Asbestos Flashcards
1
Q
What the different methods one can analyze fibers?
A
- Phase contrast microscopy (PCM)
- Polarized light microscopy (PLM)
- Electron microscopy
- Scanning electron microscopy (SEM)
- Transmission electron microscopy (TEM)
1
Q
What method can you use to sample bulk asbestos fibers?
A
PLM and TEM
2
Q
Way to remember phase contrast microscopy
A
Pretty cheap microscopy
3
Q
Does PLM work on all types of asbestos?
A
No - only friable asbestos
4
Q
Way to remember SEM and TEM
A
Super expensive microscopy, terribly expensive microscopy
5
Q
What type of analysis do you do when performing a clearance sample?
A
SEM and TEM
6
Q
PCM
A
- Phase contrast microscopy (pretty cheap microscopy)
- PCM does not differentiate between asbestos and other fibers.
7
Q
PLM
A
Polarized light microscopy. Only works for bulk samples. PLM Only really works for friable asbestos.
8
Q
TEM
A
- Transmission electron microscopy (terribly expensive microscopy)
- Necessary for asbestos clear out samples
