Where the width of the walking surface at the top of the ramp nasi parallel to the run of the ramp is less than 48 in mm wide, the flared sides shall have a slope not steeper than 1: Although people who use walking aids do maneu- ver through clear width openings of 32 in mmthey need passageways and walks that are 36 in mm wide for a comfortable gait.
The information must be tai- lored to the specific facility, its emergency plan, and the intended audience.
CABO/ANSI A, –
The highest operable parts that are essential to the use of the telephone shall be located within the reach ranges specified in 4. Such characters shall be 2 in 51 mm high nomi- nal and shall comply with 4. Space between two hinged or pivoted doors in series shall be 48 in mm minimum plus the width of any door swinging into the space.
Built-up curb ramps shall be located so that they do not protrude into vehicular traffic lanes or into parking space access aisles.
The access route therefore is to be wider if the wheelchair user negotiates a turn around a narrow obstacle.
Within this in mm width, the ambulatory person has to twist to pass a wheelchair user, a semi- ambulatory person, or a person with a seeing eye dog. Accessible washing machines and clothes dryers in common-use laundry rooms shall be front loading and shall comply with 4.
An accessible pedestrian space be- tween elements, such as parking spaces, seating, and a17, that provides clearances appropriate for use of the elements.
When so sloped, a change in elevation naturally occurs. An accessible route with a clear width less than 60 in mm shall provide passing spaces at intervals of ft 61 m maxi- mum.
The dis- tance from the front edge of a counter within the enclosure to the face of the telephone unit shall be 20 in 51 mm maximum. The seat wall must be free of grab bars to allow a person to slide onto the seat and a portion of the adjacent back wall must be without a grab bar so the person’s back can be placed against the walls for support.
Opening forces are measured with a spring scale as follows: Controls in roll-in showers shall be located on the back wall 38 in to 48 in mm to mm above the shower floor. Accessible Elements and Spaces 4. Coat hooks provided within toilet stalls shall be 54 in mm maximum above the floor.
When a new car position a1117 is installed, the annsi shall comply with 4. The clear floor space shall be permitted to extend 19 in mm maxi- mum underneath the counter.

Sinks in kitchens of accessible dwelling units shall comply with 4. Accessible openings located in these areas sometimes require modification of this aansi tion or possibly the use of automatic or power- assisted doors to comply with allowable forces given.
For this edition, substantial effort was devoted to removing from the Standard informational statements and application criteria scoping requirements such as where, when, and to what extent the criteria will apply to the built environment. Enclosures for show- er stalls shall not obstruct controls or obstruct transfer from wheelchairs onto shower seats. Refrigerators and freezers shall comply with 4.
If the side reach is over an ob- struction, the high reach shall be 46 in mm maximum providing: Rounding of corners as necessitated in the manufacture of pre- fabricated shower stalls does not interfere with use. However, some people who use walking aids have difficulty with ramps and prefer stairs.
The ability to man- age an incline is related to both its slope and its length. Raised charac- ters and symbols shall be in uppercase characters. Examples of 199 are telephones, curb ramps, doors, drinking fountains, seating, and water closets. Enclosures for bath- tubs shall not obstruct controls or transfer from wheelchairs onto bathtub seats or into tubs.
The additional force to overcome the inertia of a door exceeds that required to maintain movement of the door. Dashed lines indicate minimum length of clear space required on each arm of the T-shaped space in order to complete the turn.
Control buttons shall be raised, flush or recessed.
Individuals with low vision may have poor acuity or depth perception and can not reliably see low lying protruding objects. This standard provides specifications for elements that are used in making functional spaces accessi- ble. Accessible stairs shall comply with 4. Openings more than 24 in mm deep shall comply with 4. People over 60 years of age generally have difficulty perceiving frequencies higher than 4, Hz.
Toe clearance is not required in stalls greater than 60 in 1 mm deep. The path of egress travel from an area of refuge to the public way frequently involves supervised or assisted use of elevators or stairs.
For such people, a stable and regular surface is necessary to walk safely. It serves as a staging area which provides relative safety to its occupants while potential emergencies are assessed, deci- sions are made, and mitigating activities are begun.

Allowable stresses in bending, shear and tension shall not be exceeded for materials used when a vertical or horizontal force of lb 1 1 12 N is applied at any point on the grab bar, seat, fastener mounting device or supporting structure. The nature of certain specialized communication equipment and similar equipment precludes instal- lation at the specified locations.
Electrical and communications-sys- tem receptacles on walls shall be mounted 1 5 in mm minimum above the floor unless the use of special equipment requires location at a different position. The highest oper- able part of a two-way communication system shall be 54 in mm maximum above the floor for parallel approach and 48 in mm maximum above the floor for front approach.
The elevator industry recommends the button be identified by the symbol “S” and be located with, immediately above or immediately below the emergency but- tons on the car operating panel.
