Viayl fluoride is flammable ia air between the limits of 2.6 and 22% by volume. Minimum ignition temperature for VF and air mixtures is 400°C. A small amount, <0.2%, of terpenes is added to VF to prevent spontaneous polymerization. The U.S. Department of Transportation has classified the inhibited VF as a flammable gas. 

U.S. Department of Transportation classification flammable Hquid, hazard label 3.3 DOT/UN /Na shipping number 2521, flammable Hquid. Transport by sea IMDG-code class 3.3, p. 3333, emergency sheet 3—06. Transport by rail and road RID/ADR class 3 Rn 301-31c. 

Finish removers are appHed by bmshing, spraying, troweling, flowing, or soaking. Removal is by water rinse, wipe and let dry, or solvent rinse. Removers may be neutral, basic, or acidic. The viscosity can vary from water thin, to a thick spray-on, to a paste trowel-on remover. The hazard classification, such as flammable or corrosive, is assigned by the U.S. Department of Transportation (DOT) for the hazardous materials contained in the remover.

Transportation of Chemicals. Feed materials and finished products are frequendy transported by tank tmck and railroad tank cars. Design, constmction, and movement of these vehicles is regulated by the U.S. Department of Transportation (DOT) (97). The DOT regulations require placarding of material-transport vehicles to alert the pubHc and emergency personnel to the nature of their contents.

Handling of Amines. Regulations governing the safe handling and shipping of amines in interstate commerce are given in U.S. Department of Transportation pubHcations (71). Specific information on the safe handling and hazards associated with a particular amine can be found in the Material Safety Data Sheet for that material. For further information on the safety of industrial material see also references 72 and 73. 

Propylene oxide is classified as a flammable Hquid and ha2ardous substance in the U.S. Department of Transportation (DOT) Ha2ardous Materials Table. The DOT shipping requirement is Propylene Oxide, 3, UN 1280, PG 1. The red flammable Hquid label and red flammable placard are required on aH... 

Shipment Methods and Packaging. Pyridine (1) and pyridine compounds can be shipped in bulk containers such as tank cars, rail cars, and super-sacks, or in smaller containers like fiber or steel dmms. The appropriate U.S. Department of Transportation (DOT) requirements for labeling are given in Table 4. Certain temperature-sensitive pyridines, such as 2-vinylpyridine (23) and 4-vinylpyridine are shipped cold (<—10°C) to inhibit polymerisation. Piperidine (18) and certain piperidine salts are regulated within the United States by the Dmg Enforcement Agency (DEA) (77). Pyridines subject to facile oxidation, like those containing aldehyde and carbinol functionaUty, can be shipped under an inert atmosphere. 

The NRC has developed special procedures for the handling, transportation, and storage of nuclear fuel because radioactivity can be a health hazard if not properly shielded. Spent fuel is typically transported by rail or tmck in heavily shielded (Type B), sealed, thick metal shipping containers designed to withstand possible accidents, such as derailments or coHisions, which may occur during transport. The NRC certifies that each shipping container meets federal requirements. The U.S. Department of Transportation sets the rules for transportation. 

Hickman, WiUiams and Company has filed an appHcation for exemption with the U.S. Department of Transportation Administrator for Ha2ardous Materials Safety regarding 50 and 75% ferrosiUcon, and magnesium ferrosiUcon. At this writing (ca 1996), a decision on this appHcation is stiU pending. 

Transportation and Disposal. Only highly alkaline forms of soluble sihcates are regulated by the U.S. Department of Transportation (DOT) as hazardous materials for transportation. When discarded, these ate classified as hazardous waste under the Resource Conservation and Recovery Act (RCRA). Typical members of this class are sodium sihcate solutions having sihca-to-alkah ratios of less than 1.6 and sodium sihcate powders with ratios of less than 1.0. In the recommended treatment and disposal method, the soluble sihcates are neutralized with aqueous acid (6 Af or equivalent), and the resulting sihca gel is disposed of according to local, state, and federal regulations. The neutral hquid, a salt solution, can be flushed iato sewer systems (86). 

Many silver compounds are unstable to light, and are thus shipped ia brown glass or opaque plastic bottles. Silver compounds that are oxidants, eg, silver nitrate and iodate, must be so identified according to U.S. Department of Transportation (DOT) regulations. Compounds such as silver cyanide, which is toxic owiag to its cyanide content, must carry a poison label. However, most silver compounds are essentially nontoxic. 

The LD q for sodium bromide taken orally by rats is 3.5 g/kg body weight, and the TD q orally in rats is 720 mg/kg (8). RTECS Hsts data on reproductive effects in male and female rats. Sodium bromide is Hsted in the TSCA Inventory, the Canadian Domestic Substances Hst (DSL), the European Inventory of Existing Commercial Chemical Substances (EINECS), the Japanese Existing and New Chemical Substances (ENCS), and the Korean Existing Chemicals Hst (ECL). It is not regulated by the U.S. Department of Transportation. 

Chloroformates are shipped in nonretumable 208-L (55-gal) polyethylene dmms with carbon steel overpacks or high density polyethylene dmms. Eor bulk shipments, insulated stainless-steel tank containers and tmcks provide secure protection. Tank tmck and rail car quantities are shipped using equipment dedicated for these types of products. Materials such as isopropyl chloroformate, benzyl chloroformate, and j -butyl chloroformate that require refrigeration are precooled when shipped in bulk containers. Bulk shipments that are precooled must proceed to the destination without layover. Dmm shipments of IPCE, BCE, and SBCE must be shipped in refrigerated containers. Many of the chloroformates are only shipped in tmck load shipments. The U.S. Department of Transportation (DOT) Hazardous Materials Regulations control the shipments of chloroformates, as described in Table 3. 

The carbonates should be plainly labeled and stored in cool, dry areas away from sources of ignition. The U.S. Department of Transportation (DOT) Hazardous Materials Regulations control the shipment of carbonates as described in Table 8. 

Commercial ethyl alcohol is shipped in railroad tank cars, tank tmcks, 208-L (55-gal) and 19-L (5-gal) dmms, and in smaller glass or metal containers having capacities of 0.473 L (one pint), 0.946 L (one quart), 3.785 L (one U.S. gal), or 4.545 L (one Imperial gal). The 208-L dmms may be of the unlined iron type. If a guarantee of more meticulous quaUty is desired, the dmms may be lined with phenoHc resin. AH containers, of course, must comply with the specifications of the U.S. Department of Transportation. Both 190 proof and 200 proof ethyl alcohol are considered red label (flammable) materials by the DOT, as both have flash points below 37.8°C by the Tag closed-cup method.
