Site Health and Safety Plan 19133 East Liberty Road, Clements, California August 16, 2022 Page 25 Sharp Environmental Technologies, Inc. For areas where chemical hazards are suspected, the first person entering the work zone will carry the appropriate instrument and monitor concentration levels in the work area before anyone else is allowed into the work zone. Thereafter, periodic and ongoing air monitoring will be conducted during the following site operations in the work zone and for personnel likely to have the highest exposures to the COCs: drilling and sampling. 6.3.1 Petroleum Vapors Associated with Gasoline The table below summarizes the various hydrocarbon vapor criteria and appropriate responses to potential vapor hazards. There are certain components, such as benzene vapors, that present significant hazards and must be properly controlled. Criteria for the use of respiratory protection are based on preventing potential exposures to benzene. 6.3.2 Hydrocarbon Vapor Criteria and Response Total Hydrocarbon Concentrations above Background Levels (parts per million by volume [ppmv] as measured by PID) Response <30 ppmv total hydrocarbon concentration (THC), verify that benzene concentration is below 1 ppm Limited hazard, no special action. 30–100 ppmv THC for more than two minutes in general work area Stop work, move upwind, monitor perimeter or don level C (half-face organic vapor respirator with P- 100 filter) and continue work or wait until levels decrease. 100–900 ppmv THC in general work area Wear full-face organic vapor respirators with P-100 filter in work area. >900 ppmv THC in general work area Stop work; procedures must be implemented to subdue excessive vapor levels. 7.
