Question 1358 Deck General

The correct answer is C) D. Camphor oil is classified as a Grade D material under the U.S. Coast Guard's hazardous materials regulations. Grade D materials are considered flammable liquids with a flashpoint below 100°F (37.8°C). This classification is based on the chemical properties and hazards associated with camphor oil, which is a volatile, flammable substance derived from the camphor tree. The other answer choices are incorrect because: A) A is not a valid grade classification, B) C is a different grade for less hazardous materials, and D) E is also not a valid grade used by the Coast Guard for hazardous materials.
