Hazardous materials cylinders can now be checked with ultrasound, not just visual inspection

The US Department of Transportation wants to let companies use ultrasound to check hazardous materials cylinders. This means these cylinders will need to be re-checked less often, saving companies time and money.

For decades, the rules for checking these cylinders were based on older visual inspection methods. Using ultrasound is a modern testing technology that can spot problems more accurately. This change means companies can use better technology and reduce how often they have to take cylinders out of service for checks.
