Industrial Dust, Silica & Occupational Exposure Testing
Occupational exposure testing pairs analyte-specific sampling methods (OSHA and NIOSH) with laboratory analysis — respirable crystalline silica by X-ray diffraction or infrared methods, metals on filters, VOCs on sorbent tubes — plus combustible dust characterisation for process safety. Interpretation against exposure limits is the industrial hygienist's role.
What does it measure?
- Respirable crystalline silica in air samples
- Airborne metals and welding fume constituents
- Volatile organic compounds by sorbent tube methods
- Combustible dust properties (Kst, Pmax, minimum ignition energy)
When is it used?
- Exposure assessment and compliance monitoring programmes
- Evaluating controls after process changes
- Combustible dust hazard analysis
- Investigating worker complaints or regulatory inspections
Sample considerations
- Sampling media and flow rates are method-specific — agree the sampling plan before mobilising.
- State the jurisdiction and averaging period so results can be interpreted correctly.

Frequently asked questions
- Does the laboratory decide whether exposure is acceptable?
- The laboratory reports measured concentrations; a qualified industrial hygienist interprets them against the applicable occupational exposure limits and context.
