What is the Chain of Custody?
Chain of custody documentation
For your tests to be evidential, you need to follow certain rules. Place the sealed vial along with the Chain of Custody document in a sealed package and send by Recorded Delivery to our laboratory. If you don’t already have these, we will include them with the pack.
ORAL TEST – After conducting the rapid test, the vial still contains the remains of the oral fluid. Put this in one of our despatch boxes, put this in an evidence bag, sign and retain the identity slip, and post the whole package.
URINE TESTS – If you use an integrated cup, simply post the cup and its contents to us in an evidence bag. If you use a standard cup, decant the liquid into two vials and place these in the evidence bag, and post the whole package.
HAIR TESTS – The hair test collection kit contains all you need to collect the sample and send it to us in the evidence kit.
EVIDENCE BAGS – These come in several shapes and sizes, but some we have found are a heat sealed sleeve, which can be cut open and simply resealed. These are not secure. Our bags are a little more expensive but they are folded bags with a crease at the bottom. The sides are sealed and overprinted so they cannot possibly be tampered with. Again, it pays to be buying from the experts in this field.
ALCOHOL – For many companies, alcohol abuse is still a problem, and is complicated by case law that controls what action you may take. Those companies employing at-risk workers such as scaffolders, drivers, and machinists need to take a harder line than those employing office workers.
For more frequent use we recommend our digital alcohol meter. Although it is inexpensive it is very accurate and is calibrated to breath levels. The legal limit in Britain is 35 microgrammes per 100 ml of breath.
SOLVENTS – Solvent abuse is not usually a problem at work, but anyone found who is thought to be under the influence should receive immediate medical attention.
