Take out the trash to the trash room when the container gets full. You can usually find large empty trash bags lying around left behind by cleaning people. Check to see if any necessary or useful equipment is missing, or would be useful if bought. Make up a budget to pay for any such equipment, and all the chemicals which need to be purchased, and submit it. The back room shelf is used, among others, for paper storage.
Some people use it for their personal paper storage.
Make sure that all the Ash down paper is labeled so that it does not get mixed up. While at work, keep the ventilation in the back room running to prevent build up of harmful fumes. I actually leave it running at all times, just because the motor is flaky and sometimes will not re-start. Keep the white HEPA air filter running at all times to keep the dust out of the air. The carbon filter element needs to be replaced when the indicator light goes on and stays on - every year or so.
