  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames.    Use water spray, powder, foam, carbon dioxide.   

 PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Abdominal pain. Diarrhoea. Headache. Sweating. Nausea. Shortness of breath. Vomiting. Weakness.  Use local exhaust.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. See Notes. 
Skin MAY BE ABSORBED! See Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . See Notes.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes including nitrogen oxides. Reacts slowly with water. This produces harmful Dinoseb. 

Formula: C15H18N2O6
Molecular mass: 322.3
Melting point: 66-67°C
Relative density (water = 1): 1.2
Solubility in water: none
Vapour pressure, Pa at 60°C: 0.013  


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance may cause effects on the metabolism. This may result in high body temperature and sweating. The effects may be delayed. Medical observation is indicated. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. 

NOTES
Binapacryl is the dimethyl acrylic ester of harmful Dinoseb.
It is metabolized to form Dinoseb.
Toxicity is attributed to Dinoseb.
Use all available methods for reducing body temperature.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
See ICSCs 0149 and 0882.
