Under DOT Regulations

To the uninitiated, it would seem that all materials offered for transportation are considered hazardous. Obviously, this is not the case, since not all materials transported pose an unreasonable risk to health, safety and property, the basic criteria for regulating a material for transportation. Only liiose materials classified as hazardous under the Department of Transportation criteria are regulated and the degree of restriction which the regulation imposes depends on the kind of hazard or hazards for which the product is classified. 

A hazardous material is a material listed by DOT in the Hazardous Materials Table ( 172.101) by technical name, or, if not listed by technical name, a material that meets the specific criteria of a hazard class. A plus sign (+) on Column I of the Hazardous Materials Table fixes the hazard class and proper shipping name for that material without regard as to whether that material meets the definition of that hazard class. If petitioned, an alternate hazard class, in that case, may be authorized by the Associate Director, Office of Hazardous Materials Regulation, MTB ( 172.101(b)(l)). If a material listed by technical name on the Hazardous Materials Table meets the definition of a hazard class other than the class shown in association with the technical name, the material must be classified in accordance with the appropriate hazard class. It must then be described by the shipping name that best describes the material listed in association with the correct hazard classification. If the 

At present, DOT regulates as hazardous materials those which meet the criteria of one or more of the following hazard classes.

Because of thek flash pokits, nitroparaftins are classified as flammable Hquids under DOT regulations (ha2ard class 3, PG III). Nitromethane and nitroethane tires can be extinguished with water, CO2, foam, or class ABC dry chemical extinguishers. Nitroparaftins should not be exposed to dry caustic soda, lye, or similar alkaline materials. 

Technical 48% and 62% acids are colorless to light yellow Hquids available in dmms, 15,140-L tank trailers, and 37,850-L tank cars. They are classified under DOT regulations as corrosive materials. Anhydrous hydrogen bromide is available in cylinders, under its vapor pressure of approximately 2.4 MPa (350 psi) at 25°C. It is classified as a nonflammable gas. 

The time-weighted, 8-h average limit for exposure to bromine pentafluoride is 0.1 ppm (67). Materials of constmction suitable for use with the bromine fluorides include nickel. Monel metal, or Teflon. For shipping, bromine trifluoride and pentafluoride are classified as oxidizers under DOT regulations. The trifluoride also requires a poison label. 

Bromates represent a potential fire and explosion hazard if heated, subjected to shock, or acidified. They should not be allowed to contact reactive organic matter, including paper and wood. Industrial quantities are packed in fiber dmms with polyethylene liners or in metal dmms. Laboratory quantities are supphed in glass bottles. For shipment, a yellow oxidizer label is required under DOT regulations. 

Benzyl chloride is classified by DOT as chemicals NOIBN, poisonous, corrosive and a hazardous substance (100 lbs-45.45 kg). Benzal chloride is classified as poisonous and a hazardous substance (5000 lbs-2270 kg). Benzotrichloride is classified under DOT regulation as a corrosive Hquid NOS and a hazardous substance (10 lbs-4.5 kg). The Freight Classification Chemical NOI appHes. It is shipped in lacquer-lined steel dmms and nickel-lined tank trailers. Benzal chloride is handled in a similar fashion. 

The flowchart on page 22 can be used to determine if and when a post-accident drug or alcohol test is required under DOT regulations. 

Next, note that random testing is required under DOT regulations, and you must follow those regulations when administering your program. 

Both the EPA and the Department of Transportation (DOT) have responsibdities related to transport of hazardous waste. AU EPA hazardous wastes are hazardous materials under DOT regulations. Both agencies participate in the manifest system. As discussed in Chapter 14, DOT regulations address quantities, packaging, labeling, routes, shipping papers, incident reports, and training. 

