Disposal and Cleanup:  Dispose of any excess fluids down the drain with the water running. Allow the faucet to run for about 30 seconds to dilute the fluids. Place the specimen in its storage bag and seal tightly. If you are finished working with your specimen, put the bag into an opaque trash bag for disposal in the household garbage. Rinse and carefully air dry the dissection tools, and return the materials to your equipment kit. Sanitize the workspace with isopropyl alcohol (or other non-bleach disinfectant) and paper towels. If this is insufficient for removing grease during cleanup, use soap and water, followed by more alcohol/disinfectant. Which of the following are true? 

Storage of Specimens If it is necessary to store the specimen between work periods, you may choose to place it in the plastic storage bag with as much of the original solution as possible. Establishing an airtight seal is the best way to retain specimen integrity and prevent drying out of the specimen. First, squeeze as much air out of the specimen bag as possible before securing the opening with a rubber band, tape, or a binder clip. After closing the bag, the specimen can be stored in a larger, airtight box or bag at room temperature.
