In a laboratory setting, what immediate action should be taken if chemicals are spilled on the skin?

When chemicals are spilled on the skin, the most important immediate action is to wash the affected area with plenty of water. This helps to dilute and remove the chemical from the skin, which can prevent further irritation, burns, or absorption into the body. Promptly rinsing the area with water for at least 15 minutes is critical to minimize the potential harmful effects of the chemical exposure.

While covering the area with bandages may seem protective, it can actually trap the chemical against the skin, exacerbating the injury. Delaying medical assistance for half an hour is risky as some reactions to chemical exposure can worsen over time. Similarly, applying creams or ointments could interfere with the ability to wash away the chemical effectively and may cause additional skin reactions. Immediate decontamination with water is essential for safety in such scenarios.
