TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.    Use alcohol-resistant foam, powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Incoordination. Dizziness. Headache. Laboured breathing. Nausea. Unconciousness. Vomiting. Pupillary constriction, muscle cramp, excessive salivation.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   Wear face shield 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. Nausea. Vomiting. Pupillary constriction. Muscle cramps. Excessive salivation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-BROWN OILY LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic fumes including phosphorus oxides and sulfur oxides. 

Occupational exposure limits
TLV: 1mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004). 

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. 

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. 

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


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Relative density (water = 1): 1.20
Solubility in water: poor
Vapour pressure, Pa at 20°C: <0.0001  
This substance may be hazardous to the environment. Special attention should be given to fish and wildlife. 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.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
NTN 9306, BAY-NTN9306, Bolstar, Helothion are trade names.
Card has been partly updated in April 2005.
