This barrier tape will quickly identify the three important zones in a decontamination situation. The Hot Zone is the contaminated area, the warm zone is where the decontamination operation is set up, and the cold zone is for post-decontamination treatment or command post. The tape is lightweight, but strong enough to be reused many times. Deploy rapidly by wrapping around trees, poles, and barrels; or it can be secured to walls or barricades.
