TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, water spray, foam, carbon dioxide.
EXPLOSION	Finely dispersed particles form explosive mixtures in air.	Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE		AVOID ALL CONTACT!
Inhalation		Local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Safety goggles, or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Personal protection: P2 filter respirator for harmful particles.	Xi Symbol N Symbol R: 43-50/53 S: (2-)24-37-60-61

EMERGENCY RESPONSE	SAFE STORAGE
	Separated from acids.

IMPORTANT DATA

Physical State; Appearance
YELLOW CRYSTALS, WITH PUNGENT ODOUR.

Chemical dangers
The substance decomposes on burning producing toxic and irritating fumes (sulfur oxides, nitrogen oxides). Reacts with acids or acids fumes to produce toxic fumes (nitrogen oxides, sulfur oxides).

Occupational exposure limits
TLV not established.
MAK: 4 I mg/m³; Sh; Carcinogen category: 3B; Pregnancy risk group: C; (DFG 2004).

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

Effects of short-term exposure
The substance is irritating to the eyes.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 180-182°C Density: 1.42 g/cm³ Solubility in water: 0.1 g/100 ml Flash point: 200°C c.c. Auto-ignition temperature: 628°C Explosive limits, vol% in air: 15-? Octanol/water partition coefficient as log Pow: 2.41	This substance may be hazardous to the environment; special attention should be given to fish.

NOTES

Do NOT take working clothes home.
