TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).

EXPOSURE
AVOID ALL CONTACT!

 •INHALATION
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.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION
Do not eat, drink, or smoke during work. Wash hands before eating.
Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles.) Do NOT let this chemical enter the environment.
Separated from oxidants.

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. The substance decomposes on burning producing toxic and corrosive fumes .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: A4; (ACGIH 2003).
MAK:
Carcinogen category: 3B;
(DFG 2002).
OSHA PEL: none
NIOSH REL: Ca* See Appendix A *Note: Since metabolized to beta-Naphthylamine.
NIOSH IDLH: Ca N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is mildly irritating to the eyes .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.

ENVIRONMENTAL
DATA
Environmental Hazard placard Bioaccumulation of this chemical may occur in fish.
N O T E S
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 2-Naphthylamine. Do NOT take working clothes home.
