Many people do not have fire alarm systems installed in their homes. Many assume that they are able to smell smoke when they are asleep and wake up in time to escape in case of a fire emergency. Well, this is not true at all. Studies have been conducted and it has been proven that people’s sleep are disrupted when there is sound or noise, but it is NOT the case with smell. Our sense of smell is lost when we are asleep, and we will not wake up no matter how strong the smell of smoke is.
