What type of sling should not be used as chokers?

The correct choice is that TT - Triangle to Triangle slings should not be used as chokers due to their design and intended application. Choker hitches typically require the sling to create a tight grip around the load, which can cause excessive wear and potential damage if the sling is not designed for that type of configuration.

Triangle to Triangle slings are often designed for specific lifting applications and may not provide the same level of load security or protection against stress and abrasion that other sling types can offer when used in a choker configuration. The geometry and stability of the load may be compromised when employing this type of sling in such a manner, increasing the risks of slippage or even failure during the lifting process.

In contrast, web slings, round slings, and wire rope slings are generally built with flexibility, strength, and the ability to conform around loads when configured as chokers, which makes them suitable for this type of hitch. Each of these sling types can maintain a secure grip while accommodating the various shapes of loads, reducing the risk of accidents.
