The minimum clearance width for a door is…
32”
Horizontal grab bars at the side wall of an accessible toilet must ne mounted at:
33”-36” AFF
What is the minimum clear floor space required for side transfer for an accessible (barrier free) shower?
36”x48”
As measured from nosing, a handrail for barrier-free design must have a height of…
34”-38”
What is the correct dimension for the top of rim height of an accessible urinal?
17”
What is the requirement of space needed on the push and pull side of a door?
minimum of 18” on pull side and 12” on push side is required
Which solutions can interior designers incorporate for good bathroom design to address the loss of visual acuity due to aging?
Increased and flexible general lighting
Bottom extension at stairs:
bottom of stair flight: handrails shall extend at the slope of the stair flight for a horizontal distance equal to one stair tread depth beyond the bottom trad nosing.
Shall return to wall, guard, or landing surface
Controls for all ADA wall mounted accessiories must be located how many inches AFF for a side reach?
15”-48”
How hight should acoustic panels be?
at least 60”
“inclusive” design, sometimes referred to as “universal” design, is characterized by what main feature?
Inclusive design addresses the needs of the broadest range of individuals
Accessible mirrors over a lavatory must be mounted with the edge of the reflective surface no higher than how many inches AFF?
40”
Characteristics of circular accessible handrails
must have outside diameter of 1 1/4” minimum and 2” max
1 1/2” clearance from the wall is minimum. it can be more
According to the ADA section 702 “fire alarm safety”, audible alarms have a max. dB level requirement. True or False
True
When designing a stairway, which items must be designed to specific requirements to be accessible?
nosing and handrail
If a accessible route is less than 60” wide, when must a 60”x 60” passing space be provided?
Accessible routes and other clearances are based upon basic dimensional requirements for wheelchairs. If an accessible route is less than 60 in (1525 mm) wide, then passing spaces at least 60″ x 60″ (1525 mm x 1525 mm) must be provided at intervals not to exceed 200 ft
What are the require tread and riser height for stairs?
Riser: 4” minimum and 7” Maximum
Tread: 11” deep minimum, there is no maximum
What is static load?
The maximum amount of non-moving weight a piece of equipment can bear.
For example, it would be applied to furniture, handrails, grab bars, and toilets.
What is dynamic load?
Designing for safety, dynamic load accommodates the weight of a patient in falling motion.
Dynamic load must always exceed the static load.
As a rule of thumb, a falling human is double their weight. If we are designing for a bariatric population of up to 900 pounds, anything we specify has to withstand an impact weight—or dynamic load—of 1800 pounds.
What is the maximum rise a ramp can be? What rise is the most comfortable?
1:12 Max
1:20 is the most comfortable
What is the minimum clear width for a ramp and what size should the landings be
36” wide ramp run
60” landing
