Which of the following factors is NOT advised when storing synthetic slings?

When it comes to storing synthetic slings, it is crucial to consider the effects of environmental factors on their longevity and performance. Storing synthetic slings in direct sunlight is not advised because UV exposure can degrade the materials over time. Sunlight can weaken the fibers, leading to a reduction in strength and potentially compromising safety during use.

Keeping synthetic slings dry is important to prevent mold and mildew, which can also weaken the material. Additionally, oil and other chemicals can damage the fibers of synthetic slings, so they should be kept away from these substances. Proper ventilation is also essential because it helps prevent moisture buildup and promotes airflow, which can further protect the slings from damage.

Therefore, avoiding direct sunlight during storage is critical to maintaining the integrity of synthetic slings and ensuring their safe use in rigging operations.
