Subject: Letter of 4/8/69 to Mr. J* H. Bierer, President Pittsburgh Corning Corporation, Re: Survey Plant - Tyler* Texas - 2/13/69
Dear Mr, Blair:
The following action is being taken to correct the unsatisfactory conditions noted in Che report dated February 13, 1969,
1, Code Standard - Ref* 50-204,264
All supervisory employees were enrolled in a first aid course given by the American Red Cross with the first session given 4*10-69. The course is to consist of three sessions and by 5-26-69 there will be fully qualified personnel on all shifts.
2. Code Standard - Ref. 50-204.275
Pittsburgh Corning Corporation uses the services of Lee B. Grant, M.D., Medical Director, PPG Industries, and his staff, to monitor its production facilities for compliance with A.C.G.I.H. threshold limits for dust concentrations. (See attachments II and III). In addition, the Industrial Hygiene Foundation conducts periodic dust measurements to ascertain the dust concentrations present. (See attachment I).
For those areas in which dust concentrations exceed the thresh Id limits, it is required, as a condition of employment, that each employee wear a Dust Foe #55 Respirator #CM-73020 approved by the 0. S. Bureau of Mines.

2. Code Standard (continued)
In reference to the sentence of your report where you state, It is believed that the present system is below the required capacity", the dust measurements do not support this belief. Pittsburgh Corning Corporation retains the services of Or. Morton Com, a consulting engineer and authority in zie. field of industrial hygiene and air pollution. Dr. Corn approves all new installations as well as any modifications of our dust collecting systems.
If you should need any additional information or there is ne*ed for additional surveys, please advise.
Yours very truly
