Carbon Monoxide Indoor Contamination in an Apartment in San Francisco, CA


This involved a legal case regarding claims of carbon monoxide (CO) contamination and consequent adverse health effects for the renter of an apartment in San Francisco, CA, as a consequence of exposure to CO poisoning from a defective wall furnace.

EnviroComp's Role

We were retained by the plaintiff's attorney to evaluate the claims and perform indoor modeling of CO exposure. Our work included review of documents and reports; inspection of the apartment and measurements of dimensions and ventilation feature; design and implementation of an indoor tracer experiment using SF6 tracer; and calculation of CO emission rate from the furnace; calculation of CO concentrations inside the apartment under different residential scenarios using an indoor box model.
