	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! AVOID ALL CONTACT! 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 immediately 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 immediately for medical attention .
Eyes	Pain. Severe deep burns. Loss of vision.	Wear face shield or eye protection in combination with breathing protection.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately 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 immediately 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 DANGER Fatal if inhaled Harmful if swallowed or in contact with skin Causes severe skin burns and eye damage May cause an allergic skin reaction Transportation UN Classification UN Subsidiary Risks: 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. Reacts violently with oxidants, nitric acid and organic nitro compounds. This generates explosion hazard. 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. The effects may be delayed. Medical observation is indicated. See Notes.	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.

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. The effects may be delayed. Medical observation is indicated. See Notes.

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.

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

ENVIRONMENT
Environmental effects of the substance have been adequately investigated, but no significant effects have been found.

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. The odour warning when the exposure limit value is exceeded is insufficient.
