**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Extremely flammable. May form explosive peroxides. Harmful by
inhalation.Possible risk of irreversible effects.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Prolonged or repeated skin contact may cause
severe exacerbation. A single prolonged skin exposure is not likely
to result in the material being absorbed in harmful amounts.
Ingestion:
Harmful if swallowed. Possible aspiration hazard.
Inhalation:
May cause liver and kidney damage. Causes irritation of the mucous
membrane and upper respiratory tract. Vinylidene chloride is highly
volatile. Its odor is not adequate as a warning characteristic.
Overexposure produces central nervous system depression.
Chronic:
May cause liver and kidney damage. Chronic exposure may cause lung
damage. Laboratory experiments have resulted in mutagenic effects.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
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.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Antidote:
None reported.
**** 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.
During a fire, irritating and highly toxic gases may be generated by
thermal decomposition or combustion. Use water spray to keep
fire-exposed containers cool. Fire or excessive heat may result in
violent rupture of the container due to bulk polymerization.
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. Fight fire from protected location or maximum
possible distance.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
**** 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. 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. Use a spark-proof tool. Provide ventilation.
Place under an inert atmosphere. A vapor suppressing foam may be used
to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Remove contaminated clothing and wash before reuse. Ground and bond
containers when transferring material. Avoid contact with eyes,
skin, and clothing. Empty containers retain product residue, (liquid
and/or vapor), and can be dangerous. Keep container tightly closed.
Handle under an inert atmosphere. Store protected from air. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames. Use only with adequate
ventilation. Keep away from heat, sparks and flame. Avoid breathing
vapor or mist. Destroy contaminated leather clothing. Pure vapor
will be uninhibited and may polymerize in vents or other confined
spaces. Materials of construction recommended for vinylidene chloride
monomer include steel, stainless steel, and baked phenolic-lined
steel. Recommended gasketing materials include Teflon and Viton
fluoroelastomers.
Storage:
Keep away from sources of ignition. Do not store in direct sunlight.
Store in a tightly closed container. Purge container with nitrogen
before resealing. Keep dry. Store in a cool, dry, well-ventilated
area away from incompatible substances. Refrigerator/flammables. Do
not expose to air. Do not store in aluminum containers. Long-term
storage is not recommended. Do not store in copper or copper alloy
storage vessels.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Use explosion-proof ventilation equipment.
Facilities storing or utilizing this material should be equipped with
an eyewash facility and a safety shower.

The adverse effects of VDC exposure are related to its metabolites.
Because of the reduced amounts of the epoxide, acyl chloride, and
halogenated aldehyde formed in humans compared to that in rodents,
humans exposed to similar VDC concentrations are considered to be at
substantially lower risk for adverse health effects than rodents.
