  • Summary of replies handrail heights

    Greetings,

    Thanks to all who responded to the balcony railing question. The original
    posting is followed by the summary. Thanks to those who offered additional
    follow up information.

    When examining building codes for handrail/wall heights for an elevated
    balcony, safety is the objective (so someone doesn't fall over an exposed
    side). However, individuals still fall over the side in certain instances.

    Can anyone point me to published studies that are used to determine what
    these heights should be? Also, someone who is falling (e.g., tripping on
    something, then recovering from a fall) will impose different dynamics when
    encountering this handrail/wall than someone leaning against it. Are there
    any works that describe this?


    'the measure of man and woman' from henry dreyfus associates is a set of
    guidelines for architects and designers. really nice reference book. all
    kinds of sizing specs/etc. safety. 1st % to 99%, etc.

    A good place to start is John Templer's book "The Staircase: Studies of
    Hazards, Falls and Safer Design" published by the MIT Press.

    You will certainly find something in Britsh Standards about this - also
    possibly European Codes on safety. I cannot direct you the a particular
    section, however architects and structural engineers have information on
    this.

    Hope this helps.

    Check out this site: http://www.nadra.org/consumers/deck_inspections.html It
    is stated that "the height of the railing is also regulated, with a height
    of 36 inches standard for residential properties and 42 or 48 inches most
    common for commercial and fencing applications." Give them a call to see if
    they know how these guidelines were formulated.

    Our lab has described some work measuring handrail dynamics in preventing
    stairway falls.
