Swabbing Kit for Sampling Suspects for Firearms and Explosives Residue
The kit is divided into three compartments within a nylon outer bag and contains all the necessary components and materials needed to ensure an efficient recovery of residues from a suspect.
The first compartment contains detailed instructions, a medi wipe and a ball point pen. The second section contains a disposable overall and pair of gloves to be worn by the sampling officer. The third section contains the sampling materials in a rigid plastic container with spare security lid and other packaging materials for re-submission.
The comprehensive instructions guide the sampling officer through the steps of the sampling process and act as a set of contemporaneous notes for evidence of correct sampling. Two of the swabs contained in the kit are used for swabbing the sampling officer and work surface prior to sampling the test subject. These are used as controls to ensure the cleanliness of the sampling officer and the room in which the sampling is performed. The swabs are made from a piece of acrilan fibre, moistened with a solvent (isopropanol) and contained in a polythene lined foil sachet. This is torn open and while wearing gloves, is firmly rubbed over the test surface and then placed into a capped plastic tube. The test subjects hands, face and hair are all sampled with separate swabs. These are retained in separate labelled plastic bags and then sealed in the plastic container for submission to the laboratory.
The precautions incorporated in these kits play a significant role in negating cross contamination claims arising from the sampling procedure. The quality of these kits is controlled by strict preparation and packaging processes and can be demonstrated by reference to quality control samples taken during the course of the preparation.
