Helmet Maintenance

Cylinder Withdrawal

In July 2017, WorkSafe New Zealand issued a Safety Alert informing the industry of the withdrawal of design approvals for cylinders manufactured from aluminium alloy 6351.  The withdrawal of approval follows two serious harm incidents due to catastrophic failures of cylinders manufactured with the 6351 alloy.
