of Hazardous Materials
U.S. DEPARTMENT OF TRANSPORTATION
TITLE 49 CFR PART 172.101
The DOT has broad authority to regulate hazardous materials that are
in transport, including the discretion to determine which materials
shall be classified as "hazardous". These materials are placed in one
of nine categories, based on their chemical and physical properties.
Based on the classification of the material, the DOT is also responsible
for determining the appropriate packaging materials for shipping or
transport. Finally, also based on the material classification, strict
guidelines are furnished for proper labeling/marking of packages of
hazardous materials offered for transport, and for placarding of transport

- Division 1.1 Explosives with a mass explosion hazard
- Division 1.2 Explosives with a projection hazard
- Division 1.3 Explosives with predominantly a fire hazard
- Division 1.4 Explosives with no significant blast hazard
- Division 1.5 Very insensitive explosives
- Division 1.6 Extremely insensitive explosive articles

- Division 6.1 Poisonous materials
- Division 6.2 Etiologic (infectious) materials
- Class 7: Radioactive materials
- Any material, or combination of materials, that spontaneously
gives off ionizing radiation. It has a specific activity greater
than 0.002 micro curies per gram.
- Class 8: Corrosives
- A material, liquid or solid, that causes visible destruction
or irreversible alteration to human skin or a liquid that has
a severe corrosion rate on steel or aluminum.
- Class 9: Miscellaneous
- A material which presents a hazard during transport, but which
is not included in any other hazard class (such as a hazardous
substance or a hazardous waste).
- ORM-D: Other regulated material
- A material which, although otherwise subjected to regulations,
presents a limited hazard during transportation due to its form,
quantity and packaging.
- * The words "poison" or "poisonous" are synonymous
with the word "toxic".

