Installing air curtains at the delivery entrance is intended to accomplish what?

• A. Block insects
• B. Improve lighting
• C. Eliminate dust
• D. Reduce heat loss

Answer: (C)

Air curtains create a fast-moving sheet of air at a doorway that acts as a barrier between indoors and outdoors. This continuous air stream pushes outside air, along with dust and other particulates, away from entering the space, helping keep the interior cleaner. In a delivery area, lots of dust can be stirred up by pallets, bags, and vehicles, so the curtain’s barrier reduces the amount of dust that sneaks in and settles inside. While these curtains can also help cut down on insects and reduce heat loss, the direct, most noticeable benefit in this setting is lowering dust entering the facility.
