Questions Fully Solved.
Ebola virus is an example of a pathogen associated with which Risk Group? - Answer Risk group 4
Ebola virus is a Risk Group 4 pathogen.
Which of the factors is more related to biohazard risk assessment than the others? - Answer The
Pathogen and its risk classification
(The pathogen, the proposed procedures and the personnel who will be performing the work are three
core elements of risk assessment for biohazards.)
On the quick summary table of biocontainment or Biosafety Levels (BSL's), what is the lowest BSL that
recommends the use of a biological safety cabinet to contain aerosols based on risk assessment? -
Answer BSL2
(BSL2 is the first biosafety level or biocontainment level that recommends the use of a biosafety cabinet
to contain aerosols based on risk assessment.)
In Risk Group Comparison Table, Gwladys Caspars' quick guide statement of "don't touch it refers to
biohazards in which Risk Group? - Answer Risk Group 2
(Gwladys Caspar uses "don't touch it" to reference the likely ways a Risk Group 2 pathogen can enter the
body; through breaks in skin, or through non-intact skin and by contact of facial mucous membranes by
contaminated hands (or via direct splashing to these areas).)
Mycobacterium tuberculosis, a human pathogen with an inhalation route of exposure, a low infectious
dose and is capable of causing severe disease, including death, is representative of which Risk Group? -
Answer Risk Group 3
(Mycobacterium tuberculosis is a Risk Group 3 pathogen, that can be transmitted via the airborne route,
and has an infectious dose of 10 and can kill up to 50% of those who do not receive treatment.)
, How many Biosafety Levels have been created to outline recommended biocontainment practices and
laboratory design considerations? - Answer 4
(There are four Biosafety Levels for the safe handling and containment of biohazards: Biosafety Level 1,
2, 3 and 4. Biosafety Level 1 is for those microorganisms and other materials that require the least
amount of containment. BSL4 is reserved for those biohazards that require the most stringent
biocontainment.)
What is the lowest BSL that requires all manipulations of biohazards to take place within biological safety
cabinets or other primary containment enclosures? - Answer BSL3
(What is the lowest BSL that requires all manipulations of biohazards to take place within biological
safety cabinets or other primary containment enclosures?)
This BSL requires the use of a supply line respirator or all work within a sealed totally enclosed glove box.
- Answer BSL4
(BSL4 is the biocontainment level that requires either a encapsulated suit with a supply airline respirator
or all work with sealed Class III Glove Boxes.)
The number of laboratory-acquired infections is best described as? - Answer Greater than 5,000
laboratory-acquired infections have been documented.
According to this module, which statement regarding exposures in the laboratory to biohazards is
accurate? - Answer Have led to secondary infections of those who don't work inside the laboratory.
Which of the following statements is accurate regarding laboratory-acquired infections? - Answer Not
all laboratory-acquired infections have an identified route of exposure.
Which of the following statements regarding laboratory-acquired infections is not true? - Answer
Researchers handling human pathogens have never been infected with an agent as a result of an
exposure in the laboratory
