What are common failure modes for insulated gloves?

• A. Tears near the wrist
• B. Fading color
• C. Water absorption
• D. Cracks between the fingers and where the glove flexes a lot

Answer: (D)

When insulated gloves are used, failure often starts where the material is bent the most. The areas between the fingers and the places where the glove flexes with hand movement endure the highest repetitive stress. Over time this stress creates microcracks and then larger cracks in the flexible zones. Once cracks form, the dielectric barrier is compromised, moisture or contaminants can enter, and the glove’s insulating performance drops, increasing the risk of electrical shock. That makes cracks in the finger joints and other high-flex areas the most common and critical failure mode.

Tears near the wrist can happen, and cosmetic changes like color fading can occur, but they don’t indicate insulation integrity as reliably. Water absorption isn’t as direct a failure marker as structural cracks in the most stressed areas.
