EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Blue lips or finger nails. Blue skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconsciousness.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN MAY BE ABSORBED! Redness. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
 •EYES Redness. Pain.
Safety goggles, 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 take to a doctor.
 •INGESTION (See Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS, TURNS RED ON EXPOSURE TO AIR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes including nitrogen oxides . Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2008).
MAK: skin absorption (H); sensitization of skin (Sh);
Carcinogen category: 3B;
(DFG 2009).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C ; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin . The substance may cause effects on the kidneys and blood , resulting in renal failure and formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys , resulting in renal failure.
