MATERIAL SAFETY DATA SHEET

CHENER BATTERY

4. First aid measures (continued)

On ingestion: Batteries lodged in the esophagus should be removed immediately since leakage, caustic

burns and perforation can occur as soon as 4-6 hours after ingestion. Irritation, including

caustic burns to the internal/external mouth areas, may occur following exposure to a leaking

battery. An initial x-ray should be obtained promptly to determine battery location. Published

reports recommend removal from the esophagus be done endoscopically (under direct

visualization). Batteries beyond the esophagus need not be retrieved unless there are signs

of injury to the GI tract or a large diameter battery fails to pass the pylorus. If asymptomatic,

follow-up x-rays are necessary only to confirm passage of larger batteries. Confirmation by

stool inspection is preferable under most circumstances. If mouth area irritation/burning has

occurred, rinse the mouth and surrounding area with clear, tepid water for at least 15

minutes. If irritation, injury or pain persists, consult a physician.

Notes to Physician: The primary acutely toxic ingredient is concentrated (35%) potassium hydroxide.

Anticipated potential leakage of potassium hydroxide is 0.05 to 0.5 ml.

5. Fire fighting measures

Suitable extinguishing media: As appropriate for adjacent fire.

Special protective equipment: In fires involving large quantities of product, use self-contained breathing

apparatus and full protective clothing.

Further information: Hazardous decomposition products may be produced. (Sec. 10).

6. Accidental release measures

Personal precautions: Caustic potassium hydroxide may be released from leaking or ruptured batteries.

Avoid eye or skin contact and inhalation of vapours. Increase ventilation. Clean up

personnel should wear appropriate protective gear.

Environmental precautions: Not applicable

Methods for cleaning up: Not applicable

7. Handling and storage

Handling

Avoid mechanical or electrical abuse. Batteries may explode, pyrolize or vent if disassembled, crushed,

recharged or exposed to high temperatures. Install batteries in accordance with equipment instructions.

Replace all batteries in equipment at the same time. Do not carry batteries loose in pocket or bag.

Storage

Store at room temperature.

8. Exposure controls and personal protection

Personal protective equipment

Respiratory equipment: None required under normal use conditions.

Hand protection: None required under normal use conditions. Use neoprene, rubber or nitrile gloves

when handling leaking batteries.

Eye protection: None required under normal use conditions. Wear safety glasses when handling leaking

batteries.

General safety and hygiene measures: Use only as directed.
