Using blocks and pads before the installation of slings is vital for ensuring their protection. Slings are used to lift and secure loads, and their longevity and performance can be significantly affected by the surfaces they come into contact with during use. By employing blocks and pads, you create a buffer that helps prevent damage from sharp edges or rough surfaces that could wear down the sling material. This protective measure not only preserves the integrity of the slings but also enhances safety during lifting operations by reducing the risk of failure due to abrasion or cutting.

In contrast, while running a safety check is important for overall safety protocols, it does not specifically address the protection of slings during installation. Similarly, cutting excess length may not be applicable as it could compromise the sling’s capacity to support loads effectively. Applying lubricant is also inappropriate, as it may interfere with the material integrity or create slippage, posing additional risks. Therefore, using blocks and pads stands out as the most effective and practical measure for protecting slings before installation.
