TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible.		In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation	Cough.	Local exhaust or breathing protection.
Skin
Eyes		Safety goggles, or eye protection in combination with breathing protection.
Ingestion

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. (Extra personal protection: P3 filter respirator for toxic particles).

EMERGENCY RESPONSE	SAFE STORAGE

IMPORTANT DATA

Physical State; Appearance
COLOURLESS, WHITE OR VARIABLE BLACK, PURPLE, GREEN CRYSTALS

Chemical dangers
Reacts with strong oxidants causing fire and explosion hazard.

Occupational exposure limits
TLV: (respirable fraction) 0.025 mg/m³; A2 (suspected human carcinogen); (ACGIH 2006).
MAK: Carcinogen category: I (DFG 2005).

Routes of exposure
The substance can be absorbed into the body by inhalation.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of long-term or repeated exposure
The substance may have effects on the lungs, resulting in fibrosis (silicosis). This substance is carcinogenic to humans.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 2230°C Melting point: 1610°C Relative density (water = 1): 2.6 Solubility in water: none

NOTES

Depending on the degree of exposure, periodic medical examination is indicated.
CSQZ, DQ 12, Min-U-Sil, Sil-Co-Sil, Snowit, Sykron F300, Sykron F600 are trade names.
