L.P.G. (Liquified petroleum gas)
Analysis:
Combustible gas and simple asphyxiant
Recommended method by the IRSST:
Method: MANUEL - ILD
Sampling protocol
Sampling device:
Parameters:
Flow rate: -
TWA sampling volume: -
STEL sampling volume: -
Remarks:
Since this contaminant is a simple asphyxiant, the field method for determination of oxygen in air is done with a direct reading instrument-Electrochemical sensor (DRI-elec). A combustible gas detector (DRI-EX) is used for analyzing flammables gases as a percentage of their lower explosive limit. Refer to the user's guide accompanying the instrument.
Analytical protocol
Principle:
Direct reading instrument-Combustible gas detector and electrochemical cell (ILD-EX/PEL)
Reference
Direct Reading Instrument (DRI). Consult the manufacturer's manual.
