Syr. 2005 <br />I 111 • • 0 • <br />An Equipment Decontamination Area must be established for each Exclusion Zone. It may be <br />part of the Exclusion Zone, outside of the zone, or both. Equipment, such as sampling <br />devices, which must be decontaminated before being reused in an Exclusion Zone, may be <br />decontaminated in the Exclusion Zone. Equipment, such as hand auger, will be <br />decontaminated in a relatively uncontaminated area in a Contamination Reduction Zone before <br />leaving the controlled area. Protective <br />equipment worn in Exclusion Zones must also be worn in equipment decontamination areas. <br />One or more areas shall be designated for decontamination of personnel. Because personal <br />decontamination will be required before rest breaks, lunch, leaving the site at the end of the <br />work shift, and entering the Support Zone to coordinate activities with other personnel. <br />. i' ' W491 <br />A Support Zone is a relatively clean area where support equipment and facilities are located. <br />The Support Zone is best if stationed upwind of the exclusion or disturbance area(s). <br />The level of protection while performing tasks at the site will be dependent upon known <br />and/or suspected contaminants to be encountered during the progress of the works. The level <br />of protection, and any upgrading or downgrading, will be determined by the SSHO. Generally, <br />tasks of subsurface investigations and site assessments in the area of UST's can be <br />accomplished at a D Level of protection. <br />The following list personal protective clothing and equipment for personnel while working at <br />Level D. <br />* Nomex Coveralls (mandatory when in exclusion zone) <br />* Work gloves <br />* Latex gloves for sampling personnel <br />* Construction Quality Boots <br />* Safety glasses <br />* Hard Hat <br />* Half or Full -face air -purifying respirators (optional) <br />* Hearing protection (optional) <br />11 <br />
