Final answer:

In the event of a chemical spill in a lab, the first course of action is to notify the lab instructor or TA.

Explanation:

If a chemical is spilled in the lab, the first action you should take is to notify the lab instructor or teaching assistant (TA). It is critical to get the assistance of someone trained in handling such emergencies. Attempts to neutralize or dilute the spill yourself can be dangerous as some chemicals react violently with common neutralizing substances like baking soda, or with diluents like water.

For instance, adding water to acid should be strictly avoided since the correct procedure is to add acid to water to prevent a potentially violent reaction. Your instructor will likely know the appropriate steps to take and has the authority to guide you and ensure that everyone’s safety is prioritized.

After notifying the appropriate authority in the laboratory, follow their instructions. They may direct you to surround the spill with absorbent materials to prevent spreading or use specific neutralizers if applicable. Always avoid exposing the chemical to flames or sparks, especially if it’s flammable, and evacuate the area if instructed to do so. Staying calm and following established safety procedures is essential in any laboratory emergency.
