EXPOSURE
AVOID ALL CONTACT!

Inhalation Blue lips or finger nails. Blue skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin MAY BE ABSORBED! Redness
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, 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 (See Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Rest. Refer for medical attention.

XYLIDINE (MIXED ISOMERS) ICSC: 0600
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
PALE YELLOW TO BROWN LIQUID, WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes. Reacts violently with strong oxidants. Reacts with hypochlorites forming explosive chloroamines. Attacks plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.5 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 3A; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. 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 kidneys, liver. This substance is possibly carcinogenic to humans.
PHYSICAL PROPERTIES
Boiling point: 213-226C
Relative density (water = 1): 0.97-0.99
Solubility in water: poor
Vapour pressure, Pa at 20C: <20
Relative vapour density (air = 1): 4.2
Flash point: 96C c.c.
Explosive limits, vol% in air: 1.5-?
Octanol/water partition coefficient as log Pow: 1.8 (estimated)
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Commercial xylidine is a mixture of isomers where the 2,4-, 2,5- and 2,6-isomers dominate. The various isomers of Xylidine have different physical properties. See ICSC 1519 2,6-Xylidine and 1562 2,4-Xylidine. 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. Acid Leather Brown 2G, Acid Orange 24, 11460 Brown, Resorcine Brown J are trade names. Card has been partly updated in October 2005. See section Occupational Exposure Limits.
