_ XXXlene <br /> Hazards: Xylene is a skin irritant. Inhalation may result in headache, <br /> dizziness, and Irritation to the eyes, nose, or throat. Continued exposures <br /> to high concentrations may result in dizziness and incoordination. <br /> • TLV: 100 ppm <br /> • Vapor Pressure: 5.72 mm at 21' Centigrade. <br /> - These chemical compounds are both skin contact and inhalation hazards. <br /> Consequently, protection from both skin contact and inhalation of hazardous <br /> chemicals must be sddressed by the Health and Safety Plan for this site. <br /> 4.1.2 Hazards Associated with Work Activities <br /> The site investigation consists of work taxs that will be conducted on- <br /> site. This section of the Health and Safety Plan briefly describes each work <br /> o task and the potential chemical and physical hazards posed to workers by each <br /> task. Sections 1.2 through 1.11 of this Plan describe the standards and <br /> r� procedures that will be implemented to mitigate tiese hazards. <br /> 7 <br /> 1. Monitoring well installation. One groundwater monitoring well will <br /> nstalled lasing a hollow stem auger. The purpose of the well will <br /> be to establish the level, if any, of contamination in the <br /> P - groundwater. <br /> Hazards: Worker exposure to the identified chemicals could occur due <br /> to inhalation of these compounds, inhalation of contaminated dust, or <br /> skin contact with contaminated soil or water. <br /> Drilling rigs may create hazards due to falling objects, swinging <br /> r <br /> "". objects and/or lines; rigs will travel or back near workers perform- <br /> ing related work task; and noise exposures may be generated by <br /> k hammering activities, and from equipment engines. <br /> 2. Soil and groundwater sampling. Soil samples will be collected from <br /> borings, and groundwater samples from developed wells. <br /> Hazards: Worker exposure to the identified chemicals could occur due;., <br /> is tc+ inhalation of these compounds, inhalation of contaminated dust,,'or, <br /> skin contact with contaminated soil or water. <br /> — — — --- . - - --4�2--ASSIGNMENT-OF-RESPONSIBILITIES----------------- -- --- — - --- ----- -- <br /> All personnel involved in operations who treat, excavate, trench, handle, <br /> E sample, dispose of, or otherwise have a potential for exposure to site- <br /> specific contaminated materials are subject to this H&S Plan. <br /> LL; <br /> 0-3 <br /> k:ENG:9204-AppD/031191 <br />
