Match List-I (Tool / Technique) with List-II (Use in Audits / Plans) and select the correct code:

List-I

i. HAZOP

ii. MSDS

iii. Drills

iv. Incident-Controller

List-II

a. chemical info

b. process-design hazards

c. validate plans

d. coordinate on-site response

Choose the correct match :

1. A. i-b, ii-a, iii-c, iv-d (Correct answer)
2. B. i-a, ii-b, iii-d, iv-c
3. C. i-b, ii-d, iii-c, iv-a
4. D. i-c, ii-a, iii-b, iv-d

Correct Answer

Option A — i-b, ii-a, iii-c, iv-d

Detailed Solution & Explanation

The correct answer is i-b, ii-a, iii-c, iv-d.

Key Points

• Four tools, four functions:
  • i. HAZOP - b. Process-design hazards. A structured guide-word study of deviations in a process.
  • ii. MSDS - a. Chemical information. The safety data sheet giving properties, hazards, handling, storage and first-aid for a substance.
  • iii. Drills - c. Validate plans. Testing whether the emergency plan works in practice.
  • iv. Incident Controller - d. Coordinate on-site response. The person who takes charge at the scene.

Additional Information

• The natural grouping is worth noticing: HAZOP and MSDS are preventive — they supply knowledge before anything goes wrong — while drills and the incident controller belong to response, testing and executing the plan.
• An MSDS, now standardised internationally as the Safety Data Sheet (SDS) with 16 sections under the GHS, must be available for every hazardous chemical on site and is the first document consulted in a spill or exposure.
• The incident controller takes charge at the scene of the emergency; in a larger event the site main controller assumes overall command from the emergency control centre.
• HAZOP's distinguishing feature among hazard studies is its guide-word structure, which forces systematic coverage rather than relying on the team's imagination.
