Final answer:
It is true that an emergency escape and rescue opening should never be placed under a porch or deck to ensure unobstructed access for safe exit or rescue during an emergency.
Step-by-step explanation:
The statement is true; under no circumstances should an emergency escape and rescue opening be located under a porch or deck.
According to building codes and safety regulations, emergency openings such as windows or doors, are required to provide an unobstructed path for exit or to allow rescue operations in case of an emergency.
Placing an emergency escape under a porch or deck could impede these efforts due to potential blockages or difficulties accessing the opening.
Therefore, safety standards mandate that such openings be directly accessible and not located beneath structures that could complicate emergency egress or ingress.
