What could contribute to the failure of safety nets?

The failure of safety nets can be significantly influenced by chemical damage. Safety nets are typically made from materials that can be affected by harsh chemicals, including solvents, acids, and other corrosive substances. When these chemicals interact with the net material, they can weaken its structure, reducing its overall strength and durability. Consequently, this weakening can lead to a higher likelihood of failure when the net is subjected to loads or conditions it was designed to withstand.

In contrast, the other options do not directly relate to the failure of safety nets in a significant way. Using safety nets in controlled environments often minimizes risks and ensures that they are utilized under ideal conditions, while proper installation techniques enhance their effectiveness and durability. Regular maintenance is vital to ensure that safety nets remain in good condition, helping to identify and rectify any wear or damage before it leads to failure.
