| Pillar | Key Concept | Real-World Example | |--------|-------------|---------------------| | | Every job has hidden energy sources (mechanical, chemical, thermal). | Lockout/Tagout (LOTO) prevents unexpected machine startup. | | 2. Risk Assessment Matrix | Likelihood × Severity = Priority. | A small chemical spill (low severity) vs. a toxic gas leak (high severity). | | 3. Human Factors | 80% of incidents are behavioral, not technical failures. | Fatigue, complacency, and "normalization of deviance" (e.g., skipping PPE because "nothing happened before"). | | 4. Engineering Controls | The hierarchy of controls: Elimination > Substitution > Engineering > Admin > PPE. | Ventilation hoods (engineering) over respirators (PPE) for chemical fumes. | | 5. Legal Compliance | OSHA (or local equivalent) standards are minimums, not goals. | Dr. Kumistry argues: "Compliance keeps you out of court; excellence keeps workers alive." | | 6. Emergency Response | The first 3 minutes after an incident determine survival rates. | Fire drills, spill kits, and medical triage plans. | | Fire drills
