Safety

Before working in any GE Healthcare MR suite or performing any GE Healthcare service procedure, you must:

Have read and understood all hazard conditions and safety requirements in the latest revision of the GE Healthcare MR Service Safety Manual (5452735).
Have successfully completed all relevant GE Healthcare Environmental Health and Safety (EHS) courses (or for non-GE employees, equivalent workplace training courses).
Comply with all site-specific training and workplace safety requirements.

If you have any safety concerns at any time, do not begin work or immediately stop work and move to a safe location. Immediately contact your supervisor or site safety officer for instructions on how to proceed.

DANGER

Electrocution hazard

Hazardous voltage is present when the cabinet is energized.

Before beginning any work, perform LOTO. See the MR Service Safety Manual (5452735).

Warning

Potential retinal burn

Invisible laser radiation may be emitted from disconnected fibers or connectors causing a retinal burn.

Avoid staring into beams or viewing directly with any optical instruments.

Reminders:

Always turn off laser sources before you inspect fiber connections.
Always keep a protective cap on unplugged fiber ferrules.

Notice

Potential component damage

Electrostatic discharge (ESD) can cause permanent damage to electronic components.

Observe the following ESD precautions:

Work on a static-free mat.
Wear a static strap to ensure that any accumulated electrostatic charge is discharged from your body to the ground.
Create a common ground for the equipment being worked on by connecting the static-free mat, static strap, and peripheral units to that piece of equipment.

Notice

Potential component damage

The SFP optical transceiver is very sensitive to electrostatic discharge (ESD), dust, and body oil. When working with the SFP optical transceiver:

Always use ESD protection when handling the SFP optical transceiver to prevent early failure.
Never touch the SFP optical transceiver without being properly grounded.
Never touch the end face of the optical connectors.
Never re-use lens tissue or cleaning swabs.
Always keep a protective cap on unplugged fiber connections.
Always inspect the connection before cleaning.
The SFP must be shipped in antistatic packaging. Discard any SFP shipped or stored without proper ESD protection.
Some SFPs are shipped in insulated envelopes which can produce excessive contaminates. Do not open these containers in the area where you will be working with the SFP. Remove the antistatic bag containing the SFP and move to a clean area to work.
