SECTION 4: First aid measures General advice : Move out of dangerous area. Consult a physician. Show this material safety data sheet to the doctor in attendance. Material may produce a serious, potentially fatal pneumonia if swallowed or vomited. SAFETY DATA SHEET Dimethyl Disulfide Version Revision Date 2018-01-04 SDS Number:100000013403 4/15 If inhaled : Call a physician or poison control center immediately. If unconscious, place in recovery position and seek medical advice.

6 In case of skin contact : If on skin, rinse well with water. If on clothes, remove clothes. In case of eye contact : Immediately flush eye(s) with plenty of water. Remove contact lenses. Protect unharmed eye. Keep eye wide open while rinsing. If eye irritation persists, consult a specialist. If swallowed : Keep respiratory tract clear. Never give anything by mouth to an unconscious person. If symptoms persist, call a physician. Take victim immediately to hospital. SECTION 5: Firefighting measures Flash point : 15 C (59 F) Method: closed cup Autoignition temperature : No data available Suitable extinguishing media : Alcohol-resistant foam. Carbon dioxide (CO2). Dry chemical. Unsuitable extinguishing media : High volume water jet. Specific hazards during fire fighting : Do not allow run-off from fire fighting to enter drains or water courses.

7 Special protective equipment for fire-fighters : Wear self-contained breathing apparatus for firefighting if necessary. Further information : Collect contaminated fire extinguishing water separately. This must not be discharged into drains. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations. For safety reasons in case of fire, cans should be stored separately in closed containments. Use a water spray to cool fully closed containers. Fire and explosion protection : Do not spray on an open flame or any other incandescent material. Take necessary action to avoid static electricity discharge (which might cause ignition of organic vapors). Use only explosion-proof equipment. Keep away from open flames, hot surfaces and sources of ignition. Hazardous decomposition products : Hydrogen Sulfide.

8 Sulfur oxides. SECTION 6: Accidental release measures Personal precautions : Use personal protective equipment. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to SAFETY DATA SHEET Dimethyl Disulfide Version Revision Date 2018-01-04 SDS Number:100000013403 5/15 form explosive concentrations. Vapors can accumulate in low areas. Environmental precautions : Prevent product from entering drains. Prevent further leakage or spillage if safe to do so. If the product contaminates rivers and lakes or drains inform respective authorities. Methods for cleaning up : Contain spillage, and then collect with non-combustible absorbent material, ( sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / national regulations (see section 13).

9 SECTION 7: Handling and storage Handling Advice on safe handling : In case of an accident, this substance must be handled under Strictly Controlled Conditions (SCC) in accordance with REACH regulation Article 18(4) for transported isolated intermediates. Avoid formation of aerosol. Do not breathe vapors/dust. Avoid contact with skin and eyes. For personal protection see section 8. Smoking, eating and drinking should be prohibited in the application area. Take precautionary measures against static discharges. Provide sufficient air exchange and/or exhaust in work rooms. Open drum carefully as content may be under pressure. Dispose of rinse water in accordance with local and national regulations. Advice on protection against fire and explosion : Do not spray on an open flame or any other incandescent material. Take necessary action to avoid static electricity discharge (which might cause ignition of organic vapors).

10 Use only explosion-proof equipment. Keep away from open flames, hot surfaces and sources of ignition. Storage Requirements for storage areas and containers : Prevent unauthorized access. No smoking. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Observe label precautions. Electrical installations / working materials must comply with the technological safety standards.
