Workplace Hazard Identification and Risk Assessment: 6-Step Framework for Safety Management

A structured hazard identification and risk assessment (HIRA) framework enables organizations to systematically discover, evaluate, and control workplace risks.

Six-Step HIRA Framework

1. Hazard Identification
   • Hazard Inventory: Catalog all hazards: Physical (noise, radiation, vibration), Chemical (toxins, flammables, reactives), Biological (pathogens, allergens), Ergonomic (repetition, force, posture), Psychosocial (stress, violence, fatigue).
   • Job Safety Analysis (JSA/JHA): Decompose critical tasks into steps; identify hazards per step.
   • Inspections: Scheduled (daily, weekly, monthly), pre-use, management walkthroughs, third-party audits.
2. Risk Assessment
   • Likelihood × Severity: Qualitative (Risk Matrix: Low/Med/High/Critical) or Quantitative (FMEA, LOPA, QRA).
   • Exposure Assessment: Who, how many, frequency, duration, route (inhalation, dermal, ingestion, injection). Consider vulnerable groups (pregnant, young, immunocompromised).
3. Control Hierarchy (Hierarchy of Controls)
   • Elimination: Remove hazard (automate, redesign).
   • Substitution: Safer alternative (water-based vs. solvent).
   • Engineering Controls: Isolate hazard (guards, ventilation, enclosures, interlocks, noise damping).
   • Administrative Controls: Procedures, training, job rotation, signage, permits, maintenance schedules.
   • PPE: Last resort; appropriate selection, fit, maintenance, compliance monitoring.
4. Human Factors Integration
   • Error Analysis: Cognitive biases, fatigue, distraction, workload, interface design (HEART, THERP).
   • Training: Competency-based, scenario-driven, refreshed regularly.
   • Communication: Visual management, multilingual signage, toolbox talks, digital alerts.
5. Emergency Preparedness
   • Scenario-specific ERPs (fire, spill, release, medical, security, weather).
   • Drills (tabletop, functional, full-scale) with debrief and corrective actions.
   • Equipment: Eyewash/showers, spill kits, fire suppression, AEDs, gas monitors.
6. Continuous Monitoring and Improvement
   • Leading Indicators: Near-miss reports, safety observations, training completion, audit scores, PPE compliance.
   • Lagging Indicators: TRIR, DART, LTIR, severity rate, workers' comp costs.
   • Feedback Loops: Anonymous reporting, safety committees, suggestion systems.
   • Periodic Review: Annual HIRA refresh; trigger-based review (incident, change, regulation, technology).

Embedding this framework into the safety management system (ISO 45001, ANSI/ASSP Z10) transforms reactive compliance into proactive risk intelligence.
