Monitoring Methods used by OSHA
Laboratory Sampling/Analytical Method:
-
sampling media: Mixed Cellulose Ester Filter (MCEF) 0.8 microns
maximum volume: 960 Liters minimum volume: 480 Liters maximum flow rate: 2.0 L/min
current analytical method: Atomic Absorption Spectroscopy; AAS/GF
method reference: OSHA Manual of Analytical Methods (OSHA ID-105)
method classification: Fully Validated
NOTE: If the filter is not overloaded, samples may be collected up to an 8-hour period.
For volatile arsenic compounds, sample with a MCEF 0.8 microns filter followed by a sodium carbonate treated backup pad.
Arsenic and any of the following metals may be analyzed from the same full-shift sample: lead, cadmium, iron, zinc, and copper.
If arsine is suspected to also be present, sample with a MCEF and a sodium carbonate treated backup pad followed by and in series with a large charcoal tube containing 400 mg (front) and 200 mg (backup) sections of activated coconut shell charcoal. This sampling train is described in Section 5.1.2. of OSHA ID-105. The minimum air volume is 120 L and the sampling rate is 0.5 L/min with this sampling train.
Wipe Sampling Method:
-
sampling media: Whatman Smear Tab Filter.
analytical solvent: Distilled water
