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 designate conductive Cd properties, electrical insulation properties EHstatic asym dissipative SDpuncture resistance PRchainsaw cut resistance CSand dielectric insulation DIif applicable.
The last line is used only when more than three sections apply. 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.
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.
An example of ASTM style markings for protective footwear is: In higher voltages or higher risks High-risk tasks, environments, and medium and high voltages require more and more stable protection.
The CSA standard is also a “wet sole test. A deep heel is needed to climb safely, while the normal shallow astn works well for walking.
ASTM F – 03() Standard Specification for Dielectric Footwear
Only dielectric footwear is listed in 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. This paper offers some assistance on which standards relate to which shoes. M in this case means the footwear is designed for a Male F would be Female.
OSHA states, “Electrical hazard, f11177 shoes are nonconductive and will prevent the wearers’ feet from completing an electrical circuit to the ground. If they are for acid protection, then they would need to meet an applicable part of F Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
ASTM F1117 Dielectric
In-use standards normally require re-testing, so shoes should never be relied on as primary protection. Problems to Consider Most testing applies only to the f11117 of the footwear, which usually begins degrading quickly.
Third and optional fourth line: I denotes impact resistance followed by the impact resistance rating 75 or 50 in foot-pounds. By Hugh Hoagland Apr 01, There are two basic names for shoes that have some protection from electrical shock: All manufacturers and users recommend regular visual inspections and replacement when any sign of excessive wear exists.
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. 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.
When it comes to OSHA recordkeeping there are always questions regarding the requirements and in and outs.
Electrical Hazard EH footwear is manufactured with non-conductive, electrical shock-resistant soles and heels. Link to Active This link will always route to the current Active version of the standard.
Also, look closely at the heel and sole design.
ASTM Dielectric Footwear
The ASTM F standard covers minimum requirements for the design, performance, testing, and classification of protective footwear. When it comes to safety training, no matter the industry, there are always questions regarding requirements and certifications. Only one boot and overshoe currently meets the F specification. The makers and users of dielectric shoes point out this fact.
Which Standard Do I Choose? 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. The most important thing to be aware of is that ASTM F is a standard designed primarily for impact and compression protection. This is especially true for climbing poles, ladders, and stairs.

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. 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.
Nonconductive footwear must not be used in explosive or hazardous locations. 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. Third, look into the unique hazards of the work environment.
ASTM F Dielectric Footwear
Few guidelines exist on when atm where to use the shoes in either standard. Using Dielectric and Electrical Hazard Shoes Minute holes in the soles of the footwear are the biggest area of concern in the protection scenarios. Mt means this shoe has metatarsal protection and rating 75 or 50 foot-pounds.
Insulated soles shall not be used as primary electrical protection.
This is not usually acceptable for wet service or higher voltages. Styles of overshoe footwear covered under this specification shall be designated as: ASTM F refers to the boots and overshoes as “supplementary protection” because the shoes have no “in-use” standard.
