Safety

This section will be divided into two sub-sections: loading operations and shifting operations. For more detailed information about the laboratory hardware, please see the Hardware Operations section.

Loading Operations

During loading periods, the D-Eggs will be transported both into and out of the freezer. This involves entering the freezer and moving heavy objects. Please wear close-toed shoes (no sandals) which have sufficient stability to work on uneven surfaces. Following freezer cycles, the floor of the freezer may be wet.

Always work with at-least 2 people during this time - the D-Eggs and wooden ramp are both heavy!

Shifting Operations

After the D-Eggs are safely located inside the freezer, shifting operations begin. Main concerns include the use of high voltage and the ultra-violet laser. In the event that the optics inside the box must be adjusted, pleaes turn off the laser. If the laser must remain on during this time, use eye protection located next to the laser box before opening. Before turning the laser on, inspect the box to ensure it is correctly sealed.

High voltage is supplied via the mini-fieldhubs. Do not adjust cables connected to D-Eggs, the tabletop mainboard, the jumperboxes or mini-fieldhubs if power is enabled. You can confirm if power is enabled by inspecting the LEDs visible on the mini-fieldhub front panel. If you are uncertain, confirmed by inspecting the power switches located on the back of the mini-fieldhubs. When in doubt, contact an expert.

Before enabling power, it is also important to confirm that the copper grounding wires connecting the mini-fieldhubs to the freezer are secured. If not, disable power on the mini-fieldhubs and re-attach the wires.

Additional devices include the function generator which drives the laser and the GPS system (module + antenna). These are also electronic devices - ensure they are powered on safely.
