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 oxidizing agents.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Risk of fire and explosion on contact with oxidizing agents.     
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Blue lips, fingernails and skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconciousness.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. See Notes. 
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.  Wear 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 refer for medical attention. 
Ingestion 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. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
HYGROSCOPIC WHITE CRYSTALS. TURNS DARK ON EXPOSURE TO AIR AND LIGHT. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on contact with acids. This produces toxic and corrosive fumes including aniline, nitrogen oxides and hydrogen chloride. Reacts violently with oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV: 2ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: 2 ppm, 7.7 mg/m³; Carcinogen category: 4; Peak limitation category: II(2); Pregnancy risk group: C; Skin absorption (H); Sensitization of skin (SH); BAT issued; (DFG 2008). 

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the blood. This may result in formation of methaemoglobin. Exposure at high levels could cause 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. This may result in formation of methaemoglobin. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 245°C

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 suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Also consult ICSC 0011 Aniline.
