以下為「Biosafety and Basic Laboratory Facilities」e等公務園+測驗解答,共 30 題,供公務人員學習參考。

Which description is correct?

  • There are 4 risk groups of microorganisms
  • There are 4 biosafety levels of laboratories
  • Risk group levels do not have to always correspond to biosafety levels
  • All of the above are correct

Special practices for a BSL-2 laboratory include limited assess and posting biohazard signs

There are 4 risk groups (RGs) of microorganisms and RGs are designated from 1 (the lowest risk) to 4 (the highest risk)

If you plan to work with potentially infectious biological materials, you do not need to consider

  • Regulations and guidelines
  • Risk group (RG) microorganisms
  • Working time
  • The laboratory location/workspace

To which risk group of microorganisms does SARS coronavirus (SARS-CoV) belong?

  • RG-1
  • RG-2
  • RG-3
  • RG-4 microrganisms

Effective treatment and preventive measures are not usually available for

  • RG-1
  • RG-2
  • RG-3
  • RG-4 microrganisms

No safety equipment is reqired in BSL-1 laboratories

A BSL-2 plus lab can be used to handle which biological materials?

  • Drug-resistant RG-2 bacteria
  • Second generation lentiviral vectors
  • High concentrations (>106 PFU/mL) of RG-2 viruses
  • All of the above are correct

Which inforamtion must be included in a biohazard sign?

  • Biosafety level
  • Name of the lab director
  • Mobile phone number
  • All of the above are correct

Risk group levels must always correspond to biosafety levels.

RG1 microorgamisms pose no individual and community risks

Good microbiological laboratory practices are required only in BSL-1 laboratories

Which is not the minimum requirement for an ABSL-1 lab?

  • Standard animal care and management practices
  • Autoclave
  • sink
  • PPE

Regardless of experimental procedures, RG4 pathogens can not be handled in which biosafety level?

  • BSL-1
  • BSL-2
  • BSL-3
  • BSL-4

Biosafety laboratories handling infectious biological materials are classified into four biosafety levels, BSL-1, BSL-2, BSL-3, and BSL-4

Laboratory exposures of RG2 pathogens may cause serious infection, but effective treatment and preventive measures are available and the risk of spread of infection is limited

Autoclave is absoultly required as a secondary barrier for BSL-2 laborarories

In order to protect the lab researcher and staff from laboratory-acquired infections, it is only required to employ facilities suitable for the risk level of the biological materials

Laboratory practices and biosafety equipment of an ABSL-2 laboratory include

  • Hazard warning signs
  • Class I or II BSCs for activities that produce aerosols
  • Decontamination of waste and cages before washing
  • All of the above are correcct

Which of the following descriptions of a typical BSL-2 laboratory is incorrect?

  • Personnel wear Lab coats and gloves
  • Autoclave is required as a secondary barrier
  • limited access
  • Biohazard sign is required

BSL-2 plus laboratory is a BSL-2 laboratory with positive pressure airflow, and adopting BSL-3 biosafety practices and procedures

Biosafety can

  • Reduce risk to human/animal health and safety
  • Protect the environment
  • Protect the biological materials
  • All of the above are correct

Animal Biosafety Levels, ABSL-1 through 4, provide for practices, equipment, and facilities that are comparable to the laboratory biosafety levels

Key aspects of good biological laboratory practices at least include

  • Aseptic techniques
  • Disinfection and sterilization
  • Proper sample and waste handling
  • All of the above are correct

Which description of ABSL laboratories is incorrect?

  • Personnel must have specific training
  • Personnel can work alone without be supervised by an authorized individual
  • Laboratory should be separated from the general traffic patterns of the building
  • All of the above are correcct

If the laboratory space is limited, an autoclave nearby the laboratory is acceptable, but for safety, a transportation route to autoclave should be planned

Organisms that present certain biocontainment and/or biosecurity concerns (e.g., low pathogenic avian Influenza) can be handled in which biosafety level?

  • BSL-1
  • BSL-2
  • BSL-2 plus
  • BSL-3

Which of the following descriptions of a typical BSL-1 laboratory is incorrect?

  • Personnel wear Lab coats and gloves
  • Having benches and sink
  • Limited access
  • No biohazard sign is required
