ii <br /> 3" Project No,034-98081 <br /> Page No. 6 <br /> I <br /> 2.3 Noise <br /> While working around drilling equipment the potential exists for exposure to excessive noise. If <br /> noise levels are knownibelieved to exceed 85 dBA-8 hours per day, all individuals will be instructed to use <br /> � 3ir <br /> { adequate hearing protectors (ear plugs). Ra' door monitoring using a noise dosimeter will be used to <br /> !� ii <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 Analis I <br /> I <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 /> T <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 /> I <br /> 2.5 Packaging and Shipment of Samples <br /> a <br /> 1 <br /> After the samples have been collected in sample containers,they will be properly packaged to protect <br /> if <br /> t shipping personnel. The hazards associated with shipping samples are minimal, provided care is taken to <br /> prevent the containers from leaking or breaking. Additionally, sample containers will be plainly marked in <br /> case of exposure. <br /> 9 1 <br /> 2.6 Sample Preparation and Analysis ! <br /> The preparation of samples for analysis may expose the technician to routine hazards associated with <br /> laboratory work. Standard laboratory safety procedures should be used to prepare and analyze these samples. <br /> The samples should be treated carefully and lhandled inside a piToperly operating fume hood due to their <br /> y ;i1` <br /> potentially volatile and hazardous nature. Iii the event of a mishap, the laboratory supervisor should be <br /> notified immediately. <br /> is <br /> 3.0 SAFE WORK PRACTICES AND LEVEL OF PERSONAL PROTECTION <br /> The following sections present procedures on how to adequately address the primary potential <br /> hazards encountered in the different task of this project. The standard level of personal protection is also <br /> LFdefined. <br /> KRAZAN & ASSOCIATES,INC. <br /> 4 Offices Serving the Western United States <br />
