TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Cough. Sore throat. Headache. Laboured breathing. Weakness. See Ingestion.	Closed system and ventilation.	Fresh air, rest. Refer for medical attention.
Skin		Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes	Redness. Pain.	Face shield or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Diarrhoea. Vomiting. Burning sensation in the throat and chest. Shock or collapse.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING

IMPORTANT DATA

Physical State; Appearance
WHITE CRYSTALS OR WHITE POWDER.

Chemical dangers
Upon heating, toxic fumes are formed. Reacts with strong oxidants to produce toxic fumes.

Occupational exposure limits
TLV: (as As) 0.01 mg/m³; A1 (confirmed human carcinogen); BEI issued; (ACGIH 2004).
MAK: Carcinogen category: 1; Germ cell mutagen group: 3A; (DFG 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

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

Effects of short-term exposure
The substance is irritating to the eyes and the respiratory tract. The substance may cause effects on the gastrointestinal tract, cardiovascular system, central nervous system, kidneys, resulting in severe gastroenteritis, loss of fluids and electrolytes, cardiac disorders, kidney impairment and shock. Exposure above the OEL may result in death. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the skin, mucous membranes, bone marrow, liver and peripheral nervous system, resulting in pigmentation disorders, perforation of nasal septum, lesions of blood cells, liver impairment and neuropathy. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes malformations in human babies.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Solubility in water: none	This substance may be hazardous to the environment; special attention should be given to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.

NOTES

Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
Technical material is highly hydrated. Molecular mass and density will vary depending on the hydrated form.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, Emergency Response. October 2005: see section Effects of long-term or repeated exposure.
