4.0 WORK AND SUPPORT AREASTo prevent migration of contamination caused through tracking by personnel or equipment,work areas and personal protective equipment will be clearly specified prior to beginningoperations. OHM has designated work areas or zones as suggested by the MOSH/OSHA/USCG/EPA’S document titled, “Occupational Safety and Health Guidance Manual forHazardous Waste Site Activities.” Each work area will be divided into three zones as follows:lllAn Exclusion or “hot” Zone (EZ)A Contamination Reduction Zone (CRZ)A Support Zone (SZ)4.1 EXCLUSION ZONEThe EZ is the area suspected of contamination and presents the greatest potential for workerexposure. Personnel entering the area must wear the mandated level of protection for that area.In certain instances, different levels of protection will be required depending on the tasks andmonitoring performed within that zone. The exclusion zone will be clearly demarcated by theuse of fluorescent colored banner-guard and/or temporary fencing. Access to this area will becontrolled by physical barriers, and through monitoring activities conducted by the SSO.4.2 CONTAMINATION REDUCTION ZONEThe CRZ or transition zone will be established between the EZ and SZ. In this area, personnelwill begin the sequential decontamination process required to exit the EZ. To prevent off-sitemigration of contamination and for personnel accountability, all personnel will enter and exitthe EZ through the CRZ.4.3 SUPPORT ZONEThe SZ serves as a clean, control area. Operational support facilities are located within the SZ.Normal work clothing and support equipment are appropriate in this zone. Contaminatedequipment or clothing will not be allowed in the SZ. The support facilities should be locatedupwind of site activities. There will be a clearly marked controlled access point from the SZinto the CRZ and EZ that is monitored closely by the SSO and the SS to ensure proper safetyprotocols are followed.OHM Project 16487SSHSP Health and Safety Plan July 199sInformation herein is proprietary and confidential and to be used or rskased to othsn only with explicit writtcp permission of OHM RancdiationSeticu Corp.4-l
