Clear, colorless liquid. Warning! Flammable liquid and vapor. Potential health effects (acute and chronic): Symptoms of exposure: Effects of eye exposure: Causes eye irritation. May result in corneal injury. May cause painful sensitization to light. Contact produces irritation, tearing, and burning pain. Effects of skin contact: May be absorbed through the skin in harmful amounts. Prolonged and/or repeated contact may cause irritation and/or dermatitis. Effects of ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure. Effects of inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation. Irritation may lead to chemical pneumonitis and pulmonary edema. Exposure produces central nervous system depression. May produce numbness in the extremities. May cause liver abnormalities. May cause visual abnormalities. Target Organs: Central nervous system, liver, eyes, skin, mucous = membranes. Routes of entry: Inhalation, ingestion or eye or skin contact.
Emergency and first aid procedures:
Get medical assistance for all cases of over-exposure.
Skin:
Get medical aid. Immediately flush skin thoroughly with water
for at least 15 minutes. Remove contaminated clothing and shoes.
Wash clothing before reuse.
Eyes:
Get medical aid immediately. Immediately flush thoroughly with
water for at least 15 minutes, occasionally lifting the upper and
lower eyelids. Do not allow victim to rub or keep eyes closed.
Inhalation:
Get medical aid immediately. Remove to fresh air immediately.
Artificial respiration if breathing has stopped. If breathing
is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation.
If breathing has ceased, apply artificial respiration using oxygen
and a suitable mechanical device such as a bag and a mask.
Ingestion:
Do NOT induce vomiting. If conscious and alert, give 2-4 cupfuls of
milk or water. Never give anything by mouth to an unconscious person.
Get medical aid immediately.
Notes to Physician:
Treat symptomatically and supportively.
Flash Point....................64°F Fire Extinguishing Media: For small fires use dry chemical, CO2, or "alcohol" foam, water spray to cool fire-exposed containers and disperse vapor; water on fire itself may be ineffective. For large fires, use water spray, fog or alcohol-resistant foam. Do NOT use straight streams of water. Cool containers with flooding quantities of water until well after fire is out. Firefighting Procedure: Wear self-contained breathing apparatus in pressure-demand full protective gear. Fire and explosion hazards: Dangerous fire and explosion hazard. Vapor can travel distance to ignition source and flash back. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Can release vapors that form explosive mixtures at temperatures above the flashpoint. Hot organic chemical vapors or mists are susceptible to sudden spontaneous combustion when mixed with air. Ignition may occur at temperatures below published autoignition or ignition temperatures. Ignition temperatures decrease with increasing vapor volume and vapor/air contact time and are influenced by pressure changes. Ignition may occur at typical elevated temperature process conditions, especially in process operating under vacuum if subjected to sudden ingress of air, or outside process equipment operating under elevated pressure if sudden escape of vapors or mists to the atmosphere occurs.
Spill Response: Evacuate the area of all unnecessary personnel. Wear suitable protective equipment listed under exposure/personal Protection, including self contained breathing apparatus. Eliminate any ignition sources until the area is determined to be free from explosion or fire hazards. Contain the release and eliminate its source, if this can be done without risk. Absorb spill with an absorbent, non-combustible material such as earth, sand or vermiculite. Scoop up with non-sparking tool and containerize for proper disposal. Comply with federal, state, and local regulations on reporting release. Refer to regulatory information for reportable quantity and other regulatory data. Disposal considerations: EPA (Environmental Protection Agency) waste numbers: CAS# 78-93-3 - waste number U159 (Ignitable waste, Toxic waste CAS# 108-10-1 - waste number U161 (Ignitable waste)
Handling: Use only in a well-ventilated area. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin and clothing. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof = equipment. Avoid contact with heat, sparks and flame. Empty containers may contain residue - do not pressurize, or expose empty containers to heat, sparks or open flames. Do not take internally. Eye wash and safety equipment should be readily available. Storage: Keep away from sources of ignition. Store in a flammables area. Store in cool, dry well ventilated area.
An eyewash facility and a safety shower should be available. Use adequate
general or local exhaust ventilation to keep airborne concentrations below
the permissible exposure limits.
