SITE CONTROL <br />(in compliance with 29 CFR 1910.120(b)(4)(ii)(F) and 29 CFR 1910.120(d)) <br />This site control program is designed to reduce the spread of hazardous substances from <br />contaminated areas to clean areas, to identify and isolate contaminated areas of the site, to <br />facilitate emergency evacuation and medical care, to prevent unauthorized entry to the site, and <br />to deter vandalism and theft. <br />The site control program includes the elements specified in 29 CFR 1910.120(d) and provides <br />the following site-specific information: <br />a site map, indicating site perimeter and work zones <br />site access procedures <br />site security <br />site work zones including standard operating procedures <br />use of the buddy system <br />both internal (on-site) and external communications <br />is responsible for evaluating site conditions and for verifying that the site is <br />working in a safe manner. <br />Site Work Zones <br />This site is divided into three (3) major zones. These zones are characterized by presence or <br />absence of biological and chemical hazards and the activities performed within them. <br />Zone boundaries are clearly marked at all times and the flow of personnel and equipment among <br />the zones is controlled. <br />The site is monitored for changing conditions that may warrant adjustment of zone boundaries. <br />Zone boundaries are adjusted as necessary to protect personnel and clean areas. Whenever <br />boundaries are adjusted, zone markings are also changed and workers are immediately notified <br />of the change. <br />The following criteria were considered in establishing the site work zones: <br />required clean-up activities <br />sampling results for air and surface contaminants <br />inside traffic patterns <br />ventilation system & air circulation patterns <br />air dispersion calculations <br />potential for fire <br />physical, biological, other characteristics of anthrax spores and decontamination <br />substances <br />Exclusion Zone <br />The Exclusion Zone is the area where hazardous substances are known or suspected to be present <br />and pose the greatest potential for exposure. Remediation operations (site clean-up) are <br />r. John Winkler <br />3
