Health and Safety Plan 705 Carlton Avenue, Stockton, CA EFI Global Project No. 9836003958 Delineation of these zones will be based on sam piing and monitoring results, an evaluation of potential exposure rou tes, and an estimate of the potenti al for contaminant dispersion in case of a release. Movement of workers and equipment am ong these zones should be minimized and restricted to preven t cross-contamination from contaminated areas to clean areas. 9.1 EXCLUSION ZONE The Exclusion Zone (EZ) is the area where hazardous substances are known or suspect ed to be present and pose the greatest potential for exposure. The EZ will be established before the start o f work by t he placement of cones, delineators, caution tape, signs, or other physical barrier s as needed to control acce ss and prevent entry b y una uthorized personnel. Work ers within the EZ shall h ave or be acco mpanied by personnel having a m inimum of 40 hours of off-site instru ction (or its equivalent) and three day s of actual field experience under the supervision of a trained, e xperienced supervisor. In addition, t hey shall have annual 8-hour refresher training as required by 29 CFR-1910.120. Supervisors and managers engaged in this hazardous waste operati on shall have received the equivalent training to the workers they supervise plus an add itional 8 h ours of specialized training as required by 29CFR-1910.120. Geologists or Engineers engaged in preliminary inv estigatory or site asses sment activit y in which the potential for exposure to hazardous substances is li mited, shall have a minimum of 40 hours of hazardous waste operations training and an additional three day s of actual field experience under the direction of an experienced, trained supervisor. Access control poi nts will be established at the pen i phery of the EZ to contr ol the flow of personnel a nd equipment into and out of the zone and to help veri fy that pro per procedures for entering and exiting are followed. If feasible, separate entrances and ex its should be established to separate personnel a nd equipment movement into and out oft he zone. Pers onnel working in the EZ will be required to wear the level of PPE specified in this HASP. 9.2 CONTAMINATION REDUCTION ZONE The Contamination Reduction Zone (CRZ) is the tr ansition area between the EZ and the clean area. It is designed to reduce the probabilit y that the clean Support Zone will beco me contaminated or affected by other site hazards. The distance between the EZ and the Support Zone provided by the CRZ, together with the decontamination of w orkers and equipm ent, limits the physical transf er of hazardous substances into clean are as. The degree of conta mination in the CRZ decreases as one moves from the EZ to the Support Zone, due to both the distance and the decontamination procedures. Decontamination procedures take pla ce in a desi gnated area of the CRZ called the Contam ination Reduction Corridor (CRC). The CRC begins at the outer edge of the EZ, called the Hotline, and extends to the Contamination Control Line, which is th e boun dary between the CRZ and the Support Z one. Access into and out oft he CRC is thr ough Access Control Points. Personnel entering the CRC fro m the Support Zone are required to wear the PPE pros cribed for working withi n the CRZ. To reenter the Support Z one, workers should rem ove any PPE and e quipment within the CRZ, and leave through the Access Control Point. Support staff will be stationed in t he CRZ as appropr iate, and Personnel and E quipment Decontamination Stations will be established within the CRC. Th e CRZ will be designed to facilitat e decontam ination of workers and equipment; first aid and emergency response; sample handling; equipment supply, including PPE and tools; and handling of decontamination waste. A worker rest area will also be established within the CRZ. EFI Global Page 7 of 19
