FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

 •INHALATION Blue lips or finger nails. Blue skin. Confusion. Dizziness. Headache. Shortness of breath. Weakness.
Local exhaust or breathing protection.
Fresh air, rest. 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.
 •EYES Redness. Pain.
Safety spectacles, 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 Blue lips or fingernails. Blue skin. Dizziness. Headache. Nausea.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS , WITH CHARACTERISTIC ODOUR. TURNS RED ON EXPOSURE TO AIR, LIGHT AND MOISTURE.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing nitrogen oxides and carbon monoxide . The substance is a weak base.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.
OSHA PEL: 1910.1004 See Appendix B
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Ca N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin 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 and the skin. The substance may cause effects on the blood , resulting in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
See Notes.

ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is harmful to aquatic organisms. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
N O T E S
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. Bladder cancers reported after occupational exposure to 1-naphthylamine may be due to contamination with 2-naphthylamine which is a human carcinogen.
