What is the maximum height a panel can be shimmed or packed from its final resting surface?

The correct answer is based on industry standards and regulations regarding rigging practices, specifically the maximum height to which a panel may be shimmed or packed. In this context, a maximum height of 40mm is permissible to ensure stability, safety, and structural integrity during rigging operations. Shimming or packing beyond this height can lead to potential hazards such as instability or a failure to support the intended loads, which could result in accidents or equipment damage.

This limitation is established to maintain a balance between necessary adjustments for leveling and ensuring that the panel remains securely in place under operational conditions. By adhering to this maximum height, riggers can ensure a safer working environment while also complying with regulatory guidelines that govern safe rigging practices.
