A DuPont Subsidiary 40 Whitecap Drive North Kingstown, RI PHONE NUMBERS Product Information : /Outside US: Transport Emergency : CHEMTREC: /Outsdie US: Medical Emergency : /Outside US: COMPOSITION/INFORMATION ON INGREDIENTS Components Material CAS Number % Sodium Chlorite Water HAZARDS IDENTIFICATION Potential Health Effects EYE CONTACT may cause severe irritation and may cause burns. SKIN CONTACT may cause irritation and may cause burns. Prolonged contact may cause dermatitis. INHALATION may cause respiratory tract and mucous membrane irritation with sore throat, coughing and difficulty breathing. Intense exposures may result in delayed

2 Page 2 pulmonary edema. INGESTION may be harmful and may cause gastrointestinal irritation, abdominal pain, nausea, vomiting, diarrhea, burns and perforation of the digestive tract. Can be fatal if swallowed. NOTE: Upon contact with acids, organic materials, reducing agents or chlorine donors, this product will release CHLORINE DIOXIDE gas. Inhalation of chlorine dioxide can cause respiratory tract irritation, coughing, wheezing and burns of the mucous membranes. Inhalation of large amounts may lead to pulmonary edema and bronchitis. Prolonged or repeated inhalation of chlorine dioxide gas may cause chronic bronchitis or emphysema. Oxychlorine compounds have been shown to cause blood disorders in laboratory animals. Direct contact with chlorine dioxide causes eye and skin irritation and may cause burns. Chlorine dioxide is toxic by ingestion and may aggravate existing medical conditions such as asthma, bronchitis or any other respiratory ailment. Carcinogenicity Information None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen. FIRST AID MEASURES First Aid EYE CONTACT: Hold eye open and rinse slowly and gently with water for minutes. Remove contact lenses, if present, after the first 5 minutes, then continue rinsing eye. Call poison control center or doctor for treatement advice. SKIN CONTACT: Take off contaminated clothing. Rinse skin immediately with plenty of water for minutes. Call a poison control center or doctor for treatement advice. INHALATION: Move person to fresh air. If person is not breathing, call 911 or an ambulance, then give artificial respiration, preferably mouth-to-mouth, if possible. Call a poison control center or doctor for further treatment advice. INGESTION: Call poison control center or doctor immediately for treatment advice. Have person sip a glass of water if able to swallow. Do not induce vomiting unless told to do so by the poison control center or doctor. Do not give anything by mouth to an unconscious person.

FIRE FIGHTING MEASURES Flammable Properties Flash Point: Not Applicable Auto-Ignition: Not Applicable LEL: Not Applicable UEL: Not Applicable Dry Sodium Chlorite is a strong oxidizing agent. May increase flammability of combustible, organic or other readily oxidizable materials. Contact with acids, organic materials, reducing agents or chlorine donors will produce chlorine dioxide gas and heat. The lower explosive limit (LEL) for chlorine dioxide is 10% in air. Flush area with large amounts of air to keep the chlorine dioxide concentration below 10%. If allowed to dry, this product can be easily ignited by heat or friction. Do not allow this product to dry on cloth. Oxidation can cause a fire hazard. Extinguishing Media Water. Fire Fighting Instructions Evacuate personnel to a safe area. Wear self-contained breathing apparatus (SCBA) and full protective equipment. ACCIDENTAL RELEASE MEASURES Safeguards (Personnel) NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before proceeding with clean-up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean-up. Accidental Release Measures Flush with water to dilute. Do not allow contact with rags, paper or other oxidizable materials. For large spills, evacuate area, contain liquid and transfer to closed polyethylene drums. Prevent contact with oxidizers and

4 Page 4 acids. Do not allow liquid solution to dry. Keep out of water supply. Flush area with water after liquid is removed. HANDLING AND STORAGE Handling (Personnel) Do not breathe vapor or mist. Avoid contact with eyes, skin or clothing. Wash thoroughly after handling. Wash clothing after use. Handling (Physical Aspects) Do not allow solution to evaporate to dryness. Protect from heat, freezing and ultraviolet light. Keep container closed. Storage Store in a cool, dry location away from incompatible materials. Keep away from food and feed products. EXPOSURE CONTROLS/PERSONAL PROTECTION Engineering Controls Use only with adequate ventilation. Safety shower and eyewash facilities should be immediately accessible. Personal Protective Equipment EYE/FACE PROTECTION Wear coverall chemical splash goggles. Additionally, wear a face shield where the possibility exists for face contact due to splashing or spraying of material. RESPIRATORS Wear NIOSH approved respiratory protection as appropriate. PROTECTIVE CLOTHING Where there is potential for skin contact have available and wear as appropriate impervious gloves, apron, pants, jacket, hood and boots. Exposure Guidelines Exposure Limits ADOX(R) 3125/8125 PEL (OSHA) : None Established

5 Page 5 TLV (ACGIH) : None Established Exposure Guideline Comments Upon exposure to acid, this product releases chlorine dioxide. The OSHA PEL, as well as the ACGIH TLV, for chlorine dioxide is 0.1 ppm, 0.3 ppm STEL. PHYSICAL AND CHEMICAL PROPERTIES Physical Data Boiling Point: ~106 degrees C Freezing Point: ~-18 degrees C Vapor Pressure: ~21 mm/hg Solubility in Water: Miscible ph: 12.0 to 13 Odor: Faint Bleach Form: Liquid Color: Pale Green Specific Gravity: g/cc at 20 degrees C (H2O = 1) Density: ~10.05 STABILITY AND REACTIVITY Chemical Stability Stable. Incompatibility with Other Materials Contact with acids, organic materials, reducing agents and chlorine donors will release toxic chlorine dioxide. Decomposition Decomposes with heat. Thermal decomposition will produce toxic chlorine dioxide gas. Polymerization Polymerization will not occur. TOXICOLOGICAL INFORMATION Animal Data Sodium Chlorite:
