Keep operation under appropriate adult control and follow the manufacturer's supervision and age guidance. A silent appliance or a covered opening should not be treated as a substitute for controlling access to its switch.
What the observation tells you
Children may confuse the air button with another sink fitting or feed an object that is not food. Explain which control operates the disposer and keep the correct protective accessories in place. Do not demonstrate the mechanism by placing hands or utensils inside.
A useful next step
When cleaning or investigating a fault, isolate the appliance and tell everyone that it must remain unused. Store loose accessories where they cannot be mistaken for toys.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
