Blasters must be protected with an approved blast helmet. The Nova 2000 is actually approved to AS1716-2003 - Licence No: SMKH21723.
For health and safety reasons, every Blaster should have their own helmet. Before purchasing any Blast Helmet, ensure it is approved - if not your liabilities may be at risk. Nova 2000 Helmets are robust, lightweight, quiet, cool, safe and comfortable.
