Department of Transportation Regulations
| Please note that this page refers
to federal requirements. State and local regulations
Department of Transportation (DOT) regulations assign the responsibility to the shipper (e.g., hospital) for
properly packaging hazardous materials that are being transported offsite (see
shipper's responsibility in 49
CFR 173.22). It is also the
responsibility of the shipper that each employee involved with packaging is
properly trained (see 49
Healthcare facilities may ship various types of hazardous materials, including chemicals, compressed gases, etc. The information in this section is limited to packaging of regulated medical waste and infectious substances. For information on packaging and shipping other hazardous materials, consult the applicable sections of HERC and the DOT regulations found under Title 49.
The information presented in this section is specific to federal DOT regulations. Individual states may have somewhat different or additional rules. Check with your state agencies.
Packaging and transportation regulations vary, depending on the type of material. The following are important definitions with regard to regulated medical waste and infectious substances.
The term regulated medical waste, is defined differently
by many state and federal agencies.
Under DOT rules, regulated medical waste (RMW) is a
waste or reusable material suspected or known to contain an infectious substance, and is generated
in the diagnosis, treatment, immunization, or biomedical research of humans or
An infectious substance is referred to in DOT regulations as
6.2 material and is defined as a material known or reasonably expected
to contain a pathogen. A pathogen is a
microorganism (including bacteria, viruses, rickettsiae, parasites, fungi) or
other agent, such as a proteinaceous infectious particle (prion) that can cause
disease in humans or animals.
An infectious substance must be assigned the identification number UN 2814, UN 2900, or UN 3373, as appropriate:
Category A: An
infectious substance in a form capable of causing permanent disability or
life-threatening or fatal disease in otherwise healthy humans or animals
when exposure to it occurs. A Category A infectious substance must be
assigned (based on the known medical history or symptoms of the source
patient or animal, endemic local conditions, or professional judgment
concerning the individual circumstances of the source human or animal )
one of two identification numbers:
2814 -- infectious substance affecting humans, or humans and animals, or
2900 -- infectious substance which cause disease only in animals.
Category B: An
infectious substance that is not in a form generally capable of causing
permanent disability or life-threatening or fatal disease in otherwise
healthy humans or animals when exposure to it occurs. This includes
Category B infectious substances transported for diagnostic or
investigational purposes. A Category B infectious substance must be
described as Biological substance, Category B and assigned
identification number UN 3373.
Medical Waste Packaging
Although RMW is by definition an infectious substance, it
does not fall under the packaging requirements for infectious substances (49
CFR 173.196) because of an exception found in 49
CFR 173.134 (see 173.134(c), exceptions for regulated medical waste). Therefore, the applicable DOT regulations
for packaging regulated medical waste are limited to 49
CFR 173.197, which have been reformatted below for easier reading.

Infectious Substances Packaging.
(a) Category B infectious substances. Except as provided in
this paragraph (a), Category B infectious substances are excepted from all
other requirements of this subchapter when offered for transportation or
transported in accordance with this section. Category B infectious substances
offered for transportation or transported under the provisions of this section
are subject to the incident reporting requirements in 171.15 and 171.16 of
this subchapter and to the requirements in 175.75(b) of this subchapter
concerning cargo location. Except as provided in paragraph (a)(9) of this
section, a Category B infectious substance meeting the definition of a hazard
class other than Division 6.2 must be offered for transportation or transported
in accordance with applicable requirements of this subchapter.
Category B infectious substance must be packaged in a triple packaging consisting
of a primary receptacle, a secondary packaging, and a rigid outer packaging.
Primary receptacles must be packed in secondary packaging in such a way that,
under normal conditions of transport, they cannot break, be punctured, or leak
their contents into the secondary packaging.
Secondary packagings must be secured in rigid outer packagings with suitable
cushioning material such that any leakage of the contents will not impair the
protective properties of the cushioning material or the outer packaging.
completed package must be designed, constructed, maintained, filled, its
contents limited, and closed so that under conditions normally encountered in
transportation, including removal from a pallet or overpack for subsequent
handling, there will be no release of hazardous material into the environment.
