What type of inspection do scuba cylinders require every year?

Scuba cylinders require a visual inspection every year as part of their maintenance to ensure safety and functionality. This visual inspection is critical as it helps detect any signs of damage, corrosion, or other issues that could compromise the integrity of the cylinder. During this inspection, divers or technicians closely examine the external and often parts of the interior of the cylinder for wear, dirt, or any signs of algae or moisture that may indicate potential problems.

It's important to conduct this inspection annually, as it ensures that any potential hazards are caught early, helping to prevent accidents or failures during use. This proactive approach to cylinder maintenance is a key component of safe diving practices.

While pressure inspections may be conducted at longer intervals to test the cylinder's ability to hold air under pressure, the annual visual inspection is crucial in identifying immediate risks and maintaining overall safety for divers.
