Placards transportation

Containers less than bulk must bear the red diamond-shaped "FLAMMABLE LIQUID" label. Bulk containers must display the red "FLAMMABLE" placard in association with the UN1090 identification. Fire is the main ha2ard in emergencies resulting from spills. Some manufacturers provide transportation emergency response information. A listing of properties and ha2ard response information for acetone is pubHshed by the U.S.

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. 

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. 

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. 

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...

Precautions to be taken in transportation Motor vehicles will be placarded regardless of quantity. Drivers will be given full information regarding shipment and conditions in case of an emergency. AR 50-6 deals specifically with the shipment of chemical agents. Shipment of agents will be escorted in accordance with AR 740-32. 

The categories of liquids are further subdivided into classes according to the flash point plus the boiling point of certain liquids. These divisions are summarized in Table 8, which shows that flammable liquids fall into Class 1, and combustible liquids into Classes 2 and 3. The products that are at the low end (100°F) of the Class 2 combustible-liquid group might be thought of as borderline cases. These could act very much like flammable liquids if atmospheric temperatures were in die same range. It is not a common industry practice to identify either stationary or portable (mobile) liquid containers by the class of liquid it contains. The usual practice is to label either "flammable" or "combustible" and include the required U.S. Department of Transportation placard. 

The Dept of Transportation has combined the shipping regulations which used to be separately administered by the US Coast Guard (Title 46, CFR Part 146) and the Federal Aviation Regulations (Title 14, CFR Part 103) (Ref 46). The new regulation provides for a uniform vehicle placarding and documentation system. They replace rail express criteria with a hazard assessment for aircraft operation, and uniform criteria for all shipping modes have been established. The list of hazardous materials has been completely revised and improved directions for their use have been included. The use of prescribed colors for labels is now mandatory (Ref 46)... 

Placard and label requirements for interstate shipment were changed by the U. S. Department of Transportation effective January 3, 1977 (3). 

The ID number (ID No ) for a material m transport may be displayed on placards, or on orange panels on tank trucks. Check the sides of the transport vehicle if the lO number is not displayed on the ends of the venicle or tank / ... 

Transport operation [training of drivers, supervision, emergency procedures, loading and unloading, placarding of vehicles]. 

Only two chemical groupings need to be indicated for the conqionents conqirising the most significant risk. This classification is an interim classification until an application is made to the European Union for the inclusion of fast pyrolysis liquid on the dangerous goods list. This classification should be used on all labels and for all sizes of shipments, in particular on the transportation documents and the MSDS. For tank containers, and bulk shipments, additional placarding is required and this is discussed below. 

Large sanqjles need to be transported in larger containers or tanks. Containers are specifically defined in the ADR regulations (2), The additional requirement for tank/containers is the use of a placard on road containers, displayed the appropriate UN code of 1993 on the bottom and 33X on the top [see next section]. Containers and tanks will be the preferred method with time for larger quantities for land transport. Again, acid resistant containers and tanks are required. 

More detailed information may also be provided to those exposed to hazardous chemicals. In the workplace, for example, material safety data sheets (MSDSs) may be available. In the transport sector, a document such as the North American Emergency Response Guidebook may supplement the information on placards or markings. The details on these information documents vary from system to system for the same chemical. 

The needs of the intended target audience influence what label components are used. In transport , for example, the label, placard, and transport documents are all used. In the workplace , the label is one element of a multicomponent system of chemical hazard communication, the other elements being the MSDS and training. In communicating the potential hazard of consumer products , the label plays the major role in providing the user with information about all the potential health, environmental, and physical hazards of the product and advice on using the product safely.
