 HAZARD ALERT: Strong oxidizer; may explode if heated under confinement; may explode at temperatures greater than 210 °C; explodes more readily if contaminated with combustible material; slightly toxic by ingestion; body tissue irritant. LD50 2217 mg/kg. Storage: Inorganic #8 away from all combustibles. We recommend that this dangerous substance be kept in a Flinn Saf-Stor TM Can. Disposal: #26b
Shelf Life: Poor; hygroscopic; store in a Flinn Chem-Saf TM bag. Soluble: Water, alcohol and alkalis.
Color and Odor: White, odorless solid.
CAS No. 6484-52-2
Safety Purchase Suggestion: Do not store large quantities. Technical Note: The granular lab grade material is easier to work with than the crystalline reagent, which tends to clump together. The lab grade material gives excellent results in quantitative ther- mochemistry experiments.
Incompatibility: Acids, chlorates, combustible materials, flammable liquids, nitrites, sulfur, carbon, organic compounds and metals (especially finely divided metals).
Storage: Inorganic #2
Disposal: #26a
Shelf Life: Indefinite
Soluble: Slightly in water.
Color and Odor: White, odorless solid. CAS No. 7722-76-1

A Strong Base and the Human Eye
A strong base like ammonium hydroxide is capable of very, very rapid and extensive eye damage. In fact, tissue damage to the human eye may occur in just the first 30 seconds of exposure. The use of chemical splash goggles and prompt access to a func- tional eyewash are essential when ammonium hydroxide and other strong bases are used. If chemicals are to be used, chemical splash goggles must be worn!
