One can handle fragile materials properly by treating them with care. For example when transporting fragile materials such as glass or dynamite one should wrap them in a protective layer.
Carefully
Because many (if not most) lab materials can be very dangerous. Strong acids and bases like sulfuric acid and ammonia can seriously harm the skin/lungs/eyes etc if not handled properly. If one does not know how to properly handle something that produces high heat (eg bunsen burner) or high cold (eg liquid nitrogen) one could be seriously injured, lose fingers, or even die.

You can touch and handle butterflies if you do it properly. There are butterfly tagging programs in which butterflies are caught, tags are placed on their wings, and they are released. Some tagged butterflies fly hundreds of miles before being recaptured, even though their wings were touched. If enough scales are rubbed off the wings by improper handling, they can be rendered flightless, but they are not nearly as fragile of creatures as one might think.
All vacuum materials are safe and non-carcinogenic as long as they are properly maintained and serviced by authorized service centers.
