	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 97°C explosive vapour/air mixtures may be formed.	NO open flames. Above 97°C use a closed system, ventilation and explosion-proof electrical equipment.	Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS! STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Burning sensation. Laboured breathing. Symptoms may be delayed. See Notes.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Pain. Serious skin burns.	Protective gloves. Protective clothing.	First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
Eyes	Pain. Severe deep burns. Loss of vision.	Wear 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 refer for medical attention.
Ingestion	Burning sensation. Abdominal pain. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Personal protection: complete protective clothing including self-contained breathing apparatus.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 8; UN Pack Group: II
STORAGE
Separated from strong oxidants, acids, organic nitro compounds and food and feedstuffs. Keep in a well-ventilated room.
PACKAGING
Unbreakable packaging. Put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-YELLOW VISCOUS HYGROSCOPIC LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers The vapour is heavier than air. Chemical dangers Decomposes on burning. This produces toxic and corrosive gases including nitrogen oxides. The solution in water is a strong base. It reacts violently with acid and is corrosive. Reacts violently with oxidants, nitric acid and organic nitro compounds. Attacks many metals in the presence of water.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Effects of short-term exposure The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.	Inhalation risk A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma.

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.

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

OCCUPATIONAL EXPOSURE LIMITS
TLV: 1 ppm as TWA; (skin). MAK sensitization of skin (SH)

ENVIRONMENT

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 are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered. The odour warning when the exposure limit value is exceeded is insufficient.
