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

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 10 According to CSI Byrd in his article “Hazards
and a crime scene,” what are the three (3) types of general hazards
