1. Lightning overview
2. Lightning behavior, and its effects on buildings and people
3. The lightning protection system for facilities and structures
A. Page-by-page review of NFPA-780-2008, Installation of Lightning Protection Systems. Emphasis is on:
- Air terminal designs
- Conductors/connectors/bonding
- Grounding
- Surge protection
- Stand-off calculations
- Testing
- 780 appendices
- Maintenance
- Inspection
B. Looking outside the NFPA-780 box
4. In-depth review of applicable military codes and standards, such as AFI 32-1065, PAM 385-64, NAVSEA OP5.
5. Review of National Electrical Code (NEC) sections 250/280/285
6. Hands-on grounding resistivity measuring
A. 3-point fall of potential ground resistance tester
B. Clamp-on ground resistance tester
7. Site assessment of existing LP systems
