When cataloged materials are exchanged the catalog record for holdings is modified accordingly. A small amount of waste that is classified as hazardous is generated from the collections and molecular laboratory. The collections and laboratories have approval through the UA Office of Environmental Health and Safety to use these compounds. All hazardous wastes are bottled in the laboratory, labeled, and turned over to the appropriate UA offices for safe disposal. For emergencies, the collections and laboratories have fire extinguishers, first aid kits, shut offs for gas, water, and electricity, and emergency showers in case of dangerous chemical contact.
Fume hoods are available when working with hazardous materials.
Many of these laboratories are also equipped with showers, eye wash basins, sprinkler systems, fire extinguishers, and radioactive areas.
