Tracks 'near misses' — incidents that didn't result in injury / damage but had potential to. Critical leading indicator for preventing serious incidents. Per Heinrich's pyramid: 300 near-misses → 29 minor injuries → 1 major.
NM #2026-89, 12-May-2026, 14:30. Location: Tower crane jib base. Description: Crane bracelet swung within 0.5 m of worker; worker stepped back unharmed. Potential: Major (could have caused serious injury). Cause: Crane operator unaware of worker's location. Action: Communication protocol + warning bell on every swing. Closed: 18-May-2026 after retraining of crane operators.
Heinrich's Triangle (1931, refined by Bird 1969) is the single most important model in occupational safety: for every 1 major injury, statistical data shows ~29 minor injuries and ~300 near-misses occur. The bottom of the pyramid — near-misses — is where prevention happens; the top — fatalities — is where prevention failed.
A construction site that reports zero near-misses is not safe; it is silent. Workers are scared to report, supervisors are punishing reports, or the culture treats only injuries as worth recording. The number of recorded near-misses is therefore a leading indicator of safety performance — high numbers mean the system is working, not failing.
Under ISO 45001:2018 (OHSMS — Occupational Health + Safety Management System) and the Code on Occupational Safety, Health + Working Conditions 2020, near-miss reporting is a mandatory element of the safety system. The Near-Miss Register is the project's primary tool for converting these reports into corrective action.
Reporting flow (10 steps): 1. Observer / worker / supervisor identifies a near-miss event 2. On-site reporting within 24 hours — verbal to supervisor + written entry into register 3. Initial classification by Safety Officer — potential severity (Major / Moderate / Minor) 4. Investigation — for Major potential, full RCA within 7 days; Moderate within 14 days; Minor within 30 days 5. Root cause analysis — using 5 Whys / Fishbone / Bow-tie 6. Corrective actions — Engineering (eliminate hazard) > Administrative (procedure) > PPE (last line) 7. Communication — toolbox talk within 7 days; learning shared site-wide 8. Tracking — until corrective action verified effective 9. Trend analysis — monthly review by HSE manager; recurring activities / locations flagged 10. Audit trail — register reviewed in HSE Steering Committee + project closeout audit
What counts as a near-miss: - A worker steps back just before a falling object lands - Crane bracelet swings within 0.5m of person - Scaffold board cracks but no fall - Electrical short — sparks but no shock - Worker climbs without harness — supervisor catches before fall - Vehicle reverses without spotter — pedestrian moves in time - Material slips from sling — lands on empty area not occupied - Confined-space entry without permit — no gas exposure but could have been
Categories by hierarchy of control: - Elimination — remove the hazard entirely - Substitution — replace with safer alternative - Engineering controls — guards, interlocks, barriers - Administrative — procedures, training, signage - PPE — last resort, never the primary control
1. Blame culture — workers punished for reporting; reports dry up; site becomes 'zero near-miss' (read: zero reporting, high actual risk).
2. Reports treated as paperwork — entered but no investigation; no corrective action; system theatre; workers stop bothering.
3. Only injuries recorded — near-misses ignored because no harm done; missing the leading indicator entirely.
4. No trend analysis — register full of entries but never aggregated; recurring patterns at same location / activity not caught.
5. Corrective actions parked — same near-miss happens 3 times because action item from first incident never closed.
6. No toolbox talk follow-through — learning not shared with workforce; same crew about to do same task makes same mistake.
7. 5 Whys done superficially — "worker was careless" treated as root cause; doesn't address systemic gap (training / procedure / equipment).
8. PPE-only corrective action — every near-miss closed by "wear PPE"; ignores engineering controls.
9. Reports anonymous but punitive after — system says "blame-free" but supervisor finds out and acts; trust breaks.
10. HSE Officer reports own incidents only — supervisors / engineers don't report their own near-misses; data biased toward worker-observed events; managerial decisions / planning errors undetected.
