	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 51°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. Above 51°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!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Burning sensation. Cough. Headache. Nausea. Shortness of breath. Sore throat. 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	Redness. Serious skin burns.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Eyes	Redness. Blurred vision. Severe deep burns.	Wear face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Shock or collapse. Further see Inhalation.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Rest. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Remove all ignition sources. 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: 3; UN Subsidiary Risks: 6.1; UN Pack Group: III
STORAGE
Fireproof. Separated from food and feedstuffs. See Chemical Dangers. Cool. Dry. Well closed. Keep in a well-ventilated room.
PACKAGING
Do not transport with food and feedstuffs.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-LIGHT-YELLOW LIQUID WITH PUNGENT ODOUR. Physical dangers Chemical dangers Decomposes on burning. This produces toxic and corrosive gases including nitrogen oxides. Reacts violently with oxidants, acids, acid chlorides, acid anhydrides and mercury. Attacks plastics, copper, copper alloys, aluminium, zinc, zinc alloys and galvanized surfaces. Solutions in water may attack glass.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol or vapour, through the skin and by ingestion. Effects of short-term exposure The substance is corrosive to the skin and eyes. The substance is severely irritating to the respiratory tract. Inhalation of the vapour or mist may cause lung oedema. See Notes. The substance may cause effects on the central nervous system.	Inhalation risk No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol or vapour, through the skin and by ingestion.

Effects of short-term exposure
The substance is corrosive to the skin and eyes. The substance is severely irritating to the respiratory tract. Inhalation of the vapour or mist may cause lung oedema. See Notes. The substance may cause effects on the central nervous system.

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
Environmental effects from the substance have not been investigated adequately.

NOTES
Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 55°C. 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. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
