TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE 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. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!   
Inhalation See Notes.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. See Notes. 
Skin See Notes.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Notes.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rest. Refer for medical attention . See Notes. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT wash away into sewer. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

EMERGENCY RESPONSE SAFE STORAGE
  Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-WHITE CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic and irritating fumes including nitrogen oxides, phosphorus oxides and sulfur oxides. Attacks copper. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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

Effects of short-term exposure
The substance may cause effects on the nervous system. This may result in convulsions and respiratory failure. Cholinesterase inhibition. Exposure could cause death. The effects may be delayed. Medical observation is indicated. See Notes. 

Effects of long-term or repeated exposure
Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms. See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 34°C
Relative density (water = 1): 1.2
Solubility in water, g/100ml at 20°C: 0.0025
Vapour pressure, Pa at 20°C: <0.001
Octanol/water partition coefficient as log Pow: 4.22  
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to its persistence in soil. 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
No specific data on health hazard of this compound were available but many organophosphates are cholinesterase inhibitors (for instance, see ICSC 0172 on Malathion).
If the substance is formulated with solvents also consult the ICSCs of these materials.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Betamec, Betasan, Disan, Exporsan, Prefar, Pre-san are trade names.
Card has been partly updated in October 2005.
