A small fan helps distribute the fumes, perhaps a little one outside the box - otherwise, it would get coated, too. If the CA chamber is used for successive batches of evidence immediately upon removing items from a prior cycle, the heat source will still be warm and the time of exposure may have to be changed to prevent over-fuming in the subsequent cycles. Iodine fuming is still widely used because it is inexpensive and easy, sensitive, and is non-destructive because the stains it produces are ephemeral. 10 The role of the fingerprint material in the process, leading to formation of methyl cyanoacrylate polymer at the site of the fingerprint, remains to be established.
