How often must scuba tanks be hydrostatically tested according to regulations?

• A. Every three years
• B. Every five years
• C. Every ten years
• D. Every year

Answer: (B)

Scuba tanks must be hydrostatically tested every five years to ensure their safety and integrity for use. This testing checks for any weaknesses or cracks in the tank material that could lead to catastrophic failure while under pressure. The five-year interval is based on industry standards that balance safety with practicality, allowing divers to maintain their tanks without excessive financial or logistical burdens. Regular testing within this timeframe helps to ensure diving safety, as a properly maintained tank is critical for preventing accidents during diving activities. The options suggesting shorter intervals, like every three years or annually, aren't necessary given that a five-year cycle is established as adequate for maintaining tank safety. Meanwhile, the ten-year option is too infrequent, given that the potential risks of delayed inspections could compromise diver safety. Therefore, a five-year testing requirement is the most rational and widely accepted approach in the scuba diving community.
