Tetraethyl lead 0.075 <br />mg /m3 <br />1,2-Dichloroethane 1.0 1.0 2.0 <br />(Ethylene <br />dichloride) <br />Note: *Values specified by ACGIH <br />For purposes of health and safety the strictest <br />established exposure limit shall be used. <br />Physical and chemical hazards must be monitored onsite <br />to ensure that workers are not exposed to hazardous <br />situations. The monitoring which shall be performed <br />during this project is described below. <br />FMIJ PA"!W"W <br />Exposure to excessive heat, noise, and hazardous work <br />conditions shall be monitored throughout the project. <br />All workers entering areas where two people cannot <br />carry -on a normal conversation will be required to wea <br />hearing protection. If heat stress is anticipated due <br />to hot weather or the use of PPE, workers will be <br />monitored by the SSP and will be provided beverages, <br />shaded rest areas, and breaks to prevent heat stress. <br />200 <br />Work area safety inspections will be conducted daily <br />before the start of work and as conditions change by the <br />SSO. Hazardous conditions reported to or observed by <br />the SSO shall be immediately corrected. <br />5.2 E2W _Os u <br />The fire, explosive, and toxic inhalation hazards <br />previously mentioned will be evaluated throughout the <br />project. <br />A direct -reading combustible gas/oxygen meter (CGI) will <br />be used to evaluate the possible formation of flammable <br />atmospheres around the work area. Continuous <br />flammability measurements will be taken at the top of <br />the boring near the work crew throughout well <br />installation. Periodic measurements will be obtained <br />frc;m soil piles, within excavations, and in confined <br />areas where flammable/combustible vapors may accumulate. <br />0 <br />
