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, foam, powder, 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		STRICT HYGIENE!	IN ALL CASES CONSULT A DOCTOR!
•INHALATION	Blue lips or finger nails. Blue skin. Confusion. Dizziness. Headache. Shortness of breath. Weakness. Convulsions. Nausea. Unconsciousness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer immediately for medical attention.
•SKIN	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.	Safety goggles.	Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
•INGESTION	Blue lips or fingernails. Blue skin. Dizziness. Headache. Laboured breathing (Further see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Refer immediately for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID TURNS DARK ON EXPOSURE TO AIR AND LIGHT.

PHYSICAL DANGERS:
As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides . Reacts with strong oxidants and strong acids . Attacks some forms of plastic .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA (skin) A4 (not classifiable as a human carcinogen); BEI issued (ACGIH 2009).
MAK not established.
OSHA PEL†: none
NIOSH REL: See Appendix D
NIOSH IDLH: N.D. See: IDLH INDEX

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 is irritating to the eyes and is mildly irritating to the skin . The substance may cause effects on the blood , resulting in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
L for rats/oral/14 days is 30 mg/kg bw

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment.

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. Do NOT take working clothes home. See also ICSC 0341 o-Toluidine and 0343 p-Toluidine.
