Attention: Del Jones

We reviewed lighting fixt+Ire installation methods in one hour fire
rated ceilings with Vic Paolino, Mason County Deputy Fire Marshal ,
by telephone on July 20, 1978.
It was determined that the provisions of Paragraph 4303,B.6, "Ceiling
Protection', of the Uniform :3uildinq Cade would apply, and that
lighting fixtures would be protected as folloa-rs:
1 . Recessed Fluorescent Fixtures: Install a flat panel
of plasterboard on top of eac'i fixture, cut at
least 6 inches larger than the fixture opening.
2. Recessed Incandescent fixtures: Install a plaster-
board tent over each fixture, constructed with a
taped peak and open triangular ends.
These construction methods were determined to satisfy the intent
of the of the U3C and still provide the necessary ventilation to
maintain lamp and ballast and life, in addition to protecting the
fixtures from excessive heat build-up that would be encountered
if the fixtures were fully enclosed as specified.
We further reviet4 d these construction methods with Gordon Cochran
of Cochran Electric, and it was agreed that both incandescent and
fluorescent fixtures would be protected as described at no change
in the contract amount, instead of only the incandescent fixtures
as specified.
