Question 318 Deck General
70% to passYou are loading epichlorohydrin onto your barge. According to the Chemical Data Guide, you could expect to detect a leak by smell if the concentration in air was at least _______________.
A
2 ppm
B
10 - 25 ppm
C
40 ppm
D
105 ppm
AI Explanation
The correct answer is B) 10 - 25 ppm. According to the Chemical Data Guide for Bulk Shipment, the detectable odor threshold for epichlorohydrin is 10-25 ppm in air. This means that a leak or spill of epichlorohydrin would likely be detected by smell if the concentration in the surrounding air was at least 10-25 ppm. The other options are incorrect because 2 ppm is below the detectable odor threshold, 40 ppm is outside the 10-25 ppm range, and 105 ppm is significantly higher than the detectable level.
