**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Very toxic by inhalation. Toxic in contact with skin and
if swallowed.Stench.Highly toxic.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause dermatitis.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause liver damage. May be harmful if swallowed.
Inhalation:
May be fatal if inhaled. Vapors may cause dizziness or suffocation.
Causes upper respiratory tract irritation. Exposure may cause blood
abnormalities. Causes irritation of the mucous membrane.
Chronic:
Effects may be delayed. Exposure to high concentrations may cause
tearing, cyanosis (bluish discoloration of skin due to deficient
oxygenation of the blood), central nervous system depression or
hemorrhage in the lung. Prolonged or repeated exposure may cause
hemolytic anemia which can lead to renal failure.
**** 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.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. 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:
Treat symptomatically and supportively.
**** 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. Water runoff can cause environmental damage. Dike
and collect water used to fight fire. Vapors may form an explosive
mixture with air. Vapors can travel to a source of ignition and
flash back. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Will burn if
involved in a fire. Use water spray to keep fire-exposed containers
cool. Water may be ineffective. Material is lighter than water and a
fire may be spread by the use of water. Containers may explode in
the heat of a fire. Flammable liquid and vapor. Vapors may be
heavier than air. They can spread along the ground and collect in
low or confined areas. May be ignited by heat, sparks, and flame.
Containers may explode when heated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Water may be
ineffective. Do NOT use straight streams of water. For large fires,
use water spray, fog or regular foam. For small fires, use dry
chemical, carbon dioxide, water spray or regular foam. Cool
containers with flooding quantities of water until well after fire is
out.
**** 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. Use water spray to dilute spill to
a non-flammable mixture. Avoid runoff into storm sewers and ditches
which lead to waterways. Clean up spills immediately, observing
precautions in the Protective Equipment section. Remove all sources
of ignition. Absorb spill using an absorbent, non-combustible
material such as earth, sand, or vermiculite. Do not use combustible
materials such as sawdust. Use a spark-proof tool. Provide
ventilation. A vapor suppressing foam may be used to reduce vapors.
Water spray may reduce vapor but may not prevent ignition in closed
spaces.
**** SECTION 7 - HANDLING and STORAGE ****
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. Keep away from heat, sparks and flame. Avoid ingestion and
inhalation. Do not ingest or inhale. Use only in a chemical fume
hood. Wash clothing before reuse. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Flammables-area.
**** 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 only under a chemical fume hood.
Exposure Limits
CAS# 2179-60-4:
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.

**** SECTION 11 - TOXICOLOGICAL INFORMATION ****
RTECS#:
CAS# 2179-60-4 unlisted.
LD50/LC50:
Not available.
CAS# 624-92-0: Inhalation, rat; LC50 = 15,850 ug/m3/2Hr.; Oral, rat:
LD50 = 535 mg/kg. The toxicological properties of this product are
partially based upon the hazards associated with Methyl disulfide
(CAS# 624-92-0). Carcinogenicity:
Methyl propyl disulfide -
Not listed by ACGIH, IARC, or NTP.
**** SECTION 12 - ECOLOGICAL INFORMATION ****
Ecotoxicity:
Estimated Koc values of 36-218 suggest moderate to high soil mobility
of solution-phase methyl disulfide. Volatilization and
photodegradation are expected to be major fate processes for methyl
disulfide in water. Aquatic hydrolysis, bioconcentration and
adsorption to sediment are not expected to be important fate
processes because of the lack of hydroyzable group and high water
solubility. Based upon a vapor pressure of 28.7 mm Hg at 25 deg C
methyl disulfide is expected to exist primary in the vapor phase in
the ambient atmosphere.
