Guidelines for care & Use of Dry Solvent Stills [Example]

16. Undergraduate Lab Rooms # 7, 101, 102, 103, 104, 105, 106, 111
Specific Decontamination Procedures for Equipment and Bench top Surfaces which have come into
contact with Highly Toxic Waste
Include here methods of cleaning up work surfaces in hoods or bench tops so as to render traces of
toxic chemicals benign.
Teaching lab bench tops and hoods in rooms 101 through 111 are primarily the responsibility of
housekeeping and stockroom personnel. Teaching Assistants are responsible for pointing out cleaning
needs and occasionally assisting in such cleanup, themselves. The laboratory managers and teaching
instructors will notify the above mentioned personnel for any special cleaning requirements. The students
will also be responsible for cleaning their particular work area, especially at the end of each semester. It
may be necessary occasionally to clean up organic stains with acetone or ethanol. Mineral acids should
be diluted with water and neutralized with baking soda stored in the back of each lab before cleanup.
Soap is also located on the back window benches of each lab. Specific stockroom and housekeeping
assignments are listed under the Housekeeping section of this manual.
Stains on the newly renovated Organic Lab benchtops (rooms 102 and 106) can be cleaned with
scrubbing pads soaked with water and baking soda.
If highly toxic waste is generated in any undergraduate lab, specific decontamination procedure
literature references will be included along with actual experimental procedures by the lab instructor.
