' 0 0 <br />' t. Total Organic Vapors <br />The direct -reading photoionization detector (Thermo -Environmental Model 580A or <br />equivalent) will be used to monitor the concentrations of organic vapors in the work area. <br />Organic vapors will be monitored periodically during the collection of soil samples. The <br />' meter will be calibrated at the start of each work period with isobutylene gas. Total <br />organic vapor measurements will be used to determine the appropriate levels of <br />respiratory protection, and identify conditions that would require site evacuation. Total <br />torganic concentrations in the worker's breathing zone in excess of 50 PPM will require <br />Level C personal protective equipment. Total organic concentrations in the worker's <br />' breathing zone in excess of 200 PPM will require evacuation of the work area until the <br />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 <br />' any health and safety related items which are unique or specifically germane to the project. <br />This will at least include the following: <br />' t. Summarize the physical and chemical health and safety hazards which can be <br />expected at the site. <br />' 2. 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, <br />procedures to be followed in the event of a chemical spill, fire, or explosion, <br />evacuation routes, mustering areas, etc.). <br />1 <br />11 <br />cca09-23.92/8787a.51/cp31 A-6 <br />
