SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Many reactions may cause fire or explosion. See Notes.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.

Combat fire from a sheltered position.
 
EXPOSURE
STRICT HYGIENE!

INHALATION

Headache. Faintness. Vertigo. Weakness.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN MAY BE ABSORBED! (further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
EYES
Safety goggles, or eye protection in combination with breathing protection if powder.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION (further see Inhalation).

Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!).
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus).
Separated from combustible and reducing substances, food and feedstuffs. Keep in a well-ventilated room.
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
YELLOWISH CRYSTALS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic gases (nitrogen oxides, hydrochloric acid, phosgene and chlorine). The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts with many substances causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV (as TWA): 0.1 ppm; 0.64 mg/m3 (skin) (ACGIH 1991-1992).


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the blood.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood , resulting in forming of methaemoglobin (see Notes).
