Raffles
You might need to take some ID with you, plus a hard hat, safety specs and some sort of decontam coverall.
You may also need to be conversant with the stn's policy regarding H&S, EO, Diversity management, Food Act, COSSH, IIP, FOI Act, use of cameras, laptops and mobiles, OOB areas, clean area practices, NDT testing areas, noise related hazards, Fire regulations, Evacuation procedures, First Aid, Mess Rules, lost children's tent, and the paying of compliments etc, etc.
However, I am sure you will be fully briefed on this, which should take up most of your alloted visit time.
Enjoy !!
