What is the most important reason rigging hardware should NOT be modified?

The most important reason rigging hardware should not be modified is that it could negatively affect its capacity. Rigging hardware is designed and tested to specific standards and specifications that ensure its strength and reliability under load. Modifying this equipment, whether through welding, cutting, or altering its configuration, can compromise its structural integrity and lead to a significant reduction in its load capacity. This can create dangerous situations, as the hardware may not be able to withstand the forces it was originally intended for, potentially resulting in failures or accidents during lifting operations.

While there are other factors, such as responsibilities related to the gear, the need for re-testing, and potential costs, they do not override the fundamental safety concerns posed by altered hardware capabilities. The integrity and safety of lifting operations should always take precedence, and ensuring that rigging hardware remains unmodified is crucial for maintaining operational safety and compliance with industry standards.
