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 EHf11117 electricity dissipative SDpuncture resistance PRchainsaw atm resistance F111and dielectric insulation DIif applicable. The CSA standard is also a “wet sole test. The last line is used only when more than three sections apply. To purchase ASTM standards, see http: The most important thing to be aware of is that ASTM F is a standard designed primarily for impact and compression protection.
In higher voltages or higher risks Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The higher the overshoe, the less likely it is that water, grass, or other energized materials contact the worker.
ASTM F refers to the boots and overshoes as “supplementary protection” because the shoes have no “in-use” standard.
ASTM F Dielectric Footwear
ASTM F Reapproved is the specification for dielectric footwear and is a quite stringent standard. I denotes impact asym followed by the impact resistance rating 75 or 50 in foot-pounds.
Few guidelines exist on when and where to use the shoes in either standard. Styles of overshoe footwear covered under this specification shall be designated as: The makers and users of dielectric shoes point out this fact.
The ASTM F standard covers minimum requirements for the design, performance, testing, and classification of protective footwear. 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. Also, look closely at the heel and sole design. First, choose the protection level or specific standard you need: All manufacturers and users zstm regular visual inspections and replacement when any sign of excessive wear exists.
Electrical Hazard EH footwear is manufactured with non-conductive, electrical shock-resistant soles and heels. IndustrySafe Safety Management Software helps organizations to improve safety by providing a comprehensive toolset of software modules to help businesses identify trouble spots; reduce astk, lost days, OSHA fines; and more.
He has trained over 50, line-workers, managers, and electricians at large electric f117 and electric utilities and is a featured speaker at safety conferences.
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. Dielectric DI Shoes ” High-risk tasks, environments, and medium and high voltages require more and more stable protection. Dielectric or Electrical Hazard levels. When it comes to safety training, no matter the industry, there are always questions regarding requirements and certifications.
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 f1117 and UV light.
Insulated soles f11177 not be used as primary electrical protection.
ASTM Dielectric Footwear
We put together this page with critical information to help answer your key aastm about OSHA recordkeeping. This is not usually acceptable for wet service or higher voltages. IndustrySafe is here to help.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, satm or up to date. C denotes compression resistance and the compression resistance rating 75 or 50, which correlate to 2, pounds and 1, pounds of compression, respectively.
M in this case means the footwear is designed for a Male F would be Female. An OSHA interpretation letter from March 17,basically does not “require” electrical trades to wear “safety toed shoes. An example of ASTM style markings for protective footwear is: 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. Third, look into the unique hazards of the work environment.
The last two lines are used to identify footwear made to offer protection from other specific types of hazards referenced in the standard. A deep heel is needed to climb safely, while the normal shallow heel works well for walking. Steel toes have never been shown to conduct electricity as long as the toe is still covered with the shoe material. Second, choose the standard: 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.
Where insulated footwear is used as protection against step and touch potential, dielectric overshoes shall be required. 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.
This paper offers some assistance on which standards relate to which shoes.
