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		STRICT HYGIENE!
Inhalation	Burning sensation. Cough. Laboured breathing. Sore throat. Shortness of breath. Symptoms may be delayed (see Notes).	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Corrosive. Redness. Pain. Blisters. Skin burns.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes	Corrosive. Redness. Pain. Severe deep burns.	Face shield 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	Burning sensation. Sore throat. Nausea. Abdominal cramps. Vomiting. Abdominal pain. Diarrhoea. Shock or collapse.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in dry sand or inert absorbent and remove to safe place. Personal protection: complete protective clothing including self-contained breathing apparatus.

IMPORTANT DATA

Physical State; Appearance
YELLOWISH OR COLOURLESS LIQUID

Chemical dangers
The substance decomposes on heating producing toxic and corrosive fumes. Reacts with water to produce heat and corrosive fumes. The solution in water is a strong acid, it reacts violently with bases and is corrosive.

Occupational exposure limits
TLV: (as Se) 0.2 mg/m³ as TWA; (ACGIH 2004).
MAK: (as Se) (Inhalable fraction) 0.05 mg/m³; Peak limitation category: II(4); Carcinogen category: 3B; Pregnancy risk group: C; (DFG 2004).

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

Inhalation risk
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

Effects of short-term exposure
The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes). Medical observation is indicated.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the respiratory tract, gastrointestinal tract, central nervous system and liver, resulting in nasal irritation, persistent garlic odour, stomach pain, nervousness and liver impairment.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 176.4°C Melting point: 8.5°C Relative density (water = 1): 2.42 Solubility in water: reaction Vapour pressure, Pa at 34.8°C: 132	The substance is harmful to aquatic organisms.

NOTES

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Do NOT take working clothes home.
