All of these machines have clearly visible safety warning signs displayed on the areas where heat is the most concentrated. The bright red color of the warning signs helps children to notice them as well. In addition, many of these machines feature visual safety cues that help parents manage their operation. These include ways to control the voltage, a visual volt measure display, and a fuse controller. Sturdy feet on the bottoms keep the machine in place while in use, preventing it from toppling over or spilling. The Clevr Commercial Cotton Candy Machine even has an automatic safety feature that prevents the machine from turning on unless the pot is fully latched on.
