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 nitric acid.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Above 85°C explosive vapour/air mixtures may be formed.
Above 85°C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
INHALATION Blue lips or finger nails. Blue skin. Confusion. Dizziness. Headache. Shortness of breath. Weakness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
SKIN MAY BE ABSORBED! Redness. Blue lips or fingernails. Blue skin (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.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION Blue lips or fingernails. Blue skin. Dizziness. Headache. Laboured breathing (further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus).
Separated from strong oxidants, strong acids, food and feedstuffs. Cool. Dry. Well closed. Ventilation along the floor.
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID, TURNS REDDISH-BROWN ON EXPOSURE TO AIR AND LIGHT.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides. Reacts with strong oxidants, especially nitric acid.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 2 ppm; 8.8 mg/m3 (as TWA) A2 (skin) (ACGIH 1994-1995.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin, and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the skin. The substance may cause effects on the blood, bladder and kidneys , resulting in tissue lesions, impaired functions and formation of methaemoglobin. Exposure to high concentrations may result in damage to kidneys and bladder. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood , resulting in the formation of methaemoglobin (see Notes). This substance is possibly carcinogenic to humans.

ENVIRONMENTAL
DATA
 The substance is harmful to aquatic organisms.
N O T E S
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. Also consult ICSC # 0342, meta-Toluidine and 0343, para-Toluidine.
