investigator may be susceptible to at a crime scene? List an example of each.

begins with implementation of OSHA’s BBP standard, 40 CFR 1910.1030. What is
OSHA and why is it necessary to understand this BBP standard?
Question 9 List at least three (3) general wavelengths that
are utilized with an ALS to visualize evidence. Give an example of the types of
evidence that can be visualized with each of these wavelengths.

Question 18 Crime scene investigator Davies is collecting
fiber evidence from a death investigation case. She notices fibers on the
victim’s shirt and pants. She places both of these fibers in a plastic bag. She
then sees fibers on a sheet near the victim so she folds the sheet into itself
and places it carefully into a different plastic bag. Finally, noticing fibers
