Laboratory Safety

Question 2 • FL-2000315-Biology 1 CR

Which action is an aseptic technique that would reduce the chance of bacteria on a lab table contaminating a lab notebook?

Answer
c
covering the surface of the lab table with paper towels
w
wiping off the surface of the lab table with a disinfectant
t
tying back long, loose hair before writing in the lab notebook
w
wearing protective gloves when touching the lab table

Explanation

Disinfectant kills or reduces bacteria on the lab table, so wiping the surface directly lowers the chance that bacteria will transfer to the notebook. Covering the table with paper towels does not necessarily remove or kill the bacteria, and tying back hair or wearing gloves does not clean the table surface. The correct choice is wiping the lab table with a disinfectant.
