Fall arrest harnesses are an important safety equipment used in industries to prevent falls from heights. They are designed to distribute the force of impact during a fall over a larger area of the body, reducing the risk of injury. There are various types of fall arrest harnesses available, including full-body harnesses, waist harnesses, and chest harnesses. Full-body harnesses provide the most protection as they cover the entire body and distribute the force of impact across the chest, thighs, and shoulders. Waist and chest harnesses are used in situations where a full-body harness is not required. They are lighter and more comfortable to wear but provide less protection.
