What is the minimum lighting requirement in footcandles for walk-in refrigeration units and dry storage?

The minimum lighting requirement for walk-in refrigeration units and dry storage areas is established to ensure safety and functionality. A requirement of 10 footcandles (FC) is deemed sufficient because it provides enough illumination for individuals to safely navigate these spaces and adequately inspect the contents. This lighting level supports operational efficiency, allowing staff to perform tasks such as inventory checks and maintenance without risk of injury or error due to inadequate visibility.

Other lighting levels, while potentially useful in specific circumstances, exceed what is necessary for the basic operational needs in these environments, making 10 footcandles the appropriate standard for walk-in refrigeration units and dry storage.
