Nylon web slings should not be used near which of the following?

Nylon web slings are highly versatile and widely used in lifting applications due to their strength and durability. However, they have specific limitations regarding their exposure to certain substances.

When it comes to acids, nylon is susceptible to degradation when exposed to them. Acids can weaken the fibers of the nylon, which compromises the sling's structural integrity and increases the risk of failure during lifting operations. The chemical reaction between the nylon and acid can lead to a reduction in the sling's load capacity, posing significant safety hazards.

In contrast, nylon web slings can withstand other conditions, such as being near heat sources within certain limitations, contact with water (as they can handle moisture well but may absorb it), and even oils, although prolonged exposure to certain oils can affect their performance. However, the priority in terms of safety is to avoid using nylon web slings in environments where they may come into contact with acids to ensure the reliability and safety of lifting operations.
