PREVENTION

FIRST AID/
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! AVOID EXPOSURE OF (PREGNANT) WOMEN!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Unconsciousness.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
•EYES Redness. Pain.
Face shield 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 Nausea. Vomiting. (See Inhalation).
Do not eat, drink, or smoke during work.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
ALMOST ODOURLESS, COLOURLESS CRYSTALS, PELLETS OR WHITE GRANULAR POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes ( nitrogen oxides ).

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: skin absorption (H);
Carcinogen category: 2; Germ cell mutagen group: 3A;
(DFG 2004).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol 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 central nervous system and liver .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the bone marrow, brain, kidneys, eyes. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
