Why should hard hats not be stored in direct sunlight?

Storing hard hats in direct sunlight is critical to maintaining their integrity because UV rays can break down the materials from which the helmet is made. Many hard hats are constructed from polymers that can degrade when exposed to prolonged sunlight, leading to a reduction in their ability to protect the wearer effectively. Over time, exposure to these rays can weaken the hard hat's structure, making it less effective in protecting against impacts or falling objects. Ensuring that hard hats are kept out of direct sunlight helps prolong their lifespan and ensures they meet safety standards when needed.
