First Aid Measures

Ingestion
Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
Inhalation
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
Skin
Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse.
Eyes
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.

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
Death normally occurs from sudden cardiorespiratory arrest. Pulmonary edema may develop. Tachypnea may occur secondary to acidosis.
Skin
Redness.
Eyes
Redness.
Ingestion
Common initial symptoms are heartburn, followed by nausea and abdominal cramps, vomiting and occasionally diarrhea. Later symptoms include back pain and severe abdominal pain.

Exposure Controls/Personal Protection

Personal Protection
Protective gloves. Safety goggles.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Exposure Effects
Central nervous system depressant effects, including drowsiness, headache, progressive obtundation and coma have preceded death. Drowsiness is usually delayed approximately 24 hours after ingestion. Meningismus, cerebral edema and hemorrhage, and neuropathies have been reported.
Poison Class
4

Fire Fighting Measures

Flash Point
232
Fire Fighting
Alcohol foam. Water or foam may cause frothing.

Accidental Release Measures

Small spills/leaks
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.

Stability and Reactivity

Stability
No data.
Decomposition
On combustion, forms irritating fumes.
