Advisory Guidance; Transportation of Batteries and Devices That
Contain Batteries
AGENCY: Research and Special Programs Administration (RSPA), DOT.
ACTION: Advisory guidance.
-----------------------------------------------------------------------
SUMMARY: RSPA has become aware of several incidents that recently
occurred where heat generated by batteries or devices that contain
batteries have caused smoke and/or the initiation of a fire while the
device or article was being transported in commerce. This suggests that
some persons engaged in the offering of batteries and such devices for
transportation may not be fully aware of the requirements and
prohibitions of the Hazardous Materials Regulations (HMR) applicable to
such devices. This advisory guidance is to remind anyone offering for
transportation or transporting such devices that electrical storage
devices or articles that contain batteries are forbidden from
transportation unless properly packaged as to be protected from such an
occurrence.
FOR FURTHER INFORMATION CONTACT: Eric Nelson, Office of Hazardous
Materials Standards, RSPA, Department of Transportation, 400 Seventh
Street, SW., Washington, DC 20590-0001, Telephone (202) 366-8553.
SUPPLEMENTARY INFORMATION: RSPA has been made aware of several
incidents in which batteries or other devices that contain batteries
have short-circuited or otherwise functioned in such a manner so as to
generate heat, smoke, or initiate a fire while being transported in
commerce. This advisory guidance is intended to remind persons offering
for transportation, or personally transporting any battery or
electrical device of their responsibility under the Hazardous Materials
Regulations (49 CFR parts 171-180) that any battery or electrical
device that could create sparks or generate heat may only be offered
for transportation or transported when adequately protected from such
an occurrence.
I. Background
In May, 1994, while being delivered to a handling agent by road, a
shipment of small lithium batteries destined for Gatwick airport in
London, England, was found emitting smoke from a Unit Loading Device.
The shipment consisted of batteries, approximately the size of a dime
and about 5mm high, which had been tossed loosely in a box. The
batteries apparently short-circuited when exposed battery terminal tabs
came into contact with other batteries, and subsequently started a fire
that significantly damaged the shipment. The UK Civil Aviation
Authorities investigated the incident. The shipper was fined
1200 with 300 additional costs being paid.
In February, 1996, 106 packaged lawnmowers with an electrical
battery installed were offered to an air carrier for transportation.
While in an air cargo facility, and after being transported on two
separate flights, smoke was discovered coming from one of the boxes.
Air cargo personnel determined that an installed battery was dislodged
and short-circuited, causing the wiring, plastic housing, and battery
to burn and melt. The air carrier immediately took action to locate the
other packages, which were in the process of being transported to other
destinations throughout the United States. The air carrier returned
three airborne flights and two taxiing aircraft to the airport, and
held 11 flights preparing to depart until all 106 packages were
accounted for. Approximately 50 of the 106 lawnmower batteries short-
circuited, and several burned sufficiently to char
[[Page 36744]]
the packaging in which they were being shipped.
A November, 1997 incident involved a fiberboard box packaging
containing non-spillable, wet electric storage batteries offered to an
air carrier for transportation. The shipment was picked up by a
messenger service for delivery to the air carrier's cargo facility. The
package was discovered burning prior to air transport, the probable
cause of which was short-circuiting of the battery caused by storage of
cables directly on top of the battery. The short-circuit generated
enough heat to ignite nearby combustible materials.
RSPA has become aware of several other occurrences of passenger
baggage that have been discovered smoldering or burning as a result of
battery short-circuits. These batteries include camcorder, camera, or
other dry-cell general use batteries that have short-circuited because
of coming into contact with keys or other metallic items packed in
proximity to the batteries. When such a short-circuit occurs, the
temperature of the device or battery can quickly rise to a point that
causes leakage of the battery or ignites nearby combustibles such as
packaging materials or suitcase linings.
Based on these and other reports, RSPA is concerned that some
persons offering for transportation or transporting batteries or
devices that contain batteries may not be fully aware of the applicable
provisions of the Hazardous Materials Regulations (HMR; 49 CFR parts
171-180). During air transport, leakage from batteries, smoke and/or
fire in cargo compartments can pose a grave risk to transportation
safety.
