Correct answer to question 9003
- C: Class III
Explanation
Locations with easily ignitible fibers or materials producing combustible flyings, such as textile mills and cotton gins, are Class III. Such fibers are not likely to be suspended in air in quantities that would make an ignitible mixture, which separates them from Class II dust locations.
