First Aid Measures

Ingestion

Do not induce emesis. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.

Inhalation

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.

Skin

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.

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

Irritation of the lungs and bronchial tree may be seen.

Skin

Irritation or possibly burns of the skin may be seen after direct exposure to the liquid.

Eyes

See Skin.

Ingestion

Mild to moderate oral and esophageal irritation may occur.

Hazards

Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back.

Dizziness and loss of consciousness may occur after exposure to high airborne concentrations. No data were available to assess the teratogenic potential of this agent. <br>No data were available to assess the potential effects of exposure to this agent during pregnancy or lactation.

Fire Fighting Measures

Flash Point

12.2 (closed cup)

Fire Fighting

Use water spray, alcohol foam, dry chemical or carbon dioxide. Water may be ineffective.

Fire Potential

Dangerous, when exposed to heat or flame. Flammable

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.

Incompatibilities

Can react vigorously with oxidizing materials. Hydrolyzes with water to isopropyl alcohol and formic acid which is toxic.

Stability

No data.

Combustion Products

Fire may produce irritating, corrosive and/or toxic gases.
