i' I The above levels of protection will be utilized during initial field operations. Upon receiving data from air, soil and water sampling, these levels of protection will be re-evaluated to provide sufficient employee protection I. -I while maximizing productivity. A situation may be present in which Level C respiratory protection is utilized while Level D clothing is used. Criteria for downgrading personnel protective equipment during field activities will be laboratory results indicating no potential for exposure above the Permissible Exposure Level (PEL) for any site contaminant. 90 SITE CONTROL � 1 9.1 SITE SECURITY No one will be allowed to enter a site work area unless they have been given permission to do so by the Project Manager and the Site Safety Officer, and otherwise follow applicable portions of this HASP. All work areas are secured with a chain linked fence which will be kept locked at all times. ,I 1 9.2 DECONTAMINATION PROCEDURES In order to assure that contamination is controlled and not spread from the site, decontamination procedures will be employed for both equipment and personnel. All decontamination activity will be monitored to assure compliance with the procedures described below. Decontamination of personnel and equipment will be required following the monitoring activities. Decontamination procedures will be developed for both equipment and personnel. A distinction will be made between personnel equipment and monitoring equipment for purposes of decontamination. ( i 9.2.1 STANDARD DECONTAMINATION L_ . All field personnel exiting from the site must pass through a personnel contamination reduction corridor (CRC). At a minimum, all personnel exiting the site will remove all protective clothing and wash their face and hands before entering lunch and break areas to eat, drink or smoke. All personnel will perform a field wash (as defined below) before leaving the site. All coveralls, gloves, and other protective wear will be containerized in 55- gallon drums. Decontamination of equipment will be performed with a triple rinse of Liquinox water, rinse water, and deionized water. A temporary CRC will be established by spreading a waterproof ground sheet and using several tubs for personnel decontamination. The area will be established by the SSO in discussion with the HSC and BEII Project JManager. r On-site showering will not be required as part of the routine decontamination procedure. However, a shower will be taken at the end of the working day after returning from the site to complete the decontamination process before the next meal or retiring for the day. Disposal equipment, including respirator cartridges, must be placed in heavy plastic bags or directly into ( 55-gallon drums for off-site disposal in an approved manner. Used decontamination solutions will also be stored in 55-gallon drums. 9.2.2 EMERGENCY DECONTAMINATION In the event that a seriously injured person is suspected of being contaminated, the SSO or other site worker will wrap the injured individual in clean plastic sheeting to prevent contamination of the ambulance. Less severely injured individuals will have their protective clothing carefully cut off before transport to the hospital. (
