What household items that can knock you out?

Several common household items can pose a risk of causing unconsciousness if misused or ingested. For example, carbon monoxide from gas appliances can lead to poisoning and loss of consciousness. Additionally, certain cleaning products contain toxic chemicals that, if inhaled or ingested in large quantities, can be harmful. Lastly, excessive alcohol consumption can lead to unconsciousness, often found in households where alcohol is present. Always ensure proper ventilation and safety precautions when using household items.
