  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, foam, powder, carbon dioxide.   

 PREVENT GENERATION OF MISTS!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Nausea. Muscle twitching. Sweating. Pupillary constriction. Muscle cramps. Excessive salivation. Vomiting. Diarrhoea. Laboured breathing. Convulsions. Cough. Blurred vision. Unconsciousness.  Use ventilation, 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 immediately 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.

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

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

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


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to bees. 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 solvent(s) also consult the card(s) (ICSC) of the solvent(s).
