NiMH battery packs supplied for use in rechargeable electronic scales and balances. Not recommended for any
other use. Not to be confused with sealed lead acid batteries (SLA) used in some of our product range.

________________________________________________

Section 2, Hazard(s) identification

For the battery cell, chemical materials are stored in a hermetically sealed metal case, designed to
withstand temperatures and pressures encountered during normal use. As a result, during normal
use, there is no physical danger of ignition or explosion and chemical danger of hazardous material
leakage. However, if exposed to a fire, added mechanical shocks, decomposed, added electric
stress by misuse, the gas release vent will be operated. The battery cell case will be breached at the
extreme. Hazardous materials may be released. If heated strongly or burned, acrid or harmful fume
may be emitted.

Human health effects:
Inhalation: The electrolyte inhalation affects the respiratory tract membrane and the lungs. Fume
may cause a cough, chest pain and dyspnea. Bronchitis and pneumonia may occur. Possibly
could be carcinogen.
Skin contact: The electrolyte skin contact affects the skin seriously and may cause dermatitis.
Eye contact: The electrolyte leaked from the battery cell is strong alkali. When it goes into an eye,
the cornea may be affected and it may lead to blindness.
Ingestion: The electrolyte ingestion irritates the mouth and the throat seriously results in vomiting,
nausea, hematemesis, stomach pains and diarrhea.
Environmental effects:
No known significant environmental effects. Efforts should be made to recycle as the product does
not degrade naturally.

Section 4, First-aid measures

Internal cell materials of an opened battery cell
・Inhalation :
Cover the victim in a blanket, move to the place of fresh air and keep quiet. Seek medical attention
immediately. When dyspnea (breathing difficulty) or asphyxia (breath-hold), give artificial respiration
immediately.
・Skin contact :
Remove contaminated clothes and shoes immediately. Wash the adherence or contact region with
soap and plenty of water. Seek medical attention immediately.

・Eye contact :
Immediately flush eyes with water continuously for at least 15 minutes. Seek medical attention
immediately.
A battery cell and internal cell materials of an opened battery cell
・Ingestion :
Do not induce vomiting. Seek medical attention immediately.

Section 5, Fire-fighting measures

If fire or explosion occurs when batteries are on charge, shut off power to charger.

In case of fire, it is permissible to use any class of extinguishing medium on these batteries or their packing
material. Cool exterior of batteries if exposed to fire to prevent rupture.

In case of fire where nickel metal hydride batteries are present, apply a smothering agent such as METL-X,
sand, dry ground dolomite, or soda ash, or flood the area with water. A smothering agent will extinguish
burning nickel metal hydride batteries. Water may not extinguish burning batteries but will cool the adjacent
batteries and control the spread of fire. Burning batteries will burn themselves out. Virtually all fires involving
nickel metal hydride batteries can be controlled with water. When water is used, however, hydrogen gas may
evolve. In a confined space, hydrogen gas can form an explosive mixture. In this situation, smothering agents
are recommended.

Fire fighters should wear self-contained breathing apparatus.

Burning nickel metal hydride batteries can produce toxic fumes including oxides of nickel, cobalt, aluminum,
manganese, lanthanum, cerium, neodymium, and praseodymium.

Section 6, Accidental release measures

Steps to Be Taken in Case Material is Released or Spilled:
Batteries that are leaking should be handled with rubber gloves. Avoid direct contact with electrolyte.

Method of recovery and neutralization :
Dilute any leaked electrolyte with water and neutralize with diluted sulfuric acid. The leaked solid is
to be moved to a container. Place of leakage to be fully flushed with water.

Wear protective clothing and a positive pressure Self-Contained Breathing Apparatus (SCBA)

Section 7, Handling and storage

Storage:
Store in a cool, well-ventilated area. Elevated temperatures can result in shortened battery life.
Mechanical Containment:
Never seal or encapsulate nickel metal hydride batteries. Do not obstruct safety release vents on batteries.
Encapsulation (potting) of batteries will not allow cell venting and can cause high pressure rupture.
Handling:
Accidental short circuit for a few seconds will not seriously affect the battery. However, this battery is
capable of delivering very high short circuit currents. Prolonged short circuits will cause high cell
temperatures which can cause skin burns. Sources of short circuits include jumbled batteries in bulk
containers, metal jewelry, and metal covered tables or metal belts used for assembly of batteries into
devices.
Do not open battery. The negative electrode material may be pyrophoric. Should an individual cell from a

battery become disassembled, spontaneous combustion of the negative electrode is possible. This is much

more likely to happen if the electrode is removed from its metal container. There can be a delay between
exposure to air and spontaneous combustion.
