Description:

I have a sample of uranium dioxide powder dispersed in ethanol, housed in the tumbler mill vessel. I want to evaporate the ethanol in the fume hood.

Note: Please ensure the formulation is clear, and the steps are presented in a sequential manner.

$------------------$

Ethanol Evaporation Process:

$-$ Verify that the fume hood is functioning properly.

$-$ Place a steel tray in the work area to contain and facilitate the cleanup of any spills.

$-$ Position the tumbler mill vessel in the steel tray and cautiously open the lid to avoid ethanol spills.

$-$ Avoid any ignition sources near the tumbler mill vessel.

$-$ Keep the tumbler mill vessel open throughout the evaporation process, which extends for $48$ hours.

$-$ Conduct periodic checks during work hours and record them in a separate log$.$

$-$ Restrict access to the fume hood and use signs to alert other laboratory users that the equipment is in use with uranium materials.

$-$ The final check should occur at the end of the work shift, and an early morning check before the arrival of other laboratory users.

$-$ Upon completion of the evaporation process, tightly seal the vessel to ensure it is airtight. Utilize insulating tape to secure the lid onto the body. Use a locking clip to fasten the lid to the body.

$-$ Place the sealed container in a double Ziploc bag and return it to the glovebox following Lab$-$SOW$-003$ rules.

$-$ Empty and weigh the powder inside the glovebox to determine the amount of loss, then update the inventory records accordingly.
