TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Water spray, carbon dioxide, foam, powder.
EXPLOSION	Above 91°C explosive vapour/air mixtures may be formed.	Above 91°C use a closed system, ventilation.

EXPOSURE		AVOID ALL CONTACT!
Inhalation	Dizziness. Drowsiness. Headache. Nausea.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	MAY BE ABSORBED! (See Ingestion)	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes		Safety spectacles or eye protection in combination with breathing protection.	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion	Blue lips or fingernails. Blue skin. Dizziness. Drowsiness. Headache. Nausea. Unconsciousness.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Chemical protection suit. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place.

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-61S1711-L NFPA Code: H3; F0; R0	Separated from strong oxidants, acids, acid anhydrides, acid chlorides, hypochlorites, halogens, food and feedstuffs. Well closed. Store in an area without drain or sewer access.

IMPORTANT DATA

Physical State; Appearance
YELLOW LIQUID, WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR.

Physical dangers
The vapour is heavier than air.

Chemical dangers
The substance decomposes on burning producing toxic and corrosive fumes including nitrogen oxides. Reacts violently with strong oxidants. Reacts with hypochlorites forming explosive chloroamines. Reacts with acids, acid anhydrides, acid chlorides and halogens. Attacks plastic and rubber.

Occupational exposure limits
TLV not established. See Notes.
MAK: skin absorption (H); Carcinogen category: 2; (DFG 2006).

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

Inhalation risk
A harmful contamination of the air will be reached slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

Effects of short-term exposure
Exposure at high levels could cause lowering of consciousness. Exposure at high levels may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure
The substance may have effects on the blood, resulting in anaemia. The substance may have effects on the liver. This substance is possibly carcinogenic to humans.

NOTES

Do NOT take working clothes home.
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
TLV only established for mixed isomers, see ICSC 0600.
