Except as specified in section 1809.2, light bulbs shall be shielded, coated, or otherwise shatter-resistant in all areas where food is examined, processed, or stored, and where equipment or utensils are cleaned.
Shielded, coated, or otherwise shatter-resistant bulbs need not be used in areas used only for storing food in unopened packages, if:
An infrared or other heat lamp shall be protected against breakage by a shield surrounding and extending beyond the bulb so that only the face of the bulb is exposed.
