Which item is listed as an acid threat?

Explanation:
Acids are substances with a pH below 7 that can irritate or damage tissue, and in security screening we focus on liquids that could be misused to cause harm. Lemon and lime juice contain citric acid, which makes them acidic and capable of causing irritation if misused in a confined space like an aircraft cabin. This is why they’re identified as an acid threat. Water is neutral and soap is not acidic, so they don’t fit this category. Vinegar is acidic too, but the example here highlights citrus juice as a clear acid threat due to its acidic nature alongside being a common travel item.
