Electrically insulated gloves protect workers from electrical shock and arc flash hazards when working on or near electrical equipment. There are several different types of electrically insulated gloves, including:

1. Class 0 gloves: Class 0 gloves are designed for low-voltage (up to 1,000 volts) applications and offer minimal protection against electrical shock.
2. Class 1 gloves: Class 1 gloves are designed for medium-voltage (up to 7,500 volts) applications and offer moderate protection against electrical shock.
3. Class 2 gloves: Class 2 gloves are designed for high-voltage (up to 17,000 volts) applications and offer a high level of protection against electrical shock.
4. Class 3 gloves: Class 3 gloves are designed for use in extra-high-voltage (over 17,000 volts) applications and offer the highest level of protection against electrical shock.
5. Arc-rated gloves: Arc-rated gloves are designed to protect against arc flash hazards and are rated based on the level of protection they provide.

It is important to note that different types of electrically insulated gloves are suitable for different applications and voltage levels, and it is essential to select the appropriate type of glove based on the specific electrical hazards present in the work environment. It is also essential to properly maintain and test electrically insulated gloves to ensure they are in good condition and provide the necessary level of protection.
