MATERIAL SAFETY DATA SHEET Product name: Attack SECTION V SUPPLEMENTAL HEALTH INFORMATION Chronic overexposures found to produce liver and kidney toxic effects in experimental animals. CARCINOGENICITY Component - 1: has been evaluated for possible cancer causing effects in laboratory animals. Inhalation studies at concentrations of 2000, and 4000ppm increased the incidence of malignant liver and lung tumors in mice. Inhalation studies of rats have shown increased the incidence of benign mammary gland tumors in female rats at concentrations of 500pmm. And above and increases the incidence of benign mammary gland tumors in male rats at concentrations of 1500pmm and above. Rats exposed to 50 and 200 pmm via inhalation showed no increased incidence of tumors. Mice and rats; exposed by ingestion at levels up to 250 mgkg/day lifetime and hamsters exposed via inhalation to concentrations up to 3500 pmm lifetime did not show an increased incidence of tumors. (IARC) has concluded that with respect to dichloromethane and dimethylformamide, there is sufficient evidence of the carcinogenicity to experimental animals and inadequate evidence of the carcinogenicity to humans, resulting in a classification as a 2b animal carcinogen. The (NTP) has identified dichloromethane as an animal carcinogen. The state of California has listed the dichloromethane as a chemical known to the state to cause cancer. REPRODUCTIVE TOXICITY Tests have been conducted to evaluate the adverse effects dichloromethane may have on reproduction and offspring of laboratory animals. The results indicate dichloromethane does not cause birth defects in laboratory animals. The test results for dimethylformamide is not available. SECTION VI EMPLOYEE PROTECTION RESPIRATORY PROTECTION Avoid breathing vapors/mists. Vapor concentration that exceed 50ppm, an NISOH-approved full-face respirator with organic vapor cartridges is acceptable. Use either a full-face, self-contained breathing apparatus or air line respirator with full facepiece for vapor concentrations above 1000 ppm and for spills and or emergencies. PROTECTIVE CLOTHING Wear chemical goggles, full-length face shield. Avoid contact with skin and clothing. Wear chemical-resist ant gloves such as vitron or butyl. Solvent-resistant boots, apron and protective clothing. ADDITIONAL PROTECTIVE MEASURES Use ventilation as required to control vapor concentrations to maintain exposure levels below 50ppm (twa) to determine exposure levels, monitoring should be performed regularly. Eye wash fountains and safety shower should be available for emergency use.

Special fire fighting procedures and precautions Material will not burn unless preheated. Do not enter confined fire space without full bunker gear (helmet with face shield, bunker coats, gloves and rubber boots), including a positive pressure NISOH approved self-contained breathing apparatus. Unusual fire and explosion hazards Concentrated vapors can be ignited by high intensity ignition source. Firefighters should wear self-contained positive pressure breathing apparatus due to thermal decomposition products and avoid skin contact SECTION IX REACTIVITY Stability: Stable Hazardous polymerization: Will not occur Condition and material to avoid: Avoid heat, flame and contact with electric arcs, or other hot surfaces which can cause thermal decomposition. Avoid strong alkalies, oxygen, nitrogen peroxide, sodium, potassium, polyhalogenated compounds and other oxidizers and reactive metals. Hazardous decomposition products Hydrogen chloride, phosgene, chlorine, may release dimethylamine and carbon monoxide. Additional protective measures Use ventilation as required to control vapor concentrations. Eye wash fountains and safety shower Should be available for emergency use. . SECTION X STORAGE AND HANDLING PRECAUTIONS Store labeled, sealed containers in a cool, dry, well ventilated area out of sunlight. Prevent water or moist air from entering containers. Do not cut or weld on empty or full containers. Aluminum equipment should not be used for storage and/or transfer. Vapors are heavier than air and will collect in low area. Do not remove or deface label. Do not reuse container. MATERIAL SAFETY DATA SHEET Product name: Attack SECTION XI SPILL OR LEAK PROCEDURES Evacuate area, ventilate, and avoid breathing vapors. Dike area to contain spill. If spill occur indoors, turn off air conditioning and/or heating system, to prevent vapors from contaminating entire building. Clean up area by mopping or with absorbent material and place in closed containers for disposal. Prevent entry into sewers and waterways. Small spills Soak up residue with an absorbent such as clay, sand or other suitable material; dispose of properly. Consult federal, state, or local disposal authorities for approved procedures. SECTION XII SPECIAL PRECAUTION Warning. Extremely irritating to the eyes. May cause skin and respiratory tract irritation and sensitization. Containers, even those that have been emptied, can contain hazardous product residues. Wash with soap and water before eating, drinking, smoking, applying cosmetic, or using toilet facilities. Launder contaminated clothing before reuse. Contaminated leather articles including shoes cannot be decontaminated and should be destroyed. Fumes and vapors from the thermal and chemical decompositions vary widely in composition and toxicity. Do not breath fumes. Use a NISOH-approved respirator as required to prevent over exposure. The "skin" notation indicates that the liquid and vapor can penetrate skin and mucous membranes. Therefore, control of inhalation alone may not be sufficient to prevent an excessive dose. Store in a cool, dry place with adequate ventilation. Keep away from open flames and high temperatures. Misuse of empty containers can be hazardous. Cutting or welding of empty containers might cause fire, explosion or toxic fumes from residues. Do not pressurize containers to empty them.
