N-2-Naphthylaniline
CAS #: 135-88-6
UN #: 3077
EC Number: 205-223-9

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Finely dispersed particles form explosive mixtures in air.  NO open flames.  Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).  Use water spray, powder, foam, carbon dioxide.   

 AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use closed system, local exhaust or breathing protection.  Fresh air, rest. Seek medical attention if you feel unwell. 
Skin Redness.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.  Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance may be irritating to the skin and eyes. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: A4 (not classifiable as a human carcinogen).
MAK: skin absorption (H); sensitization of skin (SH); carcinogen category: 1; germ cell mutagen group: 3A 

ENVIRONMENT
The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. The substance may cause long-term effects in the aquatic environment. 

NOTES
Commercial Phenyl-beta-naphthylamine may contain beta-Naphthylamine as an impurity.
See ICSC 610.
Phenyl-beta-naphthylamine is also metabolised in the body to beta-Naphthylamine which is a bladder carcinogen.
Do NOT take working clothes home.
