Where should fiberglass ladders be stored to ensure their longevity?

Storing fiberglass ladders out of direct sunlight is crucial for their longevity because the materials used in their construction can degrade when exposed to UV rays and extreme heat. Prolonged sunlight exposure can weaken the fiberglass, leading to potential structural failure, compromising safety during use. By keeping the ladders away from direct sunlight, you help maintain their integrity and durability over time.

The other options generally create conditions that can be harmful to fiberglass. Damp environments can lead to mold or mildew, while heated garages may contribute to fluctuations in temperature that could impact the ladder's materials. Storing ladders near sources of humidity can also increase the risk of damage or degradation of the ladder's structure. Therefore, protection from sunlight is the best practice for ensuring the longevity of fiberglass ladders.
