A. Notify your instructorExplanation
In the event of a laboratory fire, it is crucial to immediately notify your instructor. This is because the instructor is responsible for ensuring the safety of everyone in the laboratory and will be able to take appropriate action to control the situation. Running for the fire extinguisher may be necessary later on, but notifying the instructor should be the first step to ensure the safety of all individuals present. Throwing water on the fire may not be effective, as it could potentially spread the fire or cause other hazards. Opening the windows may help to ventilate the area, but it should not be the immediate response to a fire.Rate this question:
