Feb 10, 2022 Fluorescent tubes were replaced in fume hood #2.
Oct 29, 2021 The HF fume hood (fume hood #3) drain was flushed for an hour and then opened up at the locations indicated by the red arrows. Seven plastic items, HF strips and a screw were removed from the drain. The drain is currently clear, and as it now has a cover, hopefully no further items will fall in.
Oct 15, 2021 The HF fume hood faucet was found broken off and lying on the counter in the beginning of the expedition. The fitting was cleaned out, and an attempt was made to attach the faucet with PVC cement. Unfortunately, the cement had turned into gel and did not work very well. The faucet is fine and works well, but there is a very small leak from the top of the fitting. This should not be an issue, as this faucet is very rarely used. If used, care should be taken to place a drip catcher underneath the base of the faucet.
Oct 10, 2021 A 4-inch crack was discovered toward the FWD PORT corner of the HF fume hood countertop. It was repaired with two applications of gel coat (each batch consisting of approximately a tea spoon of ISO NPG Poolcoat and four drops of MEKP hardener). Two large washers were placed under the fume hood counter corner to prevent flexing and re-cracking.
Jul 18, 2021 When the fume hood drains were inspected, plastic items were discovered in the HF hood (fume hood #3) drain. Upon removal of the upper items, some of lower ones (a small Nalgene bottle etc) fell down into the drain. To prevent this from happening in the future, a cover was designed and 3D printed for the drain.
The drain will be opened up during the next tie-up, and an attempt will be made to clear the potential obstructions from the pipe.
Oct 12, 2020 Replaced the fluorescent tubes in the chem lab HF hood (fume hood #3). Normally you would slide up the top front panel to gain access to the light fixture, but we have ducting running right above the panel, which makes sliding it up impossible. To be able to remove the front panel, you have to take off the first row of ceiling tiles and remove the ceiling supports. Once you have access to the light, it is only necessary to remove the cover plate on the STBD end of the light. This allows you to slide the light cover out and off. The fluorescent tubes are standard ones that you can get from the ship's electrician.