Hazard communication forms the backbone of emergency response, and
response begins with identification. The primary mission of DOT hazard
communication is to alert the public and transportation workers of the
presence of hazardous materials, and to insure that incompatible materials
are segregated when placed in the same transport vehicle, storage area
(or lab!). The distinctive DOT system of labeling and placarding provides
another visual clue for responders to a hazardous material incident.
Hazard markings, labels and placards are a common approach to warning
the public of hazards that may be encountered. The DOT uses labels,
defined as 4" x 4" colored diamond with warning words and graphics,
affixed to the outside of the shipping container or box. Labels are
required on the outside of the package regardless of the quantity shipped.
The DOT requires placards, a much larger version of the labels, to be
displayed on tank cars, cargo tanks, portable tanks and bulk packaging.
Requirements for placarding are dependent upon the identity and quantity
shipped. "Markings" are required to convey specific information about
the enclosed hazard and the person responsible.
[Back to top]
Placards are used to represent the hazard classes of materials contained
within freight containers, motor vehicles or train car. Labels communicate
the same hazards for smaller containers and packages offered for transport.
Examples of the placards and labels used for the various hazard classes
||This placard or label is used to designate explosive materials,
specifically Class 1.1, 1.2 and 1.3 explosives. Explosives that
belong to classes 1.4, 1.5 and 1.6 will have that specified, with
the class designation replacing the exploding ball. This placard
is required when transporting ANY quantity of a Class 1.1,
1.2 or 1.3 explosive, or over 1001 lbs of a Class 1.4 or 1.5 explosive.
|The placards and labels below are used to designate
compressed gases. Given the diverse chemical properties of compressed
gases, this class is subdivided into flammable gases (Class 2.1),
nonflammable gases or oxygen (Class 2.2) and poisonous gases (Class
||This placard is required when transporting over 1001 lbs of Class
2.1 or 2.2, or when transporting ANY quantity of poisonous
(Class 2.3) gas.
||Flammable liquids are identified by this placard / label. Certain
common flammable liquids have their own placards, where the name
of the material (such as gasoline and fuel oil) replaces the word
"FLAMMABLE". Also, materials that fit the definition of a combustible
material, have the word "COMBUSTIBLE" replacing the word "FLAMMABLE".
Required when transporting over 1001 lbs of flammable materials.
|The placards and labels below are used to indicate
cargo containing flammable solids (Class 4.1), materials that are
pyrophoric (i.e., ignite in the presence of oxygen) (Class 4.2),
and those that react adversely when exposed to water or humidity.
(Class 4.3). These placards are required when transporting over
1001 lbs of Class 4.1 or 4.2 materials, or when transporting ANY
quantity of a water reactive material (Class 4.3).
||This placard or label is used to designate cargo that contains
oxidizing materials (Class 5.1). In addition, this class contains
materials that are classified as organic peroxides (Class 5.2),
and in that case the label would read "ORGANIC PEROXIDES" rather
than "OXIDIZER". Placards are required when transporting over 1001
lbs of oxidizers or organic peroxides.
||This class contains poisonous liquids that are designated as inhalation
hazards. If the material is toxic, but not an inhalation hazard
it is placed in Class 6.1. Materials in these classes may NOT
be transported in the same cargo as foodstuffs, feed, or any other
edible substances intended for humans or animals.
In addition to the POISON label, packages of 110 gallon capacity
or less, and that are recognized as "inhalation hazards", must also
be marked "INHALATION HAZARD". Placard is required when transporting
ANY quantity of Class 6 material, and when transporting over
1001 lbs of a Class 6.1 material.
||This label is required on all radioactive materials and equipment.
Packages containing radioactive species must be clearly labeled
with 2 labels on opposite sides of the package. This class is divided
into 3 divisions - I, II and III.
Placard is required on ANY quantity of radioactive material
rated as III; it is not required on materials rated as I or II.
||This placard / label is used to designate any corrosive liquid.
Placard is required whenever the quantity exceeds 1001 lbs of a
||Class 9 materials are those that have not been placed in a hazard
class, but may still pose some degree of danger in transport. Placard
is not required for materials that are not classified. However,
you may placard a material that presents a hazard during transport
and weighs more than 1001 lbs.
||This applies to placarding only and is required when 1001 lbs
or more of material is transported and it is composed of 2 or more
hazard categories. It will replace the specific placards for the
individual classes. An exception is when one single class in a multiple
class transport exceeds 5000 lbs, in which case the placard for
the large load class must be displayed.
[Back to top]
Each person offering for transport a hazardous material must ensure
the package, container or vehicle carries the markings appropriate for
the corresponding hazard. Specific rules and requirements are outlined
in CFR 49 172.300. The following requirements are generally true, though
exceptions are the rule!
- The proper shipping name and the proper identification number (preceded
by UN or NA as appropriate)
- The identification number (below), when required, may be displayed
separately from the warning placard. If so it must consist of black
writing on an orange background. If the identification number is displayed
on the warning placard itself, it shall be black writing on a white
background and will replace the warning wording on the placard, but
not the graphic. The identification number must be affixed to each
side and each end if the packaging has a capacity of 1,000 gallons
or more. It must be affixed on opposite ends if the packaging capacity
is less than 1,000 gallons.
- The markings must be durable, in English and printed legibly.
- They must be displayed on a background of sharply contrasting color.
- They must be un-obscured by labels or attachments.
- The markings must be placed sufficiently far from other markings,
such as advertising, so as not to detract from them or less their
In addition to the above general requirements, some materials require
that specific markings be displayed on packages and on vehicles when
offered for transport. The guidelines for these materials are as follows:
- For radioactive materials, each package must have its weight clearly
marked on the outside of the package. The packaging type (TYPE A or
TYPE B) must be clearly marked on the outside of the package.
||Liquid hazardous materials in non-bulk packaging must be packaged
with the closures upward and be legibly marked with package
orientation markings pointing in the correct upright direction.
Markings that depict arrows for purposes other than to indicate
the upward position may not be used on hazardous liquid materials.
This requirement does not apply to packaging where the interior
package is a metal cylinder.
- Bulk packages which contain materials that are poisonous if inhaled
must be marked with the warning "Inhalation Hazard" on two opposing
sides. Non-bulk packages must be marked with the word "POISON" within
6 inches of the closure.
- Non-bulk packages of materials classified as ORM-D must be marked
on at least one side or end with the ORM-D designation directly below
the proper shipping name of the material. This marking is certification
by the person offering the material for transport that the description,
classification, packaging, marking and labeling are all correct and
appropriate for the material.
[Back to top]
Whenever a hazardous material is offered for transport, it must be
accompanied by proper shipping papers, which fully identify the hazards
The description must fulfill the following requirements:
- If a hazardous material and a non-hazardous material are described
on the same shipping papers, the hazardous material must be:
- named first
- shown in contrasting (highlighted) color on all copies of the
- identified with an "X" in the column marked "HM".
- The shipping description must furnish:
- proper shipping name
- hazard class or division (this from column 3 of the Hazardous
- identification number (this from column 4 of the Hazardous Materials
- packing group (this from column 5 of the Hazardous Materials
- except for empty packages, the total quantity, including unit
for measurement, of the hazardous material.
- Entry must be legible and in English.
- Unless specifically authorized or required, the description may
not contain codes or abbreviations.
- Additional information must follow the basic description.
- Must contain the name of the shipper when transported by water.
- If more than one page is required, the first page must indicate
multiple pages, i.e., "page 1 of 3".
- Shipping paper must show an emergency response telephone number.
- Shipping paper must contain shipper's certification. Click
