Resumo

TLDRIn this video by NFPA Journal, the focus is on smoke alarm technologies designed for those who are deaf or hard of hearing. While traditional smoke alarms rely on sound, alternative technologies are explored. Olfactory alarms, which release fragrant mist to awaken people, are only effective in lighter sleep stages and not reliable for deep sleepers or those with nasal issues. Bed shakers, a common technology, effectively awaken 70-100% of users, though less so in older individuals. Another innovative concept is robot dogs, which can alert people by bumping into their bed. Though not commercially available yet, their potential use is promising, with Hyundai already planning to use robot dogs for fire hazard monitoring in factories. The video highlights over 360 million people suffering from disabling hearing loss, making these technologies crucial. The content also ties into Fire Prevention Week, emphasizing the importance of accessible fire safety solutions.

    The video introduces the challenge faced by deaf or hard of hearing individuals regarding traditional smoke alarms that emit a sound to indicate evacuation is necessary. With millions suffering from disabling hearing loss, alternative technologies exist or have been theorized. The Fire Protection Research Foundation has reviewed various alarm technologies, and the video will examine three specific options that could potentially awaken those with hearing impairments during a fire: olfactory alarms, bed shakers, and robot dogs.

    if you go to your local hardware store
  • 00:00:02
    and start shopping around for smoke
  • 00:00:03
    alarms you'll find something that looks
  • 00:00:06
    like this
  • 00:00:07
    in the event of a fire the alarm will
  • 00:00:09
    beep
  • 00:00:13
    but what if you're somebody who can't
  • 00:00:14
    hear that beep what sort of smoke alarm
  • 00:00:17
    technologies exist for people who are
  • 00:00:19
    deaf or hard of hearing

