ClassificationofHazardousness

andPoisonousmaterials

Classification nameClassification standard not applicable to batteries.

Hazardousness

Charging a battery generates hydrogen and oxygen gases.
Exposure of fire to them may catch a fire, resulting in an explosion.

Poisonous materials

Exposure of electrolyte to skin or an eye may result in a burn or aloss of eyesight. Lead and lead compounds, chemicals known that
there are probably carcinogenic to humans(Listed Group2 in IARC).

Effect on Environment

Highly concentrated electrolyte may adversely affect living things
such as animals and plants.

Emergency Measures
When electrolyte(mist)is inhaled

Remove from exposure, and have medical treatment.

When electrolyte
contacts the eyes

Immediately flush the eye sufficiently with water, and have
immediate medical treatment.

When electrolyte is
attached to skin

Immediately wash it down with a large quantity of water, andthoroughly wash the skin with soap. If there is a fear of burn, have
immediate medical treatment.

When electrolyte isswallowed

Immediately rinse the mouth with a large quantity of fresh water,and drink another large quantity of fresh water. Then, have
immediate medical treatment. Do not disgorge the electrolyte orwater that has been drunk. Do not try to neutralize.

Fire fighting method
Actionat

TheTimeofElectrolyte

Extinguish a fire using a fire extinguisher of dry powder agent, foam
agent or non-combustible gas.
Leakor

Outflow

Neutralize the leaked electrolyte with soda bicarbonate or slaked
lime, and then wash it down with massive amount of water. (At thattime, be sure to wear protective goggles, gloves, and gum boots.)
Handling

ExposureandStoring

Precautions

Handling:• Do not put a fire close to the battery. Do not short it between theterminals.
• Charge the battery in a well-ventilated room.

Storing:

Choose a place that is not exposed to high temperatures, highhumidity, wind and rain, direct sunlight, fire, poisonous gasses,droplets, dust generation or ingress, or submersion.
