1. Smoke Detectors
Purchasing smoke detectors and installing and maintaining them properly is a good first step in prevention. There are two basic types of detectors: photoelectric alarms that are activated by smoke particles interrupting a beam of light within the device; and ionization types that contain a radioactive material such as americium-241 that ionizes the air in a small chamber thus creating a weak electric current.
