Survey of Forensic Science Laboratories
by the Technical Working Group for Fire and Explosions (TWGFEX)
Survey
Text
Instructions: The following survey contains questions
related to your job responsibilities, education, training, laboratory
standards and protocol, and information resources. It should
take about 20 minutes to complete. Most items can be answered
by both fire debris and explosives analysts, although some items,
where indicated, will be applicable to, and should only be answered
by, one group. This survey does ask for your name and laboratory.
Providing this information is optional and requested only to
ensure that in the event a second mailing of the survey is done,
those who have already completed the survey will not receive
a second copy. All information you provide on your survey will
be treated with the utmost confidentiality. Thank you for your
participation.
