Vestas Safety Regulations for Operators and Technicians - Don Airey email

Issued by: Technology Safety Regulations for Operators and Technicians Class: II Type: MAN V90 — 3.OMWNIOO — 2.75MW Page 3 of 32

I. Introduction

A turbine connected to the grid implies certain elements of danger if it is handled without exercising proper caution.

For safety reasons, at least two persons have to be present during a work procedure.

The work must be properly carried out in accordance with this manual and other related manuals. This implies, among other things that personnel must be instructed in and familiar with relevant parts of this manual.

Furthermore, personnel must be familiar with the contents of the “Substances and Materials” regulations.

Caution must especially be exerted in situations where measurement and work is done in junction boxes that can be connected to power.

Consequently the following safety regulations must be observed.

2. Stay and Traffic by the Turbine

Do not stay within a radius of 400m (1 300ft) from the turbine unless it is necessary. If you have to inspect an operating turbine from the ground, do not stay under the rotor plane but observe the rotor from the front.
Make sure that children do not stay by or play nearby the turbine. If necessary, fence the foundation. The access door to the turbine must be locked in order to prevent unauthorised persons from stopping or damaging the turbine due to mal-operation of the controller.

3. AddressandPhoneNumberofthe Turbine

Note the address and the access road of the turbine in case an emergency situation should arise. The address of the turbine can often be found in the service reports in the ring binders next to the ground controller. Find the phone number of the local life-saving service.

We have just learned that Invenergy is saying they pulled the VESTA info. at VESTA's request due to the info. being "proprietary" in nature.

We have access to a hard copy of the rest of the manual. It is contained in the application to Roxbury and Stamford. Invenergy pulled the manual from their site, after they learned we were quoting it.

That document was instrumental in getting the R-Ville Committee to recommend 1500' from property lines.

Pound the fact that property owners should have reasonable expectation of safety while on their property. Also not the 1300' for workers assumes they would only be near the turbine for short periods of time, only a few times per year.
