Prior to undertaking this training course, staff and post-graduates are required to successfully complete the following training course: Using Liquid Nitrogen Safely Within Universities.

In order to be allowed to participate in the practical workshop your delegates must bring and wear appropriate Personal Protective Equipment (PPE):

• Steel toe capped safety boots, with non-slip soles, specific for use with cryogenic liquids. The footwear should afford the user sufficient protection against spillage. Should the boots have tongues, these should be sewn in to prevent liquid ingress.

• To prevent liquid ingress into safety boots, ensure trousers do not have cuffs.

• Safety glasses or a face shield to protect against pressure or splashes when decanting liquid nitrogen.

• Gloves appropriate for cryogenic use.

Our trainer may permit delegates not wearing the correct PPE to view the practical workshop, but they will not be permitted to actively participate in it.
