When concentrated sulfuric acid is spilled on the arm, the primary and most critical action is to rinse the affected area with water for at least 15 minutes. This action is essential because water helps to dilute the acid, minimizes further skin damage, and cleanses the area to prevent additional injury. Sulfuric acid can cause severe burns and damage to the skin; therefore, prompt and thorough rinsing is vital to reduce its corrosive effects.

Using just soap may not effectively neutralize the acid or remove it from the skin, which is why direct and copious rinsing with water is emphasized. Other treatments, such as applying sodium hydroxide, could potentially result in chemical reactions that may worsen the situation rather than alleviate it. Seeking medical attention is critically important, but the immediate response in the event of chemical exposure is always to flush the area with water to mitigate injuries from the corrosive substance.
