IV         FIRE AND EXPLOSION HAZARDS DATA

Flash Point (Method used): N/A                                                            Autoignition Temperature: N/A

Flammable Limits: Upper: N/A  Lower: N/A

Flammability: Slight Flammability.

Extinguishing Media: Use dry chemical, CO₂.

Special Firefighting Procedures: Wear a self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.

Unusual Fire & Explosion Hazards: Moderate explosion hazard when shocked or exposed to heat or by chemical reaction. Perchlorates form explosive mixtures with carbonaceous materials. Fire and explosion hazard when associated with carbonaceous materials, finely divided metals, sulfur, powdered magnesium and aluminum. Reacts violently w/compatible materials. Emits highly to powdered magnesium and aluminum. Reacts violently w/incompatible materials. Emits highly to fumes of Cl^- when heated.

V           HEALTH HAZARD INFORMATION

Effects of Over Exposure:

Inhalation: Perchlorates are irritating to mucous membranes.

Dermal/Eye Contact: Perchlorates are irritating to skin. May cause irritation and inflammation of eyes.

Other (specify): Cesium may cause liver disorder, neuroendocrine disturbance and neuromuscular toxicity leading to irritability and convulsions. Cesium compounds are also known mutagens.

Medical Conditions Generally Aggravated by Exposure: No data

Carcinogenicity: None

EMERGENCY AND FIRST AID PROCEDURES:

EYE CONTACT: Flush eyes with lukewarm water for 15 minutes. Seek medical attention if symptoms persists.

SKIN CONTACT: Wash affected area with soap and water. Seek medical attention if symptoms appear.
