Classification nameClassification standard not applicable to batteries.

Hazardousness

Charging a battery generates hydrogen and oxygen gases. Exposureof 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 a lossof 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 suchas animals and plants.

Emergency Measures
When electrolyte
contacts the eyes

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

When electrolyte isattached to skin:

Immediately wash it down with a large quantity of water, and thoroughly
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, anddrink another large quantity of fresh water. Then, have immediate
medical treatment. Do not disgorge the electrolyte or water that has
been drunk. Do not try to neutralize.

Action at the Time of Fire
Fire fighting method

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

Action at The Time of Electrolyte Leak or 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 and Storing 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.

Exposure Inhibiting Device
Keep the handling and storing precautions especially during charging when Hydrogen gas and sulfuric
acid mist are generated.
Keep the regulations for export since electrolyte (dilute sulfuric acid) may leak in case the battery isturned, fallen or given a strong impact.
