<br /> BUILDING �1ND F'II� llEPAR^1MFNT5 REPORT ON BUILDERS EXCHANGE RECOMMENDATION REGARDING USE OF -"
<br /> PLYWOOD IN INTERIOR FINISH. The Clerk read the following letter:
<br /> "In reference to the request from the Builders Exchange as to the use of
<br /> Plywood as an interior finish, no provision has been made in the Uniform
<br /> Building Code covering the interior finish of dwellin�s in Fire Zone No. �
<br /> 3• ',
<br /> Chapter 42 of' the Uniform Buildin� Code pertaining to wall and ceiling
<br /> ,�, finish makes provision as to its use under Fire Protection of various
<br /> materials in all groups from "A" to "H" inclusive. Dwellings, which come
<br /> ,� iinder Group "I" have no restrictions. However, there are some conditions
<br /> that are created by the use of plywood that should be considered. _
<br /> Plywood burns rather readily and has very little fire-retardent qualities
<br /> especially in the smaller thickness. The real hazard of plywood is the
<br /> tendency to maintain the natural grain of the wood which is done by the
<br /> use of waxes, plastic, varnish, shellac, lacquer, �etc. These finishes
<br /> ,,.... are conduci�e to creating fast burning surfaces when heat is applied,
<br /> more so than on painted surfaces.
<br /> � The use of fire retardent materials behind the plywood will have no value
<br /> in retarding the fast burning action of the above finishes and therefore
<br /> there is very little gained by this procedure. , If it were possible to en-
<br /> force the application of fire-retarding finishes on the plywood surfaces
<br /> it would be ideal but the inspection problem would be tremendous and very,
<br /> impractical. _
<br /> There is no question from a part of fire fi�hting control that the fire-
<br /> retardent materiaZs are safer, losses are keptoto , a minimum and occupants ',
<br /> have a greater degree of safety in c ase of hurried exits during emergenc- I
<br /> ies. The proposal as submitted by the Builders Exchange would be, to a
<br /> small degree, helpful but questionable as to retarding factors on the ,
<br /> living side of the wall. '�
<br /> It is our combined opinion that as long as this matter could be brought ',
<br /> before the Pacific Coast Building Offcials Conference, it would be wiser '
<br /> for this group to study this matter and submit their findings for regula-
<br /> tions. We also suggest that the request as submitted by the Builders Ex- '
<br /> change be forwarded to the Pacific Coast Building Officials Conference
<br /> for their attention.
<br /> Very truly yours,
<br /> S. H. KREISS
