Surge Protection. A lightning protection system for structures housing sensitive materials shall be designed for
surge protection as well as lightning strokes interception. Lightning flashes may produce electromagnetic pulses
that may couple internal and external power.
Inspecting and Testing
Lightning protection systems must be visually inspected every seven months. They must be tested for continuity
and grounding every 14 months.
Test Instruments
Only test instruments designed specifically for earth and ground system testing should be used. The instrument
must be able to measure 10 ohms 10 percent for bonding testing.
OPERATIONAL SAFETY
Personnel charged with responsibilities for ammunition must be motivated and reminded continuously that their
safety, as well as that of others, depends upon the care they use in performing their assigned duties. They must
ensure that:
The minimum number of personnel are exposed for the minimum amount of time to the smallest quantities of
explosives consistent with safety and efficiency.
Only required personnel work on an operation.
Safety precautions are observed and enforced rigorously.
