Part of the standard decontamination kit issued to British soldiers included a small puffer bottle of fullers earth that could be sprayed on a soldier’s equipment to soak up chemical agents. These little bottles were carried in a soldier’s NBC haversack and can be found with varying colours of both the powder and the stopper cap:When the DKP2 was issued it came in a heat sealed plastic bag to keep it safe from contaminants:Wrapped around the bottle is a paper instruction sheet:The top of the packet has a V-notch to help the user rip open the packet, even when wearing gloves:The 1983 copy of Survive to Fight explained how to use the DKP2:
You are issued with the DKP2 which is a plastic puffer bottle containing fullers earth and is used to force fullers earth powder into places that are inaccessible to the DKP1 pad. The DKP2 is well suited to the decontamination of your webbing and over boots but it is recommended that the powder from the puffer bottle is rubbed in using a DKP1, or your gloved hand.Kevin Mervin served in the TA and describes using the DKP2 bottle during training:
We had to blot, bang, rub the two inch pad of the DKP powder over our heads, respirators and gloves to soak up any chemical agent. We then used the DKP2 puffer bottle to decontaminate our Kevlar helmets, overboots and surrounding ground.
One interesting reference I have found is to troops using old DKP2 bottles to carry lubricating oil for their weapons, the design being able to be slipped into a pocket and brought out to oil their weapon quickly when they haven’t time to get the full cleaning kit out.
