Electrical hazard (EH) footwear is designed to protect the wearer from electrical shocks or electrocution. EH-rated shoes are tested to 18,000 V and must be able to withstand this voltage for one minute without current passing through the body. The outsoles of EH shoes are electrically isolating, meaning they are non-conductive and significantly reduce the flow of electricity through the shoe and into the ground. EH-rated footwear is intended as a secondary source of protection and is not suitable for live electrical work.

What You'll Learn
EH-rated shoes are not a guarantee against electrocution
Electrical hazard (EH) shoes are designed to protect the wearer from electric shocks and electrocution. They are made from non-conductive materials that prevent the flow of electricity through them. However, it is important to note that EH-rated shoes do not guarantee complete protection from electrocution.
EH-rated shoes are tested to 18,000V and must provide electrical insulation for one minute. They are designed to be a secondary source of protection from electric shocks or electrocution. The outsoles of EH shoes are electrically isolating, which means they do not divert the electrical current to the ground. Instead, they impede the flow of electricity through the shoe, reducing the likelihood of electrocution for the wearer.
While EH-rated shoes offer a level of protection, they are not meant to be the primary safety precaution against electrical hazards. They are not suitable for live electrical work or for use in wet conditions. EH ratings focus on the shoe's sole and heel and are recommended for dry use only. In some electric situations, EH-rated shoes are not recommended.
It is also important to distinguish EH-rated shoes from other types of safety footwear, such as dielectric shoes, static dissipation footwear, and electrically conductive shoes. Dielectric boots are tested to high voltages and can be used in wet conditions, while EH-rated shoes are not. Static dissipation and conductive footwear are designed to conduct electricity through the shoe to eliminate the risk of static shock, which is important in environments where explosions or fires are more likely.
In summary, while EH-rated shoes provide a level of protection against electric shocks and electrocution, they are not a guarantee against electrocution. They are meant to be used in conjunction with other safety measures and may not be suitable for all electrical situations. It is important for workers to understand the limitations of EH-rated shoes and to follow all recommended safety precautions in their respective industries.

EH-rated shoes are not suitable for live electrical work
Electrical hazard (EH) safety boots are designed to protect the wearer from certain types of electric shocks or electrocution. The boots are made from non-conductive materials to prevent electrical charges from passing through the body, as the wearer is isolated from the ground. EH-rated boots are tested to 18,000 volts and must provide electrical insulation for one minute.
However, it is important to note that EH-rated shoes are not meant to be the primary safety precaution for electricity. They are intended as a secondary source of protection and are not suitable for carrying out live electrical work. While EH footwear directly protects the person, anti-static and electrostatic dissipative (ESD) footwear is designed to protect the electrical equipment the person is using.
ESD footwear has a very low electrical resistance in order to prevent a strong, uncontrolled electrostatic charge. It conducts static electricity through the insole, linings, cement, outsole, and into the ground, helping to regulate the buildup of electrical charge on a person's body. Anti-static footwear functions similarly, preventing a build-up of static electrical charges in the human body by sending these charges to the ground.
Dielectric shoes are also different from EH-rated shoes. Dielectric boots or overshoes are tested to high voltages and are capable of being used in wet conditions, while EH ratings focus on the shoe's sole and heel and are recommended for dry use only.

EH-rated shoes are not the same as dielectric shoes
Electrical hazard (EH)-rated shoes are designed to protect the wearer from electric shock and electrocution. They are a secondary source of protection when an outsole accidentally comes into contact with a live electrical circuit. The outsoles of EH-rated shoes are electrically isolating, meaning they significantly impede the flow of electricity through the shoe and into the ground. EH-rated shoes are tested to 18,000 volts and must provide electrical insulation for one minute. They are recommended for dry use only.
Dielectric shoes, on the other hand, are tested to high voltages and are capable of being used in wet conditions. While EH-rated shoes focus on the sole and heel, dielectric shoes are designed to provide protection for the entire foot. Dielectric shoes are typically used in industries where workers are exposed to high voltages and wet conditions, such as electrical work or utility work.
It is important to note that EH-rated shoes are not meant to be the primary safety precaution for electricity. They are designed to provide a secondary level of protection in addition to other safety measures. EH-rated shoes are recommended for workers who are around live wires and possible electricity, such as electricians, linesmen, industrial engineers, maintenance workers, and construction workers.
While both EH-rated shoes and dielectric shoes offer protection from electrical hazards, they have different purposes and are designed for specific types of work environments. EH-rated shoes are ideal for dry conditions and provide protection from electric shock, while dielectric shoes are designed for wet conditions and offer protection from high voltages. Therefore, it is crucial to select the appropriate type of footwear based on the specific hazards and requirements of the work environment.
Additionally, it is worth mentioning that neither EH-rated shoes nor dielectric shoes provide protection from static electricity. For protection from static electricity, workers may require static-dissipative (SD) or Electro Static Dissipative (ESD) footwear, which is designed to reduce the buildup of static electricity. ESD footwear is commonly used in electronics, aerospace, and sensitive manufacturing applications.

