A labor safety helmet, commonly referred to as a hard hat, is a type of protective headgear worn by workers in various industries to reduce the risk of head injuries caused by falling objects, impact from low-hanging structures, and electrical hazards.

These helmets are typically made from high-density polyethylene (HDPE) or acrylonitrile butadiene styrene (ABS) plastic, which provides durability and impact resistance while remaining lightweight for comfortable wear. The outer shell of the helmet is designed to absorb and distribute the force of impacts, helping to minimize the severity of head injuries.

Labor safety helmets often feature an adjustable suspension system inside the helmet shell, allowing the wearer to customize the fit for comfort and stability. Some helmets may also include additional features such as chin straps for secure retention, ventilation slots for airflow, and accessory slots for attaching hearing protection, face shields, or other safety accessories.

These helmets are commonly worn by workers in industries such as construction, manufacturing, mining, forestry, and utilities, where there is a risk of head injuries from falling objects or overhead hazards. They are an essential piece of personal protective equipment (PPE) mandated by occupational safety regulations and standards to ensure the safety and well-being of workers on job sites.
