warnings. The primary color warning is the color assigned to identify the classification of the material according to its primary hazard from a safety standpoint. These colors appear as the main body, top, or band colors on compressed gas cylinders. A secondary color warning is the color assigned as a warning of a secondary hazard held by a material. This means that the material may have another type of secondary hazard that is distinctly different from that shown by its primary color warning. These colors appear as band colors on compressed gas cylinders. The following sections list the colors used as both primary and secondary warnings. Yellow identifies flammable or combustible materials. Brown identifies toxic and poisonous materials. Blue identifies anesthetics and harmful materials. These are materials that produce anesthetic vapors and liquid chemicals and compounds hazardous to life and property. However, these materials do not normally produce dangerous quantities of fumes or vapors. Green identifies oxidizing materials. These are all materials that readily furnish oxygen for combustion and react explosively when they come in contact with hot material. Gray identifies physically dangerous materials. These are materials, safe in themselves, that are asphyxiating in confined areas. These also are materials handled in a dangerous physical state of pressure or temperature. Red identifies fire protection materials. Black identifies a combination of oxygen and other gases. Buff (tan) identifies industrial gases. Orange identifies refrigerants. In addition to its basic colors, each cylinder marking may include a combination of colored stripes to identify a particular compressed gas. Refer to chapter 2 of NAVSUP P-485 or to P-567 for a listing of the different types of gases and the color markings used on compressed gas cylinders. Aerosol products are liquids, solutions, or powders contained in pressurized dispensers. The dispensers have release valves to control the discharge amount of the product. Aerosol containers are commonly used for the disposal of paints, enamels, lacquers, insecticides, silicones, and rust preventives. The aerosol propellant may be low-boiling, halogenated hydrocarbons or other hydrocarbons such as liquid propane or isobutane. Aerosol cylinders will burst if exposed to heat sources more than 120°F. Aerosol cans are prone to leakage when dented or hit against hard objects. Aerosol propellants are extremely flammable and, in enough concentration, can be anesthetic or asphyxiating. Therefore, aerosol products should be stowed in the flammable liquids storeroom or in cabinets away from oxidizing materials. The space should have mechanical ventilation, when necessary, to remove accumulated vapors. RADIOACTIVE MATERIAL.— Radioactive materials are assigned an SMCC of R or X if radioactive and magnetic. These materials have the United States Nuclear Regulatory Commission (USNRC) radiation symbol label. This label must be in good condition and remain with the material at all times. Any area used for storing radioactive material must have the standard radiation symbol and the words C A U T I ON RADIOACTIVE MATERIAL conspicuously posted. Report any suspected radiation hazard promptly to the radiological safety officer and a representative of the medical department. Miscellaneous Material This section lists those other items requiring special handling. CLASSIFIED MATERIAL.— Stowage and handling of classified material must be in accordance with the Department of the Navy Supplement to the DOD Information Security Program Regulation, OPNAVINST 5510.1. DELICATE INSTRUMENTS.— Delicate instru- ments are usually expensive and easily damaged. These materials require especially careful handling and protective stowage. You must keep the instruments in a dry atmosphere, away from magnetron tubes or magnetic devices. When possible, the storeroom temperature should be 70°F or below. DRUMMED PRODUCTS.— Drummed products on board ships may contain flammable liquids or nonflammable material. Stow drums on end with the bung end on top. Each drum must have adequate identification of its contents legibly indicated on the side of the drum. If stowed on the weather deck cover the drums with a tarpaulin (when practical). Drummed products must be inspected at least weekly to make sure the bungs are tight and there are no leaks or corrosion. SHELF-LIFE MATERIAL.— Shelf-life material requires inspection upon receipt to ensure adequate 6-9
