Which term refers to changing the shape of an object in emergency situations?

The term that specifically refers to changing the shape of an object in emergency situations is "deform." When an object is subjected to external forces, such as during a vehicle collision or when pressure is applied for rescue efforts, it can become deformed. Deformation encompasses not only bending or twisting but also any alteration in shape that affects the original form of the object.

In the context of vehicle rescue, understanding deformation is crucial for rescuers to assess the structural integrity of a vehicle and to determine the best methods for extricating occupants. This is particularly relevant in understanding how materials respond during incidents and the potential risks involved when dealing with compromised structures.

While terms like "alter" and "distort" can imply changes in shape, they do not carry the specific connotation of structural changes that "deform" implies, making "deform" the most accurate choice in this scenario.
