243 Shooting Facilities with Firing Positions
Sections 243 and 1010 will require an accessible turning space for each different type of
firing position at a shooting facility if de
signed on site. Where fitting positions are
p
rovided in clusters, five percent (5%), but at least one position of each type in each
cluster will have to be accessible.
Additional Technical Requirements
3
04 Turning Space
The turning space is required to be 60 inches diameter minimum and is permitted to
include knee and toe clearance.
Commenters urged the Department to retain the turning space requirement, but exc
lude
knee and toe clearance from being permitted as part of this space. Th
ey argued that
w
heelchairs and other mobility devices are becoming larger and that more individuals
with disabilities are using electric three- and fou
r-wheeled scooters.
The Department recognizes that there is a growing perception that the 1991 Standard
s,
which are based on wheelchair dimensions, may not adequately meet the needs of pe
ople
using some larger electric scooters. However, there is no consensus about the appropria
te
dimension on which to base revised requirements. The Department is aware that the
Access Board is financing an extensive study of this issue in order to determine if n
ew
requirements
are warranted. The Department plans to wait for the results of this study
b
efore changing the specifications in the Department’s rules.

utomatic Door Break-out Openings. The proposed standards do not contain any
A
technical requirement for automatic door break out openings. The proposed standard
s at
sections 404.1; 404.3; 404.3.1; and 404.3.6 will require automatic doors that are part of a
means of egress and that do not have standby power to have a 32 inch minimum clear
break out opening when operated in emergency mode. The minimum clear opening
width for aut
omatic doors is measured with all leaves in the open position. Automatic bi-
p
arting doors or pairs of swinging doors that provide a 32 inch minimum clear break out
opening in emergency mode when both leaves are opened manually meet the technic
al
requirement. The proposed regulation includes an exception that exempts automatic
doors from the technical requirement for break-out openings when accessible manual
swinging doors serve the same means of egress.
Maneuvering Clearance or Standby Power for Automatic Doors. The 1991 Standards,
se
ction 4.13.6, do not require maneuvering clearance at automatic doors. Section

a
n accessible means of egress to either provide maneuvering clearance or to have standby
