Pool lifts must be located where the water level is not deeper than 48 inches. This provides the opportunity for someone to aid from a standing position in the water if desired. If multiple pool lift locations are provided, only one must be where the water is less than 48 inches. If the entire pool is deeper than 48 inches, an exception allows operators to use a pool lift in any location as an accessible means of entry.
There are a variety of seats available on pool lifts and these guidelines do not specify the type of material or the type of seat required. However, lift seats must be a minimum of 16 inches wide. In the raised (load) position, the centerline of the seat must be located over the deck, a minimum of 16 inches from the edge of the pool. The deck surface between the centerline of the seat and the pool edge cannot have a slope greater than 1:48.
Although not required, seats with backs will enable a larger number of persons with disabilities to use the lift independently. Pool lift seats made of materials that resist corrosion, that provide a firm base, and that are padded are more usable. Headrests, seat belts, and additional leg support may also enhance accessibility and accommodate a wider variety of people with disabilities.
Clear Deck Space
Clear deck space must be provided to enable a person to get close enough to the pool lift seat to easily transfer from a wheelchair or mobility device. This clear deck space will ensure an unobstructed area for transfers between a mobility device and the seat. The clear deck space must be a minimum of 36 inches wide and extend forward a minimum of 48 inches from a line located 12 inches behind the rear edge of the seat. This space must be located on the side of the seat opposite the water. The slope of the clear deck space must not be greater than 1:48 (2%). This virtually flat area will make the transfer area easier and safer, while still allowing water to drain away from the deck.
The lift must be designed so that the seat will make a stop between a minimum of 16 inches and maximum of 19 inches (measured from the deck to the top of the seat surface, when the seat is in the raised position). Lifts can provide additional stops at various heights to accommodate users of all ages and abilities.
Footrests and Armrests
Footrests and armrests provide stability for the person using the lift. Footrests must be provided on pool lifts, and must move together with the seat. Padding on footrests - large enough to support the whole foot - reduces the chance of injury.
Armrests are not required, however if provided, the armrest opposite the water must be removable or be able to fold clear of the seat when the seat is in the raised (load) position. This clearance is needed for people transferring between the lift and a mobility device.
Lifts must be designed and placed so that people can use them without assistance, although assistance can be provided if needed. A person must be able to call the lift when it is in either the deck or water position. It is especially important for someone who is swimming alone to be able to call the lift so he or she won’t be stranded in the water for an extended period of time.
The controls and operating mechanisms must be unobstructed when a lift is in use. A person must be able to use the lift with one hand, and the operating controls must not require tight, grasping, pinching, or twisting of the wrist. Controls may not require more than five pounds of pressure to operate.
Lifts must be designed so that the seat will submerge to a minimum of 18 inches below the stationary water level. This will ensure buoyancy for the person on the lift and make it easier to enter and exit.
Lifts must have the capability of supporting a minimum weight of 300 pounds and be capable of sustaining a static load that is at least 1.5 times the rated load. Where possible, lifts that can support a greater weight capacity are encouraged.
Sloped entries must comply with ADAAG accessible route provisions (36 inch minimum width, maximum 1:12 or 8.33% slope), except that the surface does not need to be slip resistant. The slope may be designed as zero grade beach or ramp access. With either design, the maximum slope permitted is 1:12.
In most cases, it is not appropriate to submerge personal wheelchairs and mobility devices in water. Some have batteries, motors, and electrical systems that can be damaged or contaminate the pool. Facilities that use sloped entries are encouraged to provide an aquatic wheelchair designed for access into the water. Persons transfer to the aquatic wheelchair and access the water using it, leaving their personal mobility device on the deck. Operators and facility managers may need to consider storage options for personal mobility devices if deck space is limited.
The coefficient of friction for slip-resistance on ramped surfaces should be 0.8.
C701 tile exceeds maximum slopes for ADA accessible ramps. If a ramp is designed to be fully ADA compliant, it should not be installed or designed with C701 tile at the leading edge of the ramp.
Sloped entries must extend to a depth between 24 inches minimum and 30 inches maximum below static water level. This depth is necessary for individuals using the sloped entry to become buoyant. Where the sloped entry has a running slope greater than 1:20 (5%), a landing at both the top and bottom of the ramp is required. At least one landing must be located between 24 inches and 30 inches below the static water level. Landings must be a minimum of 36 inches in width and 60 inches in length. The sloped entry may be a maximum of 30 feet at 1:12 (8.33%) slope before an intermediate landing is required. Adding a solid wall on the side closest to the water can enhance safety.
Sloped entries must have handrails on both sides regardless of the slope. Handrail extensions are required at the top landing but not at the bottom. The clear width between handrails must be between 33 and 38 inches. The handrail height must be between 34 and 38 inches to the top of the gripping surface. This provision does not require the handrails to be below the static water level, which could be considered an underwater obstruction. No minimum width is required between handrails provided on sloped entries that serve wave action pools, leisure rivers, sand bottom pools, and other pools where people can enter only in one place. Handrails are required to comply with ADAAG provisions (diameter, non-rotating, and height). For pools with a coping that protrudes beyond the face of the pool wall (bullnose, etc.), the dimension from the pool wall to the handrail must be adjusted to allow a minimum of 1.5 inches of clearance between the handrail and the coping at the point where the handrail slopes down across the pool coping.
