a) Lightning protection systems for
explosive structural facilities should be
visually inspected every six months. The
installation should be metrologically tested
once per year. To obtain ndings about
the seasonal uctuations, it is permissible
to take measurements at 14 to 15-month
intervals so as to determine the earth wire
circuit resistance at different times of the
year.
b) “Critical situations” could refer to
structural facilities containing systems
that are sensitive to interference or to
ofce buildings, commercial properties or
places where a large number of people
may reside.
