An onsite orientation session will be required for all onsite personnel and will include the following <br /> • Health effects and hazards of the chemicals identified or suspected onsite <br /> • Personal protection including use, care, and fitting of personnel protective equipment, and <br /> necessity for personal protection,its effectiveness,and limitations of the equipment <br /> • Decontamination procedures, <br /> • Any prohibitions in the areas and zones including site Iayout, and procedures for entry and exit <br /> of areas and zones, <br /> • Standard safe work practices,and <br /> • Emergency procedures, including emergency contacts, instructions for implementing the <br /> emergency plan,and location of emergency equipment <br /> AIR MONITORING `11vv <br /> Personal air monitoring is not anticipated at this time Potentially contaminated soils excavated are 55 <br /> unlikely to produce conditions requiring respiratory protection The foreman and/or industrial <br /> hygienist will continually evaluate the drilling operations to determine the presence or absence of <br /> petroleum hydrocarbon odors Decisions concerning respirator use will be influenced by visual <br /> -� )observations of the workers,and the duration and intensity of hydrocarbon odors If hydrocarbon <br /> odors are detected for more than 10 to 15 minutes, or if intense hydrocarbon odors are detectedS 1 �S baJ. i <br /> any point, it is recommended that both atmospheric and personal air monitoring be performed <br /> Onsite air monitoring with an Organic Vapor Analyzer (OVA) and colorimetric indicator tubes will w <br /> not be needed unless persistent odors are encountered Should the OVA detect a level greater than <br /> 100 ppm eV,or should colorimetric indicator tube analysis detect benzene at a level greater than 1 <br /> ppm, level C respiratory protection will be instituted until the vapors have been dissipated The <br /> Permissible Exposure Limit (PEL) for gasoline is 300 ppm, the PEL for toluene is 100 ppm, the <br /> PEL for Xylene is 100 ppm, and the PEL for benzene is 5 ppm <br /> The need for respiratory protection is not anticipated <br /> Health and Safety Plan for F&H Construction <br /> 130 North Hunter St, Stockton, CA <br /> Pa- 1 <br />
