Periodic Assessments of Electrical Installations under ESR 75
Aidan Thornton made this Official Information request to WorkSafe New Zealand
Currently waiting for a response from WorkSafe New Zealand, they must respond promptly and normally no later than (details and exceptions).
From: Aidan Thornton
Dear WorkSafe New Zealand,
I am writing in regards to Peridic Assessments required under Regulation 75 of the Electrical (Safety) Regulations 2010: https://www.legislation.govt.nz/regulati...
I believe this is predominantly handled by the Energy Safety division within WorkSafe.
1) Does WorkSafe have any programs to ensure compliance with this regulation, or any opinions/studies on compliance rates? If so, please provide.
2) Has WorkSafe carried out any enforcement action on those who have not had facilities adequately inspected? Please provide general statistics, or cases if minimal.
3) In relation to 75 (2), who does WorkSafe believe is "authorised to assess prescribed electrical work on the relevant kind of installation in the relevant location"? This includes any legal opinions on the matter.
4) Has WorkSafe carried out any enforcement action on those who have carried out periodic assessments improperly, or without appropriate training, qualifications, experience, or skill? Please provide general statistics, or cases if minimal.
5) In relation to 75 (1) (c), (e), and (f), how often would WorkSafe expect these facilities to be assessed where the standard does not give guidance?
6) Does WorkSafe believe that an installation's first periodic assessment is required to be immediately on practical completion, after the defined period (e.g. 1, 5 years) has elapsed after practical completion, or at some other time?
Thank you for your consideration of this matter.
Yours faithfully,
Aidan Thornton
