Department of Transportation

Materials are classified for transportation using nine different categories  

Safety, health, and environment training includes initial and continuous training and the employment of safety systems that are carefully integrated into everyday operation. Some of these systems include permits, personal protective equipment, firefighting, hazard communication, HAZWOPER, and process safety management. 

OSH A and the EPA developed the process safety management (PSM) standard to prevent the catastrophic release of toxic, hazardous, or flammable materials that could lead to a fire, explosion, or asphyxiation. Several critical elements of the PSM standard include employee training, operations procedures, process safety, employee participation, and hot work. 

A fundamental principle of the chemical hazard communication (HAZCOM) program is that informed people are less likely to be injured by chemicals and chemical processes than uninformed people. A chemical hazard communication program is composed of both information and training. 

The types of permits used in the chemical processing industry include cold work permits, hot work permits, opening/blinding permits, permits to enter, unplugging permits, energy isolation procedures, and lock-out, tag-out procedures. 

In addition to statistics developed for USTs, in 1984 the EPA Office of Technology Assessment also reported that 16,000 spills occur annually during transport, while the DOT reported that of the 4112 accidents that occurred between 1968 and 1981, 1372 were associated with corrosion and 1101 with pipeline ruptures. Prior to the DOT regulating transport of liquids by pipeline in 1971,308 interstate pipeline accidents were documented resulting in a loss of about 245,000 barrels of liquid. Increasing DOT involvement may have been the reason for a decline in incidents to 275 in 1980, and 198 in 1981.

Polyacrylamide powders are typically shipped in moisture-resistant bags or fiber packs. Emulsion and solution polymers are sold in dmms, tote bins, tank tmcks, and tank cars. The transportation of dry and solution products is not regulated in the United States by the Department of Transportation, but emulsions require a DOT NA 1693 label. 

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. ... 

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. 

Shipment of hydrazine solutions is regulated in the United States by the Department of Transportation (DOT) which classifies all aqueous solutions between 64.4 and 37% N2H4 as "Corrosive" materials with a subsidiary risk of "Poison". Hydrazine has been identified by both the Environmental Protection Agency and the DOT as a hazardous material and has been assigned a reportable quantity (RQ) of 0.450 kg (1 lb) if spilled. Dmms for the shipment of these solutions must bear both the DOT specification "Corrosive" and "Poison" labels in association with the markings "RQ Hydrazine Aqueous Solution UN 2030." Aqueous solutions of 37% concentration or less are a hazard Class 6.1, UN 3293, Packing Group III and require "Keep Away From Food" placards and labels.

AH Department of Transportation (DOT), Environmental Protection Agency (EPA), and Occupational Safety and Health Act (OSHA) rules and regulations should be reviewed prior to handling hydrochloric acid and all the regulations must be followed. AH employees handling HCl must be trained to ensure that they are familiar with the appropriate materials safety data sheets and appHcable regulations. 

The Department of Transportation classifies HCl as a corrosive material and requires that it be transported in DOT-approved deHvery vessels. Tank cars must conform to 103B, 103B-W, or DOT 111A60W5 specifications. Tank trailers must conform to DOT MC-310, MC-311, MC-312, or DOT-412 specifications with display of a corrosive placard on both sides, front, and rear of the tank. The United Nations identification number for muriatic acid is UN1789, which must appear on aH shipping papers and placards. 

Concentrations over 8 wt % are classified as corrosive Hquids by the Department of Transportation (DOT). The Bureau of Explosives regulation (132) classifies all solutions containing 20 wt % and greater as oxidizers and corrosives. The product containers must have identifying labels (dmms) or placards (tank cars, tank trailers) indicating that the contents are an oxidizer and corrosive material, UN 2014 or UN 2015. Bills of lading must also be so identified. Tank cars and tank trailers are constmcted from high purity aluminum or 300 series stainless steel.

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.
