  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. See Chemical dangers Gives off irritating or toxic fumes (or gases) in a fire.    NO contact with combustible substances or incompatible substances. See Chemical Dangers.    Use water in large amounts.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Nausea.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents.

ZINC NITRATE ICSC: 1206
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS CRYSTALS OR POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes including nitrogen oxides and zinc oxides. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. Reacts violently with carbon, copper, metal sulfides, phosphorus and sulfur. This generates fire or explosion hazard. 

Formula: N2O6Zn / Zn(NO3)2
Molecular mass: 189.4
Melting point: ~110°C
Relative density (water = 1): 2.07 (hexahydrate)
Solubility in water, g/100ml at 20°C: 200 (very good) 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
MAK: (as Zn, respirable fraction): 0.1 mg/m3; peak limitation category: I(4); (as Zn, inhalable fraction): 2 mg/m3; peak limitation category: I(2); pregnancy risk group: C; (DFG 2016) 

ENVIRONMENT
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Other melting points: 45.5°C (trihydrate); 36.4°C (hexahydrate).
