The barrier tape known as "safety tape" is designed to prevent accidents. It is widely used to warn people to avoid regions where there is a possible safety threat or hazard. For instance, it could be used to barricade a construction site's entrance to a hazardous area or an abandoned structure.

In more everyday situations, such as to mark a moist area of the floor where people might trip if they step, this tape can also be utilized. In case they need to keep kids out of a specific area, teachers may wish to carry caution tape in their necessary supply list for school supplies.
