  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion if formulations contain flammable/explosive solvents.      In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Sweating. Pupillary constriction, muscle cramp, excessive salivation. Dizziness. Vomiting. Laboured breathing. Unconsciousness.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. See Notes. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal cramps. Diarrhoea. Headache. Nausea. Vomiting. Weakness. Further see Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Give a slurry of activated charcoal in water to drink. Refer for medical attention . See Notes. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

EXPOSURE & HEALTH EFFECTS

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

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

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


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.1 mg/m3, as TWA; A4 (not classifiable as a human carcinogen); BEI issued 

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to soil organisms, bees and 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
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Do NOT take working clothes home.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s).
