• • Project No. 014-95262 <br /> Page No. 6 <br /> 2.3 Noise <br /> While working around drilling equipment the potential exists for exposure to excessive noise. If <br /> noise levels are known/believed to exceed 85 dBA-8 hours per day, all individuals will be instructed to use <br /> adequate hearing protectors (ear plugs). Random monitoring using a noise dosimeter will be used to <br /> document noise levels. All field team members will be given background and annual evaluations. All field <br /> team members have been/will be trained in noise hazards and how to wear the protective equipment. <br /> 2.4 Sampling for Chemical Analysis <br /> Samples will be collected for the purpose of observation and soil logging. Additionally, selected <br /> samples may be submitted for chemical analysis. Some of these samples may contain high levels of <br /> hazardous materials creating the potential for chemical inhalation exposure, skin contact and possibly even <br /> ingestion. These activities may pose one of the greatest risks of chemical exposure for the site assessment <br /> work plan. Appropriate worker training, protective measures and medical monitoring will be enforced to <br /> control this health hazard potential. <br /> 2.5 Packaging and Shipment of Samples <br /> After the samples have been collected in sample containers, they will be properly packaged to <br /> protect shipping personnel. The hazards associated with shipping samples are minimal, provided care is <br /> taken to prevent the containers from leaking or breaking. Additionally, sample containers will be plainly <br /> marked in case of exposure. <br /> r <br /> 2.6 Sample Preparation and Analysis <br /> The preparation of samples for analysis may expose the technician to routine hazards associated <br /> with laboratory work. Standard laboratory safety procedures should be used to prepare and analyze these <br /> 1 samples. The samples should be treated carefully and handled inside a properly operating fume hood due <br /> to their potentially volatile and hazardous nature. In the event of a mishap, the laboratory supervisor <br /> should be notified immediately. <br /> r <br /> r <br /> KRAZAN&ASSOCIATES, INC. <br /> Offices Serving the Western United States <br /> 95261.HSP <br />
