What are you supposed to do if you get stuck in a lift and you don't have your laptop (or zero cell signal for example)?

In the US at least, the button actually has to connect you to emergency personnel. It also has to be in a highly accessible location which is why it’s at the bottom of the panel generally. The US is kind of a stickler for accessibility and safety in building codes, despite the country’s reputation.

This is an older post from the UK so I don’t know if the button was required to be connected and something was wrong or if they really can leave it as a simple alarm like that.

I, personally, would take the opportunity to have an undisturbed nap. The thought of having no notifications and a great excuse for why I wasn’t answering sounds lovely today.

I can't see the lift obviously but in the movies they punch out the ceiling and climb out
