Bell, Or. 19 East Asbestos All of our diaphragm cell plants are being audited to assure that they are in compliance with the OSHA asbestos standard. In many instances, we are taking extraordinary measures to minimize exposures. I feel that this area development is coining along nicely. As for our practices in insulation, I was just getting around to this when the vinyl chloride news broke. There are certain programs that should be completed at Lake Charles, Barberton, Natrium, and Corpus Christi. Zeb G. Bell, Jr. ZGBrmal cc: D. D. Dupre \Ji p | BB 0013961 | INDUSTRIES To: fu_J.

Bell, Jr. Location: "]Q ^est subject: Amorphous Siicas TLV /V> Tnere has been considerable.discussions concerning the appropriate Threshold Limit Values for synthetic amorphous silicas among producers, users, NIOSH, OSHA, etc. To clarify the present status, the following information is provided. The present OSHA standard for amorphous silicas is 20 mppcf. The 80/% SiO? has been misused by OSHA, and PPG has a letter from OSHA stating that this standard (80/% Si02) is not applicable. It is possible for OSHA under the general duty clause to apply the latest consensus standards from such sources as the ACGIH. The ACGIH TLV is 10 mg/m^ for. total inert dust. The ACGIH TLV corrmittee has proposed a notice of intended-change for amorphous sili cas and diatomaceous earth of 3 mg/m^ total dust and 1 mg/mJ respirable fraction. This isbeing contested by the industry as being unnecessarily restrictive since it is documented on only diatomcceous earth data.

Kuryia to come to Lake Charles with proper stack sampling equipment and sample fiain for making particulate measurements being emitted from each of the pigment plant stacks. REASON FOR EXPENDITURE State of Louisiana has indicated to us 1 hat Lake Charle,- area has high particulate in ambient air. FPG will, from this study, determine paiticulcte stack emissions.

DISCUSSION The Threshold Limit Values stated in LD-1121 are recommended by the American Conference of Governmental Industrial Hygienists and are expressed as "parts of vapor or gas per million parts of air by volume" or "milligrams particulates or aerosols per cubic meter of air" at 25C and 760 mm Hg. The reported values in this report are expressed in the same units. Sampling time varies greatly, depending on the method of detection and the concentration of contaminant present, but listed below are approximate sampling periods for given contaminants: Ammonia Chlorine Chlorine-Chlorine Dioxide 1,2-Dichloroethane Ethylene Hydrogen Chloride Lead Mercury 4 hours 4 hours 4 hours 3 to 6 minutes 3 to 6 minutes 4 hours 6 to 48 minutes Lemaire Sniffer: Unico Tubes: Monitaire Tubes: Instantaneous 3 minutes 4 hours Methyl Chlorofom Particulates - 3 to 6 minutes - Electrostatic Precipitation: 5 to 30 minutes Monitaire Samplers: 1 to 4 hours Perchloroethylene Phosgene NaOH Mist Trichloroethylene Vinyl Chloride 3 to 6 minutes 3 to 6 minutes 6 hours 3 to 6 minutes 3 to 6 minutes Author: 3//1/70 Ddte / r MW:rw | BB 0013960 |
