5 <br /> i <br /> Protective safety equipment for Levels D and C include the following: <br /> Level D - Mandatory <br /> • Steel-toed boots <br /> • Approved hard hat <br /> • Approved safety glasses with side shields, splash shield, or chemical splash <br /> goggles <br /> • Long pants <br /> Level D - At discretion of Qeraghtty & Miller Site Health & Safety Qfflcer <br /> • Tyvek coveralls <br /> • Plastic-coated Tyvek coveralls <br /> Level <br /> • All required Level D protective equipment <br /> • Air-purifying cartridge-equipped respirator(half- or full-face respirators) <br /> Air-purifying respirators are to be used only in conjunction with air monitoring in the <br /> breathing zone and with strict adherence to action levels listed below. Air-purifying respirators <br /> may only be used when the device affords protection from the substances encountered. It is <br /> anticipated that respirators will provide adequate protection for the conditions that will be <br /> encountered site activities. However, if action levels exceed a respirator's-capacity, the work <br /> will be suspended until personal protective equipment can be upgraded to supplied air <br /> (Level B). <br /> Respirator Use and Maintenance <br /> Respirators issued to individuals will be cleaned and disinfected at least daily, if used. <br /> Where respirators are used by more than one person, the respirator will be cleaned and <br /> disinfected after each use. Respirators will be inspected during cleaning, and any necessary <br /> repairs will be made at that time. Damaged respirators will not be worn. After cleaning, <br /> respirators will be placed in clean, plastic bags and stored in a clean location convenient to . <br /> work areas. <br /> Al <br /> MONITORING <br /> Air monitoring will be performed during the drilling and sampling activities. By <br /> comparing the information obtained from the monitoring with the action levels described <br /> below, the safety of environmental conditions in the work zone will be assessed. <br /> Project No. RCO291.001 <br /> GERAGHTY&MILLER.
