Question

Quizplus · Accepted Answer

Class III locations are locations where easily ignitable fibers or materials producing combustible flyings are handled, processed or used, but which are not likely to be suspended in air in quantities sufficient to produce ignitible mixtures. Therefore, portable lighting equipment used in Class III, Division 1 and 2 locations shall have both handles and substantial guards to protect the lamps from damage and to minimize the possibility of breaking the enclosure. Sealed casings are not necessarily required, but the fixtures should be designed to keep out large particles and dust. Positive airflow is not specifically required, and cross-wiring is not applicable to portable lighting equipment.
