| CAS REGISTRY NUMBER: |
75-15-0 |
| NAME ASSESSMENT CODE: |
CBB |
| MATERIAL NAME: |
CARBON DISULFIDE; Carbon bisulfide |
| MOLECULAR FORMULA: |
CS2 |
| DESCRIPTION: |
Watery liquid; Colorless to
yellow; Rotten egg to sweet odor; Sinks in water.;
Flammable, irritating vapor is produced. |
| ACTIONS IN CASE OF
EMERGENCY: |
|
Avoid contact with liquid and vapor. Keep people away. Wear goggles,
self-contained breathing apparatus and rubber overclothing (including
gloves). Shut off ignition sources and call fire department. Stop
discharge if possible. Stay upwind and use water spray to "knock
down" vapor. Isolate and remove discharged material. Notify local
health and pollution control agencies.
FIRE
FLAMMABLE.
Flashback along vapor trail may occur. Vapor may explode if ignited
in an enclosed area. Wear goggles, self-contained breathing apparatus,
and rubber overclothing (including gloves). Extinguish with dry
chemical or carbon dioxide. Water and foam may be ineffective on fire.
Cool exposed containers with water.
EXPOSURE
CALL FOR MEDICAL AID.
VAPOR
Irritating to eyes, nose and throat. If inhaled, will cause nausea,
vomiting, difficult breathing, or loss of consciousness. Move to
fresh air. If breathing has stopped, give artificial respiration. If
breathing is difficult, give oxygen.
LIQUID
Will burn skin and eyes. Harmful if swallowed. Remove contaminated
clothing and shoes. Flush affected areas with plenty of water. IF IN
EYES, hold eyelids open and flush with plenty of water. IF SWALLOWED
and victim is CONSCIOUS, have victim drink water or milk and have
victim induce vomiting. IF SWALLOWED and victim is UNCONSCIOUS OR
HAVING CONVULSIONS, do nothing except keep victim warm.
WATER POLLUTION
HARMFUL TO AQUATIC LIFE IN VERY LOW CONCENTRATIONS.
May be dangerous if it enters water intakes. Notify local health and
wildlife officials. Notify operators of nearby water intakes.

| RESPONSE TO DISCHARGE: |
Issue warning-high flammability; Restrict
access; Evacuate area |
| LABEL CATEGORY: |
Flammable liquid |
| LABEL CLASS: |

| IMO/UN DESIGNATION: |
3.1/1131 |
| DOT ID NO.: |

| EXPOSURE INFORMATION: |
|
Personal Protective
Equipment (SAF) : Only self-contained breathing mask
with full face, approved by the
United States Bureau of Mines, is
recommended. If the vapor
concentration exceeds 2% by volume or
is unknown, supplied-air respiratory
equipment of appropriate design with
full face masks should be used by all
persons entering contaminated area.
Masks should be used only for
emergency situations and should be
located accordingly. Almost any type
of industrial clothing is
satisfactory. Splashes of small
quantity are not harmful to fabrics,
and evaporation from clothing is
quite rapid. Clothing should, however,
be removed and the skin washed with
water. Goggles should be used when
there is any danger of CS2 splashes
or spray.
Threshold Limit Value (TLV) : 10 (ppm)
Short Term Inhalation Limit (SIL): 200 (ppm for 10 minutes);100 (ppm for
30 minutes and 50 ppm for 60 minutes.)
Toxicity By Ingestion (DHI) : Grade 2; rat LD50 = 0.1 - 0.99 g/kg
Late Toxicity (LTX) : Non-specific liver cell damage in
rats; higher incidence of upper
respiratory disease in humans.
Vapor Irritant
Characteristics (VIC) : Vapors cause moderate irritation such
that personnel will find high
concentrations unpleasant. The effect
is temporary.
Liquid or Solid Irritant
Characteristics (LSI) : Causes smarting of the skin and first
-degree burns on short exposure and
may cause secondary burns on long
exposure.
Odor Threshold (ODT) : 0.21 (ppm)
IDLH Value (IDL) : 500 (ppm)
|
| SYMPTOMS FOLLOWING
EXPOSURE: |
|
ACUTE EXPOSURE: mild to moderate irritation of skin, eyes, and
mucous membranes from liquid or concentrated vapors; headache,
garlicky breath, nausea, vomiting, diarrhea (even after vapor
exposures), and occasionally abdominal pain; weak pulse,
palpitations; fatigue, weakness in the legs, unsteady gait, vertigo;
mania, hallucinations of sight, hearing, taste, and smell in acute,
massive vapor exposures; central nervous depression with respiratory
paralysis; death may occur during coma or after a convulsion.
|
| TREATMENT FOR EXPOSURE: |
|
INHALATION: remove victim promptly from contaminated area.
Administer oxygen and artificial respiration if needed.
SKIN CONTACT: wash affected areas with copious quantities of water.
INGESTION: induce vomiting and follow with gastric lavage and saline
cathartics.

| FIRE/INFLAMMATION DATA: |
|
Flash Point (FLP) : -22 (deg.F C.C.)
Flammable Limits in Air (FLA) : 1.3 to 50 (%)
Fire Extinguishing Agents (EXT) : Dry chemical, carbon dioxide
Fire Extinguishing Agents
NOT to be Used (NFE) : Water and foam may be ineffective on
fire.
Special Hazards of
Combustion (TCP) : Toxic gases are generated; wear self
-contained breathing apparatus.
Ignition Temperature (IGT) : 212 (deg.F)
Electrical Hazard (EHZ) : Contact of the liquid or vapor with
the surface of a lighted electric
light bulb could result in ignition.
