People do not necessarily act rationally in emergency situations. That is why it's important to design things in a way that's obvious and avoids unexpected obstacles (e.g., the door doesn't open anymore and you need to use a secondary handle). For example, sliding doors usually have clearly marked text on them saying "in event of power loss, push to open".
