This is optional but recommended. The best is a lab coat because it protects you and your good clothing. At the very least avoid wearing clothing which you value, because some chemicals will stain, weaken fibers or eat holes in clothing. Since eyes are especially vulnerable and hard to replace, you must purchase and use a pair of safety glasses if you do not wear glasses ordinarily. Contact lenses are generally worse than no eye protection at all and should not be used in lab.
Inexpensive glasses are available in the Bookstore.
If you occasionally forget to bring your safety glasses, we have a limited supply of loaners in the department, but we do not guarantee their availability or quality.
