(1) Each TA will perform all of the experiments before the laboratory begins. He/she must have know how to operate all equipment and perform all computer tasks required of the students.
(2) TA's must review the UMBC Laboratory Safety Guide and the ACS publication "Safety in Academic Chemistry Laboratories" before the semester begins. He/she must be familiar with all emergency procedures relevant to the Advanced Laboratory course.
In-lab responsibilities of the TA:
(1) Prior to the laboratory period, the TA(s) are responsible for obtaining all expendible items from the undergraduate stockroom needed for the experiment (dry ice or LN2, distilled water, solvents, soap, paper towels, etc.).
(2) The TA(s) will make sure that each student is wearing protective eyewear at all times while they are in the laboratory. If a student is found not wearing protective eyewear, they will be immediately asked to leave the lab. Repetitive occurrences will jeopardize the student's grade and/or permission to be in the course.
(3) The TA(s) will check each students pre-laboratory assignment in their notebook and initial prior to the student beginning the experiment. The TA will assign a grade of 0 - 10 based on the quality of the completed assignment. If the assignment is deemed to be unsatisfactory for the student to carry out the experiment, he/she will be asked to leave by the TA and will not be allowed to begin the experiment until the pre-lab is corrected.
(4) The TA(s) will ensure that the work area and balance area are cleaned by the students prior to departing for the day. The assigned TA is responsible for making sure that all glassware and reagents used for the day are washed and put away (or placed to dry) by the students. If this does not happen, the TA(s) is responsible for clean up at the end of the laboratory period.
