Q

process of risk assessment

A

identify hazard/threat –> determine consequence

25
type of cabinets
fume hood, laminar flow cabinet (LFC), Biohazard safety cabinet (BSC)
26
* Removes toxic chemical
FUME HOODS
27
No HEPA filter -> not for biohazard agents
fume hoods
28
Product protection (no personnel protection)
Laminar Flow Cabinets
29
Not for biohazard agents or chemical fumes
laminar flow cabinet
30
Class I BSC:
Personnel and Environment Protection
31
Class II & III BSC:
Personnel, Product and Environment Protection
32
BSCs provide ----- for work with -----material or --------- when they are properly maintained and used in conjunction with good laboratory technique
Biological safety cabinet
33
Personnel protection is provided through a continuous stream of inward air, known as
inflow
34
helps prevent aerosol from escaping through front opening
inflow
35
exhaust air is exhausted into
surrounding containment zone or directly to atmosphere
36
air is ---- to protect the environment
hepa-filtered
37
HEPA stands for
High Efficiency Particulate Air
38
ULPA stands for
ULPA: Ultra Low Penetration Air
39
- HEPA: 99.99% - at ?? microns
0.3
40
- ULPA: 99.999% - at ----??
0.12 microns
41
The “classical” definition of HEPA filter is 99.97% at 0.12 microns, but nowadays all BSC and LF in US use 99.99% at 0.3 m. T OR F
FALSE. The “classical” definition of HEPA filter is 99.97% at 0.3 microns, but nowadays all BSC and LF in US use 99.99% at 0.3 m
42
Removes a broad range of airborne contaminants:
HEPA/ULPA Capability
43
impurity ion can affect
integrated circuit speed
44
specialized clothing or equipment worn by an employee to provide protection against a hazard (e.g., infectious agents and toxins).
PPE
45
completely isolates the employee from the laboratory environment.
Biosafety level 4 positive pressure suit
46
The use of specific PPE required is determined through a
risk assessment
47
determines the type of ppe required
characteristics of the infectious agent or toxin being manipulated and the type of laboratory procedures performed
48
If there is a risk of creating an infectious biological aerosol (suspension of very fine particles or droplets in the air), use of
the proper respirator will prevent the worker from inhaling the infectious aerosol. This work can also be conducted in a biosafety cabinet to contain any aerosols created.
49
Describes microscopic droplets that may contain infectious agents or toxins, similar to the droplets produced by a sneeze or a cough.
aerosol
50
Some laboratory procedures including -------, ------, --------, -------------------and ---------can produce aerosols.
Some laboratory procedures including sonication, centrifugation, vortexing, flow cytometry, fluorescence-activated cell sorting (FACS) and homogenization can produce aerosols.
