    Default Different types of stairs.

    At the fire house today, we started talking about different types of stairs. We are having a discussion and a little of confusion about the terminology. Looking for help. Can anybody post pics/info of different types of stairs.

    -Straight run
    -Scissor Stairs
    -Return Stairs
    -Any other types that you may have


    Thank You

    Its been quite some time since I read anything about stairway terminology. This is what I can pull from my foggy memory, correct me if Im wrong.


    Straight -- Stairs proceed straight from one floor to another they may incorporate a landing but the top and bottom of the stairwell is not at the same spot on the floors

    Scissor stairs --scissor stairs incorporate 2 stairwells into the same area. when looked at from the side, you see an "X" pattern.

    Return stairs -- stairs incorporate a landing at midpoint that then "returns" to the same area of the other floor. In other words, the top and bottom of the stairwell is located at the same point on each floor.

    Add to your list an alternating tread stair. Not particularly common, but it's almost a cross between a ladder and a stair. It is found mostly in industrial applications and some smaller old homes because it allows a straight run of stairs in a much shorter horizontal run.

    Is that something you heard in south Jersey due to it being close to Philly or have you heard it elsewhere? Up north or another state?

    Actually, had an instructor at Jersey City State in 1978 from Hoboken FD talk about in a Building Construction class. I never heard it anywhere else.

    . . 18 . . If you never heard of it then I think it might have been some in house thing from the Hoboken guy back then.

    During a recent training class, we discussed the following types of stair configs...

    1.) Open Well Hole (1 length of hose per 4-5 floors)
    2.) Simple/ Return (1 length of hose per 2-3 floors)
    3.) Wrap Around (Elevator) (1 length of hose per 1 floor)

    Our discussion revolved around hose stretches related to the types of stairs when going up multiple flights.

    Is that applicable?
