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,

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. 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.

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. To purchase ASTM standards, see http: 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.

Where insulated footwear is used as protection against step and touch potential, dielectric overshoes shall be required. Mt means this shoe has metatarsal protection and rating 75 or 50 foot-pounds. An example of ASTM style markings for protective footwear is: 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 and optional fourth line: When it comes to OSHA recordkeeping there are always questions regarding the requirements aastm in and outs. 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 r1117 additional precautions to reduce the risk of a worker becoming a path for hazardous electrical energy.

The higher the overshoe, the less likely it is that water, grass, or other energized materials contact the worker.

ASTM F1117 Dielectric

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. The most important thing to be aware of is that ASTM F is a standard designed primarily for impact and compression protection.


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. 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. There are two basic names for shoes that have some protection from electrical shock: Which Standard Do I Choose?

Link to Active This link will always route to the current Active version of the standard. One shoe of each pair must be clearly and legibly marked stitched in, stamped on, pressure sensitive label, etc. I denotes impact resistance followed by the impact resistance rating 75 or 50 in foot-pounds.

Second, choose the standard: Historical Version s – view previous versions of standard. They designate conductive Cd properties, electrical insulation properties EHstatic electricity sstm SDpuncture resistance PRchainsaw cut resistance CSand dielectric insulation DIif applicable. The last line is used only when more than three sections apply.

It has three procedures that differ according to the section of the footwear tested.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Few guidelines exist on 1f117 and where to use the shoes in either 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. Only one boot and overshoe currently meets the F specification.

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


An OSHA interpretation letter from March 17,basically does not “require” electrical trades to wear “safety toed wstm.

ASTM F – 14a Standard Test Method for Determining Dielectric Strength of Dielectric Footwear

Fit and the ease of f11117 and doffing the footwear warrant consideration, especially on overshoes. All manufacturers and users recommend regular visual inspections and replacement when any sign of excessive wear exists.

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. Using Dielectric and Electrical Hazard Shoes Minute holes in the soles of the footwear are the biggest area of concern in the protection scenarios. High-risk tasks, environments, and medium and high voltages require more and more stable protection.

C denotes compression resistance and the compression resistance rating 75 or 50, which correlate to 2, pounds and 1, pounds of compression, respectively. Also, look closely at the heel and sole design.

This paper offers some assistance on which standards relate to which shoes. Insulated soles shall not be used as primary electrical protection.

ASTM Dielectric Footwear

The CSA standard is also a “wet sole test. ASTM F Reapproved is the specification for dielectric footwear and is a quite stringent standard. IndustrySafe is here to help. IndustrySafe Safety Management Software helps organizations to adtm safety by providing a comprehensive toolset of software modules to help businesses identify trouble spots; reduce claims, lost days, OSHA fines; and more.

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. This is especially true for climbing poles, ladders, and stairs.

Dielectric or Electrical Hazard levels. Third, look into the unique hazards of the work environment.
