Match each hazard in List I with the measure that addresses it in List II.

List I

A. Dust explosion

B. Structural damage from an explosion

C. Product contamination

D. Grain breakage

List II

1. Explosion relief panels

2. Dust extraction at transfer points

3. Fewer transfers and lower drop heights

4. Fully enclosed conveyors

Select the correct match.

  • A.A-2, B-1, C-4, D-3
  • B.A-1, B-2, C-4, D-3
  • C.A-2, B-4, C-1, D-3
  • D.A-3, B-1, C-4, D-2

Answer: A

Correct answer: A-2, B-1, C-4, D-3

Four hazards with four distinct measures. Dust extraction at the transfer points attacks the explosion at its source by removing the fuel. Relief panels limit the structural damage if one occurs anyway. Fully enclosed conveyors keep the product clean. And fewer transfers with lower drop heights is the answer to breakage, which is a design decision rather than a fitting.