Package effectiveness must not be substantially reduced for minimum and maximum
temperatures, changes in humidity and pressure, and shocks, loadings and
vibrations normally encountered during transportation. The packaging must be
capable of successfully passing the drop tests in 178.609(d) and (h) of this
subchapter at a drop height of at least 1.2 meters (3.9 feet). Following the
drop tests, there must be no leakage from the primary receptacle, which must
remain protected by absorbent material, when required, in the secondary
packaging. At least one surface of the outer packaging must have a minimum
dimension of 100 mm by 100 mm (3.9 inches).
following mark must be displayed on the outer packaging on a background of
contrasting color. The width of the line must be at least 2 mm (0.08 inches)
and the letters and numbers must be at least 6 mm (0.24 inches) high. The size
of the mark must be such that no side of the diamond is less than 50 mm (1.97
inches) in length. The proper shipping name Biological substances, Category
B must be marked on the outer packaging adjacent to the diamond-shaped mark
in letters that are at least 6 mm (0.24 inches) high.
Category A Infectious Substances

liquid infectious substance, an absorbent material placed between the primary
receptacle and the secondary packaging. The absorbent material must be
sufficient to absorb the entire contents of all primary receptacles.
itemized list of contents enclosed between the secondary packaging and the
primary receptacle or secondary packaging used for infectious substances must
be capable of withstanding, without leakage, an internal pressure producing a
pressure differential of not less than 95 kPa (0.95 bar, 14 psi).
primary receptacle or secondary packaging used for infectious substances must
be capable of withstanding without leakage temperatures in the range of - 40 oC to +55 oC (-40 oF to +131 oF).
(b) Additional requirements for packaging Category A
infectious substances. Category A infectious substances must be packaged according
to the following requirements, depending on the physical state and other
characteristics of the material.
(1) Infectious substances shipped at
ambient temperatures or higher. Primary receptacles must be made of glass, metal, or
plastic. Positive means of ensuring a leakproof seal must be provided, such as
heat seal, skirted stopper, or metal crimp seal. If screw caps are used, they must
be secured by positive means, such as with adhesive tape, paraffin sealing
tape, or manufactured locking closure. Lyophilized substances may also be
transported in primary receptacles that are flame-sealed with glass ampoules or
rubber-stoppered glass vials fitted with metal seals.
(2) Infectious substances shipped
refrigerated or frozen (ice, pre-frozen packs, dry ice). Ice, dry ice, or other
refrigerant must be placed around the secondary packagings or in an overpack with
one or more complete packages marked in accordance with 178.503 of this
subchapter. Interior supports must be provided to secure the secondary packagings
in the original position after the ice or dry ice has dissipated. If ice is
used, the outer packaging or overpack must be leakproof. If dry ice is used,
the outer packaging or overpack must permit the release of carbon dioxide gas
and otherwise meet the provisions in 173.217. The primary receptacle and the
secondary packaging must maintain their integrity at the temperature of the
refrigerant used, as well as the temperatures and pressures of transport by
aircraft to which they could be subjected if refrigeration were lost.
(3) Infectious substances shipped in
liquid nitrogen. The primary
receptacle and the secondary packaging must maintain their integrity at the
temperature of the liquid nitrogen as well as the temperatures and pressures of
transport by aircraft to which they could be subjected if refrigeration were lost.
Refrigerated liquid nitrogen packagings must be metal vacuum insulated vessels
or flasks vented to the atmosphere to prevent any increase in pressure within
the packaging. The use of safety relief valves, check valves, frangible discs,
or similar devices in the vent lines is prohibited. Fill and discharge openings
must be protected against the entry of foreign materials that might cause an
increase in the internal pressure. The package orientation markings specified
in 172.312(a) of this subchapter must be marked on the packaging. The
packaging must be designed to prevent the release of any refrigerated liquid
nitrogen irrespective of the packaging orientation.
(c) Live animals may
not be used to transport infectious substances unless such substances cannot be
sent by any other means. An animal containing or contaminated with an
infectious substance must be transported under terms and conditions approved by
the Associate Administrator for Hazardous Materials Safety.
(d) Body parts, organs or whole bodies meeting the definition of Division 6.2 material must be
packaged as follows:
Division 6.2 packaging, as specified in paragraphs (a) and (b) of this section;
packaging meeting the requirements of 173.197.
A hazmat employer must train all hazmat employees in general awareness
training, function-specific regulatory training, and safety training. For
example, healthcare professionals need training to properly use any packaging
authorized for the transportation of infectious substances.
