First Aid Measures

Ingestion
Seek medical assistance.
Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

Handling and Storage

Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation
Inhalation of vapors may produce respiratory irritation. Aspiration pneumonitis, pneumatocele or pulmonary edema has developed after ingestion, iv injection, or the use of turpentine as a vaginal douche.
Skin
May cause irritation or burns.
Eyes
See Skin.
Ingestion
Inhalation of vapors may produce respiratory irritation. Aspiration pneumonitis, pneumatocele or pulmonary edema has developed after ingestion, IV injection, or the use of turpentine as a vaginal douche.
Hazards
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
UN (DOT)
3295

Exposure Controls/Personal Protection

Personal Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Exposure Effects
Headache and dizziness may occur with vapor exposure. Seizures may develop after large ingestions. CNS depression including coma may occur following turpentine ingestion. The use of turpentine and water as a vaginal douche has resulted in abortion.

Fire Fighting Measures

Flash Point
35
Autoignition
255
Fire Fighting
Use of water spray when fighting fire may be inefficient. Small Fires: Dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam. Use water spray or fog; do not use straight streams.
Upper exp. limit
6.7
Lower exp. limit
.8
Fire Potential
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.

Accidental Release Measures

Small spills/leaks
Make no contact with the spilled material. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.

Stability and Reactivity

Stability
No data.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
