| First Aid Measures | Back to Contents | 【Ingestion】
Activated charcoal may cause vomiting and aspiration. It should be reserved for patients with large ingestions or significant coingestants. Protect patients airway with a cuffed endotracheal tube. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Seizures: administer a benzodiazepine iv; diazepam (adult: 5 to 10 mg, repeat every 10 to 15 min as needed. Child: 0.2 To 0.5 Mg/kg, repeat every 5 min as needed) or lorazepam (adult: 4 to 8 mg; child: 0.05 To 0.1 Mg/kg). Consider phenobarbital if seizures recur after diazepam 30 mg (adults) or 10 mg (children > 5 years). Monitor for hypotension, dysrhythmias, respiratory depression, and need for endotracheal intubation. Evaluate for hypoglycemia, electrolyte disturbances, hypoxia. | 【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 | Back to Contents | 【Storage】
Store in a cool, dry, well ventilated place away from all sources of ignition. | 【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 | Back to Contents | 【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. | 【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. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substance may be transported hot. | 【UN (DOT)】

| Exposure Controls/Personal Protection | Back to Contents | 【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. | 【Poison Class】

| Fire Fighting Measures | Back to Contents | 【Flash Point】
38 | 【Fire Fighting】
Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources. | 【Upper exp. limit】
6.8 | 【Lower exp. limit】
.8 | 【Fire Potential】
HIGHLY FLAMMABLE. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. |
| Stability and Reactivity | Back to Contents | 【Incompatibilities】
May react vigorously with strong oxidizing agents May react exothermically with reducing agents to release hydrogen gas. | 【Stability】
No data. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
