Question

a vertical laminar flow hood should be cleaned: select one: a. starting on the right, wiping side to side and working back away from the user. b. starting on the left, wiping side to side and working back away from the user. c. starting in the front, wiping side to side and working back away from the user. d. starting in the back, wiping side to side and working forward toward the user.

Answer 1

c. Starting in the front, wiping side to side and working back away from the user.

When cleaning a vertical laminar flow hood, it is important to start in the front and work your way back to avoid contaminating the already cleaned areas. Wiping side to side helps to remove any particles or dust that may have accumulated on the surface of the hood. It is recommended to use a clean, lint-free cloth and a solution of 70% alcohol or a disinfectant approved for use in a cleanroom environment.
