Which statement about rubber footwear is correct?

Rubber footwear indeed has limited insulating properties, and while it can provide some degree of insulation, it is not considered dependable as a robust insulator against electrical hazards. The effectiveness of rubber as an insulator can be compromised by various factors such as moisture, wear, and the specific composition of the rubber used. Thus, one cannot always rely on rubber footwear for complete electrical safety in environments where there is a significant risk of electrical shock or high-voltage contact.

In contrast to rubber's ability to insulate to some extent, understanding the limitations and conditions under which it may fail is critical for safety considerations, especially for those working in high-risk environments like firefighting or electrical maintenance. This is why emphasizing that rubber footwear is not a dependable insulator aligns with safety awareness practices.
