During a laboratory experiment, Juan accidentally catches his clothing on fire. His lab partner sees this and should:
- A.
Grab the fire extinguisher and spray Juan to put out the fire.
- B.
Tell Juan to run around screaming, "I'm on fire."
- C.
Use the fire blanket to smother the flames
- D.
Take Juan to the laboratory shower and pour water on him to put the fire out
Correct Answer
C. Use the fire blanket to smother the flamesExplanation
When a person's clothing catches fire, it is important to smother the flames to extinguish the fire. Using a fire blanket is the correct action to take in this situation as it can effectively smother the flames and prevent the fire from spreading further. Using a fire extinguisher or pouring water on the person can potentially worsen the situation by spreading the fire or causing burns. Running around screaming is not a helpful or effective response to a fire emergency.Rate this question:

(From Question 3) According to the HSE Laboratory Safety Agreement, what else should Juan's lab partner do?
- A.
Take Juan to the nurse
- B.
Call 911
- C.
Report the incident to the instructor
- D.
Instagram a picture of Juan with his arm on fire. #awesome
Correct Answer
C. Report the incident to the instructorExplanation
Juan's lab partner should report the incident to the instructor. This is important because the instructor needs to be informed about any accidents or incidents that occur in the lab. By reporting the incident, the instructor can take appropriate action to ensure Juan receives the necessary medical attention and that any necessary safety measures are implemented to prevent similar incidents in the future. It is not appropriate or safe to take Juan to the nurse or call 911 without informing the instructor first. Instagramming a picture of Juan with his arm on fire is not only insensitive but also a violation of lab safety protocols.Rate this question:

When heating chemicals in a test tube, you should point to the open end of the test tube:
- A.
Towards the sink
- B.
Towards the flame
- C.
Away from yourself and others
- D.
Towards the chemical containers
Correct Answer
C. Away from yourself and othersExplanation
When heating chemicals in a test tube, it is important to point the open end of the test tube away from yourself and others. This is because heating chemicals can cause them to react or release harmful fumes, and pointing the open end away from yourself and others ensures that any potential hazards are directed away from people. It is crucial to prioritize safety and minimize the risk of accidents or exposure to harmful substances.Rate this question:

When working with edible supplies (candy, food, etc.) in the laboratory, when are you allowed to consume (eat) them?
- A.
When the lab is over
- B.
When given permission to do so
- C.
In the middle of the lab
- D.

Correct Answer
B. When given permission to do soExplanation
In a laboratory setting, it is important to prioritize safety and follow the rules and regulations set in place. Consuming edible supplies can potentially contaminate the experiment or pose a health risk. Therefore, it is necessary to wait for permission from the appropriate authority before consuming them. This ensures that the consumption is done at the appropriate time and in a controlled manner, minimizing any potential risks or disruptions to the experiment.Rate this question:

Once the experiment is over, you should place/pure unused chemicals:
- A.
In the sink
- B.
In the trash
- C.
Back in the containers
- D.
In the location that the instructor states
Correct Answer
D. In the location that the instructor statesExplanation
It is important to place/pure unused chemicals in the location that the instructor states because the instructor is responsible for ensuring proper disposal or storage of chemicals. The instructor will have knowledge of the specific requirements for each chemical, such as whether it needs to be stored in a specific temperature or if it requires special disposal procedures. Following the instructor's instructions ensures the safety of everyone involved and prevents any potential harm or accidents that may occur from improper handling or disposal of chemicals.Rate this question:

In the laboratory, it is expected that your always:
- A.
Tie long hair back
- B.
Remove all dangling jewelry
- C.
Remove all jackets
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
In the laboratory, it is important to follow safety protocols to minimize the risk of accidents or contamination. Tying long hair back prevents it from getting caught in equipment or chemicals. Removing dangling jewelry prevents it from getting tangled or caught in machinery, and also reduces the risk of contamination. Removing jackets ensures that they do not come into contact with hazardous substances or interfere with the handling of materials. Therefore, it is expected that you always tie long hair back, remove all dangling jewelry, and remove all jackets in the laboratory.Rate this question:

When using sharp/pointed objects (such as probes, scissors, scalpels, etc) you should:
- A.
Make sure they are clean
- B.
Have the teacher sharpen them before use
- C.
Use them only for the laboratory experiment at hand
- D.
Pretend to "stab" your lab partner with them
Correct Answer
C. Use them only for the laboratory experiment at handExplanation
When using sharp/pointed objects, it is important to use them only for the laboratory experiment at hand. This ensures that the objects are used for their intended purpose and reduces the risk of accidents or injuries. Using the objects for any other purpose, such as pretending to "stab" someone, can be dangerous and should be avoided. It is also important to make sure that the objects are clean before using them to maintain hygiene standards. Having the teacher sharpen them before use is not necessary for their proper use in the laboratory experiment.Rate this question:
