Permissible Exposure Limit (PEL) for an 8 hour exposure �toybenzene. <br />Action Levels of Hy.-rocarbon Components in Petroleum Fuel: <br />Gasoline <br />>300ppm <br />PEL LEL > 10% <br />Benzene <br />> 1ppm <br />PEL Oxygen <19.5% <br />Toluene <br />>100ppm <br />PEL <br />Xylene <br />>100ppm <br />PEL <br />Ethyl Benzene <br />>100ppm <br />PEL <br />A hydrocarbon vapor analyzer will be used to measure real time <br />breathing zone concentration for comparison with the 100 ppmv working <br />limit. When a persistent level of 100 ppmv is observed, appropriate <br />respirators will be donned and other vapor measurements will be made. <br />If hydrocarbon vapors exceed 1000 ppmv or 10 ppm benzene, work will <br />be stopped. The field crew will be instructed to stay up wind and <br />methods will be applied to subdue fugitive vapor emissions such as <br />sprinkling soil with water, or the use of copus blower. <br />The site Safety Officer will make such determinations. <br />If LEL is >10% in or around the tank, work must stop and not commence <br />until determined safe and/or LEL% <10%. <br />If oxygen levels in the immediate work area are < 19.5%, work must <br />stop until determinated safe and/or levels are >19.5%. <br />Symptoms Of Acute Overexposure: Gasoline and gasoline vapors maybe <br />irritating to the skin, eyes and respiratory tract. Gasoline vapors <br />may effect the central nervous system and may cause headaches and <br />dizziness. <br />Oxygen Deficiency: May cause dizziness. <br />SSP -5 <br />
