If you go and a demon or spirit does attach themselves to you will Zak come to us and help get rid of it or do a cleanse before we leave? Something so doesn't go with us..

No, and they make you sign waivers releasing them from any liability. Zak also is rarely there

Enter at your own risk.

You sign a waiver, relinquishing them of any liabilities. You on your own. They say don't touch stuff

I would recommend doing a cleansing after or do some measures to protect yourself going in. But he does have signs and you sign a waiver as well.

It's to my understanding that you sign a waiver of liability, and Zak is almost never there. However I also understand that many objects that are haunted want attention so the best place for them is in the Museum, it's very unlikely that something that's content would attach itself to you if it's getting what it wants at the museum.

I don't know if zac will cleanse bc he goes out and does his show but someone is always there to help take out spirt or if u faint someone will be there to help

No
