There is a pin hole water leak coming from the DIW supply pipe going into the ISAC B1 hot lab - rm 06. It appears to be on the solder / joint. The leak is very small at this point. Mostly just a drip.

 Monday, January 13, 2020, 10:30: Leak noted in HC area by Chad to ISAC Ops.

Monday, January 13, 2020, 13:32: The water leak was found to be coming from the sinks in the ISAC B1 Cold Lab. Target cleaning was occurring at the time as well. Soap / detergent smell was noted in the water that had dripped down to the area in front of the South Hot Cell in ISAC B2.

Rob Shanks entered a fault report. 

Running the main cold lab tap or the fume hood tap did not yield a leak, however, dumping a large quantity of water into the 2 main sinks in the ISAC B1 cold lab causes the leak to become apparent. It's likely the large volume of water causes a brief back flow in the pipe in ISAC B2 which then leaks until the flow recovers.

The pipe joint with the leak has been circled in the attached photo. 

Anders & I both witnessed the leak to confirm the source. 

 Temp was noted to be high @ 50 deg C.

Adjusted the regulators to 35 deg C. Ran both the eye-wash station & shower. Waited 20 minutes. Ran them again and tuned.

It was noticed on Wednesday that the glove box was not regulating pressure properly & the H2O sensor was reading (Very unstable) anywhere from 30 ppm to 0.25%. The box was isolated & checked for leaks. Unable to vent properly except manually.

One of the solenoid valves for venting the glove box fails to open. Will need replacement. The filter also appears to be saturated. Regeneration is required once the solenoid valve is replaced. Prior to replacing the valves, the LaC must be safely removed. This process is being initiated. (John W. & Darwin O.)

Thursday, April 07, 2022, 12:00: While preparing to remove LaC, the roughing pump (1) stopped operating. It didn't appear to seize, just no longer powered up. Multiple outlets attempted. Vacuum group contacted & they brought us a replacement.

Thursday, April 07, 2022, 12:21: Pump was replaced. (Pump 2).

Friday, April 22, 2022, 11:30: The roughing pump failed (Pump 2) & shut-off. Appears to have seized. Oil?

Was replaced by Vacuum Group in the afternoon with 3rd pump.

Monday, April 25, 2022, 09:13: Roughing pump failed & shut-off. (Pump 3). The oil was completely drawn out of it & into the ventilation line (To EF14).

Fault: 14843

Friday, June 01, 2022, 12:00: RP changed with a new IDP15 roughing pump. Fixed.

 On November 10th / 11th a site wide power outage occured. Once power was restored, the Ar glove box had intermittent issues with the solenoids & blower. The blower did not start & the solenoids often got stuck or ceased operating. 

Yesterday Randy B inspected the connections to see if they were receiving enough power. It was good from the main plug-in, through to the PLC, however was dead at fuse positions 3 & 4 on the rear panel. Both fuses were changed, but that did not help. We did some fidgeting in the back & the solenoid function returned. It was left overnight.

Thursday, November 30, 2023, 08:30: <- Approx. Initial check: Dropped a crumpled Kimwipe inside the glove box to check for air flow / blower function. It did not move. Blower was not functioning, but the solenoids did. De-energized the glove box completely. 

Removed the old corroded fuse holders, added a pair of modified new ones. Cleaned a couple of corroded critical connections. Installed the new fuses, re-plugged it back in. Function returned to normal. The Kimwipe was also moving, verifying the blower is again operational.
