Question 717 Deck General

The correct answer is A) Anhydrous ammonia. Anhydrous ammonia produces the most dangerous vapors compared to the other options. This is because anhydrous ammonia is a highly toxic and corrosive gas that can cause severe respiratory distress and chemical burns upon exposure. Regulations regarding the safe handling and storage of anhydrous ammonia are very strict due to its hazardous nature. The other options, such as camphor oil, methyl alcohol, and pentane, while also potentially hazardous, do not pose the same level of immediate danger as the concentrated, inhalable vapors produced by anhydrous ammonia.
