Question: If you spill a chemical on yourself in lab, immediately rinse with plenty of water.

Option 1: True
- Rationale: In laboratory safety protocols, the first response to a chemical spill on the skin is to flush the affected area with copious amounts of water as soon as possible. The goal is to dilute and remove the chemical to minimize skin absorption and irritation. Safety showers or eyewash stations are designed for this purpose and should be used for a sustained period, typically at least 15 minutes, while removing contaminated clothing if needed.

Option 2: False
- Rationale: This statement would be incorrect because delaying rinsing or using a minimal rinse would increase the risk of chemical burns, irritation, or systemic absorption. Some chemicals can be highly caustic or reactive, and time is critical in reducing potential harm. While there are specialized procedures for certain substances (e.g., acids, bases, or oxidizers) that may call for specific steps afterward, the initial and most crucial action is immediate water rinse.

Summary of reasoning: The recommended immediate response to a skin splash in a lab is to begin thorough rinsing with water right away, followed by appropriate decontamination steps. Delaying or avoiding rinsing contradicts established safety guidelines and increases risk to the individual.
