TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.   In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF (PREGNANT) WOMEN!  
Inhalation Cough. Shortness of breath. Sore throat. Nose bleeds. Local exhaust or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated.
Skin Dry skin. Redness. Pain. Protective gloves. First rinse with plenty of water, then remove contaminated clothes and rinse again.
Eyes Redness. Pain. 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 Abdominal pain. Diarrhoea. Headache. Nausea. Vomiting. Weakness. Convulsions. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL PACKAGING & LABELLING
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).  

EMERGENCY RESPONSE SAFE STORAGE
  Separated from acids.

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALS OR CRYSTALLINE POWDER.

Chemical dangers
The substance is a weak base.

Occupational exposure limits
TLV: 5 mg/m³ (ACGIH 1996).
MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of short-term exposure
The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system, kidneys and liver, when ingested. The effects may be delayed.

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
