EXPOSURE
STRICT HYGIENE!

INHALATION Cough. Sore throat.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest.
SKIN MAY BE ABSORBED! Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes.

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.
Rest.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Do NOT wash away into sewer. 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).

PHYSICAL STATE; APPEARANCE:
YELLOW CRYSTALS. TURNS DEEP GREEN ON EXPOSURE TO LIGHT.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating and on burning producing toxic and irritating fumes including nitrogen oxides and sulfur oxides).

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 5 mg/m3 (as TWA) (skin) (ACGIH 1991-1992).


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

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed, especially, if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin, the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization as well as photosensitization.
