When should you wear a hard hat on a construction site?

Wearing a hard hat on a construction site is crucial whenever there is a risk of head injury from falling or flying objects. The primary purpose of a hard hat is to protect the head from potential impacts that could occur due to various hazards present on construction sites, such as tools or materials that could fall, or debris that might be dislodged. This safety measure is not limited to specific types of work or conditions; rather, it is a general precaution that should be taken in environments where such risks are present.

In addition, hard hats also provide protection from electrical hazards, although wearing one is not restricted to electrical work alone. It is a standard practice in the construction industry to wear hard hats in any situation where there could be a potential for head injury. As such, relying solely on specific conditions, like working at heights or operating heavy machinery, does not encompass the broader range of scenarios where head protection is necessary.
