ESD flooring for munitions and energetics

This is the one category where conductive flooring is mandatory rather than preferred. DESR 6055.09 names the rooms directly.[10]

Get a quote The governing document
ANSI/ESD S20.20 measures the person, their footwear and the floor as one circuit PERSONSHOES THE FLOOR, AND ITS PATH TO GROUND One circuit, measured end to end. Under 1.0 x 10⁹ ohms (STM97.1) Under 100 volts walking (STM97.2) Change the footwear and the reading changes, which is why the floor is never qualified alone.
S20.20 qualifies a system, not a surface. The person and their footwear are inside the measurement.

What is different about these rooms

01

The regulation names the areas

Ammunition load, assemble and pack. Explosives processing. Propellant casting. Pyrotechnic assembly. Energetics manufacturing. Conductive flooring is required in those rooms, not merely dissipative.

02

The hazard is the spark, not the part

In an energetics area a discharge is an ignition source. That is why the faster conductive band is specified instead of the gentler dissipative one.

03

Check the current regulation, not the predecessor

If your contract language cites DoD 4145.26-M, that is the predecessor document. The current regulation is DESR 6055.09, Edition 1 Change 2, dated 25 November 2025.
