To use the wipe, tear open the packet, remove the towelette, and squeeze the contents directly into the eyes. Then use the towelette to thoroughly wipe exposed areas. Ingredients in the wipe soak up the chemical agents from the skin, greatly reducing the normal decontamination time. Sudecon wipes are also great for cleaning up any hard surface that may contain errant irritants.
If you are carrying a Byrna or any chemical defense product, make sure a Sudecon wipe is within easy reach so that if the time comes, you are prepared to defend.
