ASTM F1117 PDF
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,

He has trained over 50, line-workers, managers, and electricians at large electric users and electric utilities and is a featured speaker at safety conferences. He is the senior managing partner and co-founder of e-Hazard, ff1117 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.
ASTM F1117 Dielectric
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. If they are for acid protection, then they would need to meet an applicable part of F Which Standard Do I Choose? 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.
Electrical Hazard 1f117 footwear is manufactured with non-conductive, electrical shock-resistant soles and heels.
ASTM specification must be marked with the specific portion of the standard with which it complies. This abstract is a brief summary of the referenced standard. Only dielectric footwear is listed in There are two basic names for shoes that have some protection from electrical shock: By Hugh Hoagland Apr 01, There are two basic names for shoes that have some protection from electrical shock: When it comes to OSHA recordkeeping there are always questions regarding the requirements and in and outs.

ASTM Dielectric Footwear
IndustrySafe is here to help. The ASTM F standard covers minimum requirements for the design, performance, testing, and classification of protective footwear.
Problems to Consider Most testing applies only to the sole of the footwear, which usually begins degrading quickly. This is especially true for climbing poles, ladders, and stairs.
Few guidelines exist on when and where to use the shoes in either standard. Third and optional fourth line: Second, choose the standard: Also, look closely at the heel and sole design.
ASTM F Dielectric Footwear
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.
C denotes compression resistance and the compression resistance rating 75 or 50, which correlate to 2, pounds and 1, pounds of compression, respectively. The most important thing to be aware of is that ASTM F is a standard designed primarily for impact and compression protection.
Using Dielectric and Electrical Hazard Shoes Minute holes in the soles of the footwear are the biggest area of concern in the protection scenarios.
An example of ASTM style markings for protective footwear is: The last two lines are used to identify footwear made to offer protection from other specific types of hazards referenced in the standard. OSHA states, “Electrical hazard, safety-toe shoes are nonconductive and will prevent the wearers’ feet from completing an electrical circuit to the ground.
The higher the overshoe, the less likely it is that water, grass, or other energized materials contact the worker. 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.
Insulated soles shall not be used as primary electrical protection. This paper offers some assistance on which standards relate to which shoes. 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.
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. Steel toes have never been shown to conduct electricity as long as the toe is still covered with the shoe material. An OSHA interpretation letter from March 17,basically does not “require” electrical trades to wear “safety toed shoes.
It has three procedures that differ according to the section of the footwear tested. Dielectric DI Shoes ” 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.
Only one boot and overshoe currently meets the F specification.
They designate conductive Cd properties, electrical insulation properties EHstatic electricity dissipative SDpuncture resistance PRchainsaw cut resistance CSand dielectric insulation DIif applicable.
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.
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. 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. The differences between the standards are not usually understood, even by electrical specialists. Styles of overshoe footwear covered under this specification shall be designated as: When it comes to safety training, no matter the industry, there are always questions regarding requirements and certifications.
In higher voltages or higher risks Mt means this shoe has metatarsal protection and rating 75 or 50 foot-pounds. 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.
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. 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.
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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Minute holes in the soles of the footwear are the biggest area of concern in the protection scenarios.
