What does an asterisk (*) next to the date indicate for specific equipment?

The asterisk indicates that the equipment requires a specific type of inspection, which in this case is a 10-year Department of Transportation (DOT) inspection. This means that after installation or initial certification, equipment marked with an asterisk must undergo this periodic inspection to ensure it remains compliant with safety regulations and operational standards.

Periodic inspections, including the 10-year DOT inspection, are crucial because they help to assess the structural integrity and functionality of the equipment used in medical gas storage. Regular assessments help prevent potential failures or accidents that could arise from worn-out or improperly maintained equipment. Thus, an asterisk serves as a reminder of this regulatory compliance requirement, emphasizing the importance of adhering to safety protocols in medical gas handling and storage.
