We’ve received reports from a number of organizers who have suffered problems after wearing duct tape on their mouths. As a consequence we feel it is important to address this safety issue. While we have never encouraged nor endorsed wearing duct tape for the Day of Silence, we recognize that the symbolism of putting duct tape over the mouth has become quite popular amongst some DOS organizers. Duct tape uses a very strong, water-resistant adhesive. When students attempt to take off the tape we have heard about a range of problems.
