Following a recent heavy stormy rain that destroyed some critical ICT equipment in two UNICEF offices, the need to do a comprehensive review of the existing thunder arrestor and earthing system in all field offices to ascertain their functionality and ability to protect the infrastructure, and to propose changes where necessary to ensure the resistance to the ground plane is within acceptable ohmic (less than 10 ohms) value that guarantees protection of all installed equipment against occasional electrical surge and lightning strikes has become necessary.
