Safety and Disposal: Safety goggles should be worn at all times in the lab. Be cautious of acidic and basic solutions since they can cause skin burns and eye damage. Liquids and solids are to be disposed of in properly labeled waste containers per MSDS guidelines. It is recommended that the lab be done a small scale to minimize solvent and chemical exposure. If hexanes and iodine are used, it is advisable for the teacher to leave these compounds in the hood for student use and to use and exercise appropriate safety precautions.
