Fire Safety
Additional Recommendations
Smoke Detection. Where required by applicable laws,
codes, or standards for the specified occupancy, approved
single- and multiple-station smoke alarms shall be
installed as follows: (1) In all sleeping rooms Exception:
Smoke alarms shall not be required in sleeping rooms in
existing one- and two-family dwelling units. (2) Outside
of each separate sleeping area, in immediate vicinity of
the sleeping rooms. (3) On each level of the dwelling
unit, including basements Exception: In existing one- and
two-family dwelling units, approved smoke alarms
powered by batteries are permitted. Check with local
officials for specific regulations concerning your situation.
The required number of smoke alarms might not provide
reliable early warning protection for those areas separated
by a door from the areas protected by the required smoke
alarms. For this reason, it is recommended that the
householder consider the use of additional smoke alarms
for those areas for increased protection. Additional areas
include the basement, bedrooms, dining room, furnace room,
utility room, and hallways not protected by the required
smoke alarms. The installation of smoke alarms in kitchens,
attics (finished or unfinished), or garages is not normally
recommended, as these locations occasionally experience
conditions that can result in improper operation.
NRC
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.
CPSC
The Consumer Product Safety Commission (CPSC)
recommends the use of at least one CO Alarm per
household, located near the sleeping area.
