This standard method describes procedures for measuring the chemical emissions of semi-volatile and volatile organic compounds (SVOCs and VOCs) from spray polyurethane foam (SPF) insulation samples in a spray booth. The method can be used to evaluate emissions during the spray operation as well as from post sprayed SPF insulation. Specific compounds of interest may include isocyanates, blowing agents, amine catalysts, flame retardants, aldehydes, etc. This method describes the specifications of the spray booth and spraying equipment, volume and area of SPF material sprayed (loading factor), sample collection times, operating parameters (e.g. temperature, RH, ventilation rates, etc.) and how to collect emission samples from the spray booth for analysis using appropriate analytical test methods (e.g. thermal desorption tubes, silica gel with DNPH, isocyanate samplers, etc.). Data are expressed as mass of each target compound per volume of air collected (e.g. ug/m3), which can be compared to exposure limits, when available.
The data are useful to identify potential worker exposures and to evaluate re-entry times for trade workers and re-occupancy times for building occupants.
