Hazard Identification and Risk Assessment (HIRA)

Here’s a comprehensive overview of Hazard Identification and Risk Assessment (HIRA)β€”a fundamental and highly searchable workplace safety topic:


πŸ” Hazard Identification and Risk Assessment (HIRA)

βœ… Definition

HIRA is a structured process used to identify hazards, analyze or evaluate the risk associated with those hazards, and then determine appropriate ways to eliminate or control the risk.


πŸ“Œ 1. Key Elements of HIRA

ElementDescription
HazardAnything with the potential to cause harm (e.g., chemical, mechanical, electrical, physical, ergonomic, biological).
RiskThe likelihood that a hazard will cause harm and the severity of that harm.
Risk AssessmentProcess of evaluating risk based on likelihood and severity.
Control MeasuresActions to eliminate or minimize risks (e.g., engineering controls, PPE, training, safe work procedures).

πŸ› οΈ 2. HIRA Process Steps

  1. Identify Hazards

    • Observe the workplace

    • Review incident reports

    • Conduct job safety analysis (JSA)

    • Engage workers in walkthroughs

  2. Assess Risks

    • Evaluate likelihood and severity

    • Use a risk matrix (e.g., 5×5 scale)

  3. Evaluate & Prioritize Risks

    • Classify risks: Low, Medium, High, Extreme

    • Focus on high-priority risks first

  4. Implement Controls

    • Apply the Hierarchy of Controls:

      1. Elimination

      2. Substitution

      3. Engineering Controls

      4. Administrative Controls

      5. PPE

  5. Review and Monitor

    • Regular review of risks

    • Update based on changes in process, equipment, or incidents

Hazard TypeExamples
PhysicalNoise, vibration, radiation, heat
ChemicalAcids, solvents, gases, dust
BiologicalBacteria, viruses, fungi
ErgonomicRepetitive motion, poor posture
MechanicalUnguarded machinery, moving parts
ElectricalLive wires, arc flash risk
PsychosocialStress, harassment, fatigue

πŸ“˜ 5. Legal and Standard References

  • ISO 45001:2018 – Clause 6.1.2 (Hazard Identification & Assessment of Risks and Opportunities)

  • Factories Act (India) – Sections 7A & 41A

  • OSHA 29 CFR 1910 (USA)

  • BOCW Act – Rule 39 (Safety Officers)


🧠 6. Practical Uses of HIRA

  • Preparing Method Statements

  • Conducting Safety Walkdowns

  • Planning Work Permits (Hot work, Confined Space, etc.)

  • Developing Emergency Response Plans

  • Enhancing Training Programs
