IV FIRE AND EXPLOSION H AZARDS DATA
Flash Point (Method used): N/A Autoignition Temp: No Data
Flam mab le Limits: Upper: N/A Lower: N/A
Extingu ishing Media: Flammable solid in powdered form. If involved in fire, do not use water, CO 2, or halogenated extinguishing
agents. Use dry chemical extinguishing agents, dry sand or dry ground dolomite.
Special Fire Fighting Procedures: No special firefighting procedures needed. Use normal procedures which include wearing
NIOSH/MSHA approved self-contained breathing apparatus, flame and chemical resistant clothing; hats, boots and gloves. If without
risk, rem ove ma terial from th e fire area. Co ol container with water fro m m axim um distance. Fu me s from fire are haza rdous. Isolate
runoff to prevent environmental pollution.
Unusual Fire and Explosion Hazard: Elemental silicon is flamm able when exposed to flame or by chemical reaction with oxidizing
agents. May have a violent reaction with alk ali carbon ates; oxidan ts; (Al+PbO); Ca; CsC 2; CaF 2; F 2; IF3; MnF 3; Rb2C 2; FNO; AgF;
and N aK alloy . When hea ted it will react with w ater or steam to prod uce hy drog en gas.

investigated and recorded.
Acute E ffects:
Inhalation: May cause abrasive irritation.
Ingestion: No acute health effects recorded.
Skin : May cause abrasive irritation.
Eye: Dust and powder may cause abrasive irritation.
Chro nic Effects: No chronic health effects recorded.
Target Organs: No target organs recorded.
Medical Conditions, If Any, Aggravated by the Chemical: Pre-existing resp iratory disord ers.
Carcino genicity: NTP: No IARC: No OSHA: No
EMERG ENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air. Seek imm ediate medical attention.
INGESTION: No data available but one should obtain medical attention.
SK IN: Remove contaminated clothing, flood skin with a large amount of water. If irritation persists seek medical attention.
EYE: Imm ediately flush eyes, including under eyelids, with large amounts of water, for at least 15 minutes. Call a physician.
