When is nondestructive testing most likely performed on aerial apparatus?

Nondestructive testing (NDT) is crucial for ensuring the structural integrity and safety of aerial apparatus, especially after any incidents or accidents. Conducting NDT after accidents allows for a thorough inspection without causing further damage to the equipment. This process is essential to identify any potential weaknesses or structural defects that may have arisen due to the stresses endured during the incident.

Regular intervals of testing, such as bi-monthly or annually, are important for routine maintenance, but they don't account for the immediate need for inspection after a significant event like an accident. Similarly, performing tests after every use might be logistically challenging and unnecessary for maintaining safety, as it would overwhelm resources and may not provide meaningful results outside of an incident context. Thus, performing nondestructive testing specifically after accidents is crucial for ensuring the ongoing reliability and safety of aerial apparatus for operational readiness.
