Study of packaging and contamination of fire debris exhibits

纵火，或“恶意、故意或鲁莽地纵火或引发爆炸的罪行”，是**最具挑战性的犯罪之一。就其本质而言，火灾会消耗现场的材料，**并会掩盖或摧毁证据。由于消防员在现场喷洒水和/或**泡沫，以及救援人员的行动，调查变得更加复杂，这可能会将证据从来源传播到整个现场的其他**地点。**涉嫌纵火的化学证据之一是在现场识别外国易燃液体**(例如汽油)。这是通过使用调查技术来确定火灾现场要采集样本的重要**区域来实现的。样本一旦采集，就被送到**实验室进行分析。**Global Forensics(GF)是艾伯塔省的一家公司，在**民事和刑事案件中提供一系列法医调查服务，尤其是在火灾和爆炸领域。在火灾调查方面，**他们看到了证据和证据容器污染的全系统问题。这项研究项目**旨在查明相关污染源，并制定防止污染的最佳做法，**从而确保样本和调查的完整性。这些做法将成为Global Forensics提供的火灾**调查培训课程的一部分。

Arson, or "the crime of maliciously and intentionally, or recklessly, starting a fire or causing an explosion," is**one of the most challenging crimes to investigate. By their very nature, fires consume materials at the scene,**and will obscure or destroy evidence. Investigation is further complicated by firefighters spraying water and/or**foams on the scene and the movements of rescue personnel, which can spread evidence from its origin to other**locations throughout the scene.**One of the key pieces of chemical evidence in suspected arsons is the identification of foreign ignitable liquids**(e.g. gasoline) at the scene. This is accomplished by using investigative techniques to identify important**regions of the fire scene from which to take samples. Once samples are collected, they are transported to a**laboratory for analysis.**Global Forensics (GF) is an Albertan company providing a range of forensic investigative services in both**civil and criminal matters, most notably in the area of fires and explosions. In the context of fire investigations,**they see system-wide issues with the contamination of evidence and evidence containers. This research project**aims to identify relevant sources of contamination and develop best practices for preventing contamination,**thus ensuring the integrity of samples and investigations. These practices will then become part of the fire**investigation training courses that Global Forensics provides.
