Hazards and Protection.
Keep tightly closed in a cool dry location. Store only with compatible chemicals.
Avoid contace with skin, eyes and clothing. Laboratory use only. Use in a chemical hood with proper 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.
Full protective clothing and NIOSH approved SCBA with full facepiece operated in the pressure demant/positive pressure mode.
Evacuate and ventilate area. Wear appropriate protective equipment. Sweep up and place in appropriate container and hold for disposal. Was contaminated surfaces.
Strong oxidizing agents.
Oxides of nitrogen, sulfur dioxide, ammonia and sulfur trioxide.
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.
OSHA: PEL (8 h TWA): 15 mg/m3.
Aluminum accumulates in brain tissue and is a neurotoxic agent. Ataxia and seizures have been reported following ingestions and in patients with compromised renal function receiving bladder irrigations. Mental status changes, including obtundation, lethargy and confusion, may occur.
Ingestions of small amounts of alum may cause dryness and a puckering sensation of mucous membranes in the mouth and throat. Rectal enemas containing 1% ammonium alum caused mild cramping and nausea in the majority of patients.
Inhalation is irritating and may cause airway congestion. Symptoms are usually transient. Respiratory depression has been reported in patients with severe aluminum encephalopathy.
Concentrated solutions may irritate abraded skin.
Dilution: immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 4 ounces/120 ml in a child). Do not induce vomiting.
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.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
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.
