Section 3: Hazard Identification

Emergency overview: Prolonged exposure may cause allergic skin reaction,
kidney damage, or liver damage. Prolonged exposure may also cause headaches, nausea,
drowsiness, or unconsciousness.

Appearance: Clear liquid.

Flash Point: 10.0° C / 50.0° F (TCC)

Potential Health Effects

Eye: May cause irritation of the eyes.

Skin: This product is moderately irritating to skin. May cause skin sensitization.

Ingestion: This product is potentially harmful if swallowed.

Inhalation: May be irritating to nose, throat, or respiratory tract.

Chronic: May cause headache, nausea, drowsiness, or unconsciousness.

Section 4: First Aid Measures

Eyes: Flush eyes with copious amounts of water for at least 15 minutes, while
holding eyes open. If irritation develops or persists, seek medical attention.  

Skin: Immediately wash affected areas with soap and water. Seek medical attention.
Contaminated clothing should be removed and discarded to avoid further exposure.

Ingestion: Never give anything by mouth to an unconscious person. If product
is swallowed, immediately provide 2 glasses of water. Seek immediate medical attention.

Inhalation: Remove victim to fresh air and seek immediate medical attention.
If victim is not breathing, provide artificial respiration.

Notes to Physician: Treat supportively and symptomatically.

Section 5: Fire Fighting Measures

General Information: Wear full protective clothing with a self-contained
breathing apparatus set to positive pressure in fire conditions.

Auto Ignition Temperature: 815.0° F / 435.0° C.

Flash Point: 50.0° F / 10.0° C (TCC).

Flammability: Flammable.

Hazardous Combustion Products: Flammable vapors.

Unusual Fire/Explosion Hazards: Heat may cause polymerization. Containers
may explode if heated. Vapors can travel to sources of ignition and flashback

Extinguishing Media: Use water spray, foam, dry powder, or carbon dioxide.

Protective Measures: NIOSH/MSHA approved self contained breathing apparatus
when fighting fires, along with full protective clothing.

Section 6: Accidental Release Measures

Spills/Leaks: Absorb any spill with an inert material. Transfer liquids
and solid material to separate containers that are approved for recovery or
disposal. Any contaminated monomer may be unstable. Add inhibitor to prevent
polymerization. Spills on porous surfaces may contaminate groundwater.

Section 7: Handling and Storage

Handling: Always wear appropriate safety equipment while handling this product,
including chemical splash goggles and an air purifying respirator (MSHA/OSHA approved)
equipped with organic vapor cartridges and dust/mist filters when airborne 
concentrations are up to ten times the TWA/TLV.

Storage: Do NOT store under oxygen-free environment. Leave air space over
liquid surface in all containers and introduce air periodically if product is stored
more than six months. Monomer shelf life is one year. Containers are hazardous when

Section 8: Exposure Controls and Personal Protection

Engineering Controls: Local exhaust is required when working with this
product. Safety showers and eye wash stations should be readily available in work
