Answer: (B)

A * sign on a gas cylinder indicates that the tank has been approved for retesting and requires this retest every 10 years. This marking signifies that the cylinder has been inspected and certified for ongoing safety and efficiency, which is crucial for ensuring proper handling and use in medical settings.

The retesting is part of a quality assurance process, ensuring that the cylinder can continue to safely contain gases without leaks or failures. Proper adherence to this marking helps maintain safety standards in environments where medical gases are utilized, such as hospitals and clinics. Recognizing such indicators is essential for healthcare professionals to ensure that all medical equipment is compliant with safety regulations, thereby preventing accidents or incidents related to gas cylinder mishandling or failure.
