Final answer:
Compressed gas containers are subject to periodic testing and examination. This is to detect potential flaws and maintain the best performance of the containers. Regular maintenance is important, whereas replacement or cleaning normally arises from identified problems during examination.
Step-by-step explanation:
Compressed gas containers, unless they are disposable, are subject to periodic testing and examination. Regular examination of these containers is critical to detect any potential flaws or weaknesses in the structure that could lead to failures or dangerous situations. For example, defects such as cracks, rust, or other types of damage can significantly decrease the containers performance and running conditions. Therefore, regular maintenance is also important to ensure that the containers are kept in the best possible condition. It is not generally considered part of routine testing to replace or clean the containers unless a problem is identified during the examination.
