Which organization has established guidelines related to bonding metallic bodies for lightning protection?

The establishment of guidelines related to bonding metallic bodies for lightning protection is attributed to Underwriters Laboratories (UL). UL is a well-known organization that focuses on safety-related certification, testing, and standards development. Their guidelines are crucial in ensuring that structures have proper lightning protection systems, which include the bonding of metallic elements to create a unified conductive path. This prevents potentially dangerous differences in electrical potential that could occur during a lightning strike, thereby safeguarding both equipment and personnel.

While other organizations play significant roles in safety and standards – such as IEEE in electrical engineering and NIST in technology and measurement standards – it is UL that specifically addresses the requirements for effective bonding in the context of lightning protection. OSHA primarily deals with workplace safety and health standards, rather than specific guidelines for lightning protection systems.
