Construction Safety Calculator Guide
Safety by the Numbers
Safety isn't just a feeling; it's a metric. The construction industry tracks safety performance using specific formulas to lower insurance rates and, more importantly, save lives.
TRIR (Total Recordable Incident Rate)
The standard benchmark for safety performance.
Formula: (Number of Incidents × 200,000) / Total Hours Worked
The "200,000" represents 100 workers working 40 hours/week for 50 weeks.
The "Fatal Four"
Falls (33% of deaths)
The #1 killer in construction.
- Prevention: Guardrails, safety nets, and personal fall arrest systems (harnesses) for any height over 6 feet.
Struck-By
Hit by vehicles or falling objects.
- Prevention: High-visibility vests, hard hats, and designated vehicle paths.
