In response to Miyoki-kun's report, Furuta-san, Iwata-kun, and I checked around the IO rack, above which the ceiling might contain water. Although we are not sure if there is possibility that water could drop from the ceiling, we protected the instruments around the rack with a cover sheet of the rack and an umbrella. I fastened one corner of the cover sheet to the leg of the ladder, which happened to be there. In retrospect, I think that it was not a good solution, because somebody might use the ladder. I asked Kokeyama-san to change it tomorrow.
Attached are some photos after the quick and dirty protection.
[Michimira, Kokeyama]
we untied the velcro tape (magic-tape) of the plastic cover from the radder and tied to a power reel just next to the rack.
In addition, some more safety remedies were applied:
- We unwrapped the power reels not to make the heat. Three reels; one next to ioo rack, one next to imc rack and one close to the big desk close to PR2 chamber were done.
- A pair of 24V DC power supply used for ioo rack did not have a cable between the two (to connect the - of one with + of the other to make the common ground). We also fixed it.
- SR560 used as an additional IMC control servo was put on a drainboard.
