Why should doors be kept closed in storage areas?

• A. To prevent pest infestation.
• B. To prevent heat loss.
• C. To improve lighting.
• D. To reduce noise.

Answer: (A)

Keeping doors closed in storage areas is primarily about excluding pests. Pests such as rodents and insects are attracted to food, packaging, and spills, and an open door provides an easy entry point. Once inside, they can contaminate products, damage packaging, and spread bacteria or viruses, creating safety and regulatory problems. Closing doors helps maintain a sanitary environment and supports pest-control programs by limiting access. While there can be secondary effects like some heat retention, those are not the main reason, and closing doors doesn’t purposefully enhance lighting or reduce noise.
