Explosives-area flooring and personnel controls
Craftsman Concrete Floors specializes in conductive floors for explosives operations. These projects require careful coordination of flooring, grounding connections, personnel footwear, and testing. Our ESD flooring services cover the flooring side of that work; the guides below help you find the relevant source requirements and focused technical answers.
Start with the document or operation named in your project. The explosives guides are organized by authority; the remaining guides cover liquid transfer, combustible dust, bulk bags, grounding verification, and related processes. Each guide identifies the source edition it discusses. Some focused answers compare more than one document.
Floor and tabletop resistance, conductive footwear, installation and periodic testing, and permitted substitutions under DoD Manual 4145.26 (2008, Change 2 of 2018).
Installation conditions, inspection schedules, resistance measurements, and operating controls under DA Pam 385-64 (24 July 2023).
Inspection responsibilities and intervals under AFMAN 32-1065 (17 July 2020), alongside the floor, cleaning, equipment-contact, and test-area provisions in DESR 6055.09_DAFMAN 91-201 (18 June 2025).
Flammable liquids, combustible dust, and bulk bags
A CSB tank-filling case study addresses static ignition during liquid transfer. The focused filling-point guide below covers a separate TRGS 727 provision.
Grounding during operation, filling, and emptying of dust-handling equipment, including vacuum equipment, containers, and dust separators, under the German technical rule TRGS 727.
Types of flexible intermediate bulk containers (FIBCs), the TRGS 727 selection table, liners, and nearby grounding duties. A separate Newson Gale section explains what Type C monitoring checks.

Frequently asked questions
The DoD and Army guides cover floor resistance provisions within their respective source scopes. The UFGS guide covers electrical-resistance and spark-resistance tests, while the TRGS 727 guide on limits by zone distinguishes floor and person-to-earth measurements.
The DoD and Army guides address flooring and personnel footwear. Focused answers cover the DoD combined resistance budget and the limits of a footwear-tester result described by Newson Gale.
The equipment-contact guide compares DoD and Army provisions. The wax-and-cleaning guide compares Army and DoD restrictions, while the test-area-clearance guide covers DoD and Army requirements. The Air Force guide brings together the related AFMAN and DAFMAN provisions. A separate Newson Gale guide discusses contamination at floor-contact grounding paths.
The flammable-liquid guide covers the CSB case study, with a separate TRGS 727 guide for rarely used filling points. The combustible-dust guide covers TRGS 727 equipment grounding, with focused answers on hoses and vacuum equipment.
