What the CPSC Data Shows
Fire Or Smoke Alarms (CPSC product code 702, in the Home Heating & Cooling Equipment category) generate an estimated 1,555 emergency-room visits every year in the United States, adding up to roughly 31,096 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 40/100 for this category (moderate risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are rising by about 38% over the last five years, with the busiest year on record being 2024 (3,261 estimated ER visits) and the quietest 2010 (614 estimated visits).
The single most common ER diagnosis for fire or smoke alarms is anoxia to the all parts body, accounting for approximately 6,234 visits across the 20-year NEISS window, followed by internal injury to the head (2,497 cases). The 75+ age group absorbs the largest share of injuries, about 5,802 cases over the NEISS window, and females appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 11.2% of ER visits involving this product end in hospital admission or transfer.
Beyond the hospital-sampled NEISS projections, this page also aggregates 260 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how fire or smoke alarms fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

Had a pack of 6 First Alert smoke detector professionally installed in our home after we purchased it to update and they have been in now about 8 months. They all went off one day and we didnt know why and smelt a strong electrical smell and had to call the fire department they couldnt tell where to smell was coming from or find heat with heat gun. We have had the strong electrical smell in our home and different smoke detectors going off at different times finally started pulling down the smoke detectors and they are all burnt up and could have caught our home on fire if we didnt find this.
I think it is extremely important that a nation wide warning or alert be issued regarding the replacement of older model smoke alarms that may tie into a sprinkler flow switch (on any home that is equipped with a sprinkler system). Many of these types of alarms switched 120 VAC household current onto the interconnect wire. Modern smoke alarms utilize a 9 volt transistor battery as a backup. This is not a problem for new construction, but anyone contemplating a replacement of an older style smoke alarm should confirm the manufacturer type or model number. One very popular smoke alarm (that is no longer being sold or manufactured) was the Firex 428C. In fact this device was the unit of choice for anyone with a sprinkler system up to three (3) years ago. If you were to replace this unit with a modern [REDACTED] smoke alarm (as an example), wired it up in accordance with the instructions, and the flow switch tripped you would destroy all the interconnected detectors in the home and may even cause a fire. It may also be prudent to issue a warning about ensuring any alarms you do replace are compatible with each other and from the same manufacturer.
We had seven Kidde talking smoke/carbon monoxide detectors (KN-COSM-IB) in our home (manufactured in November 2010), and none of the smoke detectors work. We had a small fire in the kitchen, and none of the detectors triggered or sounded the alarm. It seems that they were/are not working, but we have fresh batteries in them, and when you press the test/reset they beep. But they don't seem to detect smoke or carbon monoxide, and don't seem to work/function properly. We took them back to Home Depot (in Homers Glen) and then took them to Menards (in Homer Glen, IL) and they would not take them back or exchange them (under the recall). We're extremely unhappy that Kidde made smoke/carbon monoxide detectors that don't function or work properly, and the vendors have failed to replace/exchange them.
First Alert brand, Model No P1210, Single Station, Photoelectric, 10 Year Lithium Battery, Smoke Alarm Smoke alarms fail before 10 year life. False alarm sounds. I bought 10 of these items (five 2-packs) from Costco in Mountain View, CA in July-August 2014. I installed the smoke alarms on 8/2/2014. 6 of the 10 smoke alarms have failed as of 9/8/2015.
I had purchased a First Alert 120V AC hardwired smoke & fire alarm (model 9120B) earlier this year. I selected this model because it has a battery backup with an [REDACTED] 9V battery included. The battery was in its swing-out battery compartment. In the User's Manual, it did not instruct how to properly install in the battery. There were no markings on the alarm itself for where the battery's positive terminal should be place. So, I left the battery in the same place in its swing-out battery compartment as it was when I purchased this alarm. I pushed the door closed. Then, I noticed an opening under the swing-out battery compartment where I can see the battery's terminals. They were touching only plastic. I opened the swing-out battery compartment, and noticed that part of the compartment covers one of the battery's terminals. The battery is useless. It does not connect to anything electrical. There are no instructions in the User's Manual on how to install the battery, nor markings on the alarm itself on how to install the battery. Having the battery in the alarm is false security, and in case the hardwiring fails, the alarm will not have any electricity because the battery won't be installed properly. People depending on the battery backup could possibly die in the event of a fire.
As we came home on Saturday evening we heard the fire alarms go off. After several types of attempts at silencing them, they shut off, except one. It chirped every 30s the rest of the night. It was finally disconnected Sunday morning with the help of a neighbor. Our poor cat was certainly in terror over this ordeal. Why didn't Kidde notify the builder that there was a problem with the product. I have heard two other homes in the community with the alarms sounding.
Kidde 10 year smoke alarm Model P3010L is only 1 year old and is going off randomly when there is no smoke. I blew air into it as advised from the manufacturer and this made no difference. It is a fire hazard because it has to be removed in order to sleep.
Note: As the CPSC is aware from my previous complaints on this issue, I am a Deputy Chief on the Boston Fire Dept. I have contacted the St. Charles Fire Dept. and will send them a copy of this complaint. However, since I am not a member of the local fire dept. I am forwarding this as a civilian. There were 4 victims in this fire: [REDACTED] (F-30), [REDACTED] (M-27), [REDACTED] (M-8), & [REDACTED] (F-2). In this fire (see news report below) the victims were trapped by a fire that apparently started near the kitchen. It is likely that this fire produced copious amounts of smoke into the living areas and egress paths before it was heavily flaming. There were multiple smoke alarms, all ionization, installed in this house. Here their locations. Living Room (Ion alarm - melted on floor, in debris manufacturer unknown interestingly this was found by insurance investigator similar to complaint I filed with CPSC from Rotterdam NY)) Common Stairwell (Ion alarm - melted on floor, in debris manufacturer unknown) Basement (Ion alarm non operational) Garage (Ion alarm First Alert, no battery which would be expected of an alarm located in a garage) Bedrooms 3 and 4 (Ion alarm - Family Gard melted but with batteries) Bedroom 2 (No alarm) Master Bedroom (Kidde 0916 with a battery) In this case all the smoke alarms were ionization. (The CPSC should not be surprised since CPSC estimates that 90% of all alarms are ionization.) In this fire the occupants appear to have been awakened by the smoke alarms. According to the one survivor, [REDACTED], he heard smoke alarms after being awoken by [REDACTED]. It appears that many if not all occupants acted in an altruistic and proper manner but did not have enough time to safely escape. It is highly probable that they did not have enough time because the ionization smoke alarms did not operate in time to provide adequate warning from smoke build-up. The 2 most important alarms were