The serious potential risks posed to flight safety by batteries and
devices that contain batteries, in particular where the battery is not
otherwise subject to regulation, is specifically addressed by RSPA and
the International Civil Aviation Organization (ICAO). On March 5, 1999,
RSPA published in the Federal Register (64 FR 10742) a final rule in
Docket No. RSPA-98-4185 (HM-215C) that amended the Hazardous Material
Table to add, among other things, special provision 130 to the entry,
Battery, dry, not subject to the requirements of this subchapter. This
special provision, codified at Sec. 172.102, identifies conditions that
must be met before dry batteries that are not otherwise subject to the
HMR may be offered for transportation or transported in commerce. It
reads as follows:
``130. Batteries, dry are not subject to the requirements of this
subchapter only when they are offered for transportation in a manner
that prevents the dangerous evolution of heat (for example, by the
effective insulation of exposed terminals).''
In addition, Sec. 173.21 (c) specifies that electrical devices that are
likely to create sparks or generate a dangerous quantity of heat,
unless packaged in a manner that precludes such an occurrence, may not
be offered for transportation in commerce.
In the 1999/2000 edition of the ICAO Technical Instructions for the
Safe Transportation of Dangerous Goods, the following prohibitive
statement appears in relation to electric storage batteries not listed
in the Dangerous Goods List (Table 2-14) or otherwise subject to the
provisions of, the Technical Instructions:
``Any electrical battery or battery-powered device having the
potential of dangerous evolution of heat that is not prepared so as
to prevent a short circuit (e.g., in the case of batteries, by the
effective insulation of exposed terminals; or, in the case of
equipment, by disconnection of the battery and protection of exposed
terminals) is forbidden from transport.'' (Special Provision A123,
pg. 2-12-8)
II. Requirements for the Transportation of Electrical Devices
Where the HMR permit batteries to be offered for transportation,
either separately or installed in equipment, batteries must be
protected against short circuits. The following discusses types of
batteries which are regulated by the HMR. Wet batteries: Batteries,
wet, filled with acid, UN 2794, and Batteries, wet, filled with alkali,
UN 2795, are those that contain corrosive battery fluid, and are
subject to the packing requirements of Sec. 173.159. Wet ``non-
spillable'' batteries: Batteries, wet, nonspillable, UN 2800, are wet
batteries which are capable of withstanding leakage of battery fluid
when subjected to vibration and pressure differential tests, as
specified in Sec. 173.159(d)(3). These batteries are excepted from all
other requirements of the HMR, provided they meet the requirements of
Sec. 173.159 (d)(1), (d)(2), and (d)(3). Batteries containing sodium:
Batteries, containing sodium, UN 3292, are batteries that contain a
material that, by contact with water, are liable to become
spontaneously flammable or give off flammable or toxic gas at a rate
greater than 1 liter per kilogram of the material per hour. These
batteries are subject to the packaging requirements of Sec. 173.189.
Lithium batteries: Lithium batteries, UN 3090, and Lithium batteries,
contained in equipment, UN 3091, are batteries which contain lithium
substances that react dangerously with water. Regulated batteries
contain, for liquid cathodes, more than 0.5 grams of lithium per cell,
or containing an aggregate of over 1.0 gram of lithium or lithium
alloy, and batteries which contain solid cathodes, 1.0 gram of lithium
or lithium alloy per cell, or an aggregate of over 2.0 grams of lithium
or lithium alloy. These batteries are subject to the packaging
requirements of Sec. 173.185. Certain lithium batteries are not subject
to the requirements of the HMR provided they meet the requirements of
Sec. 173.185(c). Batteries containing potassium hydroxide solids:
Batteries, dry, containing potassium hydroxide solid, UN 3028, are
those which contain corrosive solids, and are subject to the packaging
requirements of Sec. 173.213.
Dry batteries that are not otherwise subject to the requirements of
the HMR are batteries such as rechargeable camera, cell phone, and dry
carbon and alkaline batteries which are commonly used by consumers.
