ACCIDENT CAUSATION THEORIES
- Domino Theory
- Loss Causation Model
- Multi-causality Accident Model
Prevent incident (important) ?
- Legal reasons
- Moral issues
- Business reasons
2 types of incidents
- Long term injuries
- Short term injuries
Heinrich’s Domino Theory
- Ancestry & Social Environment – Personal traits (e.g., carelessness, recklessness) influenced by upbringing.
- Fault of the Person – Unsafe behaviors, like not following safety rules.
- Unsafe Acts or Conditions – The actual hazard, such as a slippery floor or not wearing protective gear.
- Accident – The unsafe act or condition leads to an accident.
- Injury – The accident results in harm, like a broken arm.
Loss Causation Model
- Lack of Control – Poor safety management (e.g., no proper training, weak policies).
- Basic Causes (Root Causes) – Deeper reasons like poor work culture, bad habits, or lack of supervision.
- Immediate Causes – Unsafe actions (e.g., rushing, ignoring safety rules) or unsafe conditions (e.g., faulty equipment).
- Incident – The unsafe act or condition leads to an accident or near-miss.
- Loss – The final result, which could be an injury, damage, or financial loss.
Multiple Causality Model (MCM)
- Human Factors – Mistakes, lack of training, fatigue, stress, or poor decision-making.
- Technical Factors – Equipment failure, design flaws, poor maintenance.
- Environmental Factors – Poor lighting, extreme temperatures, slippery floors, or noise.
- Organizational Factors – Lack of safety policies, poor supervision, or rushing deadlines.
Principles of Incident
Prevention
- Pengurusan dan pekerja mesti bekerjasama sepenuhnya
- Pencegahan insiden adalah pengurusan yang baik
- Pengurusan atasan mesti memimpin.
- Mesti ada polisi OSH
- Mesti mempunyai organisasi dan sumber untuk melaksanakan dasar
- Maklumat terbaik yang tersedia (dan teknologi) mesti digunakan.
Tye-Pearson Accident Ratio
For every 1 fatal or serious injury, there were:
a) 3 minor injuries (workers absent for up to 3 days).
b) 50 injuries needing only first aid.
c) 80 accidents that caused property damage.
d) 400 near misses (incidents that almost caused harm)
Tye Pearson Accident Ratio (important)
Prevention: Small incidents (near misses) can lead to serious accidents if ignored.
Workplace Safety: Companies should focus on reducing minor incidents to prevent major injuries.
Supports Safety Laws: Contributed to improving safety standards, including the Health and Safety at Work Act (1974).
