Compressed air is often used to empty tank trucks and cars. Plastic pellets are often blown out of tank trucks. When the tank is empty, the driver vents the tank and then looks through the manhole to check that the tank is empty. One day a driver who was not regularly employed on this job started to open the manhole before releasing the pressure. When he had opened two out of five quick-release fastenings, the manhole blew open. The driver was blown off the tank top and killed. 

The burner and associated equipment must be wrapped up or otherwise protected against dirt and soot. The front doors are opened and plastic sheeting is attached to minimize the spread of soot. The tubes are brushed, and the soot and dirt are vacuumed away while brushing takes place. Some contractors have truck-mounted vacuum systems to increase efficiency and minimize post-boiler cleaning work. 

In 2002, the world production of polymers (not including synthetic libers and rubbers) was ca. 190 million metric tons. Of these, the combined production of poly(ethylene terephthalate), low- and high-density polyethyelene, polypropylene, poly(vinyl chloride), polystyrene, and polyurethane was 152.3 milhon metric tons [1]. These synthetic, petroleum-based polymers are used, inter alia, as engineering plastics, for packing, in the construction-, car-, truck- and food-industry. They are chemically very stable, and can be processed by injection molding, and by extrusion from the melt in a variety of forms. These attractive features, however, are associated with two main problems ... 

Polystyrene is used in furniture, packaging, appliances, automobiles, construction, radios, televisions, toys, houseware items, and luggage. Statistics on the states producing the largest number of plastic products are given in Table 2E4. This indicates that we can expect to have many customers and that most of these will be small companies. The main means for shipping will therefore be by truck and train, and many of these shipments will be small quantities. It therefore would be wise to locate as near as possible to customers. (The styrene can be obtained in large bulk shipments and over 95% is converted into a salable polystyrene.) Note that the... 

Dr. Mark s World War I exploits (including an escape from an enemy prisoner-of-war camp) read like a Hollywood film script. During World War II, he contributed to the Allied cause through development of plastic-coated tents, mildewproof fabrics, gasproof clothing, an amphibious truck, and the snow vehicle called the Weasel. ... 

Shipping and Storage. MSA is shipped in tank trucks and in plastic 55-gallon drums or smaller containers with polyethylene inserts. The freight classification is Alkyl Sulfonic Acid, Liquid 8 Corrosive Material, UN 2586, Chemical N01BN. 

Other sources have listed the automotive RIM market at approximately 41 Mi lbs. in 1982 (BOC) growing to nearly 95 Mi lbs. in 1987, while still another study reports 59 mm for automotive elastomers in 1982 -(Plastics Technology). This last figure of 59 Mi lbs. includes application in buses, trucks, and recreational vehicles. Table II gives data for industrial consumer products. The types of applications in these areas have been discussed previously (2) but include such markets as electronic cabinetry, recreational, shoes, agricultural and various appliances. 

At the peak of its operation in 1980, the mine had 900 employees. The orebody was mined by conventional open-pit, truck-and-shovel methods. A total of 400 million dry short tons (364 million metric tons) was removed, and processed for recovery of copper and molybdenum. An additional 600 million short tons (545 million metric tons) of overburden were excavated, resulting in an oval pit that was 7,900 feet (2,408 meters) long, 3,500 feet (1,067 meters) wide, with a bottom elevation 1,322 feet (403 meters) below sea level. The operation had two unique features Mill tailings were deposited below the ocean surface in Prince Rupert Inlet, and a plastic concrete seepage barrier, 4,000 feet (1,219 meters) long, 108 feet (33 meters) deep, but only 2.8 feet (0.86 meters) wide, was installed along the original shoreline of the inlet. 

Other than packaging, collectible items are automobile, light truck and large appliance shredded residue carpets wire and cable coverings and tailings— plastic containing streams recoverable from MSWs. 

Pillow tanks, constructed of polymers and heavy fabrics, are usually used to store oil recovered on land. These are placed on a solid platform so that rocks cannot puncture the tank when full. Pillow tanks are also sometimes used on the decks of barges and ships to hold oil recovered at sea. Oil recovered on land is often stored in stationary tanks built for other purposes, and in dump trucks and modular containers, lined with plastic. Recovered oil can also be temporarily stored in pits or berms lined with polymer sheets, although this open type of storage is not suitable for volatile oils. 

The 50% aqueous acrylamide is the preferred form because it eliminates the handling of solids and because its cost is lower. This is a result of the new manufacturing method put into effect in 1971. The aqueous form is applicable to nearly all the end uses of acrylamide when volume is taken into account. Aqueous acrylamide is shipped in tank trucks, rail cars, or dmms, but small samples can also be obtained. The solution should be kept in stainless steel or in tanks coated with plastic resin (phenolic, epoxy, or polypropylene). All containers, including tank trucks and rail cars, must be rinsed prior to disposal or return. When shipping costs are an important consideration, solid acrylamide may be the desired form. Acrylamide should be stored in a well ventilated area away from sunlight. The temperature should be under 30°C, and under these conditions no change of quality should be noticed for at least 3 months. Typical specifications for the 50% aqueous solution are shown in Table 5 and for the solid monomer in Table 6.
