OSHA 29 CFR , which applies to the transmission, distribution, and generation of electricity, cites ASTM F shoes in the standards. ASTM F – Standard Specification for Dielectric Footwear has been updated. This specification covers acceptance testing of dielectric. All of Salisbury’s ASTM Dielectric Footwear conforms with ASTM F and all are % tested to the electrical hazard requirements of ASTM F at 20,

ASTM Dielectric Footwear
Only one boot and overshoe currently meets the F specification. The differences between the standards are not usually understood, even by electrical specialists.
Dielectric or Satm Hazard levels. When it comes to OSHA recordkeeping there are always questions regarding the requirements and in and outs. This is not usually acceptable for wet service or higher voltages. The ASTM F standard covers minimum requirements for the design, performance, testing, and classification of protective footwear.
ASTM F1117 Dielectric
Which Standard Do I Choose? Also, look closely at the heel and sole design. Second, choose the standard: An example of ASTM style markings for protective footwear is: He is the senior managing partner and co-founder of e-Hazard, a leading electrical safety training and consulting firm, and the founder of ArcWear, which does 90 precent of the world’s arc flash testing of protective apparel. This specification covers acceptance testing of dielectric overfoot and overshoe footwear designed to provide additional isolation or insulation of workers if in accidental contact with energized electrical conductors, apparatus, or circuits.
ASTM F Reapproved is the f11177 for dielectric footwear and is a quite stringent standard. Problems to Consider Most testing applies only to the sole of the footwear, which usually begins degrading quickly.
The insulating protection of electrical hazard, safety-toe shoes may be compromised if the shoes become wet, the soles are worn through, metal particles become embedded astj the sole or heel, or workers touch conductive, grounded items.
Each article of overshoe footwear shall be given a proof test and shall axtm the Hz ac proof-test voltage rms value or the dc proof-test voltage average value. In-use standards normally require re-testing, so shoes should never be relied on as primary protection. Few guidelines exist on when and where to use the shoes in either standard.
All manufacturers and users recommend regular visual inspections and replacement when any sign of excessive wear exists. C denotes compression resistance and the compression resistance rating 75 or 50, which correlate to 2, pounds and 1, pounds of compression, respectively.
It is informational only and not an official part of the standard; r1117 full text of the standard itself must be referred to for its use and application. It is better in the sense that it does make use mandatory in a few cases but is still unclear about aatm role, if any, for EH shoes. Insulated soles shall not be used as primary electrical protection. The CSA standard is also a “wet sole test.
ASTM F – 14a Standard Test Method for Determining Dielectric Strength of Dielectric Footwear
Styles of overshoe footwear covered under this specification shall be designated as: This abstract is a brief summary of the referenced standard. Rubbers, designed to be worn over existing footwear and to cover only the foot of the worker; Boots, designed to be worn over existing footwear and to cover the foot and lower leg of the worker to below the knee; and Galoshes, designed to be worn over existing footwear and to cover the foot and lower leg of the worker to below the knee and having fasteners to close the folded front flaps.
Some dielectric shoes cannot pass the compression portion of that standard because many are designed as overshoes and don’t have a steel toe, but the overshoes can be worn with compression-resistant shoes if needed. Only dielectric footwear is listed in Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The most important thing to be aware of is that ASTM F is a standard designed primarily for impact and compression protection.
Fit and the ease of donning and doffing the footwear warrant consideration, especially on overshoes. Summary With OSHA early documents falling on the side of EH shoes for electrical work, companies would do well to consider them for all electrical workers and other workers exposed to electrical hazards or damp locations.
To purchase ASTM standards, see http: By Hugh Hoagland Apr 01, There are two basic names for shoes that have some protection from electrical shock: The outsole can provide a secondary electrical shock resistance protection to the wearer against the hazards from an incidental contact with energized electrical circuits or parts.
