Which of the following would NOT be a characteristic of Class 4 rubber gloves?

Class 4 rubber gloves are specifically designed for electrical insulation, particularly in high-voltage applications, which gives them the critical role of protecting users from electrical hazards. The gloves are typically manufactured from rubber and are often color-coded, with Class 4 gloves commonly being orange.

The characteristic that sets them apart is their ability to withstand high voltages and provide essential protection against electrical shocks. Leather, on the other hand, is not a material used for manufacturing Class 4 rubber gloves because it does not offer the same level of electrical insulation. Instead, rubber, being an insulator, is the preferred choice for ensuring the safety of the user in environments where electrical exposure is a concern. Thus, the fact that Class 4 rubber gloves are made from leather is not accurate, making it the correct answer in this context.
