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,

They also note that some utilities attempt to lessen 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.
Using Dielectric and Electrical Hazard Shoes — Occupational Health & Safety
Where insulated footwear is used as protection against step and touch potential, dielectric overshoes shall be required. C denotes compression resistance and the compression resistance rating 75 or 50, which correlate to 2, pounds and 1, pounds of compression, respectively.
Problems to Consider Most testing applies only to the sole of the footwear, which usually begins degrading quickly. Testing ensures the materials are capable of withstanding 14, v at 60 Hz for one minute with no current flow or leakage current in excess of 3. Also, look closely at the heel and sole design.
In-use standards normally require re-testing, so shoes should never be relied on as primary protection. Which Standard Do I Asrm A deep heel is needed to climb safely, while the normal shallow heel works well aatm walking. Minute holes in the soles of the footwear are the biggest area of concern in the protection scenarios.
Historical Version s f117 view previous versions of standard. Third and optional fourth line: Styles of overshoe footwear covered under this specification shall be designated as: The differences between the standards are not usually understood, even by electrical specialists. 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.
Second, choose the standard: When it comes to safety training, no matter the industry, there are always questions regarding requirements f117 certifications. I denotes impact qstm followed by the impact resistance rating 75 or 50 in foot-pounds.
In higher voltages or higher risks 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. There are two basic names for shoes that have some protection from electrical shock: First, choose the protection level or specific standard you need: The most important thing to be aware of is that ASTM F is a standard designed primarily for impact and compression protection.
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. 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.

We put together this page with critical information to help answer your key questions about OSHA recordkeeping. This specification covers acceptance testing of dielectric overfoot and overshoe footwear designed to provide additional isolation or insulation of workers if ast, accidental contact with energized electrical conductors, apparatus, or circuits.
Some dielectric shoes cannot pass the compression portion of that standard because many are designed as overshoes and don’t aastm a steel toe, but the overshoes can be worn with compression-resistant shoes if needed. 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.
ASTM Dielectric Footwear
The ASTM F standard covers minimum requirements for the design, performance, testing, and classification of protective footwear. 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.
Only dielectric footwear is listed in 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 in the sole or heel, or workers touch conductive, grounded items.
The last line is used only when more than three sections apply. Only one boot and overshoe currently meets the F specification. Dielectric DI Shoes ” Nonconductive footwear must f1117 be used in explosive or hazardous locations.
ASTM F1117 Dielectric
The last two lines are used to identify footwear made to offer protection from other specific types of hazards referenced in the standard. ASTM F Reapproved is the specification for dielectric footwear and is a quite stringent standard. If f11117 are for acid protection, then they would need to meet an applicable part of F This abstract is a brief summary of the referenced standard. Footwear, unlike the rubber gloves used for primary protection in utilities, has nothing to protect it from the effects of walking and from the effects of ozone and UV light.
OSHA states, “Electrical hazard, safety-toe shoes are nonconductive and will prevent the wearers’ feet from completing an electrical circuit to the ground.
This is especially true for climbing poles, ladders, and aatm. Few guidelines exist on when and where to use the shoes in either standard.
ASTM F refers to the boots and overshoes as “supplementary protection” because the shoes have no “in-use” standard.
