Nitrile gloves and tyvek/saranex suit should be worn if contact with contaminated water or soil is likely. <br /> 3. Hearing protection must be worn if noise levels prevent normal conversation at a distance of three feet. <br /> 4. No eating or drinking is allowed in the exclusion or contamination reduction zones. No Smoking anywhere on site. <br /> 5. No Miller Brooks personnel shall conduct a confined space entry.

Respiratory protection is dependent on conditions listed below Section VI1.B.3. <br /> B. SURVEILLANCE EQUIPMENT AND MATERIALS: <br /> 1. Calibration: A qualified individual will calibrate before and after field activities the photoionization detector(PID) or flame <br /> ionization detector(FID). Document the calibration in the attached log in Appendix C. <br /> 2. Frequency: The breathing zone of Miller Brooks employees on-site will be monitored every hour (at a minimum) and <br /> recorded in the attached air monitoring log in Appendix C. Monitoring should be conducted during tasks that may result in <br /> exposure to vapors. If vapors are detected in the work area, the perimeter of the exclusion zone will also be evaluated <br /> and adjusted as needed. In addition, vapor detection will warrant implementation/modification of vapor suppression <br /> measures. <br /> 3.
