Barrier tape (also known as caution or barricade tape) is a high-visibility, non-adhesive plastic ribbon used to cordon off specific areas. It serves as a visual warning to prevent people from entering hazardous zones or restricted areas.
Key Features
- Material: Typically made of durable, weather-resistant polyethylene (plastic).
- Colors: High-contrast combinations like Yellow/Black (general caution) or Red/White (immediate danger/fire equipment).
- Function: It is a passive safety device; it doesn’t provide a physical block but communicates a clear “do not cross” message.
