CommitteeStatement:

It is difficult-to-impractical to provide 7’-6” headroom height at an intermediate landing if

the headroom on the stair is designed to take advantage of the 6’-8” headroomallowance. The headroom is there to provide a smoke reservoir to permit smoke to bankdown from the ceiling without immediately affecting the movement of an occupant who isstanding. Within an exit stair enclosure – except for the top floor landing – the smoke willtravel upward along the rake of the stair to a higher level rather than accumulating underthe landing. The basis for the headroom requirement seems not to be served any betterby a 7’-6” headroom than one of 6’-8”.

The MEA Egress Committee reviewed the detailed justification submitted with theassociated NFPA 101 PI on which an FR is making similar changes to NFPA 101. Theinjury and death problem with bathtub/shower falls demands attention, as well, inNFPA 5000.

The committee positioned the new material as 7.1.6.5 as it is tied to the other items in7.1.6 related to walking surfaces. MEA is not mandating that grab bars be provided.Rather, it is creating a menu that can be mandatorily referenced by other provisions ofthe Code.

A.11.1.6.5 The grab bars required by 11.1.6.5 are designed to improve safety of showering and

bathing by ambulatory users, typically entering and exiting a bath, bathtub-shower combination

or shower facility for showering while standing or for other forms of bathing which can entail

transition to/from a crouching or sitting position.

For grab bar requirements appropriate for other uses and users, especially users with disabilities,

refer to requirements in ICC/ANSI A117.1, Standard for Accessible and Usable Buildings and

Facilities. Generally, the grab bars specified for this Code will not interfere with other grab bars

installed in accordance with requirements of ICC/ANSI A117.1 and they can contribute to

meeting the requirements of ICC/ANSI A117.1 and vice versa. For example, combination

vertical and horizontal grab bars (in an L configuration), as addressed by ICC/ANSI A117.1, can

meet the requirements of this Code for a vertical grab bar. Similarly requirements for a

horizontal grab bar on the back wall are compatible.

Dimensions for height of grab bars are based on typical, mass-produced bathtubs with a wall

height, above the finished floor of about 15 in. (380 mm) and the bottom of the bathtub within 1

to 2 in. (2.5 to 5 mm) of the finished floor elevation. Adjustments to stipulated grab bar height

limits and ranges, referenced to the bath tub rim, should be considered for bath tubs having

higher walls and, thus, rim heights, above the bottom of the tub and, possibly, also the wall

height above the finished floor. ICC/ANSI A117.1 references grab bar height dimensions to the

bathtub rim and, for consistency with this widely used ANSI standard, that convention is

maintained in this Code.

A.11.1.6.5.1.2 The provision of 11.1.6.5.1.2 is intended to ensure that grab bars, if provided

voluntarily—i.e., as non-required—for dedicated showers, meet the requirements of the

section—so that something appearing to be a grab bar can effectively perform as one. However

such grab bars would only be considered non-required in the case of dedicated showers not

involving misstep and fall dangers addressed by 11.1.6.2 and 11.1.6.4. This means that walking

surfaces must be at least as safe, in terms of underfoot conditions, as any other portion of the

means of egress (where, for example, handrails are not required) for users not having mobility

disabilities. This would require exceptionally careful choice, and maintenance, of underfoot

materials as well as very effective control of water within and adjacent to the dedicated shower

facility.

A.11.1.6.5.2.1 Grab bars located where they interfere with sealing, with a shower curtain against

escape of water—especially to the floor surface outside the shower facility—might introduce

safety problems in the form of greatly reduced slip resistance of the walking surface (which

could violate this Code). This is avoided with a 6-in. (150-mm), horizontal separation between

the shower curtain rod and the grab bar. It is assumed that other forms of water control, such as

an installed enclosure, will not interfere with the use of grab bars.

A.11.1.6.5.2.2 A free-standing pole, satisfying requirements for a grab bar, can offer much

flexibility in placement, for example, within the close quarters of a small bathroom where there

is a water closet adjacent to the bathing facility and a single grab bar can serve both facilities.

Where the bathing facility is free standing, without walls, especially with large soaking tubs,

of 49

including those on pedestals, the vertical pole-type grab bar is especially useful. The pole also

can solve attachment problems where walls that are nonexistent or difficult to use for installing

conventional, wall-mounted grab bars.

A.11.1.6.5.3.1 Using the mid points of the distance ranges and the minimum distance from the

control end wall results in a 45-degree angle for the diagonal grab bar. Such a diagonal grab bar

(or alternatively, a horizontal grab bar fairly similar to the option provided by 11.1.6.5.3.1 which

meets requirements of ICC/ANSI A117.1) was found suitable in tests performed of several grab

bar options with 103 independent-living seniors with average age of 70. (“Evaluation of Optimal

Bath Grab Bar Placement for Seniors,” by H. Sveistrup, D. Lockett, N. Edwards and F.

Aminzadeh, University of Ottawa with funding by Canada Mortgage and Housing Corporation,

2003.)

A.11.1.6.5.4 The best performing grab bars are in the middle third of the permitted range for

circular diameter. For some grab bar designs, with undulations and other surface geometry

features to improve slip resistance for users’ hands, these dimensions will be nominal with small

variations depending on where measurements are taken. Children and others with smaller hands

will be able to use best the diameters within the lower part of the permitted range. When using a

free-standing pole for a grab bar, structural considerations, especially for stiffness, might dictate

using diameters in the upper part of the permitted range.

Note that a minimum clearance between the grab bar and an adjacent surface is specified. With

grab bars, especially horizontal ones, on which large, downward loads are imposed by the arms

of users, there is some concern about people’s hands slipping into the clear space; however this

can occur even with an absolute 1.5 in. (38 mm) clearance, as some standards specify and most

grab bar designs provide. Thus the main difference in the end result is where, along its length,

the arm gets wedged behind the grab bar, not the complete prevention of this happening at all.

(3) The interior exit discharge shall lead to a free and unobstructed way to the exterior of thebuilding, and such way shall be readily visible and identifiable apparent or shall beidentifiable by exit signage from the point of discharge from the exit.

(4) The interior exit discharge shall be protected by one of the following methods:

(a) The level of discharge shall be protected throughout by an approved automaticsprinkler system in accordance with Section 55.3, or the portion of the level ofdischarge used for interior exit discharge shall be protected by an approvedautomatic sprinkler system in accordance with Section 55.3 and shall be separatedfrom the nonsprinklered portion of the floor by fire barriers with a fire resistancerating meeting the requirements for the enclosure of exits. (See 11.1.3.2.1.)

The only change being made is to subitem (3).

The provision of 11.7.2(3) is routinely interpreted that exit signage meets the readilyvisible and identifiable unobstructed way requirement. Adding the exit signage languageto the Code makes the requirement explicitly clear and removes the need to interpretthe provision.

Committee Statement

CommitteeStatement:

By using the word "Beyond," the requirement, as it is currently written, applies tooccupants traveling in both directions past the level of exit discharge. This means thatwhere a stair has points of entry on levels above and below the level of exit discharge,the requirement to dissuade occupants from passing that level would apply in bothdirections. This would essentially create the need for multiple gates, doors, or othermeans of disrupting egress within the stair; one above and one below the level of exitdischarge.

By replacing the word "Beyond" with the word "Below," the requirement is clarified suchthat it only applies to occupants traveling in a downward direction past the level of exitdischarge.
