  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION 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.      Use alcohol-resistant foam, dry sand, powder, carbon dioxide.   

 PREVENT DISPERSION OF DUST! STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Burning sensation. Convulsions. Cough. Laboured breathing. Shortness of breath. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness. Pain.  Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Cough.  Do not eat, drink, or smoke during work. Wash hands before eating.  Do NOT induce vomiting. Refer for medical attention .

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the peripheral nervous system. This may result in convulsions and ataxia. 

Inhalation risk
 

Effects of long-term or repeated exposure
 


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 mammals and bees. The substance may cause long-term effects in the aquatic environment. 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
Liquid formulation can be aspired into the lungs resulting in chemical pneumonitis, showing tremors and convultions.
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s).
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
The recommendations on this Card also apply to cyhalothrin.
