AFFIDAVIT OF LAWRENCE M. JACOBSON I, Lawrence M. Jacobson, being on oath, depose and say as follows:

1. I am a Maintenance supervisor at Seabrook Station.

My supervisory responsibilities include maintenance of the New Hampshire and VANS sirens, since completion of the New Hampshire system's installation in late 1986. A statement of my professional qualifications is attached hereto and marked "A".

2. The design of the dual siren system rotation mechanism, control cabinets, siren horn assenbly, ar.d misenllaneous hardware, used in the VANS (with respect to cold weather operation and weather tightness) are the same as

[kM 0 PM 4::

or similar to the Whelen siren systems installed in

. The purpose of my affidavit is to discuss the operating history of the sirens as it relates to snowy, icy and extreme cold weather conditions, i 3. The rotation mechanism is in a weatherproof housing and is effective in keeping out rain and snow regardless of the operating position.

4. The Mass AG was informed by that weather conditions don't impede operation and that these alarms are all over the world including Alaska (see attachment marked "B").

J 5. The maintenance program for the sirens located in I is comprised of a bi-weekly silent operational t

check, a quarterly preventive maintenance examination, and an

annual component inspection and alignment. The silent operational check exercises all siren functions including siren rotation.

6. Review of the siren maintenance records has identified no failures of the weather tightness design of the control cabinets, siren housing covering the drivers r

or the rotating mechanism. There have been no component failures attributable to cold weather operation or to the entry or accumulation of snow, ice, or water, ,

7. Given the performance of the siren systems installed in the , and exposed to the i

I e

M e

t elements over the past years, it is reasonable to expect that the dual siren system utilized by VANS wil.1 perform similarly well. That is, I do not expect i

operation of the dual siren system to be impeded by snowy, icy, or extrema cold weather conditions or by the accumulation of snow, ice, or sleet. [

l Lawrence M. Jacobson Professional Qualification I have over thirty years of maintenance experience on the emergency-plan sirens. I have over thirty years of maintenance experience dealing with electronic and electro-mechanical systems. The majority of these systems were l portable and many were housed in weather tight containers. '
