PHENYL-beta-NAPHTHYLAMINE	ICSC: 0542 (August 2003)
2-Naphthylamine, N-phenyl- N-2-Naphthylaniline

CAS #: 135-88-6

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 local exhaust or breathing protection.	Fresh air, rest.
Skin		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.	Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Separated from oxidants.
PACKAGING

PHENYL-beta-NAPHTHYLAMINE

ICSC: 0542

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE-TO-GREY SOLID IN VARIOUS FORMS. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. Chemical dangers Reacts with oxidants. Decomposes on burning. This produces toxic and corrosive fumes.	Formula: C₁₆H₁₃N / C₁₀H₇NHC₆H₅ Molecular mass: 219.29 Boiling point: 395.5°C Melting point: 108°C Density: 1.2 g/cm³ Solubility in water at 25°C: none Octanol/water partition coefficient as log Pow: 4.38

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure The substance is mildly irritating to the eyes.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is mildly irritating to the eyes.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.

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
Bioaccumulation of this chemical may occur in fish.

NOTES
Commercial Phenyl-beta-naphthylamine may contain beta-Naphthylamine as an impurity. Phenyl-beta-naphthylamine is also metabolised in the body to beta-Naphthylamine which is a bladder carcinogen. See ICSC 0610. Do NOT take working clothes home. TLV Note: Exposure by all routes should be carefully controlled to levels as low as possible.
