NEBOSH IGC First-Attempt Success Guide 2026: How to Master the Scenario-Based Exam

NEBOSH IGC First Attempt Success Guide 2026 How to Master the Scenario Based Exam

Total Marks: 100
Passing Marks: 45
Exam Type: 100% scenario-based

Step 1: Reading & Understanding the Scenario

Read the scenario carefully 2–3 times.

  • First reading: Get a general idea of the organization.
  • Second reading: Focus on hazards, processes, and incidents.
  • Third reading: Understand the flow, positive/negative points, and clues for each task.

Break the Scenario into Logical Parts

Introduction:
Define your role, nature of the organization, floor/facility layout, number of workers, and nature of work.

Activities:
Describe main operations or processes.

Current Practices:
Explain what is being done, what is missing, and unsafe acts/conditions.

Incident / Near Miss:
Identify an accident or unsafe act, first aid response, losses, penalties, and whether incident investigation was conducted.

Use Highlighting Technique

Keep two highlighters:

  • Green: Positive points or good practices
  • Yellow: Negative points or gaps in safety

These highlights help you structure answers and focus on key areas.

Step 2: Writing Your Tasks (Answering Questions)

Word Count & Marks Correlation

NEBOSH marks are allocated based on points.

Rule of thumb:
30 words per mark

Example:
10 marks × 30 = 300 words

Answer Structure

  • Use short paragraphs (2–3 lines each).
  • Include technical terminology: hazards, risk, control measures, hierarchy of controls, near miss, unsafe act, PPE, safe system of work.
  • Avoid general words like “danger”.
  • Customize headings based on the scenario.
  • Use bullets where required.
