OSHA
STANDARD 1910.24 FIXED INDUSTRIAL STAIRS
|
|
|
|
| 1910.24(a)
"Application
of requirements." This section contains specifications
for the safe design and construction of fixed general
industrial stairs. This classification includes interior and
exterior stairs around machinery, tanks, and other equipment,
and stairs leading to or from floors, platforms, or pits.
This section does not apply to stairs used for fire exit purposes,
to construction operations to private residences, or to articulated
stairs, such as may be installed on floating roof tanks
or on dock facilities, the angle of which changes with the
rise and fall of the base support.
..1910.24(b)
1910.24(b)
"Where fixed
stairs are required." Fixed stairs shall be provided
for access from one structure level to another where
operations necessitate regular travel between levels, and
for access to operating platforms at any equipment which
requires attention routinely during operations. Fixed stairs
shall also be provided where access to elevations is daily
or
at each shift for such purposes as gauging, inspection, regular
maintenance, etc., where such work may expose
employees to acids, caustics, gases, or other harmful substances,
or for which purposes the carrying of tools or
equipment by hand is normally required. (It is not the intent
of this section to preclude the use of fixed ladders for
access to elevated tanks, towers, and similar structures,
overhead traveling cranes, etc., where the use of fixed ladders
is common practice.) Spiral stairways shall not be permitted
except for special limited usage and secondary access
situations where it is not practical to provide a conventional
stairway. Winding stairways may be installed on tanks and
similar round structures where the diameter of the structure
is not less than five (5) feet.
1910.24(c)
"Stair strength."
Fixed stairways shall be designed and constructed to carry
a load of five times the normal live load
anticipated but never of less strength than to carry safely
a moving concentrated load of 1,000 pounds.
1910.24(d)
"Stair width."
Fixed stairways shall have a minimum width of 22 inches.
1910.24(e)
"Angle of
stairway rise." Fixed stairs shall be installed at angles
to the horizontal of between 30 deg. and 50 deg. Any
uniform combination of rise/tread dimensions may be used that
will result in a stairway at an angle to the horizontal
within the permissible range. Table D-1 gives rise/tread dimensions
which will produce a stairway within the permissible
range, stating the angle to the horizontal produced by each
combination. However, the rise/tread combinations are not
limited to those given in Table D-1.

_______________________________________________________
..1910.24(f)
1910.24(f)
"Stair treads."
All treads shall be reasonably slip-resistant and the nosings
shall be of nonslip finish. Welded bar grating
treads without nosings are acceptable providing the leading
edge can be readily identified by personnel descending the
stairway and provided the tread is serrated or is of definite
nonslip design. Rise height and tread width shall be uniform
throughout any flight of stairs including any foundation structure
used as one or more treads of the stairs.
1910.24(g)
"Stairway
platforms." Stairway platforms shall be no less than
the width of a stairway and a minimum of 30 inches in
length measured in the direction of travel.
1910.24(h)
"Railings
and handrails." Standard railings shall be provided on
the open sides of all exposed stairways and stair
platforms. Handrails shall be provided on at least one side
of closed stairways preferably on the right side descending.
Stair railings and handrails shall be installed in accordance
with the provisions of 1910.23.
1910.24(i)
"Vertical
clearance." Vertical clearance above any stair tread
to an overhead obstruction shall be at least 7 feet
measured from the leading edge of the tread.
