TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use powder, alcohol-resistant foam, water spray, carbon dioxide. 
EXPLOSION Risk of fire and explosion on contact with: See Chemical Dangers.     
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety goggles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & 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. Then store and dispose of according to local regulations.

GHS Classification
Signal: Warning
Causes mild skin irritation
Causes damage to the liver and the kidneys through prolonged or repeated exposure if swallowed
Harmful to aquatic life 
cancer;health haz

EMERGENCY RESPONSE SAFE STORAGE
  Separated from strong oxidants. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALS WITH FLOWERY ODOR. 

Physical dangers
No data. 

Chemical dangers
On combustion, forms toxic gases. Reacts with strong oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV not established.
MAK (not established):. 

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

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

Effects of short-term exposure
The substance is mildly irritating to the skin. 

Effects of long-term or repeated exposure
The substance may have effects on the liver and kidneys, resulting in impaired functions. Tumours have been detected in experimental animals but may not be relevant to humans.
