Question 754 Deck General

The correct answer is A) Chlorallylene. Chlorallylene is classified as a Grade B flammable liquid, which means it has a flashpoint below 73°F (23°C) and a boiling point at or above 100°F (37.8°C). This classification is based on the hazardous materials regulations set forth by the U.S. Coast Guard for licensed mariners. The other options are incorrect because Ethylene oxide (B) is a Grade A flammable gas, Paraldehyde (C) is a Grade C flammable liquid, and Allyl alcohol (D) is a Grade B flammable liquid, but not specifically a Grade B flammable liquid like chlorallylene.
