§ 46.922. Functionality of various physical facilities of a food facility.

 (a)  Light bulbs: protective shielding.

   (1)  Except as specified in paragraph (2), light bulbs in use in a food facility shall be shielded, coated or otherwise shatter-resistant in areas where there is exposed food; clean equipment, utensils and linens; or unwrapped single-service and single-use articles.

   (2)  Shielded, coated or otherwise shatter-resistant bulbs need not be used in areas used only for storing food in unopened packages, if both of the following are accurate:

     (i)   The integrity of the packages cannot be affected by broken glass falling onto them.

     (ii)   The packages are capable of being cleaned of debris from broken bulbs before the packages are opened.

   (3)  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.

 (b)  Heating, ventilating and air conditioning system vents. Heating, ventilating and air conditioning systems in a food facility shall be designed and installed so that make-up air intake and exhaust vents do not cause contamination of food, food-contact surfaces, equipment or utensils.

 (c)  Design and installation of insect control devices.

   (1)  Insect control devices that are used in a food facility to electrocute or stun flying insects shall be designed to retain the insect within the device.

   (2)  Insect control devices shall be installed so that they meet the following requirements:

     (i)   The devices are not located over a food preparation area.

     (ii)   Dead insects and insect fragments are prevented from being impelled onto or falling on exposed food; clean equipment, utensils and linens; and unwrapped single-service and single-use articles.

 (d)  Toilet rooms shall be enclosed. A toilet room located on the premises of a food facility shall be completely enclosed and provided with a tight-fitting and self-closing door. This requirement does not apply to a toilet room that is located outside a food facility and does not open directly into the food facility (such as a toilet room that is provided by the management of a shopping mall).

 (e)  Outer openings shall be protected.

   (1)  Except as specified in paragraphs (2)—(5), outer openings of a food facility shall be protected against the entry of insects and rodents by use of the following:

     (i)   Filling or closing holes and other gaps along floors, walls and ceilings.

     (ii)   Having closed, tight-fitting windows.

     (iii)   Having solid, self-closing, tight-fitting doors.

   (2)  Paragraph (1) does not apply if a food facility opens into a larger structure, such as a mall, airport or office building, or into an attached structure, such as a porch, and the outer openings from the larger or attached structure are protected against the entry of insects and rodents.

   (3)  Exterior doors used as exits need not be self-closing if they are all of the following:

     (i)   Solid and tight-fitting.

     (ii)   Designated for use only when an emergency exists, and limited so they are not used for entrance or exit from the building for purposes other than the designated emergency exit use.

   (4)  Except as specified in paragraphs (2) and (5), if the windows or doors of a food facility, or of a larger structure within which a food facility is located, are kept open for ventilation or other purposes or a temporary food facility is not provided with windows and doors as specified in paragraph (1), the openings shall be protected against the entry of insects and rodents by one or more of the following:

     (i)   16 mesh to 25.4mm (16 mesh to 1 inch) screens.

     (ii)   Properly designed and installed air curtains to control flying insects.

     (iii)   Other effective means.

   (5)  Paragraph (4) does not apply if insects, rodents and other animals are absent due to the location of the facility, the weather or other limiting condition.

 (f)  Exterior walls and roofs: protective barrier. Perimeter walls and roofs of a food facility shall effectively protect the facility from the weather and the entry of insects, rodents and other animals.

 (g)  Outdoor food vending areas, overhead protection. If located outside, a machine used to vend food shall be provided with overhead protection except that machines vending canned beverages need not meet this requirement.

 (h)  Outdoor servicing areas: overhead protection. Servicing areas of a food facility shall be provided with overhead protection. However, if the area is used only for the loading of water or the discharge of sewage and other liquid waste, through the use of a closed system of hoses, the area need not be provided with overhead protection.

 (i)  Outdoor walking and driving surfaces: graded to drain. Exterior walking and driving surfaces of a food facility shall be graded to drain.

 (j)  Outdoor refuse areas: curbed and graded to drain. Outdoor refuse areas shall be constructed in accordance with Chapter 3 of the Pennsylvania Construction Code Act (35 P. S. § §  7210.301—7210.304) and shall be curbed and graded to drain to collect and dispose of liquid waste that results from the refuse and from cleaning the area and waste receptacles.

 (k)  Living or sleeping quarters, use prohibition. A room used as living or sleeping quarters, or an area directly opening into a room used as living or sleeping quarters, may not be used for conducting food facility operations.

 (l)  Living or sleeping quarters: separation. Living or sleeping quarters located on the premises of a food facility such as those provided for lodging registration clerks or resident managers shall be separated from rooms and areas used for food facility operations by complete partitioning and solid self-closing doors.
