CONDUCTIVE SPARKPROOF FLOORING
**************************************************************************
NOTE: Conductive floors will be used at operations
where explosives having an electrostatic sensitivity
of 0.1 joule or less such as primer, detonator,
igniter, and incendiary mixtures are exposed.
Conductive floors are also required where the
following are performed:
a. Loose unpacked ammo with electric primers.
b. Exposed electro-explosive devices.
c. Electrically initiated items with exposed
electric circuitry.
d. Hazardous materials that could be ignited by
static discharge from humans.
**************************************************************************
Conductive sparkproof industrial resin-based flooring system shall be
trowel or spray applied [1.6 mm 1/16 inch] [3 mm 1/8 inch] [6 mm 1/4 inch]
thick, epoxy, polyester, or other resinous material conforming to ASTM C 722
with [Type A surfacings (chemical resistance and moderate to heavy traffic
resistance)] [Type B surfacings (mild chemical resistance and severe
thermal shock stability)]. Conductive flooring shall be grounded and shall
conform to the requirements for conductive flooring of NFPA 99.
