What safety consideration should be taken into account for displays?

When considering safety for displays, the idea of not using electricity may stem from concerns about the risks associated with electrical equipment in certain settings. Not using electricity can eliminate potential hazards such as electrical shocks, short circuits, and the risk of electrical fires, particularly in environments like floriculture displays, where water and moisture can be present. By avoiding electrical equipment altogether, one removes the complexities and safety issues associated with handling electrical devices and ensures a safer setup for both the display and the attendees interacting with it.

The other considerations, while relevant to safety, still involve using electricity at some level or depend on electrical devices. Thus, the emphasis on completely avoiding electricity stands out as a proactive safety measure in this context.
