Nylon slings are not to be used in temperatures over what?

• A. 250 degrees
• B. 300 degrees
• C. 150 degrees
• D. 194 degrees

Answer: (D)

Nylon slings have a limited temperature tolerance because nylon softens and loses strength when heated. The commonly accepted maximum temperature for safe use is about 194°F (90°C). Exceeding this limit reduces the sling’s load capacity and increases the risk of failure, even if the load itself seems manageable. So nylon slings should not be used above roughly 194°F. The other options either exceed that limit or are below it, but 194°F is the practical cut-off you must follow.
