RV Circuits <br /> Page 2 <br /> 9. No decision-making criteria are presented for selecting additional soil samples for <br /> analysis, nor for when samples that are analyzed for total metals may be analyzed for <br /> soluble concentrations. In addition, the analytical methods for additional procedures, must <br /> be specified, e.g., for soluble analysis. <br /> 10. The first column of"TABLE 2 REGULATORY GUIDELINES FOR VARIOUS <br /> METALS" should be labeled "Regulatory Guideline" or"Regulatory Standard." <br /> Health and Safely Plan Comments <br /> 11. The health and safety plan, in general, is inadequate. For example, it lacks any <br /> recognizable criteria for monitoring the potential hazards at the site. Examples include no <br /> heat stress monitoring protocol, and no discussion of how personal protection level <br /> upgrades and downgrades will occur. The entire plan should be reviewed and revised by <br /> an industrial hygienist with experience in hazardous substances investigations. <br /> 12. The "HAZARD EVALUATION" section of the health and safety plan should be revised <br /> to include a discussion of occupational exposure levels in relation to contamination levels <br /> known or suspected to be found at the site. <br /> 13. The health and safety plan should be revised to include a discussion about the <br /> decision-making protocols that will be used to upgrade or downgrade personal protection <br /> levels. Simply saying that it is the decision of the health and safety officer is inadequate. <br /> Each level of protection should be defined and the criteria for when that level of <br /> protection will be used based on health and safety monitoring for each hazard must be <br /> included. <br /> 14. The table discussing "Exposure systems" is incomplete. For example, the information <br /> presented about dust does not address the fact that the dust may contain toxic metals. <br /> Also, the plan lacks any criteria for deciding how dust will be measured/monitored in <br /> terms of what levels of personal protection will be used. Additionally, the plan lacks any <br /> information about adequate dust control procedures. <br /> 15. The table discussing"First aid" is also inadequate. For example, donning a respirator is <br /> not a means of first aid and would in fact result in greater pulmonary difficulty for <br /> someone who needs first aid due to a dust exposure. <br />
