Combustion By-Products
Purpose of Test
This test is designed for analysis of fire residues for presence of analytes of interest (char, black carbon/soot and ash). The results of this test offer the client valuable information related to the extent of damage produced by a fire at a location (residential, industrial or wildfires). These results can be used for cleaning assessment and/or insurance claims.
Sampling
Surface Sampling:
- Alcohol prep wipes (recommended surfaces: TV’s computer displays, plastic surfaces, furniture, windows, mirrors, internal surfaces of refrigerators; avoid painted surfaces)
- Microvacuum: 25 mm 0. 45 micron or 0.8 microns pore size MCE cassettes (recommended surfaces: main living areas, from top of interior door frame, window frame, from corners of floors, door tracks, attic areas)
- Tape lifts (recommended surfaces- same as for alcohol prep wipes)*
Air sampling:
- PVC pre-weighed cassettes (for NIOSH 5000 only)
- Zefon CSI cassettes*
- Zefon Air-o-cells*
- 25 mm 0.45 micron pore size MCE cassettes; Flow rate 0.5-16 L/min, Min volume 400*