Texas accessibility standards require all grating located in walking surfaces or along accessible routes to be perpendicular to the dominant direction of travel (i.e. parallel grating).
CURVED RAMPS ARE NOT COMPLIANT AS PRIMARY MEANS OF ADA ACCESS, UNLESS THE INNER RADIUS OF CURVATURE IS GREATER THAN 30 FEET:
The code limits cross-slope of a ramp to 2%, and offers the following advisory: Advisory 405.3 Cross Slope. Cross slope is the slope of the surface perpendicular to the direction of travel. Cross slope is measured the same way as slope is measured (i.e., the rise over the run).
The scoping and technical requirements on www.access-board.gov provide the following under section 4.8 Ramps: Curved ramps, while not specifically addressed by ADAAG, are not considered suitable for wheelchair traffic unless the radius of curvature is large enough. The curvature and slope typically result in an uneven surface that makes wheelchair maneuvering difficult because not all wheel’s rest on the surface. An inner radius of curvature over 30 feet is considered necessary in order to minimize the slope differential.
A transfer wall is a wall along an accessible route that allows a person to leave a mobility device and transfer onto the wall and then into a pool or spa.
Transfer walls must have at least one grab bar. Grab bars must be perpendicular to the pool wall and extend the full width of the wall so a person can use them for support into the water. The top of the gripping surface must be 4 to 6 inches above the wall to provide leverage to the person using the bars. If only one bar is provided, the clearance must be a minimum of 24 inches between the bars. The diameter of the grab bars must comply with ADAAG (diameter between 1.25 and 1.9 inches, nonabrasive, and non-rotating).
Clear deck space of 60 by 60 inches minimum, with a slope of not more than 1:48, must be provided at the base of a transfer wall. This will allow persons using a wheelchair to turnaround and access the wall, depending on the side they can best use to transfer. If there is one grab bar on a transfer wall, the clear deck space must be centered on the one grab bar. That allows enough space for a transfer on either side of the bar. If two bras are provided, the clear deck space must be centered on the 24-inch clearance between the two bars.
The transfer wall height must be 16 inches minimum to 19 inches maximum, measured from the deck.
Width and Length
Transfer walls must be a minimum of 12 inches wide to a maximum of 16 inches wide. This provides enough space for a person to sit comfortably on the surface of the wall and pivot to access the water. The wall must be a minimum of 60 inches long and must be centered on the clear deck space. Additional length will provide increased space and options for transferring.
Since people using transfer walls are in bathing suits, their skin may be in contact with the wall. To prevent injuries, the wall surface must have rounded edges and not be sharp.
A transfer system consists of a transfer platform and a series of transfer steps that descend into the water. Users need to transfer from their wheelchair or mobility device to the transfer platform and continue transferring into the pool water, step by step, bumping their way in or out of the pool.
Each transfer system must have a platform on the deck surface so users can maneuver on and off the system from their mobility device or wheelchair. Platforms must be a minimum of 19 inches deep by 24 inches wide. That provides enough room for a person transferring to maintain balance and provides enough space to maneuver on top of it.
Transfer platforms must be between 16 and 19 inches high, measured from the deck.
The base of the transfer platform must have a clear deck space adjacent to it that is 60 by 60 inches minimum with a slope no steeper than 1:48 so a person using a wheelchair can turn and maneuver into transfer position. The space must be centered along the 24-inch minimum unobstructed side of the transfer platform. A level, unobstructed space will help a person transferring from a mobility device.
The maximum height of transfer steps is 8 inches, although shorter heights are recommended. Each transfer step must have a tread depth of 14 inches minimum to 17 inches maximum and a minimum tread width of 24 inches. The steps must extend into the water a minimum of 18 inches below the static water level.
The surface of the transfer platform and steps must not be sharp and must have rounded edges to prevent injuries.
A grab bar must be provided on at least one side of each step and on the transfer platform, or as a continuous grab bar serving each step and the platform. The bar must not obstruct transfer onto the platform. If a grab bar is provided on each step, the top of the gripping surface must be 4 inches minimum to 6 inches maximum above each step. If a continuous bar is provided, the top of the gripping surface must be 4 inches minimum to 6 inches maximum above each step nosing. Grab bars on transfer systems must comply with ADAAG (diameter between 1.25 and 1.9 inches, nonabrasive, and non-rotating).
Accessible pool stairs are designed to aid with balance and support from a standing position when moving from the pool deck into the water and out. ADAAG provisions for stairs include the requirement that all steps have uniform riser heights and uniform tread widths of not less than 11 inches, measured from riser to riser. Additionally, open risers are not permitted. Other stairs or steps provided in the pool are not required to meet these guidelines.
Pool stairs must have handrails with a minimum width between the rails of 20 inches and a maximum of 24 inches. The 20- to 24-inch width for the accessible pool stairs is intended to provide support for individuals with disabilities who are ambulatory. Handrail extensions are required on the top landing of the stairs but are not required at the bottom landing. Handrails on pool stairs must comply with ADAAG provisions. The top of the handrail gripping surface must be a minimum of 34 inches and a maximum of 38 inches above the stair nosing. If handrails are mounted on walls, the clear space between the handrail and wall must be 1.5 inches. For pools with a coping that protrudes beyond the face of the pool wall (bullnose, etc.), the dimension from the pool wall to the handrail must be adjusted to allow a minimum of 1.5 inches of clearance between the handrail and the coping at the point where the handrail slopes down across the pool coping.
