BUILDING MATERIALS
January 16, 1963
Hr. John T. Cantlon UO West Third Avenue Columbus 1, Ohio
Dear John:
Attached is the report from Mr. Fosdick which is excellent, and I
believe serves the purpose required. Considering he had only three days
this was quite a bit of territory to cover.
'
X am enclosing the separate information about compensation claims on the West Coast relative to Asbestosis for your background information. I don't think this ought to be given to anyone since it may not be public information, but you could relate the story if you want without identifying the name or the company. .
I thought you might like to make additional copies of Mr. Fosdick's report for the joint conference that would be held in Cincinnati. As you will note on page 9, it will take h.0 engineering days alone to take care of priority one in 11; areas. There would be the additional costs for the laboratory chemical analyses of the dusts.. After we talk together about 6 ' this I can contact Hr. Fosdick to get an estimate of costs.
personal regards.
Sincerely yours,
T?M:bn
Thomas F. Kancaso, M.D.
znc.
P.S. I found the bill, tucked in the main envelope, which I am new enclosing.

Table I summarizes the areas recommended for environmental evaluation on a
priority basis. As indicated, facilities in several of the areas vere not
observed in operation. Priority ratings for those areas have been based on
the types of operations involved, the materials used, the existence or absence
of exhaust control and zoom ventilation, end on the general appearance of the
area's dust spillage, rafter dust accumulation, etc.

The problem of-obtaining' representative camples is a complicated one. The time
^ % . . - Tiircd to obtain dust-samples usually is..of the order.of_minutes or;hours; .
while a period- of some months up to many years is generally required for the . "development of diseases from dusts. These.diseases result.from the integrated effect of dust brc-nthed over a long period. On-the other hand,-a single- in plant dus't-'dctcr;ndhat'Ion- -represents- 'only the: .amount of dualc in. the atmosphere ..
at- a definite time and place. It cannot give an indication of the average exposure of a man over a period of years -- particularly if he has not worked

continuously at the one job.
" ir
Thus a proper measure of dust exposures requires a picture of the variations in
dustiness -- the dust floods -- as well as a measure of the average concentration.

However, because of the .fibrous nature of asbestos, the th.cshaid licit cannot
be considered to be as firmly established as arc limits for seme of the other
J*
dusts. Techniques used for evaluating most other dusts (considered as spher
ical particles) may not be entirely valid for asbestos. The etiology of -
asbestosis still is under study ana research efforts arc vitally concerned with
the effect of the length and diameter of the fibers in producing lung damage.

oric large manufacturer of products using asbestos'evaluates a'ir samples taken in v. /plant for both dust and fibers. The respirable dust consicts of the more or less spherical particles 10 microns and Icsg in diameter, while the fiber, is . . considered to be those elongated" particles Greater than 20 microns in length.
A threshold limit of 5 million particles per cubic foot of air (mppcf) is applied
for the dust and 1 mppcf is applied to the fiber. (Tne 1 mppcf fiber threshold
limit is based on experimental vork conducted at the Saranac Laboratories,
Saranac, hew York and reported in "Experimental Studies of Asbestos is".) Inesc
juidc lines arc said to have worked out well based on this particular industry's
:linical experience.
