1910.1201(a) Any employer who receives a package of hazardous material which is required to be marked, labeled or placarded in accordance with the U. Transporting hazardous materials that meet DOT requirements are marked with warning placards.
Each placard includes the color, symbol, and name of the class into which the hazard falls. Included with the DOT placards are United Nations identification numbers specific to each transported substance. The numbers are displayed inside the placard or in an orange rectangle immediately below the placard. Division 4.2 (Spontaneously Combustible Material) means a pyrophoric material or a self-heating material.
Division 4.3 (Dangerous when wet material) means a material that, by contact with water, is liable to become spontaneously flammable or to give off flammable or toxic gas at a rate greater than 1 liter per kilogram of the material, per hour. An OXIDIZER (Division 5.1) is a substance that yields oxygen readily to stimulate the combustion of other materials. Division 6.1 Toxic Substances includes toxic substances, poisons, and irritating materials.
Division 6.2 Infectious Substance It means a material known or reasonably expected to contain a pathogen. For POISON (PGl or PGII, other than inhalation hazard) and POISON (PGIII), placard 454 kg (1,001 lbs) or more.


Radioactive materials contain charged particles (ions) and have an specific activity greater than 0.002 micro curies per gram. A material which presents a hazard during transportation but which does not meet the definition of any other hazard class.
A freight container, unit load device, transport vehicle, or rail car which contains non-bulk packages with two or more categories of hazardous materials that require different placards may be placarded with DANGEROUS placards instead of the specific placards.
Temporary placards for vehicles were signs are changed often, easy to apply and easy to remove. Transporting certain goods across long distances presents potential safety hazards, thus appropriately labeling, or placarding, the product’s shipping containers serves as a protection.
The CFR also offers general guidelines for how a container should be placarded before leaving for transport. The Pipeline and Hazardous Material Safety Administration Office of Hazardous Materials Safety website notes that hazardous materials fall into one of nine categories, based on the type of danger they present. The USDOT holds the shipper responsible for making certain that the placards remain in place during shipment. A variety of symbols are used to indicate combustion, radiation, oxidizers, compressed gas, destruction of materials and skin by corrosives, an explosion, or skull and cross bones to indicate poisons. Lithium alkyls are an example of a pyrophoric material (a chemical which spontaneously ignites when exposed to air) in Division 4.2.
Toxic substance is a poisonous material, other than a gas, that is known to be so toxic to humans as to cause death, injury or harm to human health if swallowed, inhaled or brought into contact with skin.


A bulk packaging containing a Class 9 material must be marked with the appropriate ID number displayed on a Class 9 placard, an orange panel, or a white square-on-point display. However, when 1,000 kg (2,205 lbs) or more of one category of material is loaded at one loading facility, the specific placard must be applied. Accordingly, each freight container, unit load device, transport vehicle or rail car containing any amount of hazardous material must have a placard on each side and end. The legal responsibility for providing placards that properly identify hazardous materials lies with the producer or packager of the materials. The four placards stay in place from the time the shipment leaves its point of origin until the crew unloads it at its destination. Examples of specific placard designations include Explosives, Poison Gas, Dangerous When Wet, Organic Peroxide, Poison Inhalation Hazard and Radioactive. Permissive placarding includes signage designating a hazardous substance in transport, while prohibited placarding disallows signage which, by its color or shape, could be confused with a federally-designated placard.
