AIRBORNE ASBESTOS COUNTS for
Union Carbide Corporation Niagara Falls. New York Bldg. #169

OBJECTIVE: To determine airborne asbestos fiber concentrations within a
production area containing an asbestos pilot plant operation. Production of asbestos products In this area had last been conducted In 1975. DESCRIPTION OF OPERATION:
Five environmental samples were obtained In Building #169 at the pilot plant location and within the general work and storage areas. Sampling was conducted during sample preparation activities (not concerning asbes-tos) on a normal work day for eight hours.
Sample locations are found on Figure 1.

. s SAMPLE EQUIPMENT AND TEST PROCEDURES t Sampling and dust counting are carried out In accordance with OSHA Regulation 1910.1001, based on NIOSH Analytical Method P&CAM 239 and OSHA methods; reference - Occupational Safety and Health Administration.Methods, W. C..Dixon431, MBS special publication No. 506, U.S. Department of CofflrtieWft; Nbvember 19/8;: 'r
Battery-powered air pumps (M.S.A. type), calibrated to 2 liters per minute, are used to collect personal breathing zone and environmental samples on Mllllpore membrane filters of 0.8 micron porosity. Fiber counting Is performed on a Niton phase contrast microscope at 400X utilizing a Porton reticle for sizing and field definition.
Two results have been reported for each sample - they are:
1. Chrysotlle Asbestos - All fibers having an aspect ratio *3 and a length >5uthat are In the operator's judgement, chrysotlle. In the event of doubt or the absence of further Information, any fiber having the above
. physical dimensions Is counted as chrysotlle.
2. Possible Amphibole Asbestos - All amphibole asbestos fibers having an aspect ratio >3 and a length >5y. In the event of doubt or the absence of further Information, any fiber of similar appearance and dimensions is counted as amphibole asbestos.
COMMENTS
The OSHA regulations permit a maximum limit of 2 fibers greater than 5 microns in length per-cubic centimeter of air sampled on the basis of an 8-hour, time-weighted average (TWA). The formula C-jT-j + CgTg + CnTn describes the TWA where C fiber count
_
in fibers/cc and T= time.
The regulations also stipulate a ceiling concentration of 10 fibers/cc greater than 5 microns which Is not to be exceeded at any time.
LIMITS AND CONDITIONS
1. In compiling this report. Union Carbide followed procedures which it believes to be accurate and reliable but there may be other methods for evaluating asbestos fiber emissions which may produce different results.
2. The air monitoring results reported herein are not necessarily representative of the results which may be found at different locations or under different operating conditions.
3. Any use of or reliance upon the data or other Information contained herein by yourself or any other party shall be without any recourse to or liability on the part of Union Carbide.
4. The breathing of asbestos dust may cause serious bodily harm and Union Carbide makes no warranty or guarantee that the results contained herein indicate safe levels of exposure. It Is the responsibility of any user of asbestos or asbestos-containing product to ensure that safe handling procedures are employed and that applicable government regulations are complied with. Ap propriate literature and other information concerning asbestos and health or regulations are available upon request.
5. Regardless of the results of these tests you should consider the advisability of further air monitoring.
TEST RESULTS
The details of sample collection and resultant fiber counts are listed in the attached table(s).
