First-aid measures

Inhalation: Remove victim from area of exposure to fresh air or remove source of contamination. If symptoms of carbon disulfide exposure develop: headache, dizziness or excitement, before attempting rescue wear appropriate protective equipment . Apply artificial respiration if breathing stopped. Avoid mouth-to-mouth contact by using mouth guards or shields. Give oxygen if breathing is difficult. Keep warm and at rest until fully recovered. Seek immediate medical advice.Skin contact: Remove contaminated clothing and shoes without delay. Immediately flush area with lukewarm water for at least 20 minutes, or until the chemical is removed. If swelling, redness, blistering or irritation occurs seek medical assistance immediately. Clothing have to be decontaminated before re-using, contaminated shoes or leather shall not be re-use.Eye contact: SOLUTIONS: Immediately flush eyes with plenty of lukewarm water gently flowing for at least 15 minutes, or until the chemical is removed, while holding the eyelid open.DUST: Do not allow victim to rub eye. Let the eye water naturally for few minutes. Have victim look left and right, and then up and down. If dust does not dislodge, flush gently with lukewarm water for 5 minutes, while holding the eyelid open. Immediately obtain medical assistance.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. In case of breathing has stopped, trained person should begin artificial respiration. Seek immediate medical assistance.

Fire-fighting measures

Flammability : Solid xanthates are reactive flammable materials. Contact with small amounts of water or water vapor 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. Solid xanthates are reactive flammable materials. Xanthate dusts are combustible dusts. Fire and explosion: The dry powder of xanthates can form an explosive dust-air mixture, which can be ignited by a spark or flame. 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. On solid xanthates use carbon dioxide, dry chemicals or appropriate foam.Do not use water or water based extinguishers on solid xanthates since extremely flammable and very toxic carbon disulfide will be released.If possible, isolate materials not yet involve in the fire or use water flooding 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.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 Extinguishing media: On solid xanthates use 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. Restrict access to area until completion of clean-up. 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 walking on them.Notify government occupational and environmental authority. 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. Spills of solution, soak up with absorbent material that does not react with spilled substance. In case of solid xanthates do not get water on spilled solid material. Vacuum spills of solids instead of sweeping.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.
