1. Protect Yourself First: Before assisting a child, ensure you are wearing appropriate protective gear such as gloves and masks. 2. Avoid Contact with Contamination: Carefully cut away the clothing to avoid dragging it over the child's head or other parts of the body. 3. Bag the Contaminated Clothing: Place the contaminated items in a sealed plastic bag to prevent further spread of contaminants. 4. Decontaminate the Skin: Gently wash the affected skin areas with soap and water to remove residual substances.
