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.

纵火，或“恶意和故意，或鲁莽，纵火或引起爆炸的犯罪”，是最具挑战性的犯罪调查之一。就其本质而言，火灾会消耗现场的材料，** 并会掩盖或破坏证据。消防员在现场喷水和/或泡沫以及救援人员的移动使调查工作更加复杂，这可能会将证据从其来源传播到整个现场的其他地点。在涉嫌纵火案中，化学证据的一个关键部分是在现场鉴定外来易燃液体 **（如汽油）。这是通过使用调查技术来确定火灾现场的重要区域以从中提取样本来实现的。一旦收集到样品，就将其运送到 ** 实验室进行分析。Global Forensics（GF）是一家艾伯塔公司，在民事和刑事案件中提供一系列法医调查服务，特别是在火灾和爆炸领域。在火灾调查中，** 他们看到证据和证据容器受到污染的全系统问题。该研究项目 ** 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。这些做法将成为全球法医提供的火灾调查培训课程的一部分。
