First-aid measures

Inhalation: Remove victim from area of exposure to fresh air - avoid becoming a casualty. If symptoms of carbon disulfide exposure developed (headache, dizziness, fatigue or excitement), take proper precautions to ensure your own safety before attempting rescue. Remove contaminated clothing and loosen remaining clothing. Allow patient to assume most comfortable position and keep warm. Apply artificial respiration if breathing stopped. Give oxygen if breathing is difficult. Seek immediate medical advice.Skin contact: Remove contaminated clothing, shoes and leather goods.. Wash affected area with soap and plenty of water gently flowing for at least 20 minutes. If swelling, redness, blistering or irritation occurs seek medical assistance.Eye contact: DUSTS: Donot allow victim to rub eyes. For few minutes water the eyes, if the dust does not dislodge, flush with lukewarm , gfently flowing water for about 5 minutes, while holding the eyes open.SOLUTION: Immediately flush eyes with plenty of water holding eyelids apart. Continue flushing until advised to stop by the Poison Information Center,or for at least 15 minutes Swallowed: Rinse mouth with water. Give plenty of water to drink. Do not give anything by mouth if person is losing consciousness. If vomiting occurs give father water. Do not induce vomiting. Seek immediate medical assistance.

Fire-fighting measures

Flammability : Solid xanthates are reactive flammable materials. Xanthate dust are COMBUSTIBLE DASTS. The dry powder of xanthates can form an explosive dust-air mixture, which can be ignited by a spark or flame. Contact with small amounts of water or water vapour will generate very flammable carbon disulfide Although xanthate solutions are not flammable mixtures, they decompose on standing/heating to toxic and highly flammable compounds such as alcohol and carbon disulfide. Combustion products may also include carbon monoxide and sulfur oxides.Eliminate all ignition sources including cigarettes, open flames, spark producing switches/tools, pilot lights, heaters, naked lights, mobile phones etc. when handling. Earth containers when dispensing fluids. Special precautions should be observed during: pumping xanthate solutions, draining and cleaning tanks, performing maintenance work on tanks and pipelines. All employed engines have to be explosion-proof. Fire and explosion: Evacuate area and contact emergency service. Toxic gases may be evolved in a fire situation. Remain upwind and notify those downwind of the hazard. Wear full protective equipment including Self contained Breathing Apparatus when combating fire. Use water-fog to cool intact containers and nearby storage areas. Fire hydrants with attendant equipment should be situated close proximity of plant, recommended. Use water in flooding quantities as a spray to keep fire-exposed containers, drums or tanks cool and absorb heat to help prevent rupture. Take care not to get water inside the containers.Extinguishing media: Carbon dioxide, dry chemical powder, or appropriate foam , recommended by manufactures.

Accidental release measures

Emergency procedures: Shut of all possible sources of ignition. Use clean, non-sparking tools and equipment. Clean area of all unprotected personnel. Avoid skin/eye contact or inhalation.Personnel involved in the clean should wear full protective clothing. In case of wet spill, self contained breathing apparatus should be used. In a minor spill situation use a respirator with an organic vapor cartridge. Ensure that surfaces are not slippery before waking on them.Spillage: This product is highly toxic to aquatic organisms. Do not allow the substance to enter drains, waterways or river systems.Spills should be contained by dyke. Removed material reclaimed by mechanical means and contaminated soil and absorbents disposed of in accordance with local regulations. In the event of a roadside spill, contaminated soil should be collected where possible and disposed of in accordance with government regulations.Clean spills with minimal amount of water if possible and dispose of as liquid waste.

Handling and storage

Precaution for safe handling: Solid xanthates are reactive and flammable materials, they decomposes reacting with water to form very toxic and extremely flammable carbon disulfide vapour. The dry powder is combustible dust. Ensure an eye bath and safety shower are available and ready for use. Observed good personal hygiene practices and recommended procedures. Wash thoroughly hands after handling before eating. Prohibit eating, drinking and smoking in contaminated area.Take precautionary measures against static discharges by bonding and grounding equipment. Maintain the pH of solution of xanthates in the range of 10 - 11.Personnel must be trained and periodically retrained in the hazards associated with xanthate and the required control procedures implemented.Storage: Solution of xanthates.To reduce build-up of carbon disulfide during storage xanthates solution should be kept below 180C and the pH in the range 10 - 11. Carbon steel is suitable for the fabrication of mixing and storage tanks. Tanks should be well ventilated and drained from lowest point to allow continuous removal of any accumulated carbon disulfide.Store away from sources of heat or ignition.Solid xanthates. Store in a cool, dry, well ventilated area out of direct sunlight and away from heat and ignition sources. Any ignition sources should not be allowed around indoor or outdoor storage areas. Prevent accidental contact with water. Ground floor storage is recommended. Use a grounded, non-sparking ventilation systems, approved explosion-proof equipment intrinsically safe electrical systems. Avoid any dust build-up by frequent cleaning and suitable construction of the storage areas. Storage facility should be made of fire resistant materials. Keep storage areas, separate from work areas.Store away from sources of heat or ignition.
