<br /> B. JOB and RISK ANALYSIS
<br /> Residual levels of VOC's motor fuels in the tank,soil and groundwater may create a potential explosion,fire or
<br /> exposure hazards. Exposure by vapors is the likely hazard for this project.
<br /> Confined space entry will not be performed.
<br /> Power machinery, including drilling rigs, excavation equipment, and concrete cutting equipment will be used
<br /> on the site. Sub-contractors will be requested to site their equipment in a safe manner; the site safety officer
<br /> will have the final approval for site set-up.
<br /> Chemical Hazards-Possible Compounds Encountered May Include--
<br /> Petroleum Fuels and Related Compounds
<br /> Gasoline Fuel - CAS:8006-61-9 A mixture of volatile hydrocarbons suitable for use in spark ignition internal
<br /> _ combustion engines. It is highly flammable,with dangerous fire and explosion risk,TLV 300 ppm.
<br /> Diesel Fuel-(Fuel oil No. 2)-Fuel for diesel engines,a petroleum distillate,with volatility similar to gasoline.
<br /> Flash point 110-190 F_,d<1,combustible,flammable and explosion risk.
<br /> Benzene-CAS: 7143-2 -Component of gasoline and diesel fuels,F. P. 12_F, LEL 1.3%,Vapor Pressure 75
<br /> nun, Class 1B Flammable Liquid, known carcinogen, toxic by ingestion, inhalation and skin absorption,
<br /> Exposure Limits NIOSH Ca 0.1 ppm,IDLH 3,000 ppm.
<br /> Toluene - CAS: 108-88-3 - Component of gasoline and diesel fuels, F. P. 40 J, LEL 1.2%, Vapor Pressure
<br /> 65_F, Class 113 Flammable Liquid, toxic by ingestion, inhalation and skin absorption, Exposure Limits
<br /> '— NIOSH/OSHA 100 ppm,IDLH 2000 ppm.
<br /> Ethylbenzene-Component of gasoline and diesel fuels, F. P. 55_F, LEL 1.0%, Class 113 Flammable Liquid,
<br /> toxic by ingestion,inhalation and skin absorption,Exposure Limits NIOSH/OSHA 100 ppm,IDLH 2000 ppm.
<br /> Xylene - CAS: 1330-20-7 - Component of gasoline and diesel fuels, toxic by ingestion, inhalation and skin
<br /> absorption, F. P. 63/84/81_ F, LEL 1.0%, Vapor Pressure 7/9/9mm, Class 113 Flammable Liquid, Class 1C
<br /> Flammable Liquid,Exposure Limits NIOSH/OSHA 100 ppm,IDLH 1000 ppm.
<br /> Physical Hazards and Other Hazards
<br /> Physical hazards associated with this project are moving equipment,working near excavation equipment,noise
<br /> (in local proximity of machines).
<br /> Asbestos
<br /> This specific site health and safety plan anticipates Level D working conditions. Should asbestos containing
<br /> building materials be encountered,LA&S shall do the following: if the material is friable it shall not be
<br /> disturbed,and creation of fugitive dust will be minimized. The site will be secured and an AHERA certified
<br /> asbestos professional will be brought to the site to assess the existing conditions and to determine what
<br /> _ appropriate abatement measures should be recommended.
