Gives off irritating or toxic fumes (or gases) in a fire. Alcohol-resistant foam, powder, carbon dioxide. 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. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES 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 take to a doctor.  •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 STORAGE PACKAGING & LABELLING Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Personal protection: complete protective clothing including self-contained breathing apparatus. Separated from food and feedstuffs . Keep in a well-ventilated room. Do not transport with food and feedstuffs. Severe marine pollutant. UN Hazard Class: 6.1 UN Packing Group: III SEE IMPORTANT INFORMATION ON BACK ICSC: 1248 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards SULPROFOS ICSC: 1248 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO BROWN OILY LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes including phosphorus oxides , sulfur oxides . OCCUPATIONAL EXPOSURE LIMITS: TLV: 1 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004). OSHA PEL†: none NIOSH REL: TWA 1 mg/m3 NIOSH IDLH: N.D. See: IDLH INDEX 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 , 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 20°C: <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. N O T E S 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.
