Final answer:
ADA guidelines dictate that hand dryers should be positioned no higher than 40 inches for forward reach and 48 inches for side reach, while trash receptacles should also have their opening within the 48 inches reach range to be accessible for individuals with disabilities.
Step-by-step explanation:
The Americans with Disabilities Act (ADA) provides guidelines for the height of hand dryers and trash receptacles to make them accessible to all individuals, including those with disabilities. For hand dryers, they must be positioned at a height where the operable parts are within reach for all users, typically not higher than 40 inches (101.6 cm) for forward reach and no higher than 48 inches (121.9 cm) for side reach from the floor. Similarly, trash receptacles should also comply with reach ranges by having the opening located no higher than 48 inches (121.9 cm) and without any protruding parts that can impede access for a person in a wheelchair.
It's important to consult with the latest ADA standards or an accessibility professional when designing or renovating a public restroom to ensure compliance with ADA guidelines. These regulations help create inclusive spaces where everyone has access to facilities such as hand dryers and trash bins without unnecessary difficulty.
