Monitoring
PRIMARY SAMPLING/ANALYTICAL METHOD (SLC1):
MEDIA:
Tared Low Ash Polyvinyl Chloride (LAPVC) filter 5 microns preceded by 10 mm nylon cyclone
MAX V:
816 Liters MAX F:
1.7 L/min
ANL 1:
Gravimetric analysis followed by X-ray Diffraction
REF:
11, 12, 2 (OSHA ID-142)
CLASS:
Fully Validated
NOTE:
Gravimetric analysis is field method for determining compliance with respirable Portland Cement standard. Following this analysis, submit sample to SLTC for X-ray diffraction analysis of respirable Quartz. Compliance can then be determined for both standards. If filter is not overloaded, samples may be collected up to an 8-hour period. Submit bulk sample in separate mailing container at time air samples are submitted.
