(a) maximum capacity greater than 119 gallons as a receptacle for a liquid, (b) maximum net mass greater than 882 pounds or a maximum capacity greater than 119 gallons as a recepacle for a solid, or (c) water capacity greater than 1,000 pounds as a receptacle for a gas.
Cryogenic liquid tank car
- insulated, placed under a vacuum, tank inside of a tank, no capacity, no visible fittings, cabinet underneath on middle of container, dished ends. -Contains: liquid argon, ethylene, hydrogen, nitrogen, and oxygen; Hazard Class 2.2 - 25psi or less - (-130) degree Fahrenheit
Noded Spheroid
-Capacity: vary with construction design -0.5-15 psig -Hazard class: 2,3 -Examples: LPG, methane, propane, and other light gases. It may also contain certain flammable liquids such as gasoline and crude oil
Excepted
-Extremely low levels of radiation -packaging and transport req should be of reasonable strength due to limited haz -packages not identified as such by markings or shipping papers
Pipeline markers
-Product -Owner -Emergency telephone number -signal word "danger" etc -be aware that markers don't always indicate location, don't always follow a straight line between the markers, and look for pipeline marker where it intersects with a street or railroads
Type B (Radioactive container)
-Protects against high radiation to include spent nuclelar fuel -withstand 30 ft drop -Size: small hand held to 125 ton shielded steel casks -withstand 30 ft drop on weakest point -puncture dropped 40 inches into a 6 in diameter steel rod that is 8 in high -withstand 1475 F for 30min -drop of 1100lbs mass, 30 ft onto the package and immersion under water 50ft
Type C (Radioactive container)
-Rarely used -most hazardous amounts of radiation -if packaging is released or shielding fails life threatening conditions could exist

Cryogenic Intermodal Tanks
Also known as IMO-7 4,500 to 5,000 gallons 25 psi or less -130
Dry bulk railroad`
Also known as pneumatically off-loaded hopper car • May use air pressure to off-load—product is "blown" out of the bottom discharges • Need to ground and bond when transferring product. Movement of product through hoses causes a buildup of static electricity Contents: • Ammonium nitrate fertilizer • Cement • Plastic pellets • Caustic soda in powdered form • Grain
Vessel Cargo Carrier
Barges, cargo vessel, tanker vessel
drums
Barrel-like containers used to store a wide variety of substances. 55 gal is common
Flexible Intermediate Bulk Container (FIBC)
Bulk sack, bulk bag. supersack, big bags, tote bags
Intermodal containers
Can switch between ship, rail or truck while staying in the same container
Reporting Marks
Combination of letters and numbers stenciled on rail tank cars that may be used to get information about the car's contents from the railroad or the shipper
