Steps When Entering the Lab
If you are the first person entering lab, spray down the door handles and the light switch with Lysol.
Use hand sanitizer upon entry into the lab. Do this every time you enter the lab.
Spray down your workspace with Lysol before starting to work.
General Precautions and Steps
Work that can be done at home, should be done at home, in order to minimize the number of people in lab space.
Use Google Hangouts and Zoom for all meetings with other lab members.
Maintain 6 feet social distancing at all times while at the lab and while on University of Kentucky property.
Based on a recent study, over 13 feet (4 meters) social distancing should be maintained:

Wear a mask when entering and leaving the lab.
You are required to wear a mask when entering the building.
Therefore, you must have a mask with you when coming to lab.
Wearing an N95 and above mask is preferred, but this may not be possible due to limited supplies.
Wear a mask in lab, if others are present.
This is now required.
Wash hands or use hand sanitizer frequently after touching surfaces or being in rooms with others.
The virus can be active for 9 hours on human skin:

Spread out across the lab as much as possible to maximize separation.
Walk around in unoccupied paths as much as possible.
Wipe down any package that is received using dilute bleach solution.
Let Prof. Moseley know if any cleaning supplies run out or are running low.
Steps When Eating and Drinking
Wipe down the kitchen counter-top surface with dilute bleach solution or spray with Lysol.
Wash any dish and utensil before use for at least 20 seconds.
Wash any dish and utensil after use for at least 20 seconds.
Steps When Using the Restrooms
Wash hands with soap and water for at least 20 seconds after using the bathroom facilities.
Steps When Leaving the Lab
Last person leaving should spray down the door handles and light switches with Lysol when leaving.
Face Masks
Face Mask Recycling
Testing of SARS-CoV-2 virus on porous surfaces like cardboard indicate that the virus loses infectiousness in about a day.
Therefore, face masks should be recyclable without direct resterilization by cycling through a few masks, one per day.
Exposure to sunlight for at least one hour is a good additional measure to take, followed by storage in a brown paper bag.
The brown paper bag is preferred over a plastic ziploc bag, since the paper bag allows the mask to dry.
Of course, use of a direct resterilization procedure like exposure to concentrated UV-C radiation would be better.
However, do NOT stay in a room with concentrated UV-C radiation and never directly look at the radiation source.
Face Mask Decontamination Methods

Making a Homemade Face Mask
Here is a recent published article on the use of two different fabrics to make the most effective homemade masks out of common fabrics:

Making Dilute Bleach Solution
Use 4 teaspoons per quart of water.
Bleach is photoreactive, so the solution should be stored in an opaque container.
