LAUSD Proposed South Region High School #9 & Middle School #4 12.0 SITE CONTROL MEASURES 12-1 December 2006 Site Specific Health & Safety Plan (HASP) The following site control measures will be followed to minimize potential contamination of workers, protect the public from potential site hazards, and control access to the sites. Site control involves the physical arrangement and control of the operation zones and the methods for removing COCs from workers and equipment. The first aspect, site organization, is discussed in this section. The second aspect, decontamination, is considered in the next section. Site access will be coordinated with the LAUSD security located at the site. 12.1 SITE ORGANIZATION-OPERATION ZONES The following organization-operation zones will be established on the site or around a particular site feature, as needed. • Exclusion Zone (Contamination Zone), • Contamination Reduction Zone, and • Support Zone. The Field Team Manager and/or SHSO will be responsible for establishing the size and distance between zones at the site or around the site feature, based on identified contamination. Considerable judgment is required to ensure that safe working distances for each zone are balanced against practical work considerations. Exhibit 12-1 shows the site control for a typical hazardous waste site. 12.1.1 Exclusion Zone The exclusion zone includes the areas of drilling, excavation, hazardous waste removal, and other remedial activities. Within the exclusion zone, prescribed levels of PPE must be worn by all personnel. The hotline, or exclusion zone boundary, is initially established based upon the presence of actual wastes or apparent spilled material, or through air monitoring, and is placed around all physical indicators of hazardous substances. The hotline generally consists of an easily identifiable physical boundary (e.g., bright orange or yellow flagging attached to stakes), and may be readjusted based upon subsequent observations and measurements. This boundary will be physically secured and posted or well-defined by physical and geographic boundaries, such as: • Red tape/flagging indicates Danger/Hot Zone/Stay Out/Specifically trained and authorized persons only. • Yellow tape/flagging indicates Caution/Warm Zone/ Proceed with caution. Under some circumstances, the exclusion zone may be subdivided into zones based upon environmental measurements or expected on site work conditions. 12.1.2 Contamination Reduction Zone If decontamination is required, a contamination reduction zone will be established between the exclusion zone and the support zone. This zone provides an area to prevent or reduce the transfer of hazardous materials that may have been picked up by personnel or equipment leaving the exclusion area. All decontamination activities occur in this area. The organization of the 237
LAUSD Proposed South Region High School #9 & Middle School #4 12-2 December 2006 Site Specific Health & Safety Plan (HASP) contamination reduction zone, and the control of decontamination operations, are described in Section 13. 12.1.3 Support Zone The support zone is the outermost area of the site and is considered a non-contaminated or clean area. The support zone contains the command post for field operations, first-aid stations, and other investigation and cleanup support. Normal work clothes are appropriate apparel within this zone. Potentially contaminated personnel, clothing or equipment are not permitted. 12.2 SITE SECURITY Site security for investigation and remedial activities is necessary to prevent exposure of unauthorized, unprotected individuals in the work area. No unauthorized personnel shall be allowed within the fenced perimeter of the Site. Site access will be coordinated with the LAUSD security at the Site. Site security for specific tasks will be enforced by the SHSO or a designated alternate who will ensure that only authorized personnel are allowed in the work area and that entry personnel have the required level of PPE, are trained under the requirements of Title 8 CCR 5192, and are on a current medical monitoring program. General site security also is necessary to protect site workers and LAUSD property from individuals who approach the site with intent to cause harm or damage. In the event that individuals approach the site with intent to cause harm or damage, handheld radios will be used to communicate the potential danger between the LAUSD security command post at the site and on-site workers. The LAUSD security personnel will contact the local police department, if necessary. On-site workers will take refuge in their work vehicle. 12.3 SITE COMMUNICATION Internal site communication is necessary to alert field team members in the exclusion and contamination reduction zones to: • Emergency conditions; • Convey safety information; and • Communicate changes or clarification in the work to be performed. For internal site communication, the field team members will use prearranged hand signals (and responses). Radios may also be used for communication in the event of an emergency to alert employees. Site alarms include: One horn blast = look this way; pay attention Three horn blasts, repeated = local evacuation, gather at field office for further instructions Five horn blasts, repeated = general site evacuation, gather off-site (north of site on Adella) External site communication is necessary to coordinate emergency response teams and to maintain contact with essential offsite personnel. A telephone located at the LAUSD security guard station will be available for use for external site communication. In the event that the land 238
