Ethyl Benzene <br /> Hazards Ethylbenzene is a skm untant Inhalation may result in headache, dizziness, and <br /> irritation to the nose and throat Continued exposure to high concentrations may <br /> result in mcoordmation, loss of consciousness, or respiratory failure <br /> • TLV 100 ppm <br /> • Vapor Pressure 10 mm at 25 9° C <br /> Xylene <br /> Hazards Xylene is a skin irritant Inhalation may result in headache, dizziness, and irritation <br /> to the eyes, nose, or throat. Continued exposures to high concentrations may result <br /> in dizziness and incoordination <br /> • TLV. 100 ppm <br /> • Vapor Pressure b 72 mm at 21° C <br /> These chemical compounds are both skin contact and inhalation hazards Consequently, <br /> protection from both skin contact and inhalation of hazardous chemicals must be addressed by <br /> the Health and Safety Plan for thus site. <br /> 3.1.1 Hazards Associated with Work Activities <br /> This section of the Health and Safety Plan briefly describes each work task and the potential <br /> chemical and physical hazards posed to workers by each task Sections 3 2 through 3 11 of <br /> this Plan describe the standards and procedures that will be implemented to mitigate these <br /> hazards. <br /> 1. Borehole drilling. Two boreholes will be installed using a hollow stem auger <br /> dnllmg ng The purpose of those boreholes will be to establish the vertical <br /> distribution of diesel fuel and its components beneath the former tank Iocation <br /> Hazards Worker exposure to the identified chemicals could occur due to <br /> inhalation of these compounds, inhalation of contaminated dust, or skin contact <br /> with contaminated groundwater <br /> Drilling rigs may create hazards due to falling objects, swinging objects and/or <br /> lines, rigs will travel or back near workers performing related work task; and <br /> noise exposures will be generated by hammering activities and from equipment <br /> engines <br /> MZ Z9-21-93/ENG/93-01271k <br /> 10 <br />
