Final answer:
An emergency situation that may hinder normal evacuation procedures includes fire in a high-rise building, earthquake affecting the structural integrity of the building, and chemical or biological hazards.
Step-by-step explanation:
An emergency situation that may not allow workers to follow normal evacuation procedures is a fire in a high-rise building. In such a scenario, the elevators may be non-functional or unsafe to use, making the standard evacuation routes impassable. The workers would need to evacuate using the staircases and follow the designated fire escape plans.
Another example is an earthquake, where the structural integrity of the building could be compromised, leading to the collapse of staircases or exits. In this case, workers may need to find alternative escape routes or shelter in place until rescue teams arrive.
Lastly, in a chemical or biological hazard situation, workers may need to stay in sealed areas or take shelter in designated safe rooms instead of evacuating immediately to minimize exposure to harmful substances or pathogens.
