III. FIRE AND EXPLOSION DATA

Capacitors can spark if discharged into a short-circuit and the case can burst if subjected to excessive voltage or
temperature.

IV. HEALTH HAZARD DATA

Electrocution Risk. Avoid personal contact with high-voltages which may be present on charged capacitors.
Electrolyte contains sulfuric acid. Exposure to electrolyte is not possible unless case or seal is compromised. Avoid
conditions which can burst case (see Section III). Sulfuric acid can cause serious burns to all tissues contacted.
Sulfuric acid is exceedingly dangerous to the eyes. Protect skin and eyes from contact. Overexposure from
inhalation may lead to pulmonary edema.. Long exposures are claimed to lead to respiratory infections, emphysema,
and digestive disturbances. Sulfuric acid not normally present outside case. To avoid exposure, do not open case.

Emergency First Aid Flush exposed skin and eyes immediately with cold water. Seek physician, especially if
eyes are exposed.


V. SPECIAL INSTRUCTIONS

Avoid exposure to finely divided tantalum. Normal exposure to tantalum metal is not hazardous. Do not cut, drill,
puncture, grind, or machine case. Do not incinerate.
