Caution tape5/23/2023 ![]() Because of this, it's commonly used for industrial materials, just like barricade tape. Unlike other harder plastics, it can change shape under impact and can stretch or twist without breaking. Polyethylene is a specific kind of plastic which has high ductility and impact strength. Perhaps you've noticed that most of these tapes have been described as "polyethylene", but what is polyethylene? An example of the messaging on this kind of tape would be “Gas Line Below”. While they're often made from polyethylene just like barricade tape, they can be in any color which might catch an excavator's attention. These tapes are called "non detectable underground tape". Underground Tape: Sometimes gas lines or other underground risks must be marked with tape in case of excavation, but do not need to be visible from the surface.This makes it clear that the police may be in and out of the perimeter, but pedestrians and passers by should steer clear. For instance the police may secure the perimeter with tape containing messages like “ Crime Scene - Do Not Cross ” or “Police Line - Do Not Cross”. Yellow Crime Scene and Police Tape: Sometimes crime scene perimeters are barricaded off with yellow tape, but the messaging is explicit.Here are some of the other common barricade tapes one might see: These are the most common instances of polyethylene barricade caution tapes. Red tape for instance might say “ Danger - Do Not Enter ” instead of "Caution - Do Not Enter". Danger Tape: Danger tape uses black lettering on top of a r ed polyethylene ribbon instead. The messaging in these cases usually includes the word "Danger" and is meant to escalate the level of warning which might exist with the yellow caution tape alternative. While caution tape is probably used where some risk is present, danger tape is used when there's a more serious risk of hazard.This could include messages like “ Caution - Do Not Enter ” and “ Caution - No Parking ”. Some caution tape takes advantage of the high contrast of black and yellow with diagonal stripes that catch the attention, but otherwise has no messaging at all. ![]()
