The design and installation provisions shall be as prescribed in §§ 87-51 through 87-53 (relating to design and installation of equipment and utensils).
Mobile food-service establishments shall also meet the following requirements:
A. 
Power equipment shall be installed so as to eliminate the danger from electrical shock.
B. 
Service openings may be no larger than necessary to carry out the food operation and shall be a size to prevent health hazards. Service openings shall be kept closed except when food is actually being served. When the mobile unit is in motion, the openings shall be covered with a solid material so as to prevent the entrance of dust, flies and other sources of contamination.
C. 
Equipment shall be installed to protect unwrapped foods from customer handling.
D. 
The driver's compartment as well as the food preparation and storage areas shall be enclosed and protected against the entrance of airborne contaminants and vermin. However, the licensor may accept a mobile food-service establishment of different design whenever only commercially package or canned foods are sold and the contents are not removed from the original package prior to being sold.
E. 
The driver's compartment shall be separated from the food service, storage and preparation areas by a wall. The wall on the side of the food compartment shall meet the wall requirements of § 87-151 (relating to floors, walls and ceilings). However, a wall need not be provided if the doors of the driver's compartment are self-closing and cannot be propped open when the mobile unit is in motion. Doors used to gain entrance from one part of the mobile unit to another shall be self-closing and constructed from solid material.
F. 
The hot food storage facilities in a mobile food-service establishment shall be capable of operating whenever perishable or potentially hazardous foods are stored therein.
