The 5 Steps of Risk Assessment (NEBOSH Approach)

Identify Hazards – What could cause harm?

Decide Who Might Be Harmed & How – Workers, contractors, visitors, or the public.

Evaluate the Risks & Decide on Controls – Assess severity, likelihood, and existing controls.

Record Findings & Implement – Document the assessment and ensure actions are followed.

Review & Update – Monitor effectiveness and revise regularly or after changes.

Examples of Hazards, Risks, and Control Strategies
Example 1: Construction Site – Working at Height

Hazard: Unprotected scaffolding at 6 meters.

Risk: Fall from height leading to serious injury or fatality.

Risk Rating: Likelihood = High, Severity = High → High Risk.

Control Measures (Hierarchy of Control):

Elimination: Use extendable tools to avoid working at height where possible.

Substitution: Replace scaffolding work with ground-assembled prefabricated structures.

Engineering Controls: Install guardrails, mid-rails, and toe boards on scaffolds.

Administrative Controls: Provide work permits, supervision, and training on safe practices.

PPE: Safety harnesses with secure anchor points.

Example 2: Manufacturing Plant – Chemical Handling

Hazard: Use of corrosive cleaning chemical.

Risk: Skin burns, eye injury, respiratory irritation.

Risk Rating: Likelihood = Medium, Severity = High → Medium-High Risk.

Control Measures:

Elimination: Stop using hazardous chemical if unnecessary.

Substitution: Use a less harmful, non-corrosive cleaning agent.

Engineering Controls: Local exhaust ventilation (LEV) to remove fumes.

Administrative Controls: Safety Data Sheets (SDS), training on safe handling, restricted access.

PPE: Chemical-resistant gloves, goggles, face shields, aprons.

Example 3: Office Environment – Ergonomic Hazards

Hazard: Poor workstation design (non-adjustable chairs, awkward screen height).

Risk: Musculoskeletal disorders, eye strain, fatigue.

Risk Rating: Likelihood = High, Severity = Low → Medium Risk.

Control Measures:

Elimination: Automate repetitive manual tasks where possible.

Substitution: Use ergonomic furniture with adjustable settings.

Engineering Controls: Install sit-stand desks, monitor risers.

Administrative Controls: Implement “work-break” policy, provide training on posture.

PPE: (Least effective – not usually applicable here).

Training Methodology

Interactive Workshops: Hazard spotting exercises with real workplace scenarios.

Group Work: Teams prepare a risk assessment table for case studies.

Practical Assessment: Each participant conducts a mini risk assessment of a chosen workplace.

Role Play & Discussions: Review risk ratings and debate control strategies.
