3. COMPOSITION/INFORMATION ON INGREDIENTS
**If Chemical Name/CAS No is "proprietary" and/or Weight-% is listed as a range, the specific chemical identity and/or percentage
of composition has been withheld as a trade secret.**
IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if
present and easy to do. Continue rinsing. Immediately call a poison center or
doctor/physician.
Wash off immediately with soap and plenty of water. Remove contaminated clothing and
shoes. Wash contaminated clothing before reuse. Call a poison center or doctor/physician if
you feel unwell. If skin irritation or rash occurs: Get medical advice/attention.
Remove to fresh air. Seek immediate medical attention/advice.
Call a physician or Poison Control Center.
Most important symptoms and effects
Inhalation: During normal use inhalation is highly unlikely due to the containment of
hazardous materials inside the sealed battery case. However, if the batteries are exposed
to extreme heat or pressure causing a breach in the battery cell case, cadmium fumes and
dust may be emitted. Inhalation of cadmium dusts or fumes may cause throat dryness,
respiratory irritation, headache, nausea, vomiting, chest pain, extreme restlessness and
irritability, pneumonitis and bronchopneumonia. In the case of high concentration exposures
(e.g. above 1 to 5mg/m³ during an eight hour period) death may occur within several days
of exposure.
Ingestion: If the battery case is breached in the digestive tract, the electrolyte may cause
localized burns. Ingestion of cadmium compounds may result in increased salivation,
chocking, nausea, persistent vomiting, diarrhea, abdominal pain, amnesia, tenesmus, and
kidney dysfunction.
Skin Contact: Exposure to the electrolyte inside the battery may result in severe irritation
and chemical burns. Exposure to nickel may cause dermatitis for some sensitive
individuals. May cause an allergic skin reaction.
Eye Contact: Exposure to the electrolyte contained inside the battery may result in severe
irritation and chemical burns.
Indication of any immediate medical attention and special treatment needed

5. FIRE-FIGHTING MEASURES
Suitable Extinguishing Media
Confining and smothering metal fires is preferable rather than applying water. Dry chemical, soda ash, lime or sand.
Unsuitable Extinguishing Media
Specific Hazards Arising from the Chemical
See Section 2, Hazard Statements. Exposure to temperatures above 212 °F can cause venting of the liquid electrolyte, internal
shorting could also cause venting of the electrolyte. There is potential for exposure to iron, nickel, cobalt, rare earth metals (cerium,
lanthanum, neodymium and praseodymium), manganese and aluminum fumes during a fire.
Hazardous Combustion Products See "Specific Hazards" above.
Protective equipment and precautions for firefighters
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full
protective gear.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Use personal protective equipment as required. Avoid contact with skin, eyes or clothing.
The sealed NiMH cells when sleeved are safe if spilled. Non sleeved cells may generate
short- circuits, causing release of alkaline electrolyte mist or liquid. Electrolyte reacts with
zinc, aluminum, tin and other active materials releasing flammable hydrogen gas. In such
case, use self-contained breathing apparatus and protective clothing.
Environmental Precautions
Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. See
Section 12, Ecological Information. See Section 13: DISPOSAL CONSIDERATIONS.
Methods and material for containment and cleaning up
Prevent further leakage or spillage if safe to do so.
Collect all released material in a plastic lined container. Report all spills in accordance with
Federal, State and Local reporting requirements.
Precautions for safe handling
Handle in accordance with good industrial hygiene and safety practice. Avoid contact with
skin, eyes or clothing. Use personal protection recommended in Section 8. Obtain special
instructions before use. Do not handle until all safety precautions have been read and
understood. Wash face, hands, and any exposed skin thoroughly after handling. Do not eat,
drink or smoke when using this product. Do not breathe dust/fume/gas/mist/vapors/spray.
Contaminated work clothing should not be allowed out of the workplace.

Conditions for safe storage, including any incompatibilities
Keep container tightly closed and store in a cool, dry and well-ventilated place. Store away
from heat, sparks, flame. Protect from moisture. Store away from incompatible materials.
Prevent condensation on cells or battery terminals. Elevated temperatures may result in
reduced battery life. Storage temperatures should be within the range of 40°F (5°C) to 77°F
(25°C) in a 65 +/- relative humidity. Accidental short circuit will bring high temperature
elevation to the battery as well as shorten the battery life. Be sure to avoid prolonged short
circuit since the heat generated can burn skin and even rupture the battery cell case.
Batteries packaged in bulk containers should not be shaken. Metal covered tables or belts
used for the assembly of batteries into devices can be the source of short circuits; apply
insulating material to assembly work surfaces. Soldering/Welding: If soldering or welding to
the case is required consult our Technical Department for proper precautions to prevent
seal damage or external short circuit.
Charging: These batteries are designed for recharging. A loss of voltage and capacity of
the battery due to self- discharge during prolonged storage is unavoidable. Charge battery
before use. Observe the specified charge rate since higher rates can cause a rise in
internal gas pressure which may result in damaging heat generation or cell rupture and/or
venting. Do not mix with other battery types.
Potential incompatibilities: The battery cells are encased in a non-reactive container;
however, if the container is breached, avoid contact of internal battery components with
acids, aldehydes and carbonate compounds.

14. TRANSPORT INFORMATION
Power-Sonic sealed Nickel Metal Hydride batteries are considered to be "dry cell" batteries
and are unregulated for purposes of transportation by the U.S. Department of
Transportation (DOT), International Civil Aviation Administration (ICAO), International Air
Transport Association (IATA) and the International Maritime Organization (IMO).
The only requirements for shipping these batteries by DOT is Special Provision 130 which
states: "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). The only requirements for
shipping these batteries by ICAO and IATA is Special Provision A123 which states: "An
electrical battery or battery powered device having the potential of dangerous evolutions 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 transportation."
The International Maritime Dangerous Goods Code (IMDG) regulate them for ocean
transportation under Special Provision 304 which says: "Batteries, dry, containing corrosive
electrolyte which will not flow out of the battery if the battery case is cracked are not subject
to the provisions of this Code provided the batteries are securely packed and protected
against short-circuits. Examples of such batteries are: alkali-manganese, zinc-carbon,
nickel metal hydride and nickel-cadmium batteries.
