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.

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.

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.
