<br /> o Level A:Fully encapsulating suit,self-contained breathing apparatus(SCBA);Level A prohibited for Geosyntec personnel.
<br /> ® FOR SITE WITH CHEMICAL CONTAMINANTS OR WASTE BUT NOT REGULATED BY HAZWOPER
<br /> - Workers shall be knowledgeable/aware of chemical hazards thru safety training/orientation and availability of hazard information.
<br /> - Implement controls to minimize worker exposure through engineering controls,work practices,PPE,decon,as appropriate.
<br /> - Evaluate worker exposure via air monitoring/sampling,as applicable;see Part E,"Air Monitoring,Worker Exposure Monitoring."
<br /> ; STORAGE/TRANSPORT OF IDW* ❑Describe site-specific procedures above for spill containment,container handling,as applicable.
<br /> Spill/Release Risk: ❑For liquids,provide secondary containment during storage.
<br /> ❑Risk of incidental spill/release ❑Segregate incompatible chemicals during storage.
<br /> ❑Risk of emergency spill/release i ❑Locate emergency gear(eyewash,fire extinguisher,spill kit,safety signage)near storage area,as applicable.
<br /> ❑For incidental spills;spill kit on-site for low-hazard releases(low-flammability/toxicity/quantity/volatility)

<br /> Site-Specific Notes, Claditcations: Volatile Organic Compounds:Air monitoring of worker breathing zone will be performed by Geosyntec personnel while(1)
<br /> borings are being advanced,(ii)new monitoring wells are being installed into auger casings,(iii)when grouting to surface,and(iv)when developing new monitoring wells.
<br /> A photoionization detector with 11.7 eV lamp, properly calibrated in accordance with manufacturers instructions,will be used for monitoring of volatile organic
<br /> compounds(VOCs)in the worker breathing zone during these activities.Worker breathing zone readings will be recorded on no less than a 15-minute frequency.
<br /> Background readings will also be recorded and any sustained(longer than 5 seconds)detection above background levels will result in work stoppage so that engineering
<br /> controls can be instituted;this will consist of electrically powered fansforthe displacement of VOCsfrom the breathing zone.If sustained(longer than 5 seconds)detections
<br /> above background level are still detected after engineering controls are in place then work shall stop and either additional engineering controls shall be put in use before
<br /> resuming work activities or the boring will be terminated.
<br /> The primary VOC compound of concern is 1,2-dichloropropane(propylene dichloride)which has an OSHA PEL(8-hr TWA)of 75 ppm and a NIOSH IDLH of 400 ppm.
