GUIDELINES FOR SANITARY
CONSTRUCTION OF AIRCRAFT GALLEYSAND GALLEY COMPONENTS

PREFACE

This document contains criteria for the sanitary construction of aircraft galleys and components or related equipment. It has been developed as a guideline for the manufacturer's of airframes, manufacturers of aircraft galleys and components or related equipment, the airline industry, and public health personnel to achieve and maintain a higher level of sanitation in aircraft galleys and to provide for uniformity in sanitary construction.

The Commissioner of Food and Drugs, Food and Drug Administration (as delegated by the Secretary, DHHS, and under authority of the Public Health Service Act, Public Law 410, Seventy-Eighth Congress), is authorized to promulgate regulations for the prevention, introduction or the spread of communicable diseases. The Interstate Conveyance Sanitation Regulations, 21 CFR Part 1250, requires the owner or operator of the conveyance to submit plans to the Food and Drug Administration for review of construction and reconstruction of aircraft. The requirements set forth herein are the criteria by which the plans and constructed equipment will be evaluated by authorized FDA representatives. The nearest office of the Food and Drug Administration should be contacted for procedural information on plan submittal, or other matters.

As improved methods and techniques of manufacturing or fabrication are developed and as changes in the airline industry occur, changes in the requirements for sanitary practices and procedures must occur. Such developments will be included in subsequent editions of this publication.

Further, this publication does not preclude the need to meet the requirements of other governmental agencies having responsibility concerning aircraft.

Inquiries or comments regarding this publication or other interstate conveyance sanitation related matters should be directed to the appropriate Food and Drug Administration office.

SECTION 6 - AIRCRAFT AND GALLEY POTABLE WATER SYSTEMS

6.1 POTABLE WATER STORAGE TANKS:

Potable water tanks shall be constructed in a manner that will prevent contamination of water. They shall be independent and have no common partition with a tank holding non-potable water or other liquids. Tanks shall be constructed of CORROSION-RESISTANT, NON-ABSORBENT and NON-TOXIC material. Interior welded or soldered SEAMS and JOINTS shall be free of rough surfaces. Tanks shall be designed to permit complete draining and flushing when the aircraft is in its normal parked position. If a protective coating is used, such coating shall be in compliance with the Food Additives Amendment of the Federal Food, Drug, and Cosmetic Act. Evidence of Compliance of drinking water contact coatings and materials meeting the Environmental Protection Agency's requirements (under Safe Drinking Water Act, Toxic Substances Control Act, and Federal Insecticide, Fungicide and Rodenticide Act, see Federal Register, V. 44, N. 141, pp. 42775-8, July 20, 1979) may be acceptable in lieu of FFDCA requirements.

Aircraft galley potable water tanks may be filled independently or from the main potable storage tanks aboard. If filling is to be from the main tanks, it shall be via a continuous, closed piping system, Shut-off valves may be installed in these lines. If filling is directly to the galley tanks, the water filling connection shall be quick-coupling, of a size or type different from other service connections on the aircraft (no greater than 3/4 inch). The connection shall be clearly labeled "Potable Water Filling" and be provided with properly secured protective dust-tight cover. The fill line shall be completely independent and not cross-connected with any line used for non-potable liquids.

Tank overflows and vents shall terminate in a downward direction, and shall be located and constructed to prevent entrance of contamination into the tank. A combined overflow and vent is permissible.

If a means is provided for determining the amount of water in the potable water tank, it shall be constructed to prevent the entrance of contamination into the tank.

6.2 DISTRIBUTION: All potable water distribution piping, tubing and fittings shall be of CORROSION-RESISTANT, NON-ABSORBENT AND NON-TOXIC MATERIAL. It shall not be subject to cracking or breaking under normally encountered temperature ranges and use. The potable water system shall not be cross-connected with any non-potable system. Overflows, vents, and drains from tanks or the distribution system shall not be connected directly to waste water lines or waste retention facilities. The entire distribution system shall be designed to allow for complete drainage. If protective covering for piping in the LOWER GALLEY is necessary, the covering shall be NON-ABSORBENT and EASILY CLEANABLE.

Water pressure may be maintained by gravity, compressed air or other non-toxic gases, or electric pump. When compressed air is used, a filter shall be installed in the air supply line. The potable water pump shall be used for no other purpose. Delivery of potable water to sinks, wash basins, and other facilities shall be through an air gap equivalent to twice the effective diameter of the inlet line but in no case less than one inch above the overflow rim of the fixture. Where an air gap is impractical, a properly installed ACCEPTABLE backflow preventer (vacuum breaker) shall be provided. A direct connection of the potable water system to a coffee making or ice making unit is ACCEPTABLE.

If aerators or strainers are used on water outlets, they shall be constructed or CORROSION-RESISTANT, EASILY CLEANABLE material and be EASILY REMOVABLE. Potable water system shall be properly cleaned, disinfected and flushed before being placed in service.

6.3 FILTERS: Filtration of potable water from approved sources is not necessary from a public health standpoint. If used, filters shall comply with the Food Additive Regulations of the Federal Food, Drug, and Cosmetic Act and shall be of the replaceable type. They shall not degrade the quality of the water. Filters and any other such device shall meet the applicable Environmental Protection Agency's requirements under authorities such as the Safe Drinking Water Act and Federal Insecticide, Fungicide and Rodenticide Act.

6.4 WATER HEATERS: Hot water heaters shall be supplied directly from a potable water system. The accumulation tank and heating elements shall be constructed of CORROSION-RESISTANT, NON-TOXIC material. The insulated casing for the hot water heating system shall be constructed to preclude the accumulation of soil and debris

6.5 WATER COOLERS: Water coolers shall be constructed to prevent contamination of the potable water supply. All surfaces in contact with potable water shall be constructed of CORROSION-RESISTANT, NON-TOXIC MATERIAL. A NON-TOXIC coolant shall be used.

6.6 DRINKING WATER STATIONS: Drinking water stations shall be constructed of EASILY CLEANABLE and CORROSION-RESISTANT MATERIAL. All corners subject to splash shall have a radius of at least 1/8 inch. Fountain orifices shall be of the angle-jet type with a guard designed to prevent mouth contact with the outlet. The outlet shall terminate at least an inch above the highest surrounding flood level rim. The drain strainer shall be READILY REMOVABLE. Aerators on faucet type outlet shall be READILY REMOVABLE. Cup dispensers shall be designed as outlined under Item 4.7.
