Almost all aerosols, alcohols, paints, thinners, solvents, binders, hair sprays,
aftershaves, perfumes, car exhaust (cold start) and some detergents.
When the product is exposed to the above-mentioned gases, it may give
false alarms or be permanently damaged. When the alarms are activated
and you smell an irritating gas, this may be a false alarm, as CO is colorless

it means that the product has been polluted. You must place the unit in clean
air for 24 hours. If the product does not recover after this time, it means that
the sensor has been damaged and the product should not be used anymore.
