The safe distance of habitation from a hazardous chemical plant (TLV of its product < 1000 ppm) should be about ______________ kms?
Correct answer: D. 25
- A. 1
- B. 5
- C. 15
- D. 25
Explanation
For a hazardous chemical with a TLV below 1000 ppm, a large separation zone is recommended because even relatively small releases can affect nearby habitation; the commonly quoted safe distance is about 25 km. This is a conservative plant-siting guideline rather than a universal legal limit.
