Hard hats are also known as safety helmets, an item of PPE (personal protective equipment). Hard hats protect your head from falling objects and impact from other objects also protecting from electrical shock. Hard hats are worn within roofing and construction, also in forestry and offshore industries. They can be worn any environment by anyone. Hard hats are a legal safety requirement for you to wear on construction sites worldwide. You can find out more in our hard hats guide.
How are they constructed?
Hard hats are made from strong plastic such as HDPE (high-density polyethylene). There are suspension bands within the helmet that spread impact force over the top of the head, reducing injury. Hard hats can be supplied with a chin strap or ratchet adjustment keeping the hat firmly in place. Some models are vented to keep your head cool whilst working, for example, the Petzl Helmet range.
