l <br /> l <br /> SITE SECURITY <br /> Access during all on-site activities will be restricted to authorized personnel. All personnel and authorized <br /> visitors must contact the Site Safety Officer/Project Manager prior to entering and exiting the exclusion <br /> zone. <br /> RECORD KEEPING <br /> All site safety records pertaining to this site investigation will be maintained by the Site Safety <br /> Officer/Project Manager throughout the project. <br /> AIR MONITORING <br /> The Site Safety Officer/Project Manager(or another qualified person designated by the Site Safety Officer) <br /> wi11 conduct periodic air monitoring, using direct-reading, real-time sampling equipment. This will include <br /> using a direct-reading photoionization detector (Thermo-Environmental Model 580A or equivalent)to <br /> monitor the concentrations of organic vapors in the work area. Organic vapors will be monitored <br /> periodically during the collection of soil samples. The meter will be calibrated at the start of each work <br /> period with isobutylene gas. Total organic vapor measurements will be used to determine the appropriate <br /> levels of respiratory protection, and identify conditions that would require site evacuation. Total organic <br /> concentrations in the worker's breathing zone in excess of 50 PPM will require Level C personal protective <br /> equipment. Total organic concentrations in the worker's breathing zone in excess of 200 PPM will require <br /> evacuation of the work area until the organic concentrations subside to below 200 PPM. <br /> ADDITIONAL TRAINING AND INFORMATION <br /> Prior to any on-site activities, the Site Safety Officer/Project Manager will conduct training on any health <br /> and safety related items which are unique or specifically germane to the project. This will at least include <br /> the following: <br /> 1. Summarize the physical and chenucal health and safety hazards which can be expected at the <br /> site. <br /> J2. Personal protective equipment rationale, use, and maintenance. <br /> 3. Exclusion zone entry, exit, and decontamination procedures. <br /> 4. Emergency response procedures (i.e., emergency phone numbers, hospital route, procedures <br /> to be followed in the event of a chemical spill, fire, or explosion, evacuation routes, mustering <br /> areas, etc.). <br /> J <br /> Jcca/03/10/95 08:19 AM(0688brpt.doc/ntw12) A-6 <br />
