Key Points for Rad Silk Operations
NOTE: Underlined key points have been covered by CBEF Advanced Training.
Category Key Points
Crew Safety Electrical Shock Before attaching/detaching the Canisters to/from the Sample Tray/ Centrifuge, turn off power to Canister by switches on the Sample Tray/Centrifuge.
Entanglement with rotating device
Verify visually through the Observation Window that the Centrifuge is not rotating before
opening the door of the Incubator Unit 1G.
When attaching/detaching the Canisters to/from the 1G Centrifuge, lock turntable of the
Centrifuge.
Time Critical Operation N/A
Dos and Don’ts Do NOT touch inside Incubator Unit with bare hand to keep it clean.
Be careful not to pinch fingers when releasing drawer locks of slide rails on Sample Tray/Centrifuge.
