  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Finely dispersed particles form explosive mixtures in air.  NO open flames.  PREVENT DISPERSION OF DUST.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion No acute symptoms expected.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. 

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. If appropriate, moisten first to prevent dusting. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
WHITE CRYSTALLINE POWDER WITH CHARACTERISTIC ODOUR. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Decomposes on heating. This produces toxic fumes including nitrogen oxides. Reacts with strong oxidants and peroxides. This generates fire and explosion hazard. 

Formula: C14H18N4O3
Molecular mass: 290.3
Melting point: No melting point; decomposes at 140°C
Solubility in water, mg/l at 25°C: 3.8 (very poor)
Vapour pressure, Pa at 25°C: (negligible)
Density: 0.38 g/cm³
Octanol/water partition coefficient as log Pow: 2.12
Explosive limits, vol% in air: 0.05 - ?
Auto-ignition temperature: 220°C  


EXPOSURE & HEALTH EFFECTS

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

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

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Animal tests show that this substance possibly causes toxic effects upon human reproduction. May cause genetic damage in humans. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: (inhalable fraction): 1 mg/m3, as TWA; (SEN).
MAK: sensitization of skin (SH); germ cell mutagen group: 3A 

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
Do NOT take working clothes home.
If the substance is formulated with solvents also consult the ICSCs of these materials.
