Where are cracks in insulated gloves most likely to occur?

• A. On the fingertips
• B. On the back of the hand
• C. Between the fingers and where the glove flexes a lot
• D. On the wrist

Answer: (C)

Cracks form where the glove bends and flexes most often. The areas between the fingers and at the joints undergo repeated stretching and folding during gripping and manipulation of tools, creating stress concentrations that initiate micro-tears. Over time these cracks can propagate, compromising the glove’s insulation.

The fingertips and the back of the hand bend less severely than the finger joints, and the wrist area experiences less repeated flexion, so cracks are less likely to start there. Surface wear can occur, but the primary failure points are the flex zones where stress accumulates with regular use.

That’s why inspection before use focuses on the gaps between the fingers and along the folds and knuckles, looking for any cracking, thinning, or signs of wear. If any crack is found, the glove should not be used, and appropriate dielectric testing or replacement follows safety standards.
