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 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 f117 apparel.

I denotes impact resistance followed by the impact resistance rating 75 or 50 in foot-pounds.

They designate conductive Cd properties, electrical insulation properties EHstatic electricity dissipative SDpuncture resistance PRchainsaw cut resistance CSand dielectric insulation DIif applicable.

All manufacturers and users recommend regular visual inspections and replacement when any sign of excessive wear exists. The ASTM F standard covers minimum requirements for the design, performance, testing, and classification of protective footwear. 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.

Using Qstm and Electrical Hazard Shoes Minute holes in the soles of the f117 are the biggest area of atsm in the protection scenarios. By Hugh Hoagland Apr 01, There are two basic names for shoes that have some protection from electrical shock: The makers and users of dielectric shoes point out this fact.

ASTM F Reapproved is the specification for dielectric footwear and is a quite stringent standard. In higher voltages or higher risks Problems to Consider Most testing applies only to the sole of the footwear, which usually begins degrading quickly.

ASTM Dielectric Footwear

Dielectric DI Shoes ” 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. Mt means this shoe has metatarsal protection and rating 75 or 50 foot-pounds. C denotes compression resistance and the compression resistance rating 75 or 50, which correlate to 2, pounds and 1, pounds of compression, respectively.


Rubbers, designed to be worn over existing footwear and to cover only the foot of the worker; Boots, designed aastm 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.

When it comes to OSHA recordkeeping there are always questions regarding the requirements and in and outs. Also, look closely at the heel and sole design. 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. Second, choose the standard: IndustrySafe Safety Management Software helps organizations to improve safety by providing a f117 toolset of software modules to help businesses identify trouble spots; reduce claims, lost days, OSHA fines; and more.

ASTM Dielectric Footwear

Some dielectric shoes cannot pass the compression portion of that standard aastm many are designed as overshoes and don’t have a steel toe, but the overshoes can be worn with compression-resistant shoes if needed. An example of ASTM style markings for protective footwear is: Minute holes in the soles of the footwear are the biggest area of concern in the protection scenarios.

The higher the overshoe, the less likely it is that water, grass, or other energized materials contact the worker. Nonconductive footwear must not be used in explosive or hazardous locations. Fit and the ease of donning and doffing the footwear warrant consideration, especially on overshoes.

The outsole can provide a secondary electrical aastm resistance protection to the wearer against the hazards from an incidental contact with energized electrical circuits or parts.

OSHA states, “Electrical hazard, safety-toe shoes are nonconductive and will prevent the wearers’ feet from completing asrm electrical circuit to the ground.

ASTM F1117 Dielectric

Styles of overshoe footwear covered under this specification shall be designated as: 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. One shoe of each pair must be clearly and legibly marked stitched in, stamped on, pressure sensitive label, etc.


To purchase ASTM standards, see http: 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. A deep heel is needed to climb safely, while the normal aztm heel works well for walking. The last two lines are used to identify footwear made to offer protection from other specific types of hazards referenced in the standard. We put together this page with critical information to help answer your key questions about OSHA recordkeeping. Where insulated footwear is used as protection against step and touch potential, dielectric overshoes shall be required.

These shoes can g1117 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. IndustrySafe is here to help. The last line is used only when more than three sections apply. 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.

It is better in the sense that it does make use mandatory in a few cases but is still unclear about ast, role, if any, for EH shoes.

ASTM specification must be marked with the specific portion of the standard with which it complies. Third, look into the unique hazards of the work environment.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. High-risk tasks, environments, and medium and high voltages require more and more stable protection.

The CSA standard is also a “wet sole test. This is not usually acceptable for wet service or higher voltages.
