Incomplete combustion happens when there is insufficient oxygen; the inputs are fuels containing numerous contaminants and the outputs are damaging byproducts, most precariously carbon monoxide, which is an unappetizing and odor free gas with serious unfavorable health results. Without correct ventilation, carbon monoxide can be deadly at concentrations of 1000 ppm (0. 1%). Nevertheless, at numerous hundred ppm, carbon monoxide gas direct exposure causes headaches, fatigue, nausea, and vomiting. Carbon monoxide binds with hemoglobin in the blood, forming carboxyhemoglobin, reducing the blood's capability to transport oxygen. The primary health issues related to carbon monoxide gas direct exposure are its cardiovascular and neurobehavioral results. Carbon monoxide gas can trigger atherosclerosis (the hardening of arteries) and can also set off heart attacks.
