Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Cough. Sore throat. Wheezing. Ventilation (not if powder), local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN MAY BE ABSORBED! Redness. Rash. Blisters. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. Pain. Itching. Face shield or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Burning sensation. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P3 filter respirator for toxic particles. Provision to contain effluent from fire extinguishing. Separated from strong bases, food and feedstuffs . Do not transport with food and feedstuffs.

International Chemical Safety Cards CAPTAFOL ICSC: 0119 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALLINE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic and corrosive fumesincludinghydrogen chloride (see ICSC 0163), nitrogen oxides,sulfur oxides. Reacts violently with bases causing fire and explosion hazard. Attacks some metals. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 mg/m³ as TWA; (skin); A4 (not classifiable as a human carcinogen); (ACGIH 2004). MAK not established. OSHA PEL: none NIOSH REL: Ca TWA 0.1 mg/m3 skin See Appendix A NIOSH IDLH: Potential occupational carcinogen No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization, allergic conjunctivitis. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the l liver kidneys . This substance is probably carcinogenic to humans. PHYSICAL PROPERTIES Melting point: 160-161°C Solubility in water: none Relative vapour density (air = 1): 12 Relative density of the vapour/air-mixture at 20°C (air = 1): 1 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to aquatic organisms and soil organisms. The substance may cause long-term effects in the aquatic environment. N O T E S Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Difolatan, Folcid, Foltaf, Haipen, Merpafol, Ortho 5865, Sabsoir, Sanspor, Santar, Sulfenimede and Nalco 7046 are trade names. Card has been partly updated in April 2005.
