Section 3 - Hazards Identification

Appearance: clear, colorless to pale yellow liquid. Flash Point: -30 deg C.
Danger! Extremely flammable liquid and vapor. Vapor may cause flash fire. Harmful if swallowed, inhaled, or absorbed through the skin. Causes eye, skin, and respiratory tract irritation. Stench. Aspiration hazard if swallowed. Can enter lungs and cause damage. May cause nervous system effects. May increase risk of cardiovascular disease. This substance has caused adverse reproductive and fetal effects in animals.
Target Organs: Cardiovascular system, nervous system, reproductive system.


Potential Health Effects
Eye: May cause severe eye irritation.
Skin: Causes skin irritation. May be absorbed through the skin in harmful amounts. Prolonged and/or repeated contact may cause defatting of the skin and dermatitis. Dermatitis and vesiculation may result from skin contact with the vapor or liquid. Dermal contact with concentrated solutions may cause burning pain, erythema, exfoliation. (Merck Index)
Ingestion: May cause digestive tract disturbances. May cause effects similar to those for inhalation exposure. Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal. Can cause nervous system damage. Ingestion may cause convulsions, seizures and possible coma.
Inhalation: Intoxication can involve all parts of the central and peripheral nervous systems including damage to the nerves with paresthesias, muscle weakness, unsteady gait, and tremors. Exposure may accelerate the development or worsen, coronary heart disease.
Chronic: Prolonged or repeated exposure can cause psychic abnormalities such as anxiety, depression and excitability. May cause reproductive and fetal effects. Chronic exposure may cause visual disturbances. Repeated exposure may cause central and peripheral nervous system damage and digestive tract disturbances. Chronic exposure may cause coronary heart disease. Chronic toxicity of carbon disulfide includes marked psychic disturbances ranging from extreme irritability to mania with hallucinations, tremors, auditory and visual disturbances, weight loss, blood dyscrasias. (Merck Index)

Section 4 - First Aid Measures

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid imme diately. Do NOT allow victim to rub eyes or keep eyes closed.
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion: Potential for aspiration if swallowed. Get medical aid immediately. Do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If vomiting occurs naturally, have victim lean forward.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician: Effects may be delayed. Observe patient.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. Combustion generates toxic fumes. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. May be ignited by friction, heat, sparks, or flame. Extremely flammable liquid and vapor. Vapor may cause flash fire. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. May accumulate static electricity. Because of the very low autoignition temperature, ignition is easily accomplished by contact with hot surfaces such as light bulbs, steam pipes, or engine exhaust pipes.
Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or appropriate foam.
Flash Point: -30 deg C ( -22.00 deg F)
Autoignition Temperature: 90 deg C ( 194.00 deg F)
Explosion Limits, Lower:1.3%
Upper: 50.0%
NFPA Rating: (estimated) Health: 3; Flammability: 4; Instability: 0

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Provide ventilation. Evacuate unnecessary personnel. Approach spill from upwind. Use only non-sparking tools and equipment. Control runoff and isolate discharged material for proper disposal. Use water spray to cool and disperse vapors and protect personnel.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Do not breathe vapor. Use only with adequate ventilation. Keep away from heat, sparks and flame.
Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Keep under a nitrogen blanket. Flammables-area. Store protected from heat and direct sunlight.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Use explosion-proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.

Carcinogenicity:
CAS# 75-15-0: Not listed by ACGIH, IARC, NTP, or CA Prop 65.

Epidemiology: Based on the results of studies of workers exposed to carbon disulfide & supporting data from animal studies, the nervous system appears to be the critical target for carbon disulfide-induced toxicity, manifested most often as reduced conduction velocityin the peripheral nerves & impaired performance in psychomotor testing. Other effects for which there is considerable weight of evidence in humans exposed to CS2 include alterations in serum lipids & blood pressure that are associated with increased riskof cardiovascular disease, systemic ophthalmological effects, including those on color vision and damage to the blood vessels of the retina, and (with higher exposures) increased mortality from heart disease.
Teratogenicity: Animal studies have indicated behavioral effects and reduced weight gain by rat inhalation. Premature fetal death and stunted fetus' were shown by rat inhalation and the oral route. Specific developmental abnormalities included craniofacial abnormalities including the nose and tongue by rat inhalation, effects on the eyes, ears and homeostasis by rat inhalation, and other unspecified abnormalities by the oral route in rabbits.
Reproductive Effects: Hypospermia, abnormal sperm morphology, menstrual cycle irregularities and pain have been reported in humans. Effects on fertility and paternal effects have been reported in animal studies by the oral and inhalation routes of entry. These included effects on the prostate, seminal vesicle, Cowpers gland, urethra and spermatogenesis. Other studies have not found adverse effects. Conflicting studies regarding the ability of carbon
