Changes

On Friday June 6, I took down a poster from the door to lab 402 and began to remove tape and adhesive residue from the doors. I continued this task on Monday June 9. I started with a rag wet with ethanol, but there were still some Scotch tape and thicker layers of masking tape on the door. I had hoped I could scrape off the tape with cardboard, but the cardboard was much too thick. I also tried my fingernails, but they were not well suited to the task either. I had considered a razor but was afraid it would damage the finish of the door. However, as I continued to use the rag with ethanol, Jim appeared with a razor blade and began scraping away the tape. After seeing him use the razor without harming the door, I took it and used it to remove the tape. I still had to use ethanol to wipe away the traces of adhesive afterwards. When I was done, I put the rags, now spotted with adhesive, on the shelf above the other used rags in lab 405.

June 12: I vacuumed the conference room and the mat outside it.

June 12: I vacuumed the conference room and the mat at the door. The yellow vacuum in 403 was the best machine to use, but it was not very good. To achieve the best suction I had to use it without any attachments. After using it, I had to shake the tube and a good length of the hose over a trash can to make sure the trash would not fall out later on the floor.

June 13-20: I found some MSDS sheets that we did not have. I printed ones that are clearly important on June 20. I detailed my findings in a spreadsheet. I did not find some of the items on the chemical inventory. I don't know whether to remove them or not.
