3M Scotch Buried Barricade Tape 302 - Clear Warning for Buried

Our review of the 3M Scotch Buried Barricade Tape 302 finds it best suited for contractors, utility crews, and site managers who need a dependable buried warning tape to reduce accidental digs near electrical lines. The single biggest reason to buy is its highly visible red polyethylene film and bold 2 in black CAUTION lettering printed with opaque, nontransferable ink, which provides a clear, durable warning when buried above electrical lines. In practice it signals danger to future excavators and helps protect equipment and people from accidental contact with buried conductors.

Key Features

• Bold warning text: Large 2 in black CAUTION characters on a red background deliver immediate visibility when the tape is uncovered.
• Durable construction: Four-mil polyethylene film resists accidental tearing so the warning remains intact in backfill conditions.
• Nontransferable ink: Opaque ink prevents the warning from rubbing off onto other materials during handling or burial.
• Wide temperature range: Rated for application from 32F to 120F (0C to 49C), allowing installation in most jobsite climates.
• Purpose-built use: Designed to be buried above electrical lines to alert future diggers and reduce the risk of damage and injury.
• Regulatory compliance: Available tape options and widths meet RoHS 2011/65/EU compliance for many industrial sites.

Who It's For

This tape is aimed at professional audiences: electricians, trenching contractors, municipalities, and utility crews who routinely mark buried electrical utilities. The clear CAUTION BURIED ELECTRIC LINE message is tailored for job sites where permanent, visible warnings are required above buried conductors.

It is not intended for casual or household use; packaging and labeling note it is for industrial and occupational use only. Home DIYers who need decorative or temporary marking tape should look for consumer-rated products instead.
