Arc-rated liner for hard hats
The Occunomix LP690 is a flame-resistant liner that attaches to a hard hat and carries an ATPV rating of 21 cal/cm². It meets Arc Flash PPE Category 2 and complies with ASTM F1506 and NFPA 70E for workers exposed to electric-arc hazards.
Replaces non-rated liners when Category 2
The jump is worth it when a task demands Arc Flash PPE Category 2 and the current liner lacks an ATPV rating or falls below 21 cal/cm². It is not for buyers who need Category 3 or 4 protection or who require a liner certified to a different arc-rating standard.
Cotton and modacrylic blend maintains protection
The 6 oz fabric uses a cotton and modacrylic blend with a hook-and-loop closure and tabs that stay secure during long shifts. Horizontal reflective strip on the back and warming-pack pockets support visibility and comfort in cold conditions without degrading the arc rating.

Questions about this item
Does the LP690 liner fit a standard hard hat with hook-and-loop tabs?
Yes, the liner includes hook-and-loop closure and tabs designed to attach to a hard hat for secure mounting.
How do I install the liner on my hard hat, and what step is often missed?
Align the tabs with the hard hat suspension points, press the hook-and-loop strips firmly together, and ensure the reflective strip sits centered at the back above the neck for proper orientation.
When should I replace the liner to maintain its 21 cal/cm² ATPV rating?
Replace the liner if the cotton-modacrylic fabric shows wear, contamination, or damage, or after any arc flash exposure, as degradation reduces the Arc protection level.
