BACTE LAB LA1

Question 1

Is a framework that describes the use of specific practices,
training, safety equipment, and specially designed buildings to protect the
worker, community, and environment from an accidental exposure or
unintentional release of infectious agents and toxins

Answer 1

BIOSAFETY

Question 2

include biological agents and toxins infectious to humans,
animals, wildlife, or plants such as parasites, viruses, bacteria, fungi, prions; and

Question 16

describes the use of biosafety principles and practices
in laboratories to reduce the health-related risks associated with handling
infectious agents, toxins and other biological hazards arising from an accidental
exposure or unintentional release

Answer 16

LABORATORY BIOSAFETY

Question 17

are designations applied to projects or activities
conducted in laboratories in ascending order of containment based on the
severity of the health-related risk associated with the work being conducted

Answer 17

BIOSAFETY LEVELS

Question 18

The appropriate BSL to be assigned to a project is determined by _______________ or professionals, and reflects the specific
combinations of specially designed buildings, safety equipment and safe work
practices that laboratory workers must use

Answer 18

institutional biosafety committees (IBCs)

Question 19

refers to the use of safety equipment and
specially designed rooms and buildings which act as primary barriers to prevent
the release of infectious agents, toxins, and other biological hazards into the
environment

Answer 19

LABORATORY BIOCONTAINMENT

Question 20

Examples of Primary biocontainment barriers include, but are not limited to:

Answer 20

o biosafety cabinets
o sealed containers such as containment centrifuges
o special animal caging systems

Question 21

Include specially designed and
constructed rooms and buildings. These buildings include several engineering features to keep, or “contain”, infectious agents, toxins, and biological hazards
inside the laboratory workspace

Answer 21

Secondary biocontainment barriers

Question 22

Secondary biocontainment barriers features include, but are
not limited to:

Answer 22

o sealed rooms;
o self-closing, lockable doors; and
o specialized air handling and decontamination systems

Question 23

is a term used to describe laboratories or facilities that
operate at Biosafety Level 3 (BSL-3) conditions

Answer 23

High containment

Question 24

is a term used to describe laboratories or facilities that operate at BSL-4 conditions.

Answer 24

“Maximum containment”

Question 25

is a combination of the likelihood of an exposure to an infectious
agent, toxin, or biological hazard that will cause harm, and the consequence,
or severity, of that harm if exposure does occur.

Answer 25

Biorisk

Question 26

is a process that evaluates multiple factors to
determine the risk to laboratory workers, the community, or the environment of
working with an infectious agent, toxin, or other biological hazard.

Answer 26

biological risk assessment

Question 27

used to determine the appropriate biosafety level for each project conducted within a laboratory

Answer 27

biological risk assessment

Question 28

are classifications of infectious
agents and toxins that identify the relative likelihood and severity of disease an
infectious agent or toxin can cause.

Answer 28

Risk groups

Question 29

healthy human adults

Answer 29

RISK GROUP 1

Question 30

organisms that may cause mild disease for which
medical countermeasures are available.

Answer 30

which medical countermeasures may be available, and which have
low potential to spread in the community or environment

Answer 31

RISK GROUP 3
