In hazardous locations, what type of ignitable materials are found in Class 3 Division 1 areas?

• A. Liquid fuels
• B. Flammable vapors
• C. Easily ignitable fibers
• D. Explosive gases

Answer: (C)

In hazardous locations classified as Class 3 Division 1, you typically find easily ignitable fibers. This classification focuses on areas where the presence of flammable materials can create an explosive atmosphere. Class 3 specifically refers to materials that can ignite through friction, heat, or static electricity. In this context, easily ignitable fibers such as those found in textiles, paper, or other materials can accumulate and pose a significant fire risk. These fibers are capable of sustaining combustion when exposed to an ignition source. Understanding this classification helps in implementing necessary safety measures, such as appropriate electrical installations and equipment designed to minimize ignition risks from these materials. While other classifications mention flammable liquids, vapors, or explosive gases, Class 3 emphasizes the particular danger posed by fibers and similar combustibles, making them the correct answer for this specific class and division of hazardous locations.
