	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 35°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. Above 35°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! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Burning sensation. Cough. Laboured breathing. Shortness of breath. 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. See Notes.
Skin	MAY BE ABSORBED! Redness. Pain. Skin burns. Blisters.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Eyes	Redness. Pain. Blurred vision. Severe deep burns.	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	Abdominal pain. Burning sensation. Cough. Diarrhoea. Nausea. Shock or collapse. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. 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.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 8; UN Subsidiary Risks: 3; UN Pack Group: I
STORAGE
Fireproof. Separated from strong oxidants and acids. Dry.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS HYGROSCOPIC LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers Chemical dangers Decomposes on burning. This produces toxic fumes of nitrogen oxides and carbon monoxide. The substance is a medium strong base. Reacts with strong oxidants. This generates fire hazard. Attacks plastics, rubber and coatings. Unstable if stored in copper or zinc containers.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation, 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.	Inhalation risk A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure The substance may have effects on the liver and kidneys.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation, 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.

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

Effects of long-term or repeated exposure
The substance may have effects on the liver and kidneys.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 20 ppm as TWA; (skin); A4 (not classifiable as a human carcinogen). MAK: 36 mg/m³, 10 ppm; peak limitation category: I(2); pregnancy risk group: D. EU-OEL: 36 mg/m³, 10 ppm as TWA; 72 mg/m³, 20 ppm as STEL

ENVIRONMENT

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. 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.
