What is the main purpose of the "three point contact" rule?

The main purpose of the "three point contact" rule is to ensure safe entry and exit from machinery. This rule involves maintaining three points of contact with the equipment at all times, such as two hands and one foot or two feet and one hand. This technique significantly increases stability and balance, reducing the risk of falls and injuries while getting in and out of machinery. It is a critical safety practice in operating heavy equipment because falls are one of the most common hazards in the workplace, especially in construction and machinery operation settings.

While the other options touch on relevant concepts, they do not capture the fundamental intent of the three point contact rule, which is primarily focused on safety rather than efficiency, visibility, or contact reduction.
