From weaver.646 at osu.edu Wed Apr 2 09:25:01 2025 From: weaver.646 at osu.edu (Weaver, Tyler) Date: Wed, 2 Apr 2025 13:25:01 +0000 Subject: [Prep Lab Students] Weather Message-ID: Hi Everyone, There is a potential for severe weather tonight and into tomorrow morning. While this is likely to occur outside of working hours, I want to remind everyone what to do in the event of a severe weather emergency while on campus. Remember, a tornado watch means that conditions are favorable for tornadoes to develop, but one has not been confirmed. A tornado warning means a tornado has been spotted or detected by radar, and immediate action should be taken to seek shelter. Every building on campus has a Building Emergency Action Plan, BEAP. You have completed an online training about these at some point this academic year. Consider reviewing section 6.13 ?Severe Weather Emergencies? of the BEAP for any buildings you may be visiting soon. If a tornado warning is issued, and you are in Celeste: Do not wait for instructions. Equipment in use should be turned off. Labs should evacuated & locked. Everyone should proceed to the basement and wait in the hallways. If the weather service allows the tornado warning to expire, this will serve as your all-clear. As a reminder, we will plan to have lab as long as the University stays open. This means that everyone scheduled to be present will be expected to report to their assigned shifts. Please let me know if you have any questions.

You are accountable for the entirety of all messages sent to you by the Prep Lab Staff. Emails sent to preplabstudents at lists.osu.edu are archived for your convenience at https://lists.osu.edu/pipermail/preplabstudents/ Howdy! Week 14 is our last full week of lab! [cid:image003.png at 01DBA714.1ACA6D60] Experiment Notes-Refer to the window notes and gather sheets for additional details. Please see the Week 13 email for notes on AAP and BLP. NAP This is a new one that Sarah has been working on. Students will be working in pairs. Equipment needed will be on the bench beside hood A. We?ll be using vortex mixers, which are new to gen chem. To activate the mixer, students just need to press their centrifuge tube down into the top cone. It will turn off when pressure is released. Waste is as expected, liquids and chemical solids go in the white can, rinsed plastic tubes in the blue bucket. SCM This one only uses distilled water, and it can be taken directly from the taps in the labs. Be prepared to direct students to the window cart for replacement burets, pipets, beakers, and pipet pumps. Restock the cart as needed. BLP Students that missed BLP earlier in the semester will be completing BLP. All other 1220/1620/1920H make-ups will be PKA. TAs should tell you how many people are doing a make-up so that you can provide them with the correct number of unknowns- they won?t need a whole box. There are three unknowns per TA: one green liquid in falcon tubes, packaged solids in a black bag, and packaged solids in a clear colorless bag. You?ll also be passing out printed copies of the BLP lab manual pages. PKA This is essentially WST with different steps and reagent labels. This experiment is done individually. pH meters and probes will be on the bench closest to Hood A.The probes with the black cables will need to be attached to the top of the meters whereas the new probes will need to be attached to the probe and meter via the supplied white cables. Connections are made on the top of the meter by pushing and turning. Both pH probe types will have either a black o-ring or blue rubber piece at the top of the probe shaft to cushion it from the glass storage tube and help seal in the storage solution. These should stay at the top of the probes while the students are taking readings. If a student claims their pH meter is ?broken?, they should have their TA try to calibrate it before bringing it to the window for an exchange. Emma has prepared a guide on how to handle pH meter issues. It will be available in the window for reference. VOL This one has A LOT of equipment and solutions. Students will be using the multimeter kits which are on the bench beside Hood A. If they report that one is not working properly, please just swap the whole kit for one of the replacements in the window. Emma has made a guide on what to do with these. Please read it. The provided electrode kit is to be used for both Parts A and B. One magnetic stir bar is provided in the kit to help distinguish between iron and zinc electrodes. The students will be sanding the oxidation layer off the electrodes with emery paper/cloth. This should be done on the provided cover stock; the cover stock should be placed on the provided black plastic tray. The whole sanding procedure should be done under a snorkel. Each room has been provided with 7 trays since they only have 7 snorkels. Students should not be sanding directly on the lab bench. Doing this makes me sad :( There?s a ton of waste for this experiment. Liquids should be discarded in the chemical waste beakers (white can). Contaminated paper, including spent emery paper, should go in the blue bucket. Spent electrodes should be collected in the canister in the window. Spent porous cups and Pasteur pipets should be discarded in the orange bucket. Other Important Information End of Term Termination (it?s not as scary as it sounds) Anyone not planning to return to the prep lab after spring semester will be terminated on the day of spring commencement. Those of you that are not planning to work over the summer, but will return for fall, will be terminated at the end of the semester. Anyone that is working over the summer will be terminated at the end of the summer semester. This will be done so that we can put everyone into new positions that have a differential pay scale based on your start date. Starting pay will be $13/hr. After one calendar year students will be paid $13.50. Students top out after two calendar years, or a promotion to a lead student assistant, with a pay rate of $14.00/hr. Spring 2025 Schedule We will continue to follow our normal spring schedule until reading day. We will not have anyone scheduled to work on reading day, but anyone wanting hours is welcome to drop in. Our end of semester party will be on reading day, April 22nd, from 4-6pm. Everyone will be required to work a minimum of 4 hours during finals week. Details on sign-ups will come later. Fall 2025 As mentioned in a previous message, the fall 2025 schedule is now open on Teams for everyone returning in the fall. The application for fall 2025 is also now open for anyone interested in joining our team: go.osu.edu/au25preplabapp Please let us know if you have any questions!

