power to operate the door in emergencies. This provision has limited application and will

ffect, among others, in-swinging automatic doors that serve small spaces.
Commenters urged the Department to reconsider provisions that would require
maneuvering clearance or standby power for automatic doors. They assert that these
requirements would impose unreaso
nable financial and administrative burdens on all
c
overed entities, particularly smaller entities. The Department declines to change these
provisions because they are fundamenta
l life-safety issues. The requirement applies only
to
doors that are part of a means of egress that must be accessible in an emergency. If an
emergency-related p
ower failure prevents the operation of the automatic door, a person
w
ith a disability could be trapped unless there is either adequate maneuvering room to
open the door manually, or there is a back-up power source.
hresholds at Doorways. The 1991 Standards at section 4.13.8 require thresholds at
T
doorways not to exceed ½ inch; and thresholds at exterior sliding doors not to exceed ¾
inch. Proposed sections 404.1 and 404.2.5 will require thresholds at all doorways that are
part of an accessible route not to exceed ½ inch. The 1991 Standards and the proposed
regulations require raised thresholds that exceed ¼ inch to be beveled
on each side with a
sl
ope not steeper than 1:2. The proposed standards include an exception that exempts
existing and altered thresholds that do not exceed ¾ inch and are beveled on each side
from the requirement.
407 Elevators
Section 407.4.8.2, Audible Indicators, and section 407.4.8.2.1, Signal Type, provide tha
t
an elevator signal shall be an automatic verbal annunicator tha
t announces the floor at
w
hich the car is about to stop.
A
commenter noted that requiring an audible signal for elevators is important; however,
the requirement that the signal be a verbal annunicator, presumably in English, is
troubling to building owners and operators whose buildings may be located in multi-
lingual communities or international tourist destinations. The commenter suggested that
the 1991 Standard’s requirement for chimes or tones, once for up and twice for down,
should be retained and the requirement for a verbal annunciation deleted from the
proposed standards.
The proposed standards, at section 407.2.2.3 permit building operators to choose an
audible signal or a verbal annunciator to indicate the direction in which the elevator is
traveling. Section 407.4.8 provides an additional requirement for a verbal annunciator
to
identify the floor at which the elevator is stopping
. This requirement is for an
a
nnouncement within the elevator car to notify passengers of floor arrival. The
Department will retain the requirement as drafted because the verbal annunciator
provides more detailed locator information than would be provided by just the use
of an
audible signal. The Department notes, however, that nothing in the guidelines would
preclude a building operator from providing this information in a language – or languages
– other than English when the building operator deems it appropriate.
