12. Air Monitoring AIR MONITORING Air monitoring shall be performed to evaluate air emissions at the site. The SSHO shall determine if an industrial hygiene evaluation or additional sampling is needed to assess health and safety at the site. The SSHO will assist the Project ME nager/Onsite Project Lead on determining when monitoring shall be performed to ensu-e site health and safety. Air monitoring to determine the presence of combustible gas (monitoring shall be on-going) or oxygen deficiency shall be performed with an appropriate air monitoring instrumentation, such as a RKI Eagle. If a reading of 10% of the lower explosive limit (LEL) is met, then all work shall cease and then all personnel in the exclusion zone be moved to the upwind side of the CRZ where LEL is less than 10°1. The SSHO would then commence assessment to determine'the potential risk of explosion. At the Lodi City Landfill site, Health and Safety staff will require clean-up staff to use a passive gas monitor for hydrogen sulfide and combustible gas while trenching at sites formerly used for wine waste disposal (At locationsT8 through T1 ), LFG 7, 8 &10). If an alarm is triggered, all work must cease and the SSHO would commence assessment to determine potential risk. The "mini RAE"/photo ionization detector(PID) indicates if volatilE organic compounds are present. The PID should not be used to detect semi-volatile c)mpounds including but not limited to PCB's and PAH's. Keep in mind that rain may F-ffect performance and high humidity can cause lamp fogging and decreased sensitivity. High concentrations of methane can hinder performance. Because it is likely we are cealing with unknowns, if the reading is 5 ppm above background level in the breathing zone, all work should be stopped and evaluation situation should commence. All instruments used for air monitoring shall be calibrated prior to use and the calibration log and sampling results shall be properly maintained. RADIATION MONITORING The decision to monitor for radioactive materials shall be at the d scretion of the CalRecycle project engineer and/or his or her designee. It is recommended that all solid waste sites be surveyed for radioactive material especially E t illegal dumps. At a minimum, it is recommended that sampling team implement the f)llowing: 1. Don personal radiation monitoring devices (radiation dosimeter); 2. Perform a general survey of the waste area(s) using an instrument capable of detecting alpha, beta, and gamma radiation;. 3. Spot survey the sampling locations; Lodi City Landfill 32 January 2012 Site Safety and Health Plan
