Standard Operating Procedure Installation and Extraction Vapor Pin® Sampling Device Scope & Purpose Scope Purpose This standard operating procedure describes the The purpose of this procedure is to assure good quality installation and extraction of the Vapor Pin®Sampling control in field operations and uniformity between field Device for use in sub-slab soil-gas sampling. personnel in the use of the Vapor Pin®Sampling Device. Equipment Needed • Vapor Pin®Sampling Device 0 3/4-Inch (19mm) diameter bottle brush • Vapor Pin®Sleeves 0Wet/Dry Vacuum with HEPA filter(optional) • Vapor Pin®Cap Dead Blow Hammer • VOC-free hole patching material (hydraulic cement) • Installation/Extraction Tool and a putty knife or trowel • Rotary Hammer Drill o This is for repairing the hole following the 0 %-Inch (16mm) diameter hammer bit extraction of the Vapor Pin®Sampling Device 0 1'/2-Inch (38mm) diameter hammer bit for flush mount applications Installation Procedure 1. Check for buried obstacles (pipes, electrical lines, etc.) prior to proceeding. 2. Set up wet/dry vacuum to collect drill cuttings. 3. For a temporary installation, drill a %-inch (16mm)diameter hole through the slab and approximately 1-inch (25mm) into the underlying soil to form a void. The hole must be %-inch (16mm) in diameter to ensure a seal. • If a flush mount installation is required, drill a 1'/z-inch (38mm) diameter hole at least 13/-inches (45mm) into the slab. We highly recommend using the Stainless Steel Drilling Guide and to reference the Standard Operating Procedure Drilling Guide & Secure Cover. 4. Remove the drill bit, brush the hole with the bottle brush and remove the loose cuttings with the vacuum. 5. Assemble the Vapor Pin®Sampling Device and Vapor Pin®Sleeve (Figure 1). 6. Place the lower end of the Vapor Pin®Sampling Device assembly into the drilled hole. Place the small hole located in the handle of the Installation/Extraction Tool, over the Vapor Pin®to protect the barb fitting and tap the Vapor Pin® into place using a dead blow hammer(Figure 2). Make sure the Installation/Extraction Tool is aligned parallel to the Vapor Pin®to avoid damaging the barb. • During installation, the Vapor Pin®Sleeve may form a slight bulge between the slab and the Vapor Pin® Sampling Device shoulder. 7. Place the Vapor Pin®Cap on the Vapor Pin®to prevent vapor loss prior to sampling (Figure 3). 8. For flush mount installations, cover the Vapor Pin®with a flush mount cover, using either the plastic cover or the optional Stainless Steel Secure Cover(Figure 4). 9. Allow 20 minutes or more (consult applicable guidance for your situation)for the sub-slab soil-gas conditions to re-equilibrate prior to sampling.
