My elevator control panel includes these four “special” buttons:

• “Call Cancel”
• A graphic of a fire fighter’s helmet
• “Alarm”
• A graphic of a telephone

In an emergency, which should I use?  We can probably rule out the first, but the other three all sound like good choices.  I’d likely just press them all at once, so why bother installing three separate choices?

Surely the panel designers could tell us when each button is meant to be used individually, but unfortunately the elevator-riding public has not received training on these situations.  We know how to select our destination floor, but after that we really stop caring about elevator control panel operations.
