Determination of Particulate & Dust Concentration During Shipyard Drydock Sandblasting Operations.

摘要

Testing was performed to determine the concentrations of total suspended particulate (TSP) and particulate matter smaller than 10 microns (PM1O) during a typical sandblasting operation. Testing was conducted at the Norfolk Shipbuilding and Drydock Corporation (Norshipco) located in Norfolk, Virginia, on July 14-15, 1992 under the direction of Thomas Beacham of Norshipco. Sampling was conducted by Patrick Slater and Everett Poore of Industrial & Environmental Analysts, Inc. (IEA) Research Triangle Park, North Carolina. Testing was observed by Ms. Lural Driver and Mr. Roy Huntley of the U.S. Environmental Protection Agency (EPA). Gravimetric analysis was performed by Clean Air Engineering (CAE) Analytical Services. Polarized Light Microscopy PLM and Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (SEM-EDX) analyses were performed by IEA, Inc., North Billerica, Massachusetts. A discussion of the project and sandblasting process is presented in Section 2. A summary and discussion of sampling results is included in Section 3. Sampling and analytical procedures are discussed in Section 4. Quality assurance/quality control (QA/QC) procedures are presented in Section 5. All field data, chain-of- custody forms, laboratory data, field logs, and equipment calibrations are included in the appendices.