These batteries are otherwise excepted from requirements of the HMR
when offered for transportation or transported in commerce provided the
battery is packaged in a manner that prevents the generation of a
dangerous quantity of heat that may result from short-circuiting. For
the purpose of Sec. 173.21 (c), ``dangerous quantity of heat'' is
considered, in part, to be a sufficient amount of energy to cause
leakage of the battery contents, smoke or fire, or personal injury.
Even without a short-circuit condition existing, a component in
circuitry connected to a battery may become heated to a point where
combustion is initiated in the component itself, or in near-by
combustible materials, even if the battery or the device in which the
battery is installed functions normally. RSPA has become aware of
several incidents in which devices that contain batteries, although
shipped in compliance with Sec. 173.159, have produced dangerous
quantities of heat while in transportation in commerce. RSPA is
evaluating the conditions surrounding these incidents.
An example is a November 1997 incident in which a device known
commonly as an Uninterruptible Power Source was offered to an air
carrier for transportation in commerce. An Uninterruptible Power
Source, a device consisting of a battery with associated circuitry, is
used both to provide electrical surge protection to computers and to
supply emergency power to computers in the event of a loss of normal
power. After being transported on at least one flight, the power
source, packed in a fiberboard box, was
[[Page 36745]]
discovered burning and smoking at a cargo sort facility. A subsequent
investigation revealed that the burning initiated in a printed circuit
board, with the source of energy being a battery within the device.
Another example of a condition of a component in circuitry
connected to a battery may become heated to a point where combustion is
initiated in the component itself, or in near-by combustible materials,
even when the device functions normally is a properly operating, high-
intensity flashlight used by scuba divers. Such devices, packed in
checked baggage and unintentionally activated (i.e., by movement of the
on/off switch to the ``on'' position), have started fires in passenger
baggage.
Airline passengers and persons who offer such electrical devices
for transportation as carry on baggage, checked baggage, or as cargo,
are responsible for assuring that appropriate means are taken to
protect against dangerous levels of heat from inadvertent activation or
short-circuit of the electrical device in transportation. Individuals
who carry any battery-powered electrical device in their luggage should
take care not to pack it in a manner that may lead to a short-circuit
by contact with keys or other metallic articles, or its inadvertent
activation while in transportation. To address this potential risk, the
HMR contains an overriding provision in Sec. 173.21, Forbidden
materials and packages. Materials forbidden by Sec. 173.21 may not be
offered for transportation, or transported in commerce. This section
extends the forbidden designation beyond materials specifically
identified in the Hazardous Materials Table or elsewhere in the HMR, to
various additional general categories including:
``Electrical devices which are likely to create sparks or generate a
dangerous quantity of heat, unless packaged in a manner which
precludes such an occurrence.''
Any electrical device, even one not otherwise subject to the HMR
(either by specific exception from the HMR, or because the device and
its power source contains no material meeting the definition of a
hazardous material), is forbidden from being offered for
transportation, or transported, if the device is likely to produce
sparks or a dangerous quantity of heat.
III. Reminder to Offerers and Transporters
Any persons who offers or transports a battery or an electrical
device with an installed battery, including power sources, lights or
torches, power tools, and other related articles are encouraged to
carefully review this guidance, to examine all of their procedures, and
where necessary, to take measures to prevent potential incidents in
transportation. While evaluating whether such devices are likely to
produce sparks or generate a dangerous quantity of heat, environmental
conditions normally encountered in transportation must be taken into
account, including temperature, humidity, vibration, impacts from rough
handling and other relevant factors. In addition, the possibility of
product manufacturing variations such as contamination, spacings, and
loose parts should be taken into account.
Persons are reminded that the offering for transportation of any
forbidden material in violation of the HMR subjects the offerer to
enforcement action, including, but not limited to, significant civil
penalties and appropriate judicial remedies. Furthermore, a willful
violation of the HMR, or the reckless offering of a material for
transportation in violation of the HMR, is subject to criminal
penalties of up to 5 years in prison and/or fines.
