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, foam, powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Dizziness. Nausea. Muscle twitching. Sweating. Pupillary constriction, muscle cramp, excessive salivation. Vomiting. Diarrhoea. Laboured breathing. Cough. Blurred vision.  Use local exhaust or breathing protection.  Refer immediately for medical attention. 
Skin See Inhalation.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   Wear safety spectacles or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion See Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer immediately for medical attention. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING

Physical dangers
 

Chemical dangers
Decomposes on heating or on burning. This produces toxic and corrosive fumes including nitrogen oxides and sulfur oxides. 

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

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

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

Effects of short-term exposure
Cholinesterase inhibition. The substance may cause effects on the nervous system. This may result in respiratory depression. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds. 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
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvents also consult the ICSCs of these materials.