Additionally, watching shows or movies and playing video games during work hours is not allowed. Also, ensure that you are wearing lab-appropriate attire or have a plan to change before entering the lab. The lab attire section from the prep lab guidebook is pasted below for your convenience. Clothing worn in the lab should provide skin protection from chemical spills and splashes. Appropriate clothing includes long pants or skirts that go to the ankle. Ankles should not be exposed. If a vessel containing chemicals falls to the floor, it is vital to make sure no exposure to the lower leg/ ankle occurs. At a minimum, all the red areas shown in the figure to the right should be completely covered before entering the lab. Pants made of spandex, or other thin and/or skin-tight materials, and clothing with holes are not acceptable, even if your lab coat covers the holes. Shoes should cover the entire foot (closed-toe and closed-back). Ankles should be completely covered. Extremely loose or bulky clothing is also not appropriate for the lab. Baggy sleeves are a fire hazard or may knock over lab supplies. The best materials to wear in the lab are natural fibers, such as cotton. It is acceptable to wear scrub pants or sweatpants over leggings or shorts. Chem stores, room 180 Celeste, typically has scrub tops and pants available for purchase. Proper PPE only needs to be worn when in lab spaces, it is not required in the prep lab office. Long hair must be tied back, as it can catch fire if it gets too close to an open flame or get pulled into a rotating object. Please reach out with any questions.

If someone is making you feel uncomfortable in our workspaces, causing you to avoid going into certain areas, etc. please do not hesitate to speak with any of the Prep Lab Staff about it. The sooner we know of the issue, the sooner we can begin work to resolve it. 1. In light of the tragic recent events at Florida State University, I want to remind you all of the resources available for situations like this: The Department of public safety has several resources on their site: https://dps.osu.edu/active-aggressor Specifically, in Celeste, all doors are lockable. * On the first floor, the door by the ice machine can be locked with the Allen key hanging next to it. The door between the office and lab has a thumb knob. The door from the office into the hallway has a switch under the latch. * On the second and third floors, all doors have a thumb knob. Most, soon to be all, lab rooms have black vinyl shades that can be pulled down to cover the windows by the doors. Please let us know if you have any questions.

But I didn?t want to miss the chance to share a few thoughts as we wrap up the semester. We?ve been through a lot together this semester, and I?m incredibly proud of what we?ve accomplished as a team. Thank you for everything you?ve done over the past few months. From running the first spring VOL since before COVID, to packing 70,000 tubes for SAL (!), to keeping our lab running day after day?none of it would have been possible without your effort, flexibility, and teamwork. To those of you graduating: congratulations! We?ve truly enjoyed having you with us, and you?ll be sincerely missed. I have no doubt you?ll go on to do great things?whether in labs, classrooms, hospitals, or wherever your path leads. Please keep in touch?we?d love to hear what you?re up to! And for those returning next semester: we?re looking forward to all of our future adventures together.
