Which type of harness is commonly used for high load capacity?

The correct choice refers to class two harnesses, which are designed to support a high load capacity, making them suitable for various applications, including rescue operations and industrial work. Class two harnesses generally include features that enhance safety and load distribution, such as additional padding and connection points. These harnesses are specifically engineered to handle the stresses associated with significant weight loads, ensuring that the user remains safe and secure while performing tasks that require high strength support.

In contrast, class one harnesses typically provide less support and are often used in situations with lower weight requirements or for fall protection where load capacity is not as critical. Class three harnesses focus on fall arrest systems and are not primarily classified by their load capacity but rather on their effectiveness in preventing falls. Additionally, stating that there is no specific class for load capacity neglects to recognize the classifications established by harness design and purpose, which clearly define their capabilities in load handling.
