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,

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 asfm the sole or heel, or workers touch conductive, grounded items. Second, choose the standard: The ASTM F standard covers minimum requirements f1117 the design, performance, testing, and classification of protective footwear. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Using Dielectric and Electrical Hazard Shoes — Occupational Health & Safety

One shoe of each pair must be clearly and legibly marked stitched in, stamped on, pressure sensitive label, etc. The last two lines are used to identify footwear made to offer protection from other specific types of hazards referenced in the standard. Third and optional fourth line: By Hugh Hoagland Apr 01, There are two basic names for shoes that have some protection from electrical shock: It is better in the sense that it does make use mandatory in a few cases but is still unclear about the role, if any, for EH shoes.

Dielectric DI Shoes ” These shoes can protect against open circuits of up to volts in dry conditions and should be used in conjunction with other insulating equipment and additional precautions to reduce the risk of a worker becoming a path for hazardous electrical energy. All manufacturers and users recommend regular visual inspections and replacement when any sign of excessive wear exists.

When it comes to OSHA recordkeeping there are always questions regarding the requirements and in and outs. Dielectric or Electrical Hazard levels. Only dielectric footwear is listed in This is not usually acceptable for wet service or higher voltages.


This paper offers some assistance on which standards relate to which shoes.

ASTM F1117 Dielectric

An example of ASTM style markings for protective footwear is: 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. Where insulated footwear is used as protection against step and touch potential, r1117 overshoes shall be required.

The most important thing to be aware of is that ASTM F is a standard designed primarily for impact and compression protection. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Fit and the ease of donning and doffing the footwear warrant consideration, especially on overshoes. Styles of overshoe footwear covered under this specification shall be designated as: In-use standards normally require re-testing, so shoes should never be relied on as primary protection.

High-risk tasks, environments, and medium and high voltages require more and more stable protection.

ASTM Dielectric Footwear

Steel toes have never been shown to conduct electricity as long as the toe is still covered with the shoe material. First, choose the protection level or specific standard you need: 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.

Historical Version s – view previous versions of standard. Only one boot and overshoe currently meets the F specification. This abstract is a brief summary of the referenced standard.

The last line is used only when more than three aetm apply.

M in this case means the footwear is designed for a Male F would be Female. The differences between the standards are not usually understood, even by electrical specialists.

A deep heel is needed to climb safely, while the normal shallow heel works well for walking. Using Dielectric and Electrical Hazard Shoes Minute holes in the soles of the footwear are the biggest area of concern in the protection scenarios.


The makers and users of dielectric shoes point out this fact. I denotes impact resistance followed by the impact resistance rating 75 or 50 in foot-pounds.

Which Standard Do I Choose? It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. It has three procedures that differ according to the section of the footwear tested. They designate conductive Cd properties, electrical insulation properties EHstatic electricity dissipative SDpuncture resistance PRchainsaw cut resistance CSand dielectric insulation DIif applicable.

IndustrySafe is here to help.

In asrm voltages or higher risks Each article of overshoe footwear shall be given a proof test and shall withstand the Hz ac proof-test voltage rms value or the dc proof-test voltage average value.

This is especially true for climbing poles, ladders, and stairs. ASTM F Reapproved is the specification for dielectric footwear and is a quite stringent standard.

Nonconductive footwear must not be used in explosive or hazardous locations. IndustrySafe Safety Management Software helps organizations to improve safety by providing a comprehensive toolset of software modules to help businesses identify trouble spots; reduce claims, lost days, OSHA fines; and more. To purchase ASTM standards, see http: 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.

An OSHA interpretation letter from March 17,basically does not “require” electrical trades to wear “safety toed shoes. They also note that some utilities attempt to astmm the chances of sole degradation by stamping a date on the footwear and replacing them after one year or less, depending on the frequency of use.
