First Aid Measures

Ingestion

Significant systemic toxicity is not expected after acute ingestion; gastrointestinal decontamination is generally not warranted.

Inhalation

Remove from exposure to fresh air immediately.

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

Store in a cool, dry place. Keep container closed when not in use.

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

Respiratory depression, pulmonary edema, emphysema, and atelectasis have occurred in animals following large doses.

Skin

Allergic contact dermatitis has been reported. Eczematous reactions of onychial and paronychial tissues have been reported in patients using acrylic plastic nails. Dystrophic nail changes may persist for months. Irreversible loss of the fingernails has occurred.

Paresthesia have been reported. Headache, irritability, drowsiness and dizziness may occur.

Fire Fighting Measures

Flash Point

101

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.

Accidental Release Measures

Small spills/leaks

Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. While using the appropriate protective equipment, clean up spills immediately.

Stability and Reactivity

Incompatibilities

Oxidizing agents, reducing agents.

Stability

table under normal temperatures and pressures.

Decomposition

Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
