In cases of liquid contamination, what immediate action should be taken?

In cases of liquid contamination, the most appropriate immediate action is to blot the agent off of exposed skin. This approach helps to remove harmful substances from the skin's surface before they can cause further irritation or absorption into the body. Quickly addressing liquid contamination is crucial as it minimizes potential health risks associated with exposure to hazardous chemicals or toxins.

Blotting, rather than rubbing, is emphasized to avoid spreading the contaminant over a wider area of skin or pushing it deeper into the tissue. This method is especially important when dealing with substances that may cause chemical burns, irritation, or other adverse effects.

Other options such as covering the area, waiting for the agent to dry, or applying lotion are not recommended in a situation involving liquid contamination. Covering the area could trap the contaminant against the skin, waiting for it to dry might allow for greater skin absorption, and applying lotion could further irritate the skin or mask the presence of the contaminant, making a timely and effective response much more difficult.
