Post these signs on the equipment in your lab! It will be easier for everyone to understand which equipment can be turned off after every use (green), only at the end of the day (yellow), or whether it should not be turned off at all (red).

You can print these signs on a sheet of 10 shipping labels (2" x 4" label size). Otherwise contact the Office of Energy & Sustainability for a copy.
