Of all the vapors tested, a small interference between methanol and CO2 was observed. High methanol concentrations could make the instrument susceptible to false alarms, but this may reduce the real hazards associated with high concentrations of this flammable vapor. In a scenario where methanol, ethanol, and acetone vapors are high enough to trigger the smoke detector, and a fire is occurring at the same time, the algorithm would have detected the fire since CO2 concentrations would have risen due to the fire.
