Can safari be used as a kiosk?

I'm trying to lock down an iMac 2014 with a password so that my customers can not leave the web browser app e.g safari, and only the websites that i allow may be accsessed. Can safari do this or will i need another app, it would be nice to display a custom welcome splash screen which would be shown until someone moves the mouse or clicks start. Also to have it go back to that screen after a few minutes of inactivity. I also can run windows 10 in VMware fusion if this helps as a last resort. Need some advice thanks
