What should be avoided as anchor points on buildings?

Anchoring to chimneys and drain lines should be avoided because these structures are not designed to bear the heavy loads that can be encountered during a rescue operation. Chimneys, for instance, may be constructed from materials that can crumble or fail under stress, and drain lines do not provide any structural integrity. Using such points can create a significant risk of anchor failure, which could jeopardize both the safety of rescuers and the individuals they are assisting.

Furthermore, these anchor points might not have the necessary stability or durability over time, particularly under dynamic loads that occur during rope rescue. Choosing reliable and robust anchor points is critical in ensuring both safety and effectiveness during rescue operations.
