GENESIS ENGINEERING& REDEVELOPMENT <br /> minimum frequency for VOC monitoring in each work area will be once every 30 minutes <br /> during initial drilling,well installation, and groundwater sampling activities. If an individual <br /> Site location shows no indications of contamination above background,VOC levels may be <br /> monitoring daily, at the discretion of the CHSO. <br /> All monitoring instruments will be calibrated daily before use, consistent with the manufacturers' <br /> recommendations and all results shall be recorded in a field logbook. <br /> 5.0 PERSONAL PROTECTIVE EQUIPMENT <br /> Using the appropriate PPE will minimize the potential hazards from exposure to chemicals of <br /> concern. The minimum level of protection selected for the project is Level D, as defined by the <br /> USEPA(July 1988). Level D protective equipment is used on sites that have been investigated <br /> and characterized as posing occupationally insignificant skin or respiratory hazards, and for <br /> which all criteria for the use of air-purifying respirators have been met. Dermal protection will <br /> be required when direct contact with potentially impacted materials is possible to prevent <br /> unnecessary exposure. <br /> The protection level at the project area may be upgraded to Level C, as specified by the Field <br /> Team Leader or CHSO, based on air monitoring results as outlined in Section 4.0. <br /> The appropriate PPE must be worn during all field activities associated with this project. It is <br /> anticipated that drilling activities will require personnel to be suited in Level D PPE. Level D <br /> consists of the following: <br /> Level D <br /> • Safety glasses or goggles <br /> • Hard hat <br /> • Steel-toed boots <br /> • Long pants <br /> • High-visibility traffic vests <br /> In addition, chemical resistant (nitrile) gloves are required when handling soil or groundwater <br /> samples. <br /> The following PPE will be readily available for use as necessary based on monitoring results <br /> outlined in Section 4.0: <br /> Health and Safety Plan 9 of 16 <br /> DePaoli Property <br /> November 14,2007 <br />
