Electrical-Grade Dielectric Switchboard Matting, ASTM D 178, OSHA 29 CFR 1910.137, is a floor matting product, which is used to insulate workers from electrocution by interrupting the path to ground. Switchboard Matting is typically used around electrified equipment where operational and maintenance workers stand.
ASTM D178 is the specification used for Switchboard Matting in industrial and manufacturing environments. It is also used by Naval Facilities Engineering Command (NAVFAC) and Naval Public Works Facilities (NAVPWC) in US Navy industrial applications, and other Department of Defense and US Government agencies.
Switchboard Matting is manufactured from dielectric materials, which are electrically non-conductive. The dielectric strength of the matting is defined, in the specification, by various Types and Classes.
Dielectric Switchboard Matting, ASTMD 178, protects workers in way of low, medium and high voltage electrical potentials, as outlined in the specification. Its Corrugated (ribbed) surface provides a comfortable, resilient, anti-fatigue type surface to stand on.

ASTM The American Society for Testing Materials (ASTM) is the author of the specification ASTM D 178-01. ASTM is the Recognized Standards Authority in the USA, and other countries, for dielectric switchboard matting used in industrial environments.
OSHA OSHA has defined Switchboard Matting as Personal Protective Equipment (PPE) in the Code of Federal Regulations, 29 CFR 1910.137 Electrical Protective Devices, and recommends the use of ASTM D 178 matting.
OSHA has defined Yellow as the basic color for designating Caution in the Code of Federal Regulations, 29 CFR 1910.144 Safety Color Code For Marking Physical Hazards and recommends Yellow for designating or marking physical hazards such as stumbling, falling and tripping.
Also see OSHA, Code of Federal Regulations, 29 CFR 1910.269, Appendix C, Special Industries, Protection from Step and Touch Potentials for additional information.
Quality Assurance Purchase Orders for Switchboard Matting, ASTM D 178, should require written Certification to the CurrentRevision of the specification. Certificates should be readily available to OSHA, Risk Management and Insurance Company inspection personnel.
