Laboratory Safety Guidelines Quiz

Access to the laboratory is not limited.

Off-hour work does not require pre-approval by the Department Manager/Director.

Open infectious materials procedures are conducted outside of the BSC.

It is safe to place potentially infectious items in desk areas.

Personnel with fresh lacerations or skin lesions should notify their manager before working in the lab.

Aerosols can be generated during pipette mixing of culture dilutions.

Aerosol formation can be reduced by keeping the pipette tip above the surface of the fluid.

Rapid aspiration of fluid into the pipette can help generate aerosols within pipettes.

Pipette contamination is a common cause of false-negative results.

Aerosol-resistant tips for pipettes have a hydrophilic microporous filter bonded onto the walls of the pipette tip.

Specimen containers should only be opened in a Biosafety Cabinet (BSC) to prevent contamination.

Breaking a thin film in the neck of culture tubes with a pipet tip can help prevent aerosol formation.