Under DOT regulations, boron trifluoride is also authorized for shipment in any other cylinders specified as appropriate for nonliquefied compressed gas (which includes cylinders meeting DOT specifications 3B, 3E, 4B, 4BA, and 4BW cylinders meeting specifications 3, 3C, 3D, 4, 4A, 4C, 7, 25, 26, 33, and 38 may also be continued in boron trifluoride service, but new construction is not authorized) [4]. Cylinders of the 3A and 3AA type used in boron trifluoride service must be requalified by hydrostatic retest every 5 years under present regulations. All other cylinders authorized for boron trifluoride must similarly be requalified by hydrostatic retest every 5 years, with the following exceptions DOT 4 cylinders require hydrostatic retest every 10 years and types 3C, 3E, 4C, and 7 require no periodic retest. 

Inhibited 1,3-butadiene may be shipped by motor vehicle under DOT regulations in cargo tanks meeting DOT specifications MC-330 or MC-331, and in portable tanks complying with DOT-51 specifications. The minimum design pressure required for these tanks is 100 psig (690 kPa). 

Is used in transporting hazardous material in an amount requiring placarding under DOT regulations. 

Acrylonitrile is transported by rail car, barge, and pipeline. Department of Transportation (DOT) regulations require labeling acrylonitrile as a flammable Hquid and poison. Transport is regulated under DOT 49 CFR 172.101. Bill of lading description is Acrylonitrile, Flammable Liquid, Poison B, UN 1093 RQ. ... 

Alkan olamines have high boiling points and under normal ambient conditions their vapor pressures are low. Only DMAMP (see Table 2) forms an azeotrope with water, which boils at 98.4°C and contains 25% by weight of DMAMP. According to current DOT regulations, AMP, AMP-95, DMAMP, DMAMP-80, AEPD, and AB are all classified as combustible Hquids. 

Truck cargo tanks (for dangerous materials) are built under Part 173 and Siibpart J of Part 178, DOT regulations. This includes Specifications MC-306, MC-307, MC-312, and MC-331. MC-331 is required for compressed gas. Siibpart J requires tanks for pressures aoove 345 kPa (50 Ibf/in ) in one case and 103 kPa (15 Ibf/in ) in another to be built according to the ASME Pressure Vessel Code. A particular issue of the code is specified. 

Under the Department of Transportation (DOT) regulations, a hazardous material is any substance or material, including a hazardous substance and hazardous waste that is capable of posing an unreasonable risk to health, safety, and property when transported in commerce. DOT thus has broad authority to regulate the transportation of hazardous materials that, by definition, include hazardous substances as well as hazardous wastes. 

Not specifically listed in 21 CFR for use in food applications. When discarded, the compound is not a hazardous waste, as defined by the Resource, Conservation and Recovery Act (RCRA), and it is also not considered hazardous under the Department of Transportation (DOT) regulations. It is, however, listed in the Toxic Substances Control Act (TSCA) Inventory. 

In this chapter, the classification of industrial products for transportation under present DOT regulations and disposal classifications under RCRA will be discussed. A brief discussion of pesticide classification under FIFRA is also presented. It must be kept in mind that regulations are a living set of rules which are frequently modified by amendments, deletions and new definitions. Thus, while an attempt has been made to present the subject of product classification in a manner that will be affected as little as possible by the process of regulatory change, this is clearly not entirely possible. The reader must be aware of this fact and of his responsibility for keeping abreast of any new developments in this field. 

For the purpose of the DOT regulation, Flammable solid is any solid material, other than one classed as an explosive, which under conditions normally incident to transportation is liable to cause fires through friction, retained heat from manufacturing or processing, or which can be ignited readily and persistently as to create a serious transportation hazard. Included in this class are spontaneously combustible and water-reactive materials. (49CFR 173.150)... 

Hazardous waste, for the purpose of the DOT regulations, means any material that is subject to the hazardous waste manifest requirements of the EPA specified in 40 C.F.R. Part 262 or would be subject to these requirements absent an interim authorization to a state under 40 C.F.R. Part 123, Subpart F.
