- 99.7% effective
A: 99.97% effective for particles 0.3 microns or larger

Q: Please select the correct answer for the question.

Friable asbestos-containing materials pose a greater health hazard then non-friable asbestos containing materials, because they:

- have a greater potential for fiber release
- don't wet as easily with amended water
- contain more asbestos
A: have a greater potential for fiber release
