What is a critical component that should be checked before installation of the LP system?

Ensuring that adhesive properties are suitable before the installation of a lightning protection (LP) system is crucial because the effectiveness and durability of the system can be significantly influenced by the materials that are used to bond various components together. Proper adhesives ensure that the lightning protection system stays securely attached to structures, which is essential for maintaining the integrity of the system over time. Adhesive strength can be affected by several factors including temperature, humidity, and the surfaces being bonded. If the adhesive used does not meet the required specifications or is incompatible with the materials, it could lead to a failure in the system, compromising its performance during a lightning event.

In contrast, while weather conditions and plan approvals are important considerations in the overall planning and execution of the LP system installation, they do not directly relate to the immediate structural integrity of the components once installed. Mechanical stability is certainly a key factor in the installation process, but looking specifically at the properties of the adhesives used provides a more immediate assurance of the system's performance and longevity.
