if a laboratory fire erupts, immediately group of answer choices run for the fire extinguisher. throw water on the fire. notify your instructor open the windows
The Correct Answer and Explanation is :
In the event of a laboratory fire, the correct course of action is to notify your instructor immediately.
Explanation:
Laboratory fires pose serious risks due to the presence of flammable chemicals and sensitive equipment, so responding correctly is critical for safety. While it might seem intuitive to grab a fire extinguisher or attempt to extinguish the fire yourself, these actions can be dangerous if done improperly or without understanding the fire’s source.
Here’s why notifying the instructor is the first step:
- The instructor is trained: Instructors are trained in handling lab emergencies and can assess the situation to determine the most appropriate action. They know the layout, the location of safety equipment, and the types of chemicals being used, which will influence their decisions.
- Safety protocols: Labs are equipped with safety protocols designed to minimize harm. The instructor will initiate these protocols, which may include ordering an evacuation, using a specific fire extinguisher, or activating a fire alarm.
- Varied fire types: Not all fires can be extinguished with a single approach. For example, a Class B fire involving flammable liquids requires a different approach than a Class A fire involving solid combustibles. Incorrectly using water on chemical or electrical fires can worsen the situation, leading to severe consequences like spreading the fire or causing electrical hazards.
- Personal safety: Fires can escalate rapidly, and without proper protective gear or training, an individual may suffer burns, smoke inhalation, or exposure to toxic fumes. By notifying the instructor, you prioritize both your safety and the safety of others.
In summary, notifying the instructor allows for a controlled, informed response to the fire, reducing the risk of injury or further escalation. It’s a fundamental principle of lab safety designed to protect everyone in the vicinity.
