3M 7000133193 Scotch® Detectable Buried Barricade Tape 409, CAUTION BURIED FIBER OPTIC LINE BELOW, 6 in x 1000 ft, Orange, 4 rolls/Case

Yes. The Scotch 409 detectable buried barricade tape uses an aluminum foil backing carrier, which is what makes it traceable with standard inductive or conductive locating equipment once it's in the trench. That's the difference between this and plain non-detectable warning tape, which only helps someone who has already opened the ground.

No. The legend on this roll reads CAUTION BURIED FIBER OPTIC LINE BELOW and the tape is orange, the APWA communication color. For a power feeder you need red tape with an electric-line legend. Marking a power run with orange fiber tape misleads the next crew that opens the ground, which is the whole reason the tape is there.

It's non-adhesive. The 409 is laid loose in the trench above the line, not wrapped or stuck to anything. If you need to join two runs, overlap the ends and cover with backfill, or use a separate tape for the splice; nothing on the tape itself will bond.

Each roll runs 1000 ft (304.8 m) at 6 in (152.4 mm) wide, and the case holds four rolls, so figure 4000 linear feet of trench per case laid in a single run.

The backing is treated so the APWA color won't fade or break down from exposure to alkalis and acids, which covers most backfill and soil conditions. Total tape thickness is 5.0 mil (0.13 mm) with a rated tensile strength of 15000, so it takes the pull of being rolled out and covered without tearing off the reel.

The stated service range for the 409 is 0 to 120 F (0 to 49 C). Below freezing is outside that range, so a winter trench in hard frost is not a condition the tape is rated for. Schedule the lay-in above 0 F.

At 6 in (152.4 mm) wide, the 409 gives a broad visual band across the trench, which is what you want when the excavation may be reopened years later by someone who has no drawings. Narrower widths are usually chosen for tight trenches or small-diameter conduit runs where 6 inches would fold over on itself. For a fiber backbone under a parking lot or roadway, the wider band is the safer call.

Yes, the 409 is compliant with RoHS 2011/65/EU. 3M also publishes a regulatory data sheet and an article information sheet for the product if your submittal package needs the documentation on file.
