A lack of information concerning the potential recovery of fingerprints from fire scenes and related evidence prompted several research projects. Latent prints from good secretors and visible prints (in blood) were placed on a variety of different surfaces and subsequently subjected to "real life" fires in fully furnished compartments used for fire investigation training purposes. The items were placed in various locations and at different heights within the compartments. After some initial success, further tests were undertaken using both latent and dirt/grease marks on different objects within the same types of fire compartments. Subsequent sets of tests involved the recovery of latent and visual fingerprints (in blood, dirt and grease) from different types of weapons, lighters, plastic bags, match boxes, tapers, plastic bottles and petrol bombs that had been subjected to the same fire conditions as previously. Throughout the entire series of projects one of the prime considerations was how the resultant findings could be put into practice by fire scene examiners in an attempt to assist the police in their investigations. This research demonstrates that almost one in five items recovered from fire scenes yielded fingerprint ridge detail following normal development treatments.
由于缺乏关于能否从火灾现场提取指纹及相关证据的信息，促使了几个研究项目的开展。将来自良好分泌者的潜在指纹和可见指纹（血液中的）放置在各种不同表面上，随后在用于火灾调查培训目的的配备齐全的隔间中进行“真实场景”火灾实验。这些物品被放置在隔间内的不同位置和不同高度。在取得初步成功后，又在相同类型的火灾隔间内，对不同物体上的潜在指纹以及污垢/油脂痕迹进行了进一步测试。后续的一系列测试涉及从不同类型的武器、打火机、塑料袋、火柴盒、蜡烛、塑料瓶和汽油弹上提取潜在指纹和可见指纹（血液、污垢和油脂中的），这些物品都经历了与之前相同的火灾条件。在整个系列项目中，一个主要的考虑因素是火灾现场勘查人员如何将所得结果应用于实际工作中，以协助警方进行调查。这项研究表明，从火灾现场找回的物品中，几乎五分之一经过常规显影处理后能得到指纹纹路细节。
