Training Purposes Only JEM SAIBO MAINT JMU (Ver. 1.0) 5 Saibo Rack Maintenance Overview Equipments found in Saibo Rack Maintenance Operations  CB Shield - Prevent Electro Magnetic Interference while UV Lamps are ON. (- Block JEM Cabin lights to make fluorescence observation efficiently.)  CB Relief Valve - Release air in CB Air-tight Chambers if JEM cabin should depressurize.  BZK Wipe - Benzalkonium chloride antiseptic towelettes are alcohol-free wet wipes used for general antiseptic cleansing.  Meas Exp Unit B (CBEF Canister) - Canister is a container of samples and equipments.

Crew entrapmentAir-tight Chamber When CB is in ‘Stowed Configuration’ fill gaps between the OC and Outer Chassis with Gap Protectors to prevent crew entrapment. Crew Exposure to Broken Glass Operation Chamber Verify no broken glass in Operation Chamber before opening OC front panel. OC Lamp, UV Lamps Do not touch OC Lamp or UV Lamps with bare hand. Oil from hands may cause breakage. Time Critical OperationN/A Dos and Don’tsAir-tight Chamber Pull out/stow Air-tight Chamber slowly at about 10 cm per minute to avoid damage to bellows. OC CameraRaise OC Camera (Lens and Flexible Arm) above the inner plate before stowing the Operation Chamber. Difficulty in OpsN/A Possible Mis-OpsN/A NOTE: Underlined key points have been covered by CB Advanced Training.

CategoryEquipmentKey Points Crew Safety Electrical ShockSample Tray, Centrifuge Before attaching/detaching the Canisters to/from the Sample Tray/ Centrifuge, turn power to Canister off by switches on the Sample Tray/Centrifuge. Entanglement with rotating device Incubator Unit 1G Verify visually through the Observation Window that the Centrifuge is not rotating before opening the door of the Incubator Unit 1G. CentrifugeWhen attaching/detaching the Canisters to/from the 1G Centrifuge, lock turntable of the Centrifuge. Time Critical OperationN/A Dos and Don’tsIncubator UnitDo NOT touch inside Incubator Unit with bare hand to keep it clean. Sample Tray, Centrifuge Be careful not to pinch fingers when releasing drawer locks of slide rails on Sample Tray/Centrifuge.
