Posted 26/08/2011 - A number of shareholders had their lightning conductors tested
recently. One of the shareholders raised some questions to the service provider, and these are
provided below together with the resposes received.
1. Is it required by Law or stated in the NHBR-or-SABS regulations that a conductor for
a thatched roof residence has to be inspected
annually?
1. It is recommended by the SABS to have lightning conductors checked
annually.
2. If not required by Law, the NHBR or SABS, is it required by the Short Term
Insurance?
1.
The final say rests with your insurer as to how often the lightning conductor needs
to be checked, they should however take heed of the SANS 10313 Code of Practice for the
Protection of Structures Against Lightning.
3. Which components do you inspect/service on the Lightning Conductor?
1. The ohmic resistance is measured and should be under 50 Ohm in order to be SABS
compliant. A physical examination of the lightning conductor is also carried out including angle
of protection and safe distance from thatch overhang.
4. Does this inspections/services only have to be performed on Lightning
Conductors that is situated on the mountain?
1. All lightning conductors, regardless of where they are situated, should be
tested.
5. Do you issue a COC after inspection that can be produced to the Board of
directors?
1.
Yes, a COC is issued if all is in order and the system is SABS
compliant.
6. Is all the information and regulations as well as inspection intervals listed on
your web-site?
1.
The information pertaining to SABS regulations are downloadable off the SABS website
at a fee (not sure how much but know that its not cheap).
7. Do the residents of Welgefonden Game Ranch and other Ranches and farmers in the
vicinity also have their Lightning Conductors tested/inspected annually?
1. Yes, I frequently test lightning conductors at some of the lodges at
Welgevonden and other reserves as well.
