TITLE:
EVALUATION OF CONTRACTOR WORK HABITS USING AREA MONITORING FOR ASBESTOS DURING A TRANS ITE BOARD REMOVAL PROJECT AT TEXAS OPERATIONS-MAGNESIUM CASTING A, (A-629), ON MARCH 22 AND 30, 1988.
Asbestos area monitoring was performed during the removal of a transite board project at Magnesium Casting A, (A-629), on March 22 and 30, 1988. All area sample results were less than the acceptable exposure guidelines of 0.2 fibers/cc. Results of the eight samples taken ranged from <0.0002 to 0.12 fibers/cc with an average of 0.019 fibers/cc.
The procedures outlined in the Texas Operations Asbestos Handbook - February, 1987 were followed during this removal project by Win Way-Contractors. The work area was cordoned off and all workers within the restricted area used approved respiratory protection and protective clothing. Disposal and clean-up operations followed the handbook guidelines.

EVALUATION OF CONTRACTOR WORK HABITS USING AREA MONITORING
FOR ASBESTOS DURING A TRANSITS BOARD REMOVAL PROJECT AT
MAGNESIUN CASTING A, (A629), ON MARCH 22 AND 30, 1988
INTRODUCTION
On March 22 and 30, 1988, Win Way contractors removed transite board From Magnesium Casting A, (A-629), ceiling. Area monitoring was conducted to evaluate potential exposures to asbestos during this operation.
CONCLUSIONS
All area sample results were less than the acceptable exposure guidelines of 0.2 fibers/cc. Results of the eight samples taken ranged from <0.0002 to 0.12 fibers/cc with an average of 0.019 fibers/cc. Monitoring results have been communicated to Win Way Contractors for employee notification. See Table I for sampling results.
ST00I5I94
RESULTS AND DISCUSSION
Win Way contractors removed transite board from Magnesium Casting A ceiling, following procedures in the Texas Operations Asbestos Handbook - February 1987 Guidelines. The actual removal process lasted two days and occurred on March 22 and March 30, 1988.
Scaffolding and decking was erected to perform this removal project. A double layer of clear poly was laid out on the decking and attached to the scaffold's mid-rails. Prior to removal, each transite board was wetted with amended water. Once removed the transite was placed on a double layer of poly, wrapped and secured. The wrapped transite was lowered to the ground and placed in a dlno box for disposal. The poly on the scaffolding was rolled up and properly disposed of with the work area being thoroughly cleaned.
Approved respirators and protective clothing was worn by all operators involved within this restricted area.
METHODOLOGY
Asbestos samples were collected using calibrated Gilian HFS 513 air sampling pumps. A known volume of air was pulled through 25 mm cellulose ester membrane filters, 0.8 micron pore size. Samples were collected at a flow rate of approximately 2 liters per minute. The samples were counted by McKee Environmental Health Services using NIOSH Analytical Method #7400.

FOR ASBESTOS DURING A TRANSITE BOARD REMOVAL PROJECT AT
MAGNESIUM CASTING A, (A629), ON MARCH 22 AND 30, 1988
EVALUATION CRITERIA
The evaluation of exposure levels was based on the following criterion:
Asbestos
_____ OSHA PEL 0.2 fibers/cc
The OSHA Permissible Exposure Limit (PEL) is the time-weighted average concentration for a normal 8-hour workday, 40 hour work week, to which nearly all workers may be repeatedly exposed without adverse health effects.

PROCEDURE POR THE REMOVAL OF TRANSITE FROM CEILING OF A-629
1. All rules and regulations as per the TEXAS OPERATIONS ASBESTOS HANDBO shall apply where relevant.
2. This will be a large scalei long duration job with the exception of a negative air enclosure.
3. The entire area shall be worked in sections, (ex: 1/A at a time. etc.
A. Scaffolding shall be erected in such a fashion as to solidly deck the area to be stripped.
5. Clear poly (doubled layered) shall be laid out on the decking and attached to the scaffold's mid-rails.
6. Prior to removalt each transite sheet shall be wetted with amended water.
7. The transite shall then be removed from the ceiling using a pry bar. (Care should be taken to avoid breaking any transite material.)
8. Removed transite shall be placed on a double layer of poly which is large enough to be wrapped around several stacked sheets of transite and secured.
R. The wrapped transite shall be lowered to the ground by a rope and placed in a dino box for disposal.
10 At the end of the dav the wok area shall be thoroughly cleaned. The
poly on the scaffold shall be rolled up and properly disposed of.
