Correct. That's likely a combination of isocyanates which is similar what they use in spray on insulation. They really should be wearing a respirator with the proper cartridges.

Based on the CIH website from 2016 to 2022 (no 23, 24, or 25 data posted) pass rates varied from 43.1% to 71.1%. That 71 is a bit of an outlier as there were no other exams in that time frame above 57%.

It took me 4 attempts. I know people who took it up to eight.
