First Aid Measures

Ingestion
Do NOT induce vomiting, get medical attention.
Inhalation
Remove victim to fresh air; if breathing is difficult, administer oxygen; call physician.
Skin
Wash with copious quantities of water; treat frostbite by use of warm water or blankets.
Eyes
Wash with copious quantities of water; consult an eye specialist.

Handling and Storage

Storage
Grounding and bonding required. Store in a well-ventilated area. Avoid contact with light. Store in a tightly closed container. Keep separated from incompatible substances.
Handling
Handle in accordance with all current regulations and standards. Subject to storage regulations: U.S. OSHA 29 CFR 1910.101. Grounding and bonding required.

Hazards Identification

Inhalation
Respiratory tract irritation has not been reported, but may be predicted from other irritant properties.
Skin
Skin irritation may be noted.
Eyes
Eye, nose, and throat irritation may be seen.
Ingestion
Seek medical attention.
Hazards
Containers may explode. Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back.
UN (DOT)
1087

Exposure Controls/Personal Protection

Personal Protection
Organic-vapor mask; plastic or rubber gloves; safety glasses.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Exposure Effects
Central nervous system depression could occur from anesthetic effects.
Poison Class
4

Fire Fighting Measures

Flash Point
-56
Autoignition
287
Fire Fighting
Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

39
Lower exp. limit
2.6
Fire Potential
Very dangerous; can react vigorously with oxidizing materials. Extremely flammable.

Accidental Release Measures

Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.

Stability and Reactivity

Stability
Polymerizes easily.
Incompatibilities
React vigorously with oxidizing materials.
Decomposition
When heated to decomposition it emits acrid smoke and irritating fumes.
Combustion Products
Fire may produce irritating and/or toxic gases.
