Why are smoke detectors and alarms necessary?

Bottom line, smoke detectors save lives and in the event of a fire can give you the early notice necessary for a quick exit. Since nearly all fatal home fires occur at night, smoke detectors provide the necessary jolt to awaken a household and warn them of the impending danger. Toxic gases and fumes can sometimes make it almost impossible to rely on your own senses. Smoke detectors will essentially replace your senses and give you a better chance of survival if a fire should occur.
