Drums and Portable Containers
Hazardous materials may be shipped in a variety of containers, including bottles, bags, drums, boxes, and portable tanks. You might encounter containers of hazardous materials inside a shipping container, box truck, rail car, or warehouse.
Generally, more strongly reinforced and durable containers are more likely to contain hazardous materials. To identify the container's contents, check for attached labels or tags and for printed documentation.

To identify the contents of a container, check for:
- Attached label or tag.听Look on each container for markings or on an attached label or tag showing (a) the shipping name of the substance in the container and (b) the UN/NA number for the hazardous material it contains.
- Hazard label.听Any hazmat container also should display a diamond-shaped label depicting the enclosed material's hazards.
- Shipping papers or cargo manifest. Look for these documents for the vessel or vehicle carrying the portable container; the documents should list the UN/NA number and name for each hazardous material. (Where can I find shipping papers or cargo manifests?)听On shipping papers or cargo manifests , look for the听 UN/NA number and shipping name for each hazardous material. Below is an example of how these identifiers might be shown on a shipping paper. The shipping papers also show each substance's hazard class or division number (shown below after听the shipping name), which indicates its hazards.
Once you have听found identifiers for the chemical, you can look up its datasheet in CAMEO 365bet娱乐.

Portable Tanks and Bulk TotesPortable Tanks and Bulk Totes
- May contain flammable , combustible , toxic , or corrosive liquids, as well as non-hazardous materials.
- Capacities and dimensions vary. Some portable tanks hold up to 550 gallons; a common tote capacity is 300 gallons.
- Typically transported on flatbed trucks, box trailers, and rail flatcars.
- May be composed of ABS plastic, steel, aluminum, or other materials.
Drums contain a wide variety of solid and unpressurized liquid hazardous materials. The construction material of a drum is a clue to its contents:
- Unlined听fiberboard: dry granular materials (e.g., fertilizer, sawdust, and grain)
- Plastic-lined fiberboard: wet materials (e.g., foods and slurries)
- Plastic: corrosive materials (e.g., sodium hydroxide and acids), combustible materials, some foods
- Steel: flammable and combustible materials (e.g., alcohols and fuel oils), mild corrosives, food liquids
- Stainless steel: strong corrosives (e.g., oleum )
- Aluminum: pesticides, materials that react with steel and cannot be shipped in plastic containers
Drums vary from 1鈥�95 gallons in capacity; a typical capacity is 55 gallons.
- Cylinders transport and store many different hazardous pressurized gases (e.g., chlorine and hydrogen). Special insulated cylinders are used to carry cryogenic gases.
- Cylinders range in capacity from about 1 pound to thousands of pounds, and internal pressures range from about 200 to 5,000 psi .
- Most cylinders have pressure relief valves that allow gas to escape if the cylinder is overpressurized or heated in a fire, preventing dangerous pressure buildup.
- Bottles鈥攚hich can be made of glass, metal, or plastic鈥攃an contain hazardous liquids.
- Bottles range in capacity from about an ounce to a gallon.
- Bottles are often transported packed within cardboard boxes.
Cardboard BoxesCardboard Boxes
- Cardboard boxes can carry hazardous materials (such as pesticides and household products) as well as hazardous liquids packed in bottles.
- Cardboard boxes lined in plastic may carry hazardous liquids.
- Bags鈥攚hich can be paper, plastic, or fiber (reinforced or not)鈥攁re often used as containers for chemicals and pesticides, as well as food.
- Very large reinforced polypropylene bags (called "supersacks") may carry hazardous solids.
