Which statements about responding to lab emergencies are true?

• A. Stay calm
• B. Know where the stairwells are
• C. If possible turn off lab equipment before leaving during a fire alarm
• D. All of the above

Answer: (D)

In lab emergencies, staying calm helps you think clearly and follow the emergency plan instead of panicking. Knowing where the stairwells are ensures you can evacuate quickly and safely without getting lost or blocked paths. If you can do so safely, turning off lab equipment before leaving reduces the risk of ongoing fires, explosions, or chemical releases. Taken together, these practices address personal safety, efficient evacuation, and hazard minimization, so all of these statements describe appropriate responses to a lab fire alarm.
