First Aid Measures

Ingestion

Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.

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

Most cases of aluminum related dermal reactions are due to chronic exposure.

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

Pulmonary fibrosis, asthma, copd, chronic interstitial pneumonia, sarcoid-like lung granulomatosis, dyspnea, cough and pneumothorax may occur after chronic inhalation.

Skin

Dermatitis, irritation, delayed hypersensitivity, telangiectases and granulomas may occur from dermal contact with aluminum.

Ingestion

Chronic aluminum hydroxide use may cause constipation.

Exposure Controls/Personal Protection

Personal Protection

Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.

Respirators

Use NIOSH/MSHA approved respirator appropriate for exposure of concern.

Exposure Effects

Encephalopathy has been reported in patients with renal failure. This may range from mild personality changes and speech disorders to severe obtundation, seizures, coma and death. Fatal encephalopathy with status epilepticus has occurred after the use of aluminum-containing bone cement in vestibular neurectomies. Aluminum has also been linked to the histopathology of alzheimer disease. Occupational exposure to aluminum has been associated with cognitive deficits. Aluminum in drinking water has been linked to central nervous system birth defects. Some aluminum compounds have proven teratogenic in laboratory animals; however, overall, aluminum is not considered teratogenic.

Poison Class

Fire Fighting Measures

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. Use agent most appropriate to extinguish fire.

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.

Incompatibilities

Strong oxidizing agents.
