Dust and particles
Real-time measurements reveal changes over time. Characterizing a dust fraction or identifying silica and certain metals may require sampling and laboratory analysis.
- Real-time particle trends
- Inhalable or respirable fractions, as specified by the protocol
- Crystalline silica and metals through appropriate sampling and analysis
Gases and vapours
Instrumentation must suit the substances, concentration range and possible interferences. No single detector or filter medium addresses every contaminant.
- CO, CO₂, NO, NO₂ and SO₂ as required
- VOCs, ozone and formaldehyde
- Mercury, oxygen and combustible atmospheres, subject to the assessment and available methods
Cab operating parameters
Differential pressure, airflow, air velocity, temperature and humidity help explain results. Leakage investigation and inspection of hard-to-reach areas complete the assessment.
A defined protocol, then conclusions
Specialized instruments and analyses are selected for the assignment. Samples can be sent to a qualified laboratory. The report documents methods, conditions and limitations.
A particle reading does not directly measure silica content. A CO₂ reading does not measure every hazardous gas.
