Which additional layer is mentioned for the back of the hand?

• A. Leather reinforcement
• B. Nomex on the back of the hand
• C. Carbon fiber pad
• D. Silicone coating

Answer: (B)

Adding Nomex on the back of the hand provides a flame- and heat-resistant layer for the dorsum of the hand, which often faces radiant heat and brief flame exposure during tool work and reach-and-grab motions. Nomex is an aramid fabric known for maintaining integrity at high temperatures, so it protects without adding bulk or sacrificing dexterity. Leather reinforcement adds durability and abrasion resistance but not the same inherent flame resistance. A carbon fiber pad is more about impact/rigidity than heat protection. A silicone coating improves grip and some surface protection, but is not described as the additional back-of-hand layer for heat resistance.
