When must hard hats be worn on a construction site?

Hard hats must be worn at all times when exposed to overhead hazards due to the inherent risks associated with construction sites. The primary purpose of hard hats is to protect workers from head injuries that can occur from falling objects, bumps, or electrical hazards. On a construction site, workers can often be in the vicinity of tools, materials, or equipment that could potentially fall or strike their heads, making consistent use of hard hats essential for safety.

Wearing hard hats is a proactive approach to reduce the likelihood of serious injuries and is an important aspect of complying with OSHA regulations for maintaining a safe work environment. While specific tasks may require additional safety measures, the general requirement to wear hard hats applies consistently to protect all workers whenever there is a risk posed by overhead hazards.
