About this file
This document is a letter from A-1 Lightning Protection dated July 28, 2022, describing the existing lightning protection systems at the John J Pershing VA Medical Center in Poplar Bluff, Missouri. The letter details lightning protection specifications for two key areas: the 7th floor roof and the Urgent Care Section. For the 7th floor roof, the protection includes a Class II cable around the parapet, air terminals secured to the wall, four grounding routes, bonded masts/antennas, and grounded metal inductance bodies. The Urgent Care Section features Class I Aluminum cable, conductors, air terminals, properly bonded stacks and soil pipes, and appropriate grounds. The letter notes that while the handrails have been grounded, they do not fully meet the UL96 lightning protection requirements.

Re: John J Pershing VA Medical Center July 28, 2022
Poplar Bluff, MO
The following is a description of the existing lightning protection on the entire structure as of this letter date:
The 7th floor roof (highest roof) has:
- Class II cable run around the base of the parapet with an adequate number of air terminals secured to the wall and extending above the top of the wall.
- Four grounds which run down the side of the walls to the 7th floor, continue through the 6th floor parapet and down to earth.
- All masts/antennas taller than air terminals are bonded to grounds per
UL96(approximately 10 total).
- All grounded metal bodies of inductance are bonded per UL96.
The Urgent Care Section has the following:
- Class I Aluminum cable, conductors and air terminals.
- All stacks and soil pipes have been properly bonded/protected per UL96.
- Proper number of air terminals and grounds per UL96.
The handrails around the entire structure have been grounded but do not meet the lightning protection requirements for UL96.
