<br /> 4.1 SITE WORK ZONES
<br /> To reduce the speed of hazardous Materials by workers, from the
<br /> contaminated areas to the clean areas, zones will be delineated at
<br /> the UST facility. The flow of personnel between the zones should
<br /> be controlled. The establishment of e w kswill help
<br /> the hazards
<br /> ensure that: personnel are properly p against
<br /> present where they are working; work activities and contaminations
<br /> are confined to the appropriate areas; and, personnel can be
<br /> located and evacuated in an emergency.
<br /> 4.1.1 Exclusion Zane
<br /> Exclusion zones will be established at the UST facility for all
<br /> drilling activities; unprotected onlookers should be located 50

<br /> 4.1.3 Support Zone
<br /> The support zone will include the remaining areas of the job
<br /> site. Break areas, operational direction and support facilities
<br /> (to include supplies, equipment storage and maintenance areas) will
