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 96°C explosive vapour/air mixtures may be formed.	Above 96°C use a closed system, ventilation.

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.

N O T E S

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 indicated. 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.
