KLUBSY: LABORATORY SAFETY Flashcards
(98 cards)
Used to remove particles that may be harmful to the employee who is working with potentially infectious biologic specimens
Biosafety cabinets (BSCs)
This must be used when performing procedures that generate
infectious aerosols
BSC
For BSC Class I, what is its face velocity?
75
for BSC Class II, A1, what is its face velocity?
75
For BSC Class II, A2, what is its face velocity?
100
For BSC Class II, B2, what is its face velocity?
100
For BSC Class II B2, what is its face velocity?
100
In at front
through HЕРА
to the outside
or into the
room through
HEPA. What BSC Class is this?
BSC Class I
What is the airflow pattern for BSC Class II, A1?
R - 70%
E - 30%
*R for recirculated and E for exhausted
What is the airflow pattern for BSC Class II, A2?
R = 70%
E = 30%
What is the airflow pattern for BSC Class II, B1?
R = 30%
E = 70%
What is the airflow pattern of BSC Class II, B2?
No recirculation,
total exhaust
to outside. Therefore,
R = 0%
E = 100%
This BSC Class only exhausted air is filtered by HEPA filter
Class I
In this BSC Class, air entering and air exhausted is filtered
Class II
In this BSC Class, gloves are attached
Class III
These are required to contain and expel noxious and hazardous
fumes from chemical reagents
chemical fume hoods
used when working with some highly toxic and volatile
chemical
chemical fume hoods
a partially enclosed ventilated work space for volatile
chemicals
chemical fume hoods
T/F: Chemical fume hoods are used for storage of hazardous chemicals
FALSE.
NOT used
Chemical fume hoods Periodically evaluate what?
Periodically evaluate ventilation
Chemical fume hoods periodically evaluate ventilation by what?
by measuring face velocity
Chemical fume hoods periodically evaluate ventilation by measuring face velocity using a what?
with a calibrated velocity meter
Specialized clothing or equipment worn by an employee
for protection
Personnel protective equipment (PPE)
These PPE protect the hands and arms
when using caustic chemicals.
gloves and rubberized sleeves
