^{We typically close once a semester for 3–5 days to perform a thorough cleaning. We reduce our hours on holidays, during the Pentecost break, and during the summer break. Training operations are also limited during the Christmas break; the facility is usually completely closed for about eight days over Christmas and New Year’s. In addition, there may be occasional restrictions of 2–3 hours, usually on 2–3 days per semester, due to classes.}
