Safety Alert – Aluminium Alloy Diving Gas Cylinders

The Health and Safety Executive (HSE) have issued a Safety Alert for cylinders manufactured from aluminium alloys HE30/AA6082 and AA6351 and used primarily for gases for underwater breathing apparatus.

HSE also intend to publish the Safety Alert on a diving e-bulletin.

HSE advise that there have been several recent catastrophic failures of aluminium cylinders used primarily to contain gases for underwater breathing apparatus and manufactured from aluminium alloys HE30/AA6082 and AA6351. Cylinders manufactured from these alloys are known to be susceptible to sustained load cracking (SLC). These cylinders should only be used if they have undergone thorough visual inspection and testing with an eddy-current device by a competent inspector.
