is zero, rates cannot be computed reliably. For example, zero hours worked makes incident rates undefined. Enter realistic hours to calculate normalized performance.

4) Are near misses and observations required?

No, but they strengthen the dashboard. These leading indicators help forecast risk and measure engagement. If you do not track them yet, start simple and build consistency over time.

5) How should I use the previous period comparison?

Turn it on when you have stable reporting intervals, such as month-to-month or quarter-to-quarter. Percentage change is most useful when hours are similar; otherwise, review the raw counts and exposure.

6) What target values should I use?

Start with client, insurer, or corporate requirements. If none exist, set targets based on recent internal performance and planned improvements. Update targets at major phase changes to stay realistic.

7) Does a higher overall score guarantee better safety?

No. A score summarizes multiple signals, but it cannot replace field verification. Use it to prioritize reviews, then confirm controls through observations, audits, and direct engagement with supervisors and crews.