EH-rated shoes are not the same as static dissipation footwear
Electrical hazard (EH) shoes are designed to protect the wearer from electric shocks or electrocution. They are rated to protect against up to 600 volts in a dry setting and are tested to 18,000V. EH-rated shoes are not meant to be the primary safety precaution for electricity and are recommended for dry use only. They are not suitable for carrying out live electrical work.
Static Dissipating (SD) shoes, on the other hand, are designed to minimize the amount of static electricity build-up on the wearer's body. They are used in less hazardous environments, such as around printed circuit boards, where static sparks are a nuisance for workers. SD shoes have a higher resistance than conductive shoes, causing them to dissipate static electricity at a slower rate. They are designed to conduct electricity through the shoe to eliminate the risk of static shock.
ESD (Electro Static Dissipative) safety boots have an electrical resistance between 0.1 and 100 MΩ. They are designed to prevent a strong, uncontrolled electrostatic charge. They are crucial when working in environments where there is a risk of shocks from static charges, which can cause damage to electrical equipment.
While EH-rated shoes protect the wearer directly, static dissipation footwear is designed to ultimately protect the electrical equipment the person is using. EH-rated shoes are fully insulating, whereas static dissipation footwear is designed to conduct electricity through the shoe. Therefore, they serve different purposes and offer different levels of protection. It is important to note that employers are responsible for determining whether their employees require anti-static or ESD footwear based on the specific hazards and equipment in the work setting.

EH-rated shoes are not the same as electrically conductive shoes
Electrical hazard (EH) shoes are designed to protect the wearer from electrical shocks and electrocution. They are rated by the American Society for Testing and Materials (ASTM) and are tested to withstand 18,000 volts for one minute with a maximum current flow of 1.0 milliamperes. EH shoes are made with non-conductive materials and are fully insulating, preventing the flow of electricity through them. This is different from electrically conductive shoes, which are designed to conduct electricity through the shoe to eliminate the risk of static shock.
Conductive shoes have a low resistance range, typically between 0 and 500,000 Ohms, which allows for the easy flow of static electricity from the wearer through the shoes to the ground. This type of footwear is crucial in explosive and highly flammable environments, where sparks can be catastrophic. By conducting static electricity, conductive shoes eliminate electrostatic discharges and sparks, protecting the wearer from explosions.
On the other hand, EH-rated shoes are designed to impede the flow of electricity and provide a secondary source of protection from electrical shocks. They are not meant to be the primary safety precaution for electricity and are not suitable for live electrical work. Instead, they are recommended for dry use only and should be used in conjunction with other safety measures to protect against electrocution.
It is important to note that EH-rated shoes are not the same as dielectric shoes, which are tested to high voltages and can be used in wet conditions. EH-rated shoes focus on the sole and heel and are not intended for use in wet environments. Additionally, while EH-rated shoes protect against electrical hazards, they do not necessarily provide protection against slips and falls, which is another important consideration in workplace safety.
In summary, EH-rated shoes are designed to protect the wearer from electrical shocks and electrocution by impeding the flow of electricity. They are not the same as electrically conductive shoes, which are designed to conduct electricity to eliminate static shocks and protect against explosions in hazardous environments. It is crucial to choose the appropriate footwear based on the specific hazards and equipment in the work setting to ensure adequate protection.
