Other Miscellaneous Hazardous Materials

Ammonium nitrate fertilizers that are not classified as oxidizers are classified as miscellaneous hazardous materials. This type of fertilizer has other materials in the mixture, and there are controlled amounts of combustible materials. Mixtures of ammonium nitrate, nitrogen, and potash that are not more than 70% ammonium nitrate and do not have more than 0.4% combustible material are included as a miscellaneous hazardous material. Additionally, ammonium nitrate mixtures with nitrogen and potash, with not more than 45% ammonium nitrate, may have combustible material that is umestricted in quantity. The four-digit UN identification number for these mixtures of ammonium nitrate fertihzer is 2071. 

Box truck with over pack drum underneath, usually hauling hazardous waste. 

Solutions of formaldehyde, 30 to 50%, such as those used in preservatives, are listed as miscellaneous hazardous materials. These solutions are nonflammable, and the toxicity is below the requirements for a poison liquid. However, the material may still be carcinogenic. Formaldehyde solutions usually contain up to 15% methanol to retard polymerization. The four-digit UN identification number for nonflammable solutions is 2209. 

Batteries containing lithium are listed as miscellaneous hazardous materials. The storage batteries are composed of lithium, sulfur, selenium, tellurium, and chlorine. These batteries have four-digit UN identification numbers assigned depending on the use and composition of the battery. Lithium batteries contained in some kind of equipment have the four-digit number 3091. Batteries with liquid or solid cathodes, not in any kind of equipment, are given the number 3090. 

Titanium dioxide, TiOj, is a white powder and has the greatest hiding power of all white pigments. It is noncombustible however, it is a powder and, when suspended in air, may cause a dust explosion if an ignition source is present. It is not hsted in the DOT Hazardous Materials Table, and the DOT does not consider it hazardous in transportation. The primary uses are as a white pigment in paints, paper, rubber, and plastics, in cosmetics, welding rods, and in radioactive decontamination of the skin.

Miscellaneous hazardous materials in DOT/UN Class 9 are defined as a material which presents a hazard during transportation, but which does not meet the definition of any other hazard class. Other hazards might include anesthetic, noxious (harmful to health), elevated temperature, hazardous substance, hazardous waste, or marine pollutant. They may be encountered as solids of varying configurations, gases, and liquids. Examples include asbestos, dry ice, molten sulfur, and lithium batteries. These materials would be labeled and placarded with the Class 9 Miscellaneous Hazardous Materials placard, which is white with seven vertical black stripes on the top half. 

Also included in the Miscellaneous Hazardous Materials class is Other Regulated Materials ORM-D, Consumer Commodities. They are materials that present a limited hazard during transportation due to the form, quantity, and packaging. Some of these materials, if they were shipped in tank or box truck quantities, would fit into another hazard class. However, because the individual packaging quantities are so small, the DOT considers the hazard is limited and they are labeled ORM-... 

For the purposes of this subchapter, miscellaneous hazardous material (Class 9) means a material which presents a hazard during transportation but which does not meet the definition of any other hazard class. This class includes (a) Any material which has an anesthetic, noxious or other similar property which could cause extreme annoyance or discomfort to a flight crew member so as to prevent the correct performance of assigned duties or (b) Any material that meets the definition in Sec. 171.8 of this subchapter for an elevated temperature material, a hazardous substance, a hazardous waste, or a marine pollutant.
