During a major incident in your jurisdiction, the last thing you need is an unruly crowd or unprotected crime scene or biohazard incident. Our barrier tape is three inches wide and 1000 feet long with black letters printed on 4 mil polyethylene. All rolls are bright yellow in color, except the "Caution: Biohazard" barrier tape, which is orange-red. Each roll comes in a heavy-duty cardboard dispenser box for storage and ease in handling.
