Caapagna Davis Fraser Henry
Ob March 5* 1971* Mr* Henry and X visited tha Naval Ship Snglaeering Center la Hyatteville, Md. Our purpose was to discuss the Navy'o Interest la an asbestos fres ealciun silicate thermal insula tion. Zn general, we found in our discussions that the Navy was very interested la the subject product* They are eurreatly revising their specification.-; to exclude high asbestos content products (Unibestos) Further, they expect st some point in the future to exclude say asbestos containing products. They also indicated that any new products would have to cosply with military specifications as well ae receive approval froa the Kavy Bureau of Kedieiae l Surgery. Mr. Henry and Z talked briefly with Coemaader Sarboo of the Bureau of Kedieiae who outlined to us how ws would go about receiving approval of our product by his departseat.
In general, vs found that the Navy was Interested in approving our new produet but not interested in launching a joint test prograa to dsterains If our new product was acceptable in service.
Mr. Hnxy and X agreed to write to Mr. Henry Murad of Navy Ship ^Engineering Canter to eonflru the fact that we were considering the subject product and confining our discussion. X believe'we are both agreed that it would be preaature for us to take the next steps toward qualification of our new product until we are sore confident and until we have nore field experience with the test-quantities of asbestos free ealsilite.

8. Must bt vermin proof.
9. Tbe material sad application costs should ho eccacoleal.
10. The ideal insulation should he nantoxic and noa-injurious to personnel during fabrication, installation, use, or rip-out.
11. Once Installed, it should not cluster, beeone lumpy, disintegrate or build up in masses from vibration.
The Philadelphia Division of the Naval Ship engineering Center has been assigned tasks to conduct a survey of suppliers of insulation to the Navy, to secure technical data literature, sad to investigate medical research findings, safety manuals, end data on research being pursued by private industry intended to develop an or improved materials vhich may be suitable for replacements for asbestos for piping, felts and lagging. The cooperation and support of industry for this study is earnestly solicited by this activity since tbe health of tbe vsrker le the concern of management, labor and the government. Accordingly, the Navy is desirous of obtaining information on the following:
a. Are alternate non-asbestos containing materials available vhich may be used as thermal insulation pipe covering? The insulation must offer protection up to 750 F end be manufactured in cylindrical sections up to 3 feet long, end split In half lengthwise.
b. Are there any single layer or combination layered non-asbestos molded materials available vhich may be used as thermal inaulaticn pipe covering for protection from 750 to 1200 F?
e. that materials may be substituted for asbestos insulating felt (plain or vater repellent) for use on valves or other Irregular surfaces end vhich are suitable for e range from cold vater temperature to 900 F?
d. That non-asbestos containing cloth materials may be used as a legging jacket ever thermal insulation, or as a vrapplng on engine exhaust pipes, or for piping or tubing, or on the inner end outer surfsees of removable covers end on flanges cad valves from -5 F to 1050 F?
e. That heat resistant bonding materials may be substituted for asbestos insulation finishing cement over block insulation end irregular surfaces vhere powdering during rlpout has been e problem?

f. That safety precautions to prevent Inhalation of dust are observed during the manufacturing and processing of insulation saterials?
g. Vhat safety precautions are reesnended during the installation and replacement of insulating aaterlals to prevent the inhalation of asbestos fibers and dust?
h. 1b ehat extant or degree sill aaterial and installation costs be effected by the ellninatian or curtailment of tha use of asbestos containing insulation?
Due to ths urgency of this undertaking, it la requested that the above Information be forwarded at your earliest convenience to Dr. if. Ansuth, the project engineer of this task, at tha Naval Ship Engineering Canter, Philadelphia Division, 6764, Philadelphia, Pa. 19112 (telephone ntaaber (213) 753-J922). Information submitted to the Philsdelphia Division of the Naval Ship feiginecrlng Oenter will be utilised by the Naval Ship Systarns Comoand In proeulgatlnc a directive which will eliminate the use of materials and practices whlehsrs potentially hasardous to the health of insulation workers. This activity has bean directed to complete the survey of insulation suppliers by 13 June 1969 to afford time for collation and personal contact. If deemed necessary.
Please be assured that any produet composition and- formulae submitted in response to this survey, will be held in strict confidence and will be viewed as a voluntary contribution to this perplexing problem to the insulation Industry. It is understood that submission of information solicited by this activity will not obligate the government or its agencies in any manner whatsoever.
cry truly yours,
