An emergency situation that may not allow workers to follow normal evacuation procedures is a fire in a tall building such as a skyscraper.
Step-by-step explanation:
An emergency situation that may not allow workers to follow normal evacuation procedures is a fire in a tall building such as a skyscraper. In such a situation, the stairs or elevators may be blocked or unsafe to use, making the usual evacuation procedures ineffective. In this case, workers may need to use alternative methods such as rappelling down the building using ropes or waiting for emergency rescue teams to reach them.
