OSTI ID:6411237
;
This patent describes a method for testing a gas at a temperature below about -10 degrees F for the presence of a hazardous gas. The method consists of: (a) passing a quantity of the gas through a tubing positioned in a garment and near the inner surface of the garment so that body heat of a wearer of the garment is transferred to the gas flowing through the tubing to heat the quantity of gas with the body heat of the wearer of the garment; and (b) analyzing a portion of the heated quantity of gas for the presence of the hazardous gas.
