Which of the following is a characteristic of low-order damage?

The characteristic of low-order damage is exemplified by a slow pressure rise, accompanied by pushing and bulging types of damage. This type of damage typically occurs in scenarios where the explosive force is not extremely violent, leading to more gradual displacement of materials. As a result, structures might experience deformation or bending rather than catastrophic or immediate destruction.

In low-order explosive events, the pressure increases gradually enough that materials within the structure may bulge outward instead of shattering or pulverizing. This contrasts with high-order damage, which is characterized by rapid pressure increases leading to more abrupt, severe destruction. The slow pressure rise allows for an initial warning or indication of danger, providing a stark difference in the progression of damage compared to more violent explosive events.

In this context, the option that describes slow pressure rise aligns perfectly with the typical outcomes from low-order explosions, making it the correct answer for identifying the characteristics of this type of damage.
