General Description
A colorless gas with a sweet odor. Shipped as a liquefied gas under own vapor pressure. Contact with the liquid may cause frostbite. Easily ignited. Vapors are heavier than air. Leaks may either be liquid or vapor. May asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat containers may rupture violently and rocket.

The information in CAMEO Chemicals comes from a variety of
data sources.
Reactivity Alerts
- Highly Flammable
- Polymerizable
- Peroxidizable Compound
Air & Water Reactions
Highly flammable. Reacts slowly with water to form acetaldehyde, reaction is not hazardous unless water is hot or acids are present. Form dangerous peroxides when exposed to air.
Fire Hazard
Behavior in Fire: Containers may explode. Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. (USCG, 1999)
Health Hazard
Inhalation causes intoxication, blurring of vision, headache, dizziness, excitation, loss of consciousness. Liquid or concentrated vapor irritates eyes and causes frostbite of skin. Aspiration of the liquid will cause chemical pneumonitis. (USCG, 1999)
Reactivity Profile
VINYL METHYL ETHER reacts vigorously with oxidizing materials. Explosive in the form of vapor when exposed to heat, flame or strong oxidizing agents. Reacts, possibly explosively with halogens (bromine, chlorine) or hydrogen halides (hydrogen bromide, hydrogen chloride) [Baker, 1980, p. 487]. On contact with dilute acids or even mildly acidic solids (calcium chloride, ceramics) undergoes rapid, exothermic homopolymerization, which cannot be prevented by antioxidants. Must be stored in the presence of base [MVE Brochure, Billingham, ICI, 1962].
Belongs to the Following Reactive Group(s)

The
Response Recommendation fields
include isolation and evacuation distances, as well as recommendations for
firefighting, non-fire response, protective clothing, and first aid. The
information in CAMEO Chemicals comes from a variety of
data sources.
Isolation and Evacuation
Excerpt from ERG Guide 116 
[Gases - Flammable (Unstable); polymerization hazard]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 100 meters (330 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 800 meters (1/2 mile).
FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 1600 meters (1 mile) in all directions; also, consider initial evacuation for 1600 meters (1 mile) in all directions. (ERG, 2024)

Firefighting
Excerpt from ERG Guide 116 [Gases - Flammable (Unstable); polymerization hazard]:
DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED.
SMALL FIRE: Dry chemical or CO2.
LARGE FIRE: Water spray or fog. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2024)

Non-Fire Response
Excerpt from ERG Guide 116 [Gases - Flammable (Unstable); polymerization hazard]:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Stop leak if you can do it without risk. Do not touch or walk through spilled material. Do not direct water at spill or source of leak. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. If possible, turn leaking containers so that gas escapes rather than liquid. Prevent entry into waterways, sewers, basements or confined areas. Isolate area until gas has dispersed. (ERG, 2024)

The information in CAMEO Chemicals comes from a variety of
data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
