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. NO contact with oxidants.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 70C explosive vapour/air mixtures may be formed.
Above 70C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

Inhalation Blue lips or finger nails. Blue skin. Headache. Dizziness. Laboured breathing. Convulsions. Increased heartbeat. Vomiting. Weakness. Unconsciousness. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin MAY BE ABSORBED! Redness. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness. Pain.
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 take to a doctor.
Ingestion (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. See Notes.

ANILINE ICSC: 0011
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS OILY LIQUID, WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR OR LIGHT.

CHEMICAL DANGERS:
The substance decomposes on heating at temperatures above 190C, producing toxic and corrosive fumes (ammonia and nitrogen oxides) and flammable vapours. The substance is a weak base. Reacts vigorously with strong oxidants causing fire and explosion hazard. Reacts violently with strong acids. Attacks copper and its alloys.

OCCUPATIONAL EXPOSURE LIMITS:
TLV (as aniline and homologues): 2 ppm; skin A3 (ACGIH 2000). MAK: 2 ppm; 3b, skin (2000)
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion, also as a vapour!

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin. The substance may cause effects on the blood, resulting in the formation of methaemoglobin. Exposure at high levels may result in death. Medical observation is indicated. The effects may be delayed. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood, resulting in formation of methaemoglobin.
PHYSICAL PROPERTIES
Boiling point: 184C
Melting point: -6C
Relative density (water = 1): 1.02
Solubility in water, g/100 ml at 20C: 3.4
Vapour pressure, Pa at 20C: 40
Relative vapour density (air = 1): 3.2
Flash point: 70C c.c.
Auto-ignition temperature: 615C
Explosive limits, vol% in air: 1.2-11
Octanol/water partition coefficient as log Pow: 0.94
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms.
NOTES
Use of alcoholic beverages enhances the harmful effect. Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. The odour warning when the exposure limit value is exceeded is insufficient.
