Which statement about ADS inspections is true?

• A. Before and after every use.
• B. Before and after every use, every 6 months, and stamped with month and year.
• C. Before every use and every 6 months
• D. Inspect on a yearly basis.

Answer: (B)

Regular maintenance checks on ADS are done by combining immediate safety checks with scheduled maintenance and solid recordkeeping. Inspecting before each use verifies that all functions work and there are no obvious defects, while inspecting after use catches issues that may have developed during operation. In addition, a formal check every six months ensures a deeper evaluation of wear, corrosion, or degradation that a quick pre/post-use check might miss. Stamping the inspection with the month and year creates a traceable maintenance record, showing exactly when the last service was done and helping plan the next due date. The other options miss at least one of these elements, such as post-use inspection, the six-month interval, or the date stamp, or they rely on only yearly checks, which aren’t sufficient for safety-critical equipment.
