Shielded, coated, or otherwise shatter-resistant bulbs need not be used in areas used only for storing prepackaged food in unopened packages, if the integrity of the packages cannot be affected by broken glass falling onto them and the packages are capable of being cleaned of debris from broken bulbs before the packages are opened.
