When the Americans With Disabilities Act was first passed in , certain requirements for elevators were outlined, such as the installation of raised buttons, braille signs, and audible signals. The act ensured that someone with a disability would have enough time to get inside, stipulating that elevator doors must remain fully open for at least three seconds and thereby preventing the button from cutting that time short.
Some elevator manufacturers took it one step further by deactivating the button entirely. Only firefighters are able to close elevator doors manually through the use of a key. It's important to note that there are exceptions to this rule, though. As the New York Daily News noted , New York City elevators are required by law to have working 'close door' buttons, even though some operate on a long delay so long, in fact, that it calls the button's usefulness into question.