  • 00:00:30
    as far back as the late 1800s people
  • 00:00:33
    have been experimenting with heat and
  • 00:00:35
    smoke detection devices meant to save
  • 00:00:37
    people from dying and fires
  • 00:00:39
    one such development came in the late
  • 00:00:41
    1930s when a swiss physicist tried but
  • 00:00:44
    failed to invent a poison gas detector
  • 00:00:47
    frustrated the scientist lit a cigarette
  • 00:00:49
    and to his surprise his device was
  • 00:00:52
    triggered it could detect smoke in the
  • 00:00:54
    air over the decades new smoke alarm
  • 00:00:56
    technologies emerged and today codes
  • 00:00:59
    require smoke alarms in most homes in
  • 00:01:01
    the u.s and many other countries
  • 00:01:03
    the vast majority of them use an audible
  • 00:01:06
    signal to let folks know it's time to
  • 00:01:08
    evacuate but what if you can't hear that
  • 00:01:10
    audible signal according to the world
  • 00:01:12
    health organization over 360 million
  • 00:01:15
    people that's more than the entire u.s
  • 00:01:17
    population suffer from disabling hearing
  • 00:01:20
    loss
  • 00:01:21
    for these individuals you might be
  • 00:01:23
    surprised to learn about some of the
  • 00:01:25
    technologies currently out there and
  • 00:01:27
    some that have been theorized to help
  • 00:01:29
    solve this problem
  • 00:01:31
    in august the fire protection research
  • 00:01:33
    foundation released a report reviewing
  • 00:01:35
    both real world and theoretical alarm
  • 00:01:37
    technologies for people who are deaf or
  • 00:01:39
    hard of hearing and in today's episode
  • 00:01:42
    we'll be taking a look at three of them
  • 00:01:44
    which research has shown have varying
  • 00:01:45
    levels of success in terms of being able
  • 00:01:47
    to wake up sleeping individuals in the
  • 00:01:49
    event of a fire
  • 00:01:50
    be sure to click the link to the full
  • 00:01:52
    foundation report which can be found in
  • 00:01:54
    the description of this video to learn
  • 00:01:56
    more about these three technologies and
  • 00:01:58
    several others
  • 00:02:00
    one
  • 00:02:01
    olfactory alarms
  • 00:02:04
    can smells wake you up it's a question
  • 00:02:06
    that's actually been at the heart of
  • 00:02:08
    debate for many years in research
  • 00:02:10
    studies newspaper articles and even just
  • 00:02:12
    online forums there's no shortage of
  • 00:02:15
    people out there claiming to have been
  • 00:02:16
    woken up by the smell of bacon on more
  • 00:02:18
    than one occasion but were they really
  • 00:02:21
    or did they just happen to wake up and
  • 00:02:22
    smell bacon
  • 00:02:24
    well there's at least enough credence
  • 00:02:25
    and nasal wake-up calls to warrant alarm
  • 00:02:28
    technologies that spray fragrant mist
  • 00:02:30
    into the air
  • 00:02:31
    studies however have shown that while
  • 00:02:33
    smells can wake you up in lighter stages
  • 00:02:35
    of sleep they're not that reliable in
  • 00:02:37
    deeper stages in the foundation report
  • 00:02:40
    authors eric smedberg and enrico ranki
  • 00:02:43
    of lund university in sweden also note
  • 00:02:46
    that people who suffer from seasonal
  • 00:02:47
    allergies or regular nasal congestion
  • 00:02:50
    might not wake up from smells
  • 00:02:52
    currently olfactory alarms seem to only
  • 00:02:54
    be commercially available for
  • 00:02:56
    non-emergency uses
  • 00:02:58
    and based on the science out there it's
  • 00:03:00
    probably best that it stays that way
  • 00:03:02
    2. bed shakers
  • 00:03:04
    perhaps the most common alarm technology
  • 00:03:06
    for deaf people are devices that shake
  • 00:03:09
    their bed or pillow over the years
  • 00:03:11
    various studies have shown these devices
  • 00:03:13
    are anywhere from 70 to 100 percent
  • 00:03:16
    effective at waking people up although
  • 00:03:18
    older people do tend to respond less
  • 00:03:20
    favorably right now a number of
  • 00:03:22
    commercially available options exist for
  • 00:03:24
    people who are deaf to use a bed shaker
  • 00:03:26
    not only to alert them of fires but also
  • 00:03:29
    simply to wake up in the morning
  • 00:03:31
    typically the device is plugged into the
  • 00:03:32
    wall and actually connect to another
  • 00:03:34
    device that is triggered by the sound of
  • 00:03:36
    a traditional alarm
  • 00:03:39
    the authors of the recent foundation
  • 00:03:40
    report conclude that bed shakers do seem
  • 00:03:43
    to be a reliable way to wake deaf and
  • 00:03:45
    hard of hearing individuals up 3.
  • 00:03:48
    robot dogs
  • 00:03:50
    here's where things get interesting let
  • 00:03:52
    me say that again robot dogs
  • 00:03:55
    in 2017 a study by japanese researchers
  • 00:03:58
    examined whether a robot dog could mimic
  • 00:04:00
    the actions of a real dog which deaf
  • 00:04:03
    people sometimes use to alert them of
  • 00:04:04
    emergencies the researchers even built a
  • 00:04:07
    prototype that would bump into a
  • 00:04:08
    person's bed to wake them up a small
  • 00:04:11
    trial they conducted showed all 10
  • 00:04:12
    participants whose hearing loss was
  • 00:04:14
    simulated with earplugs woke up within
  • 00:04:17
    20 seconds of the robodog intervening
  • 00:04:20
    while nothing's commercially available
  • 00:04:21
    yet in a similar development major
  • 00:04:24
    automaker hyundai announced last month
  • 00:04:26
    that it would be employing a robot dog
  • 00:04:28
    courtesy of boston dynamics to monitor
  • 00:04:31
    working conditions at one of its
  • 00:04:32
    factories in south korea spotting
  • 00:04:34
    potential fire hazards and detecting
  • 00:04:36
    temperature spikes are two of many jobs
  • 00:04:39
    the robot will be reportedly taking on
  • 00:04:42

    prevention week and this year's theme is
  • 00:04:54
    all about smoke alarms that also
