EXPLOSION


EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Ataxia. Dizziness. Headache. Laboured breathing. Nausea. Unconsciousness. Vomiting. Pupillary constriction, muscle cramp, excessive salivation.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin MAY BE ABSORBED! (Further see Inhalation).
Protective gloves. Protective clothing.

SULPROFOS ICSC: 1248
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO BROWN OILY LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including phosphorus oxides, sulfur oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 1 mg/m 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 20C 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, resulting in convulsions, respiratory failure. Cholinesterase inhibitor. Exposure may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
PHYSICAL PROPERTIES
Relative density (water = 1): 1.20
Solubility in water: poor
Vapour pressure, Pa at 20C: <0.0001
ENVIRONMENTAL DATA
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 given to avoid any additional release, e.g. 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. See sections Occupational Exposure Limits, Emergency Response.
