Question

marie: i passed out because of the blast. what happened after i was pulled out of the lab?
a) trigger alarm and break the circuit
b) extinguish the fire
c) close the fume hood
d) evacuate the building

Explanation:

In case of a blast in a lab, the most immediate and crucial action is to ensure the safety of all people in the building. Evacuating the building helps in getting everyone away from potential further hazards like fires spreading, chemical leaks etc. Triggering an alarm and breaking the circuit (a) might be part of the initial response but not the most important next - step after pulling someone out. Extinguishing the fire (b) is important but only if one is trained and it is safe to do so immediately. Closing the fume hood (c) is a minor action compared to evacuating the whole building.

Answer:

d) Evacuate the building
