What is the minimum requirement for a double deviation setup?

The minimum requirement for a double deviation setup is to ensure that the system provides adequate redundancy and safety when accessing work areas from height. In this context, having two anchors rated at 15kN each allows for sufficient strength to support two independent lines, which is crucial for a double deviation configuration.

Using two ropes or slings ensures that if one system fails, the second still remains in place to support the technician. This redundancy is an essential safety principle in rope access, where potential hazards must be managed appropriately. Additionally, two carabiners are used to connect each rope to the anchors, providing secure attachment points and allowing for smooth transitions during ascent or descent. Each component of this setup is designed to maintain the integrity and safety of the rope access system, aligning with best practices in the industry.

This understanding of using appropriately rated anchors, the necessity of redundancy with two ropes, and the correct amount of carabiners is fundamental for technicians working at height. Other setups listed may not meet these critical safety requirements.
