Insulating gloves are one of the most critical pieces of personal protective equipment (PPE) for linemen, as they provide a barrier between the worker's hands and the electrical equipment they are handling. These gloves are designed to prevent electrical current from flowing through the worker's body and causing harm.
Insulating gloves are classified into different classes based on the level of voltage protection they provide. The class of gloves needed will depend on the voltage of the equipment being worked on. The four classes of insulating gloves for linemen are Class 00, Class 0, Class 1, and Class 2.
Class 00 gloves are designed to provide protection for workers handling low-voltage equipment up to 500 volts. These gloves are made of a natural rubber or a synthetic material and have a maximum use voltage of 500 volts AC or 750 volts DC.
Class 0 gloves provide protection for workers handling low-voltage equipment up to 1000 volts. These gloves are also made of natural rubber or a synthetic material and have a maximum use voltage of 1000 volts AC or 1500 volts DC.
Class 1 gloves provide protection for workers handling medium-voltage equipment up to 7500 volts. These gloves are made of natural rubber and have a maximum use voltage of 7500 volts AC or 11250 volts DC.
Class 2 gloves provide protection for workers handling high-voltage equipment up to 17,000 volts. These gloves are also made of natural rubber and have a maximum use voltage of 17,000 volts AC or 25,500 volts DC.
The materials used in insulating gloves for linemen are typically rubber or a synthetic material that offers similar electrical insulating properties. Natural rubber gloves are the most common and offer excellent electrical insulating properties. However, synthetic gloves made of materials such as neoprene or vinyl can be a good alternative for workers with latex allergies.
It's important to note that insulating gloves should be tested regularly to ensure they meet the requirements of the applicable standard. The gloves should be visually inspected before each use to ensure they are free from cuts, punctures, or any other damage that may compromise their integrity. The gloves should also be tested periodically using an appropriate test method to verify their electrical insulating properties.
In conclusion, insulating gloves are an essential piece of PPE for linemen working with high-voltage electrical equipment. The four classes of insulating gloves available offer different ranges of protective voltages, allowing workers to choose the appropriate glove for their specific task. Natural rubber is the most commonly used material for insulating gloves, but synthetic materials are also available for workers with latex allergies. Testing insulating gloves regularly is crucial to ensure their integrity and to prevent electrical accidents and injuries.
