Which statement correctly identifies the storage classification for easily ignitable fibers?

• A. Class III, Division 2
• B. Class I, Division 1
• C. Class II, Division 1
• D. Class II, Division 2

Answer: (A)

Fibers that ignite easily fall under Class III locations. Within that class, Division 2 is used when the hazard is not normally present during everyday operation but can exist under abnormal conditions, such as in storage where fibers are kept but not actively processed. So a storage area for easily ignitable fibers is classified as Class III, Division 2: the fibers are readily ignitable, but the ignition hazard isn’t part of normal operation unless something abnormal occurs. If the fibers were being actively handled or processed where ignition could occur during normal work, that would be Division 1. The other classes don’t fit because Class I covers flammable gases or vapors, and Class II covers combustible dust, not fibers.
