As a visitor, extra care must be exercised to avoid damaging collections.  Always maintain a reasonable distance from exhibits.  If you are too close, a simple gesture like pointing or waving could damage fragile displays if you accidentally touch them.  If you must, just keep your arms folded or clasp your hands behind your back while viewing.

Touching with your eyes isn’t limited to the primary object on display.  Consider that even display labels, pedestals, and encasements are also hands-off items.  Remember that these priceless collections are rare and originals and cannot be replaced when lost or damaged.  Some old, delicate collections such as oil paintings on canvass may be easily damaged by a mere touch of human hands which contain traces of sweat that is acidic.

There are instances however when visitors are invited to get a closer view of displays or to even touch them.  In this case, it is quite alright to do so.
