6 FAQs about [An evidence container should be filled with solid debris]
How should evidence containers be sealed?
All evidence containers should be properly sealed to prevent escape of vapors and properly identified and marked. Each evidence container should be properly protected from physical damage and packed securely in the shipping box. Seal the shipping box and mark "evidence" on it.
How do I collect evidence from a fire?
Solids: Collect evidence in clean unused airtight containers such as metal cans, glass jars, or heat-sealed bags recommended for fire debris (e.g. nylon or Kapak bags that are designed for fire debris) and seal. Contact the laboratory for questions regarding the use of Kapak bags.
Why should evidence be sealed in an airtight container?
Evidence also may be contaminated and/or lost by exposure to the atmosphere; thus, it must be sealed in an airtight container. It also may be contaminated by an improper evidence container. Flammable vapors may deteriorate portions of containers, at the seam of metal containers or the rubber seals of lids on glass containers.
Do evidence containers interfere with chromatography?
New, unused evidence containers. Most evidence containers yield no chromatographic interference. However, some types of containers, like certain types of plastic bags and specially coated containers, may give off background vapors which can obscure chromatographic analysis of evidence.
How should ignitable liquid residue be collected at a fire scene?
To achieve the best laboratory results, samples suspected of containing ignitable liquid residue should always be collected and packaged into an evidence can in a way that permits volatiles to migrate and gather in the head space. Following a few basic procedures at the fire scene will facilitate this process.
Should a comparison sample be collected for a fire debris sample?
A comparison sample should be collected for every questioned fire debris sample. Absorbent materials for controlling petroleum spills are unsuitable for evidence collection because they have been found to contain traces of contaminants. Comparable accelerant samples.
