- Cleaning with flammable liquids, such as gasoline.
- Fires where the victim is intimate with a flaming initiated fire;
for example, when a person's clothes catch fire while cooking.
- Fires where the smoke is prevented from reaching the detector
due to a closed door or other obstruction.
- Incendiary fires where the fire grows so rapidly that an occupant's
egress is blocked even with properly located detectors
9. NRC INFORMATION
Ionization type smoke alarms use a very small amount of a radioactive element
in the sensing chamber to enable detection of visible and invisible combustion
products. The radioactive element is safely contained in the chamber and
requires no adjustments or maintenance. This smoke alarm meets or exceeds all
government standards. It is manufactured and distributed under license from
the U.S. Nuclear Regulatory Commission.
10. NFPA REQUIRED PROTECTION
The National Fire Protection Association’s Standard 72 provides the following
information:

the specified occupancy, approved single- and multiple-station smoke alarms
shall be installed as follows:
(1) In all sleeping rooms and guest rooms.
(2) Outside of each separate dwelling unit sleeping area, within 21 ft (6.4 m) of
any door to a sleeping room, with the distance measured along a path of
travel.
