From: E.C.J. Urban
Subject: Prelininary Industrial Hygiene Survey, ^.Onens-Tllinois_Glass Company. `` r.ayio_Division Plant, Sayreville, II. J.
The survey work was requested by Ur. TT. Hazard of the OwensIllinois Glass Company, Toledo, Ohio, office.
Members of The Saranac Laboratory staff participating in the survey were: T.M. Durkan and E.CoJ. Urban.
The following individuals were contacted at Sayreville. Ur. O.TT. Pfeifer. Plant Manager iir. Tfm-ipjn ferker, PersontjJl Manager
llr. P.E. Gillis. Safety Director Ur. John Roades, Quality Control Engineer The survey was made in the company of Ur. i7. Hazard. Its purpose was to examine the plant operations with the view of discovering ary hazards to health which might exist as the results of the raw
materials handled and the finished product produced.
Raw Materials
1. Diatomaceous Earth
The products of several U.S. manufacturers including Johns-
Danville. The earth was not a pure" product (100 SiC2)
but contained contaminants as clays.
2. Silica flour (high grade of free crystalline Si02 ground to
a fine size) from Pennsylvania Pulverizer Company.
3. Tripoli (small quantities) from Illinois Mineral Coapany.
Ii. Lime, Warren Conpary, Balfont, Pennsylvania.
5. Asbestos, Chrysotile, Johns-Kanville-Quebec, Canada
!
Asbestos, Amosite (iron bearing) South Africa.
6. Kayolin (clay) small amounts from Georgia.
7. Cement, commercial grades.

Finished Products "Kyle" product in tile forms for structural uses. Reinforced
with wire for roofing. Sheets for fire-proof doors and panels. In round forms for pipe insulation covering. Two types of "Kaylo" were made. "Light density" and PHeavy density". Both contain different mixtures of the same original components.
The quality of the finished product is fudged by structural -

strength, density, hardness and moisture absorption.
Seven dust counts were taken in strategic locations through out the plant. Seven sites were selected at which air-bome sample collections rill be made (vacuum cleaner on filter paper), by lb*. John Roades. The samples rill be forwarded to The Saranac Laboratory for analysis.
The sketch. Fig. I, shows the locations of dust counts #1
to 7 inclusive and the air-borne sample collections fib to Hi
inclusive.
Bulk samples of all the main ram products used and of Light and Heavy Kaylo grades were also obtained for analysis.
T/e believe that two main health hazards must be considered in this plant. Asbestos (long fiber) and crystalline free silica.
^th Hr. Hazard requested six (6) copies of a formal report of this survey be sent to him. The cost of this work was not discussed
