Alternating tread devices. |
1011.14.2
Treads of alternating tread devices. |
Alternating
tread devices are limited to an element of a
means of egress in buildings of Groups F, H and S
from a mezzanine not more than 250 square feet (23 m²)
in area and that serves not more than five occupants; in
buildings of Group I-3 from a guard tower, observation
station or control room not more than 250 square feet
(23 m²) in area and for access to unoccupied roofs.
Alternating tread devices used as a means of egress
shall not have a rise greater than 20 feet (6096 mm)
between floor levels or landings. |
Alternating
tread devices shall have a minimum tread
depth of 5 inches (127 mm), a minimum projected
tread depth of 8 1/2 inches (216 mm), a minimum
tread width of 7 inches (178 mm) and a maximum
riser height of 9 1/2 inches (241 mm). The tread
depth shall be measured horizontally between the
vertical planes of the foremost projections of adjacent
treads. The riser height shall be measured vertically
between the leading edges of adjacent treads. The riser
height and tread depth provided shall result in an angle
of ascent from the horizontal of between 50 and 70
degrees (0.87 and 1.22 rad). The initial tread of the
device shall begin at the same elevation as the platform,
landing or floor surface. |
|
| 1011.14.1
Handrails of alternating tread devices. |
Handrails
shall be provided on both sides of alternating
tread devices and shall comply with Section 1014. |

|
Exception:
Alternating tread devices used a an
element of a means of egress in buildings from a
mezzanine area not more than 250 square feet (23m²)
in area that serves not more than five occupants shall
have a minimum tread depth of 3 inches (76 mm) with
a minimum projected tread depth of 10 1/2 inches
(267 mm). The rise to the next alternating tread surface
shall not exceed 8 inches (203 mm). |

Walking-Working
Surfaces and Personal Fall Protection Systems Final Rule
Frequently Asked Questions
|
The
intent of OSHA’s Walking-Working Surfaces standard, 29
CFR Part 1910, Subpart D & I, is to increase the
protection of general industry employees and employers from
hazards associated with walking-working surfaces. The
rule making will significantly reduce the number of worker deaths
and injuries that occur each year resulting from
workplace slip, trip, and fall hazards. The final rule was published
on November 18, 2016, and became effective on
January 17, 2017. Some requirements in the final rule have compliance
dates after the effective date and will be
discussed in further detail below. This final rule and the associated
preamble, providing more detailed explanation of
the rule, is available on the Federal Register website at 81
FR 82494, Walking-Working Surfaces; Personal Protective
Equipment; Final Rule, November 18, 2016.
OSHA requirements are set by statute, standards, and regulations.
The Agency’s interpretations explain these require-
ments and how they apply to particular circumstances, but they
do not create additional employer obligations. Note
that our enforcement guidance may be affected by legislative
or rule making changes to OSHA requirements. Also,
from time to time we update our guidance in response to new
information. To keep apprised of such developments,
you can consult OSHA’s website at http://www.osha.gov.
This webpage provides guidance, in a question and answer format,
regarding OSHA’s Final Rule, Walking-Working
Surfaces and Personal Protective Equipment, 29 CFR Part 1910,
Subpart D and I. These Frequently Asked Questions
(FAQs) are divided into five sections: general questions, rope
descent system (RDS) questions, outdoor advertising
questions, residential roof questions, and agricultural operation
questions. |
| Standard
Stairs |
Does
the exception to the 9.5-inch riser height and 9.5-inch tread
depth requirements for stairs installed before
January 17, 2017 (§19210.25(c)(5)), also apply to stairs
designed and fabricated, but not yet installed, by that date? |
Stairs
with design drawings issued for construction or that were in
fabrication before January 17, 2017, but not
installed, will be in compliance if they met the previous requirements
for standard stairs. |
|
Under
the previous standard, stairs with a handrail that doubles as
a stair rail could have a rail height of 30 to 34
inches. If an employer's stairs were installed prior to January
17, 2017, must the rails have a minimum height of
36 inches if the stair rail doubles as a handrail? |
The
final rule does not affect stair rail systems and handrails
installed before January 17, 2017 that were in com-
pliance with the requirements in the old standard. |
|
Does
the requirement that standard stairs have a slope between 30
to 50 degrees apply to stairs installed after January
7, 2017. Therefore, the maximum angle for standard stairs is
45 degrees. |
Yes.
The final rule limits the maximum rise height and minimum tread
depth to 9.5 inches for standard stairs installed
after January 17, 2017. Therefore, the maximum angle for standard
stairs is 45 degrees. |
|
| Are
stairs installed after January 17, 2017, that have an angle
of 50 degrees considered to be ships stairs? |
The
final rule defines ship stairs as “a stairway that is equipped
with treads, stair rails, and open risers, and has a slope
of 50 to 70 degrees.” Ship stairs must also comply with
§1910.25(b) and (e), such as a minimum tread depth of 4
inches, a minimum tread width of 18 inches, and a vertical clearance
above any stair tread to any overhead
obstruction of at least 6 feet 8 inches. |
|
What
if the doorway described in §1910.25(b)(5)(ii) and shown
in figure D-7 is perpendicular to the direction of
travel and opens onto the landing? Does the same dimension apply
to this condition? |
Yes.
As figure D-7 illustrates, Section 1910.25(b)(5) requires that
a platform be provided when a door or a gate opens
directly onto a stairway. For platforms installed after January
17, 2017, the final rule also requires that employers
ensure the swing of the door or gate does not reduce the "effective
usable depth" of the platform to less than 22 inches (§1910.25(b)(5)(ii)).
The preamble to the final rule describes “effective usable
depth” as the portion of the platform
beyond the swing of the door where a worker can stand when opening
the door (82 FR 82557). The provision applies
equally to stairway doors that are perpendicular to the direction
of travel. |
|
Are
fixed stairs attached to the exterior of tanks required to comply
with the requirements of §1910.25(b) or would
those stairs fall under the exemptions in §1910.25(a)?
The exception from the stair requirements in §1910.25(a)
only applies to stairs serving floating roof tanks, stairs on
scaffolds, stairs on self-propelled motorized equipment, or
stairs designed into machines or equipment. For stairs on
the exterior of other tanks, employers would have to ensure
they comply with the requirements in §1910.25(b) and (c). |
|
Would
winding stairs attached to tanks be required to meet the requirements
in §1910.25(d) for spiral stairs?
No. Section 1910.21(b) defines spiral stairs as a "series
of treads attached to a vertical pole in a winding fashion,
usually within a cylindrical space" (emphasis added). Winding
stairs attached to tanks do not have vertical poles;
therefore, they are not spiral stairs and must meet the requirements
of §1910.25(b) and (c). |
|
Based
on the height requirements for stair rails and handrails and
the requirements in Table D-2, are both stair rails
and handrails required on stairs that have two open sides and
are less than 44-in. wide?
Yes. Section 1910.28(b)(11)(ii) Table D-2 contains a printing
error, which OSHA will correct in a published notice.
For each flight of stairs with two open sides and a width of
less than 44 inches, column 4 of Table D-2 should state
"One stair rail system with hand rail on each open side"
is required. (See 81 FR 82611-12). |
