Hard Hat Exemption
You may be exempt from the requirements to wear a hard hat, however, you will be required to obtain a “Certificate of Exemption”.
Basically, if your head meets the Australian/New Zealand Standard for head protection you do not need a hard hat.
Contact the Safety Coordinator to schedule you for testing at the earliest possible time.

If you don’t feel qualified, do not despair...
Although not as attractive as your hair-do, your hard hat does meet all of the above requirements.
