National Assessment Instruments - WA amendment - Clearance distances when working near or in the vicinity of overhead power lines

The National Assessment Instruments (NAIs) for the High Risk Work Licence (HRWL) classes listed below; include a question in relation to the minimum safe distances to be maintained when conducting operations near electric lines.  The question in each NAI has a reference to the use of spotters and low and high voltage

Regulation 3.64 (Overhead power lines, duties of employer etc. as to) of Western Australia’s Occupational Safety and Health Regulations 1996:

  • refers to voltage amounts and distances; and
  • makes no reference to spotters and low and high voltage.

Therefore in order to correctly complete assessments for HRWL applicants, Registered WorkSafe Assessors MUST replace the existing question with one that is based on regulation 3.64. 

The minimum safe distances to be maintained when conducting operations near electric lines, is a Critical Question.  Please correct this question immediately to ensure your NAIs reference regulation 3.64.

For your information, below are the following:

  1. A list of HRWL classes with NAIs which include a question in relation to minimum safe distances to be maintained when conducting operations near electric lines.
  2. A copy of regulation 3.64 Overhead power lines, duties of employer etc. from the Occupation Safety and Health Regulations 1996.
  3. The suggested replacement question for the NAIs which include a question in relation to minimum safe distances to be maintained when conducting operations near electric lines.

Regulation 3.64. Overhead power lines, duties of employer etc. as to

(1)     In this regulation —

danger zone means anywhere that —

(a)   is within 0.5 metres of a live insulated overhead power line or aerial bundled conductor line of a voltage of not more than 1 000 volts; or

(b)   is within 1.0 metre of a live uninsulated overhead power line of a voltage of not more than 1 000 volts; or

(c)   is within 3.0 metres of a live overhead power line, whether insulated or not, of a voltage exceeding 1 000 volts but not more than 33 000 volts; or

(d)   is within 6.0 metres of a live overhead power line, whether insulated or not, of a voltage exceeding 33 000 volts;

overhead power line means an overhead line for the transmission of electrical energy.

3.     The example question to adhere to Western Australian Legislation in the NAIs:

An example is provided for your reference to replace the questions noted in the table and should read as below:

Question for Western Australian clearance distances from overhead power lines

What are the minimum clearance distances that must be observed, as required by Regulation 3.64 of the Occupational Safety and Health Regulations 1996, when working near or in the vicinity of the following overhead power lines?
