Material transport container handling

Feedstocks. Feedstocks are viscous aromatic hydrocarbons consisting of branched polynuclear aromatics with smaller quantities of paraffins and unsaturates. Preferred feedstocks are high in aromaticity, free of coke and other gritty materials, and contain low concentrations of asphaltenes, sulfur, and alkah metals. Other limitations are the quantities available on a long-term basis, uniformity, ease of transportation, and cost. The abiUty to handle such oils in tanks, pumps, transfer lines, and spray nozzles are also primary requirements. 

Materials—which include chemicals, process equipment, transport containers, protective equipment, and replacement parts—need to conform to quality (ESH/PSM) standards and specifications before being placed in use. Different materials will need varying levels of test and/or inspection as well as controls on their storage and handling. 

Test and control article handling procedures are addressed. Procedures need to be established for a system for the handling of the test and control articles to ensure that proper handling and storage are utilized the materials are allocated so that there is no possibility of contamination, deterioration, or damage. At all times, identification of the contents must be maintained throughout the distribution process and all actions are documented. Identification of the contents of a container helps to ensure that the material will be used properly. It is also prudent to label temporary or transport containers to avoid mix-ups.

Transportation of waste between laboratories (satellite accumulation areas) and the central accumulation area also requires specific attention to safety. Materials transported must be held within appropriate and clearly labeled containers. There must be provision for spill control in case of an accident during transportation and handling. For larger institutions, it is advisable to have some kind of internal tracking system to follow the movement of waste. If public roads are used during the transportation process, additional Department of Transportation (DOT) regulations may apply. 

Labeling Serious errors in the transport and handling of hazardous materials could occur when people involved do not know what is in containers. DOT has many regulations regarding labeling of particular materials. Typically, a label indicates which material is inside a container. Labels also... 

The plutonium canister assay system (PCAS) determines the content of plutonium in MOX and pure oxide powders in cans contained in a specific transport container (four cans per canister) (Menlove et al. 1986). The system can be integrated into an operator s material handling system and continuous measurement cycles are performed, which are evaluated at the end of a given collection period. Thereby, continuous verification of the flow of canisters can be performed without inspectorate intervention. For inventory verification, an inspector provides an electronic list of canisters to be verified and the operator transfers the selected... 

A flexible print material, which can be developed by a water-based developer, has been commercialized. Flexible print material is a gel that contains a photopolymerizable monomer or oligomer. Upon photocuring, the uncrosslinked portion is removed by a solvent and a print plate is prepared. From both the safety and the environmental standpoints, the trend is to use a water-based developer. To improve development capability, a microgel with a hydrophilic surface is used [26]. The solid property, transportability, and handling are improved as a result of the addition of the microgel. 

Caustic soda is classified as a corrosive material by the DOT and DOT regulations and specifications must be followed for handling, labeling, and transportation in containers. Warning labels are recommended for containers of caustic soda solutions and anhydrous caustic soda by the MCA (79). The DOT identification number is UN1824 for 50 or 73% Hquid, and UN1823 for anhydrous caustic. 

Corrugated and Solid Fiber Boxes. Cormgated and soHd fiber boxes are used primarily as shipping containers. Both types of containers are made from several layers of paperboard, normally referred to as combined board. Container board is the material from which the combined board is fabricated. Although both types of boxes serve the same general purpose, eg, in the handling, storage, and transportation of commodities, they differ markedly in thein manufacture, stmcture, and performance. 

An international non-profit educational association representing transporters and container manufacturers of hazardous materials, substances, and wastes concerned with the safe handling of these substances. Provides regulator assistance and advice for establishing hazardous materials compliance and safety programs.
