Questions: If a laboratory fire erupts, immediately - open the windows. - throw water on the fire. - notify your instructor. - run for the fire extinguisher.

Solution Steps

When a laboratory fire erupts, the priority is to ensure safety and follow proper emergency procedures. Let's analyze each option:

1. Open the windows: This might not be the best immediate action as it could potentially feed the fire with more oxygen, making it worse.

2. Throw water on the fire: This is not always appropriate, especially if the fire involves chemicals or electrical equipment, as water can react with certain substances or conduct electricity.

3. Notify your instructor: This is a crucial step because the instructor is trained to handle emergencies and can guide the appropriate response.

4. Run for the fire extinguisher: This is a proactive step to control the fire, but it should be done only if it is safe to do so and you are trained in using a fire extinguisher.

The best immediate action in the event of a laboratory fire is to notify someone who is trained to handle such situations. This ensures that the correct procedures are followed and that help is on the way.
