ACIDS,CAUSTICS,OTHER ❑Use appropriate protection for eyes/face(goggles/face shield)and skin(gloves,sleeves,apron).
<br /> CORROSIVES ❑Use eyewash,deluge shower,drench hose,hand washing(with water),as appropriate.
<br /> ❑For severe eye hazards(due to high corrosivity,large quantity),15-min.eyewash required.
<br /> TOXIC ; ❑For toxic substances,use/store in a manner to control exposure hazards(inhalation,ingestion,skin contact,
<br /> i skin absorption);use active ventilation and/or PPE as appropriate.
<br /> ® ? EMISSIONS FROM FUEL ®Position outdoor personnel upwind of exhaust source.
<br /> i COMBUSTION,HOT PROCESSES ❑Avoid"idling"of equipment when not in use.
<br /> ®Gasoline ❑Use passive ventilation(air infiltration/air currents)to disperse atmospheric hazards in breathing zone.
<br /> ®Diesel i ®Use dilution ventilation(blowers/fans)to provide fresh air to work area and dissipate atmospheric hazards.
<br /> { ❑Propane/Natural Gas ❑Use exhaust ventilation(hood/dud/exhaust stack/blower)to capture/divert exhaust from work area.
<br /> ❑Welding/cutting/hot work I ❑Use respiratory protection for high levels of smoke,exhaust particulates,soot.

<br /> Site-Specific Notes&Clarifications: Site soil may be impacted by historical releases of nitrogen fertilizer and organic compounds,including carbamate/urea
<br /> compounds,organochlorine compounds,triazines,and chlorinated herbicides;earlier cleanup efforts were directed at remediation of this soil. The most recent
<br /> soil monitoring performed in 2007 indicated the following:(i)triazine compounds and chlorinated herbicides have not been detected in any soil sample since
<br /> 2005,(ii)organochlorine compounds DDT isomers and endrin have been found in the upper foot of soil at concentrations below site cleanup goals(1.0 mg/kg and
<br /> 0.5 mg/kg,respectively),and(III)carbamate compounds bromacil,diuron and tebuthiuron have been found in the upper three feet of soil at levels below cleanup
<br /> goals(0.9 mg/k&0.1 mg/kg and 4.9 mg/kg,respectively).
<br /> Groundwater monitoring results from MW-5B and M W-78 in 2023 indicated the following constituent concentrations:
<br /> o Nitrate as nitrogen:up to 360 mg/L;
<br /> 0 1,2-Dichloropropane:up to 460 µg/L;
<br /> 0 1,2,3-Trichloropropane:up to 0.93 µg/L;
<br /> o Carbamate herbicides:Bromacil up to 15 µg/L and Diuron up to 1.5 µg/L;and
<br /> o Triazine herbicides:Atrazine up to 0.18 pg/L.
