Which statement describes a Class I, Division 2 location?

• A. Gases and vapors present under normal operations
• B. Gases and vapors handled but contained within closed containers
• C. Dust hazards present
• D. Fibers present

Answer: (B)

Class I, Division 2 locations are spaces where flammable gases or vapors are not normally in the air. They may be present only under abnormal conditions, and the design aims to keep any release contained within closed containers or equipment. So the statement about gases and vapors being handled but contained within closed containers fits that situation: the hazard exists only under unusual circumstances and is controlled by containment. In contrast, gases and vapors present under normal operations refer to Division 1, while dust hazards and fibers point to Class II and Class III locations, respectively.
