2.7.1.6.7 Rope access technicians should be aware that climatic conditions can affect the performance of some equipment or combinations of equipment. For example, humidity can alter (reduce) the friction provided between the descending device and the anchor line, and thus the performance is altered. This also applies to some ascending devices. Cold conditions can also affect performance, e.g. icy anchor lines can affect the grip of anchor line devices on them. Wet anchor lines can exhibit greater elongation characteristics than dry ones and wet polyamide anchor lines tend to be less resistant to abrasion. In very cold conditions, the strength of some metals is affected. Rope access technicians should check the information provided by the manufacturer to determine the acceptable operating conditions.
