MANUAL OF NAVAL PREVENTIVE MEDICINE

5-6.2 Steam

Steam used in contact with food and food-contact surfaces must be free from

any materials or additives other than those specified in 21 CFR 173.310.

Currently, shipboard steam contains additives which are not acceptable for

use with food and/or food contact surfaces.

5-6.3 Sewage

Ashore, all sewage wastes must be disposed through an approved community

sewage treatment plant or an individual sewage disposal system which is

sized, constructed, maintained and operated according to law. References

include Chapter 7, NAVMED P-5010; OPNAVINST 5090.1; and NSTM 593.

5-6.4 Equipment Connections

a. Warewashing machines, refrigerators, steam kettles, potato peelers,

and other similar equipment must not be directly connected to the

wastewater system without an air gap between the equipment and the

wastewater lines. Where permitted by law, a sink may have a direct

connection provided the drain line is properly trapped. Warewashing

machines may have direct connections between their waste outlets and the

floor drain when the connection is on the inlet side and immediately

adjacent to the floor drain trap, and the floor/deck drain is properly

trapped and vented.

b. Ice making machines will have an air gap as specified in section 5-

6.1(c) between the outlet and the drain's wastewater line.
