What must portable lighting equipment in Class III, Division 1 and 2 include?

Portable lighting equipment used in Class III, Division 1 and 2 environments must include handles and substantial guards to ensure safety and durability. The importance of handles is to provide ease of movement and to allow equipment to be transported safely, minimizing the risk of accidents or mishandling in potentially hazardous areas. Substantial guards help protect the lighting equipment from environmental factors such as dust, moisture, or physical impact, which can compromise the integrity of the equipment and pose safety hazards such as electrical shock or fire.

Focusing on safety in these classifications is crucial, as they pertain to areas that can be susceptible to ignitable fibers or flying objects which can create explosive atmospheres. Thus, equipped with proper handles and substantial guards, portable lighting can operate safely and maintain functionality in these challenging conditions.
