scope:

This Recommendation1 aims to help with compliance of telecommunication network personnel working in vicinity of medium-voltage (MV) and high-voltage (HV) power lines with safety limits for human exposure to electromagnetic fields (EMFs) at power frequencies (DC, 50 Hz and 60 Hz). Also, it aims to provide practical work rules as one of the means of safeguarding network personnel that may need to work in close proximity to the MV and HV power lines.

Where local or national laws, standards or guidelines on work safety or exposure limits to EMF exist and provide procedures that are at variance with this Recommendation, the pertinent local or national laws, standards or guidelines shall take precedence over the procedures provided in this Recommendation.

This Recommendation does not cover exposure to electromagnetic fields at frequencies other than DC, 50 Hz and 60 Hz. This Recommendation does not cover exposure to touch currents that arise as a result of coupling of electromagnetic fields generated by the power lines to other metallic objects, including telecommunication circuits.

[b-ITU-T K.52] aims to help with compliance of telecommunication installations and mobile handsets or other radiating devices used against the head with safety limits for human exposure to electromagnetic fields (EMFs).

[b-ITU-T Vol.VI] covers safety issues related to people coming in contact with telecommunication circuits exposed to the induction of AC electric power or AC electrified railway lines.

1 This Recommendation includes an electronic attachment containing the EMFACDC program.
