If a concentrate labeled DANGER/POISON is swallowed, what amount could potentially be fatal for the average person?

The concentration of a substance labeled DANGER/POISON indicates a high level of toxicity, meaning even a small amount could pose a serious health threat. In toxicology, substances that fall under the category of poisons can have lethal effects with minimal exposure.

Swallowing a taste to a teaspoon of such a concentrate can often lead to severe consequences, including fatal outcomes, especially if the toxic nature of the compound is strong enough. This quantity may vary depending on individual tolerance levels; however, it is widely acknowledged that even minuscule amounts of highly toxic substances can be lethal.

In contrast, larger quantities, such as half a cup or one ounce, are generally well beyond what is necessary to deliver a fatal dose, especially for concentrates designated as poisons. Therefore, the selected option reflects the extremely dangerous nature of substances marked as DANGER/POISON, where even a small quantity could potentially result in severe toxicity or death.
