SITE HEALTH & SAFETY PLAN <br /> Level C: Should be selected when the types of airborne substances <br /> are known, the concentration is measured, and the criteria for using <br /> air-purifying respirators are met. <br /> Level D: Should not be worn on any site with respiratory or skin <br /> hazards. It is primarily a work uniform providing minimal <br /> protection. <br /> C. Required Protection <br /> It is anticipated that level C work clothing (P.E. Tyvek or similar) . <br /> will be worn during the monitoring well installation phase of the <br /> project:. In addition, however, the personnel working on the project <br /> will be required to wear surgical. under gloves (latex), and chemical <br /> outer gloves. As the project involves the drilling of soil borings, <br /> and the installation of ground water monitoring wells, the <br /> potential exposure anticipated is with the contact with potentially <br /> contaminated soils and ground water. Historical analytical data <br /> indicates this potential contamination to be in the low part per <br /> i <br /> million range (Except near the tanks where moderate . to high readings <br /> were recorded.) . <br /> Should the readings with the PID indicate the presence of <br /> contaminated materials near the TLVs of the materials analyzed, or <br /> approaching the 75-100 ppm range of total organic compounds, the <br /> personnel assigned to the project will upgrade their personal - <br /> protection with appropriate clothing and respiratory protective <br /> equipment. That equipment will include the selection of the proper <br /> cartridges for the anticipated exposure. <br /> - 1 <br /> 14 <br /> I <br />
