Boundaries only work when everyone can see them.
Choosing marking materials
Standard floor tape can be insulative and shed adhesive in traffic. Where markings sit inside a grounded floor system, use tapes rated for dissipative floors so the boundary itself does not interrupt the path.
Paint lasts longer but complicates floor resistance testing later; many plants use tape for trial layouts and commit to paint only once the layout proves out.
FAQ
Do floor markings need their own resistance rating?
If the marking sits in a walking path that relies on floor grounding, yes. Check that tape or paint does not create an insulative island under foot traffic.
How wide should an EPA boundary line be?
Visibility beats any fixed number: lines that survive forklift traffic tend to be wider and recessed or taped under clear traffic rules.
How often should markings be re-audited?
Fold markings into the existing EPA audit: peeling tape and scuffed paint are small findings, but they reveal traffic patterns worth reviewing.
