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!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Abdominal pain. Confusion. Diarrhoea. Dizziness. Drowsiness. Headache. Vomiting. Loss of muscular coordination. Paralysis. Symptoms may be delayed (see Notes).	Closed system and ventilation.	Fresh air, rest. Refer for medical attention.
Skin	Skin disorders. (Further see Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes		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	Difficulty in swallowing. Abdominal pain. Confusion. Diarrhoea. Dizziness. Dullness. Headache. Vomiting. Loss of muscular coordination. Paralysis. (Further see Inhalation).	Do not eat, drink, or smoke during work.

IMPORTANT DATA
Physical State; Appearance COLOURLESS SOLID IN VARIOUS FORMS. Chemical dangers The substance decomposes on heating or producing toxic fumes including arsenic (see ICSC 0013). Occupational exposure limits TLV not established. MAK not established.	Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. 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 See Notes.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point (decomposes): 160°C Relative density (water = 1): 1.76 Solubility in water: poor

NOTES

Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of systemic arsenic poisoning do not become manifest until hours after the exposure.
Card has been partly updated in October 2005. See sections EU classification, Emergency Response.
